Rollover button doesn't appear in sidebar
For some reason, I can't add a PayPal donate button to the sidebar of my website. I've been using CSS to create a rollover effect, and while it's worked on a static page of my site: < the same method doesn't appear to work in the top widget on the right sidebar of the site.
### CSS:
a.paypalButton {
display: block;
width: 207px;
height: 44px;
background-image: url('
}
a.paypalButton:hover {
background-position: bottom left;
}
### HTML:
<a class="paypalButton" href=" </a>
I even added the button to the bottom of the volunteer page (< and it works there, but just doesn't show up in the sidebar. If I write text between the a tag it places the button as a background, but that's definitely not what I want to do. | solution for your problem
1.This css code conflict with your css ( for paypal button )
#widgets .textwidget a {
display: inline;
}
and
#widgets a {
display: inline-block;
margin: 0;
padding: 0;
text-decoration: none;
}
2.put !important in display property
a.paypalButton {
display: block!important;

Add Parent to Subpage List
Below is the best code I could find for producing a list of subpages _and_ the parent page. However, it only shows the parent page while on the subpages. How do I get this to display the parent page when the user is on the parent page also?
<?php
if($post->post_parent){
$children = wp_list_pages("title_li=&include=".$post->post_parent."&echo=0");
$children .= wp_list_pages("title_li=&child_of=".$post->post_parent."&echo=0");
} else {
$children = wp_list_pages("title_li=&child_of=".$post->ID."&echo=0");
}
if ($children) { ?>
<ul class="subpages">
<?php echo $children; ?>
</ul>
<?php } ?> | <?php
if($post->post_parent){
$children = wp_list_pages("title_li=&include=".$post->post_parent."&echo=0");
$children .= wp_list_pages("title_li=&child_of=".$post->post_parent."&echo=0");
} else {
$children = wp_list_pages("title_li=&include=".$post->ID."&echo=0");
$children .= wp_list_pages("title_li=&child_of=".$post->ID."&echo=0");
}
if ($children) { ?>
<ul class="subpages">
<?php echo $children; ?>
</ul>
<?php } ?>
Try that. Just have to include the parent much like you do on the child pages, but using the current $post-ID. | stackexchange-wordpress | {

How to make Home Menu( Front Page) use index.php instead of page.php
I needed a "Home" menu item in my wordpress website, so I created a new page and named it "Home", added it to my main menu item and then from Reading Settings I selected the "Home" as Front Page.
Now the problem is, the `Home` is using `page.php` instead of `index.php`. I really need to get the home page using index.php as I have already designed the front page in my index.php
Could you please tell me how to make the home page use index.php instead of page.php | The simplest way would be to duplicate your index.php in to a file named home.php in your theme's folder.
Another way would be to create a new page template same thing (copy index.php into it) and add this at the very top
<?php
/*
Template Name: My Home Page
*/
Then head over to the page edit screen and select "My Home Page" from the template drop down

How can i add a submenu to a custom menu of another plugin?
I'm writing a couple of plugins. One plugin would be the core plugin with certain bits of functionality.
The other plugin would extend that functionality.
What I've done is in the CORE plugin, I've created a menu using "add_menu_page" and I also one submenu page in that menu.
Now, as users add more extension plugins I want to add new settings menu items under the CORE plugin menu.
I tried using add_submenu_page in the extender plugin and this adds the submenu. Problem is it gets rid of the main menu sublink in the menu. The link is added to the menu, but when i click it it does not load the right page. I get a 404.
I'm curious what command should I use to add a new submenu page to an already existing admin menu? | Always happens. I ask and immediately find the answer.
The answer is in the 2nd plugin add a "priority" of 11 to the add_action command. This plugs that submenu right in there.
Like this: `add_action('admin_menu', 'admin_submenu', 11);` | stackexchange-wordpress | {

Redirect After Delete User in Backend
How do I **redirect** to a certain page **after user deletion**?
For demonstration purpose, let's say I want to **redirect to the dashboard on user subscriber deletion**. This is what I have tried so far:
function mod_redirect_subscriber_delete($user_id) {
$user = get_user_by('id', $user_id);
$role = $user->roles[0];
if ($role == 'subscriber') {
wp_redirect( admin_url('/index.php') );
exit;
}
}
add_action("delete_user", "mod_redirect_subscriber_delete");
The above code successfully redirected me to the dashboard, but the **user didn't get deleted**.
I had also tried `deleted_user`. This deleted the user but it didn't redirect.
Any ideas?
Cheers! | You could also do this,
function mod_redirect_subscriber_delete($user_id) {
$user = get_user_by('id', $user_id);
$role = $user->roles[0];
if ($role == 'subscriber') {
add_action("deleted_user", function(){
wp_redirect( admin_url('/index.php') );
exit;
});
}
}
add_action("delete_user", "mod_redirect_subscriber_delete");
Anonymous functions (closures), available in PHP 5.3+.
Benefits:
* No need to remove the initial hook on `delete_user`
* No need to re-run `wp_delete_user()`
* You still get to hook onto `deleted_user` because we retain the user's role within the function, hence we place our closure in the `if(conditional)` statement. | stackexchange-wordpress | {

How to handle shortcodes through plugin

Redirect url in plugin to somewhere else?
I am using **WP-SNAP Extended! v1.0.0** and I want to use this alphabetical menu as a sub-menu beneath my header.

Better handling of WP-CRON server load abuse
There are multiple reports on how wp-cron is a far from ideal solution because it runs every time a page is loaded, which is unnecessary in most scenarios (one scenario in which it would be necessary is when you use _scheduled posts_ )
The common advice is to add `define('DISABLE_WP_CRON', true);` to wp-config.php then schedule a real cron job (if you have enough admin access to so).
But **as of WP 3.3, there isWP_CRON_LOCK_TIMEOUT**, which " _defines a period of time in which only one cronjob will be fired_ ".
If you run hundreds of WP installs you would have to create (and delete, when that wp install is removed) a LOT of cron jobs, which can become a nuisance. Therefore, it **seems that the best solution these days is setting`define('WP_CRON_LOCK_TIMEOUT', 900);`** (if you want wp-cron to run every 900 seconds).
**The question is: has anyone used WP_CRON_LOCK_TIMEOUT with this purpose yet? Is this its intended use?** | This is the intended use of the `WP_CRON_LOCK_TIMEOUT` constant.
When WordPress is loaded, it checks to see if a cron job is running (if cron is locked). If cron is not locked, it will try to create a lock - if the lock timeout has not been reached, no lock can be acquired and cron is not run.
If no cron job is running, and the timeout has passed (meaning a lock can be created), then cron is run. | stackexchange-wordpress | {

changing the labels inside appearance -> menus for some for the fields
So I've create a custom walker for nav menu (i am talking about the menus located at: appearance -> menu -> add a new menu. I now use the following for several things i need: `URL` `Title Attribute` `CSS Classes (optional)` `Description`
My question is how do i change the labels of those fields to be more explanatory toward my uses.
So instead of title attribute for example it will say something like `menus width`
Thanks in advanced. | I don't have the time to work out a complete solution (which could be pretty complex) but, if I am reading things right, by default WordPress uses `Walker_Nav_Menu_Edit` to create those backend menus. It looks to me like you can build your own walker for the backend and pass it in via the `wp_edit_nav_menu_walker` hook.
If you did that, you should be able to not only rename those fields but add your own fields to keep things neat. | stackexchange-wordpress | {

wordpress url with format .com/category/sub-category
I may be overlooking a simple answer here, but this one is stumping me. I am converting a site to wordpress. The current site has many pages whose URL has the format www.x.com/category/topic.
What I cant figure out/remember, is how to create a page or post with that format. As far as I know, the standard wordpress format is www.x.com/category
It is important to keep the integrity of these links, so keeping the exact destinations is a must. I would like to accomplish this without the use of redirection plugins.
Thank you in advance. | You can use structure tags in `Settings` > `Permalinks` > `Custom Structure` to form something like `/%category%/%postname%/`.

Covert Wordpress Blogname into JQuery

Accessing two databases

What makes a placeholder resizable in Tinymce?

WordPress keeps resizing my 947x947 image down to 500x500 (full-size option)

position:absolute;
width:947px !important;
height:947px;

forward domain name to particular page?
I;ve got a doman alias setup for one of my Wordpress sites and i'm trying to forward that particular domain to a page.
The 2 domains are -
www.alias.com www.actual.com When people use the _www.alias.com_ domain i want them to be forwarded to _www.alias.com/content/_
I've tried several things with the htaccess file but i think Worpdress may be ignoring the redirects or i've got it completely wrong!
ie
Redirect 301 www.alias.com
# and
RewriteCond %{HTTP_HOST} ^www.alias.com
RewriteRule (.*)$ [R=301,L]
best, Dc | First off -- does your server allow overrides in `.htaccess` files? If not, you need to get that turned on. My server has `AllowOverride All` set in its config file, which then allows my `.htaccess` rules to function.
Does `alias.com` point to the same directory as `actual.com`? If not, then you need to put a `.htaccess` file in the `alias.com` root.
Also, if I understand your requirements correctly, the `.htaccess` file for `alias.com` needs to contain this:
RewriteEngine On
RewriteCond %{HTTP_HOST} ^www.alias.com$ [NC]
RewriteRule ^(.*)$ [R=301,L]

Again this is just not for custom post type icons but all.
Basically I think through jQuery using replaceWith new icon but how can I replace an image if I don't know where its called in CSS (i.e. retina images) so I need a resolution to direct specific images in admin wp-admin and wp-includes folder.
* mydomain.com/wordpress/wp-admin/images/
* mydomain.com/wordpress/wp-inlcudes/images | The CSS is in `wp-admin/css/colors-classic.css` and `wp-admin/css/colors-fresh.css` and the `min` versions of those, including the `icons32-2x.png` ones. I can see them when I `grep` the directory. For example, `wp-admin/css/colors-classic.css:2162`.
The images themselves are in `wp-admin/images`, as you can see from the style rules, but you should not be hacking/replacing those. They will be overwritten when you update WordPress.

Total number of authors with more than one post

I need to know what is my best option for displaying the total number of authors who have at least posted and/or published something on my blog.
Currently the code is counting all the authors even if they haven't posted anything. Please let me know if there is a simple solution to this. I have looked throughout the wordpress codex and have not found a solution to this yet. | I believe that `wp_list_authors` will do what you want, sort of. You could run the function with the `echo` parameter false and count the results.
$authors = wp_list_authors(
array(
'echo'=>false,
'html'=>false
)
);
echo var_dump($authors);
echo count (explode(',',$authors));
Or, alternately, and perhaps less profligately, steal that function's `SQL`.
$authors = $wpdb->get_results(
"SELECT DISTINCT post_author, COUNT(ID) AS count
FROM $wpdb->posts
WHERE post_type = 'post'
AND " . get_private_posts_cap_sql( 'post' ) . "
GROUP BY post_author"
);
var_dump($authors);
echo count($authors);

Make WordPress size and name images for Retina.js
I'm a huge fan of the way retina.js works for high pixel density displays. Essentially, when it's loading image assets (via `<img>` or css image) it will check if there's a `@2x` suffix version of the image (eg. if there's a `logo.jpg` it will automatically show the `[email protected]` in its place if it exists.
The WordPress function `the_post_thumbnail` lets me define various image sizes, but I want to know if there's a way to have it also create versions of the images that are twice the size with the `@2x` suffix as well!

Page specific values in widgets
I have a travel guide website which I have created with WordPress which contains destination guides. On the destination guides pages I have a sidebar which displays destination statistics (currency, time zone etc).
Currently I have to create a new sidebar for each page each time changing these values.
Is it possible to create a MySQL database with these values and then insert some PHP code that will identify what country page is loaded and insert the corresponding values so that I can use a single sidebar for all pages. I am fairly proficient with HTML/CSS, but my understanding of PHP is limited.
How can I do that? | Add the data to your pages as Custom Fields, then use one of the meta functions in your sidebar to display this data.
Note that the custom fields UI may be hidden from view on pages. If this is the case, click the Screen Options tab in the upper right corner and tick the box next to Custom Fields and the UI will appear. | stackexchange-wordpress | {

Allow author to choose his featured image size
Request from a client. He wants his authors to be able to upload their image and then set it as featured, just like normal. The difference is that when setting it as featured, he wants the author to be able to choose 'small' or 'large' which will then be output appropriately on the front-end. How would you go about this? I'm well aware of how to create new image sizes in the theme, but how can I allow the author to select his image size when making his post? | You could add a meta box to the post add/edit screen below the featured image box to allow selection of size via a dropdown select menu. You could generate the list from available sizes (via `get_intermediate_image_sizes`), or just use your small/large strings. The data would be saved as post meta and you would simply `get_post_meta()` to get the selected size, then pass that result to the thumbnail function as the size parameter. | stackexchange-wordpress | {

what could cause the htaccess file to be modified?
One of the wordpress sites that I created recently went down with a _500 internal server error_. After hours of mind boggling and checking error logs, I found out that the `htaccess` files present in the user directory had been modified, with an `ss` added to the end of the file which caused the error. After changing and uploading the file, the site got back up.
I wanted to know what could have caused this? It is hosted on a godaddy server, and the permission for the file is 604. was the server hacked or did wordpress somehow write this into the file.
Thanks. | This might happen when the rewrite rules are flushed. The function `insert_with_markers()` is using `fopen()`, but _not_ `flock()`, so when two pieces of code are calling `flush_rewrite_rules()` almost at the same time, the second process can write to that file before the first one has closed it.
Check your plugins and your theme for `flush_rewrite_rules()`, especially those registering custom post types or taxonomies. Some poorly written plugins are calling this on every page load. Disable that plugin. | stackexchange-wordpress | {

Checking for existing title in custom db query not working
I want to check if the title exists before the `wp_insert_post()` is triggered.
However, the condition seems not to work as expected:
if( $wpdb->get_row("SELECT * FROM wp_posts WHERE post_title = '" . trim($titles_arr[$i]) . "' AND post_type=post", 'ARRAY_A') ) {
// title do exist
// don't save
} else {
// ...perform save code
}
And it saves always no matter if it exists.
The funny part is that if the existing title i my db is e.g.: `The best title in the world` and slug `the-best-title-in-the-world` and for example one thing from the `trim($titles_arr[0])` (I am looping the array via foreach loop) array than the slug of that post that shouldn't be saved in the first place is called `the-best-title-in-the-world-2` and if I run my scirpt again it became `the-best-title-in-the-world-3` etc. | use get_page_by_title to get post by title.
I check for it on my system
$post_exist=get_page_by_title( 'Hello world!', ARRAY_A, 'post' );
if( ! empty( $post_exist ) ) {
echo 'title exist';
} else {
echo 'title not exist';
}
Running successfully.
In your case it may be like
$title=trim($titles_arr[$i]);
$post_exist=get_page_by_title( $title, ARRAY_A, 'post' );
if( ! empty( $post_exist ) ) {
echo 'title exist';
} else {

Archive page for custom post type not working
I use a plugin called CPT-onomies to create Custom Post Types. I created a post type called "case", and set "Has Archive Page" to true, but when i try to view a single case, i just get 404'd. Same thing also happens if i try to view the actual archive, eg. "site.com/case" and not "site.com/case/case-item".
Here's a screenshot of my settings:
I've tried disabling/enablind it, no success. I also tried changing permalink structure of the whole site (from settings -> permalinks) because sometimes that doesn't update.

WordPress Loop: List All Posts by a Category & Subcategory
I want to display all post under a category and all subcategories under the parent categories. But couldn't find proper suggestion over forum or failed to understand the solution. It's possible to perform this tasks by manually adding add ID into query but for me, I need all to be autopopulated.
Need suggestion. | The `cat` and `category_name` parameters for `WP_Query` display "posts that have this category (and any children of that category)".
There are also examples of doing this in the Codex.
$query = new WP_Query( 'cat=4' );
// or
$query = new WP_Query( 'category_name=staff' );
I am not 100% sure what you mean by "I need all to be autopopulated", but if you want WordPress to "just know" what category you want there is no such ESP-based function in either WordPress or PHP. You have to tell the query what category to use, but you don't have to hard-code to `ID` or the name. It may be possible to _logically_ derive the appropriate category but you have not provided any details _at all_ about what the criteria would be for making that decision. You don't even say what page you are on, or whether you talking about the front or the back end. Without that detail a better answer is going to be difficult. | stackexchange-wordpress | {

Automatically add author's name to post_tag

function add_authors_name( $post_id ) {
global $post;
$post_author = $post->post_author; // returns the Author ID
// get the author's WP_User object so we can get the Author Name
$post_author_obj = get_userdata( $post_author );
$post_author_name = $post_author_obj->first_name . ' ' . $post_author_obj->last_name;

$option .= $page->post_title;
$option .= '</option>';
echo $option;
}
?>
</select>
</nav> | Use `wp_dropdown_pages()`:
print '<form action="' . home_url() . '">';
wp_dropdown_pages();
print '<input type=submit></form>';
You get a `select` field with proper indentation, and clicking on the button will send the user to that page.

Adding Pipes to Menu Output
My client has a menu like this image below that I am trying to re-produce for them as a WordPress Menu...
!enter image description here
My first attempt so far was to utilize the `after` parameter option for the `wp_nav_menu`.

Any suggestions? I would rather stay away from using JavaScript to hide/remove the last item.

array(
'menu' => 'footer-menu-1' ,
'after' => '<span class="navSep">|</span>'
)
); | You could build a custom Walker that would either not insert that on the last field or insert classes you could use, but if this is the only change you want that would be overkill. Hide it with CSS. Something like...

How do I add tags/taxonomy to images + a query field on page to query 'albums' (images with same tag/taxonomy)

Multiple textdomains
I have a bunch of plugins. Obviously, they all have their own unique textdomains for internationalization (i18n).
I also have a bunch of files that I include in all my plugins - I throw them all in a directory called common. This adds a dashboard widget that I want all my plugins to have, as well as a script for updating (since they don't live on the wordpress.org plugin repo).
I want to be able to just drop my common folder into each of my plugins without having to edit the files. But I'm concerned about the text strings contained inside.
Can I call load_plugin_textdomain twice, for two different domains, within the same plugin? What's the best way of handling this situation with i18n in mind?
Or will I have to go through each instance of my common files and manually change the textdomain to match the plugin? | You can call `load_plugin_textdomain()` multiple times in each plugin, but I would not do that.
Put the _common_ files into a separate plugin, for example `luke-carbis-library`. In that plugin create two simple functions for setup and loading extra files:

function lcl_init()
{
$dir = plugin_dir_path( __FILE__ );
$url = plugins_url( __FILE__ );
// maybe load necessary files and translation
do_action( 'lcl_init', $dir, $url );
}
function lcl_load( $file )
{
require_once plugin_dir_path( __FILE__ ) . $file;
}
In your depending plugins hook into your custom action:
add_action( 'lcl_init', 'depending_plugin_init', 10, 2 );

Lightbox gallery in a link
Here is what i try to get. Into WordPress a module plugin that allow me to make slideshow of image. create a portfolio name "castle" and another one name "bridge" and get 3-5 photo in each. Then, in a text, i will talk about a beautiful bridge name xyz and i like the name of the bridge to be a link, when i click this link, a modal window will appear with a slideshow (light-box evolution is perfectly what i like), then somewhere else, when i talk about the caste abc i like the name to be a link, when click, show a slideshow of thos 4 image uploaded. so the question, what plugin do that ? thanks for the help !
the way things work in the theme Barely Corporate from ThemeBlvd is AWESOME, but i think it's custom work for there theme !
I try to find a way to get the behavior i whant, i am not promoting any theme or telling this is better that that, i just have seen behavior a like to replicate for my site | You can most likely use Easy FancyBox plugin (and maybe plus NextGen gallery) to achieve the effect.
The FAQ on the Easy FancyBox documents different things you can do: <
For example, you can call lightbox of an hidden image with text link:
<a href="#hidden_image_id" class="fancybox">Castle abc</a>
<div style="display:none"><img id="hidden_image_id" src="hidden_image_url.jpg"></div>
So you'd apply this to a gallery shortcode that output element ID in it's dom:
<a href="#gallery-1" class="fancybox">Castle abc</a>
<div style="display:none">[gallery]</div>
If the native WordPress doesn't work, try the NextGen Gallery or others that would be compatible with how FancyBox tries to find the image sources. | stackexchange-wordpress | {

Is `is_sidebar_active()` deprecated, and showing error?
I **Googled** `is_sidebar_active()`, used by several WordPress trainer, but I came to the decision, the function's surely deprecated. But unfortunately I found no mention, even no entry in WordPress Codex.
As a Wikipedian, I also edit the Codex sometime, but need the confirmation that, `is_sidebar_active()` IS DEPRECATED, and `is_active_sidebar()` is ON now.
I used `is_active_sidebar()` instead of `is_sidebar_active()` in my theme and it's working fine.
But I need a confirmation. Anybody? | `is_sidebar_active()` is not a WordPress function. Do not use that. This is probably a typo.

What is the use of to_ping and pinged column?
Can anyone explain or show a reference for the use of `to_ping` and `pinged` column in the wp_posts table? It seems that my Googling skills have failed me.
I wanted to do an experiment using the `pinged` column to save the `term_id` of a term that is related to this post record.
I know that the proper way is to use custom field instead, but I wanted to reduce the mysql `inner join` in the WP_Query calls.
Thank you in advance. | * `to_ping` is a list of URLs WordPress should send pingbacks to.
* `pinged` is a list of URLs WordPress has sent pingbacks to.
Do not use these fields for something else. They are parsed many times in core code (69 matches for `to_ping`); their format is fixed.
You cannot reduce the query load by using these fields, because _all_ post meta fields are fetched in one rush per post. So it doesn’t matter if there is one more or less. | stackexchange-wordpress | {

Is there a way to password-protect part of a post?

I suppose I could do entirely manually without WordPress functions at all but I'd like to know if there was a WordPress solution. | I would do it the other way around: Put the always visible text into a custom field per metabox, and protect the post content with a password.

{
the_post();

Paging with category page
I have created my category.php to display all the posts (i am using custom post) in the category.
By default, it's displaying 10 entries, and when i scroll down, i wanna fetch the next 10 entries with jquery infinite scroll. The problem is when i added the following lines to my template, it shows the link(href) to "/category/category_name/page/2" which returns 404.
<?php if($loop->max_num_pages > 1) : ?>
<nav id="page-nav" class="navigation" role="navigation">
<?php previous_posts_link('≪ Previous', $loop->max_num_pages); ?>
<?php next_posts_link('More ≫', $loop->max_num_pages); ?>
</nav>
<?php endif; ?>
How should i set my link (href) so that it fetch the next 10 entries in the same category?
Thank you. | `category.php` is the main category archive template file, which is auto-magically loaded by WordPress for category archives. In that case, use the `pre_get_posts` hook to alter the main query for this page and you shouldn't have trouble with the pagination.
function pregp_wpse_100602($qry) {
if (is_category() && is_main_query()) {
// no idea what conditions you want, but below is a sample
// $qry->set('posts_per_page',5);
}
}
add_action('pre_get_posts','pregp_wpse_100602');
As is, you've created a second loop-- `$loop->`\-- for the page. The pagination functions do not work well when you do that. Those functions depend on the _main_ query, which you are not using. I believe that is the root of the problem.

wp_trash_post not firing
I want to call a function when a post is placed into the trash. I want to do something more complicated than the following, but have simplified to what's below just to see if it'll work and it doesn't.
function gna_my_function() {

Thanks | There are two hooks you should be considering-- `wp_trash_post` and `trashed_post`. Based on your statement that you want this to work "when a post is placed into the trash" I'd suggest the latter is the better hook, since it runs _after_ the post is successfully placed in the trash.
I hate to suggest this as an answer but I do think it explains why your function does not appear to output anything. When WordPress saves a post a request is sent to the server, the request is processed, and then the browser is redirected back to the originating page. That means that you cannot always see dumped/`echo`ed output without killing the script. I believe the following should make your apparently debugging function do what you expect it to, provided that you have "trash" enabled.

echo 'trashed '; die;

Can I use an array to create multiple tables?

What's the best way to create a new design for other pages?
I want to create a different design for all new and existing pages, with the exception of the frontpage.
The new design includes another subheader, container, and an extra subfooter.
My guess was to edit footer.php/header.php in my child theme directly, and create seperate subheader/footer/container for these pages, and apply them as follows:
<?php if ( is_home() || is_front_page()){
<div class="subheader_front"></div>
}
else {
<div class="subheader"></div>
} ?>
Is this a correct way of applying a new design, or could this be done simpler? | You can create template files named `front-page.php` and `home.php`, which will be automatically loaded. See the Template Hierarchy for details.
You can also set up different headers for different template files. For instance, if you have a Home Page template `home.php`, you can have a separate header file loaded in it.
In your `home.php` file, you can pass a parameter to your `get_header()` call -- for example, `get_header( 'home' )`. This will look for a file named `header-home.php`, and load it if it exists. Failing that, it will load the default `header.php` file instead. You can do the same with your `get_footer()` and `get_sidebar()` calls.

Front-End Interfaces Without Shortcodes
So, I consider myself a "advanced novice" at WordPress development but I still do not have the concept of pages and templates fully understood. I'm having an issue with a feature I'm attempting to include in my plugin and discovered that it's possibly due to the way I am displaying my interfaces on the pages (via shortcodes). Without customizing a theme, how would one display interfaces (grid with interactive functionality) on the font-end? The way my plugin works currently is that it uses shortcodes to house all of my php code that performs the work to display my interfaces and those shortcodes are added as content to pages that my plugin creates upon activation. Is there another way to do this? | What you're doing is, in my opinion, the best way to accomplish this. First off, the pages are a good way to go, because they give users the ability to customize parts of the page like title, meta fields, etc. You don't have to use shortcodes per se, you can filter `the_content` for these pages, but shortcodes offer additional flexibility. For instance, your users can call them directly in a template file if they don't want to use pages, or they can use them in other posts if they want to use a custom post type or something. Anyway, nice work, this is a great way to go. That doesn't solve your issue, but you can probably cross it off your list. | stackexchange-wordpress | {

Problem with $post_id object's property
Dealing with retrieving CPT metadata I find out two methods `get_post_meta()` and `get_post_custom()` to return the value(s) of the custom fields with the specified key from the specified post. Both methods are passing the `$post_id` as first parameter to access global `$post` object's ID property.
Now my question is, how does WordPress figure out which CPT or POST we are asking for? For example at following example how does WordPress understand which post we are talking about
function save_options(){
global $post;
if (!isset($_POST['price']) || $post->post_type != 'product')
{
return $post;
}
update_post_meta($post->ID, "price", $_POST['price']); | I consider this question to be borderline unanswerable. It really depends on context.
In your example `$post` is whatever that `global` has been set to. That is pretty general, pretty obvious, and not really saying much but without knowing the context in which this code executes it is hard to give a better answer.
That variable is set for each post in the Loop by `setup_postdata` or `the_post` and it is set on some back-end pages in similar ways, based ultimately in `$_GET` or `$_POST` data whether that `$_GET` or `$_POST` data contains a post ID or components of a query.
Many of the hooks and filters that you use are passed that value so it is not always necessary to grab the global directly. | stackexchange-wordpress | {

Is there a way I can include the localized files into my skeleton git repository? | > Download your languages files from the SVN repo...
I would strongly advise against this. The repo, as storage of language files, is being discontinued, in favor of Translate WordPress. Right now, you have no guarantees that the repo has a current version of the file.
The current method of getting language files is either to download (export) them directly from Translate WordPress individually (core, admin, network and themes). You can access that directly with something like:
< (for the .mo, replace with format=po for the .po)
Above examples are for core files only, you'd need to repeat that for /wp/dev/admin/de/default, wp/dev/admin/network/de/default, and the themes.

Too many connections to server
I'm facing a really weird problem with my wordpress/server.
Sometimes when I add media (images) to a new post, and then try to submit this post, instead of my website I got the information in browser:
connection rejected by server
I contacted my hosting provider to solve this problem and they claim that my wordpress is generating too many simultaneous connections to server and that's why my IP is being blocked (usually for about 48 hours). For everyone else the site is working perfectly fine.
Is it possible that adding images/submitting the post is generating more than 18 connections to server (that's the limit that my hosting provider has on its servers)?

I'm using Woothemes Canvas and my own child theme.
I can remove post-meta globally by using an empty function:
function woo_post_meta() {}
This works fine but I only want it to work for 3 categories
I know I need to somehow use is_category butI'm not sure of the syntax, I tried
if ( is_category(4,5,6) ) {
function woo_post_meta() {}
}
but that doesn't work, i'm not sure how to correctly write a function within a function.
Then how do i also remove comments from those categories? or should I make custom content type to do all this? | Here are some ideas:
**a)** Instead of
is_category(4,5,6)
which checks if a category archive page is being displayed (see here), you can try
in_category(4,5,6)
or
in_category( array(4,5,6) )
that checks if the current post is assigned to any of the specified categories (see here).
**b)** You could also try
function woo_post_meta() {
if ( in_category(4,5,6) ) {
return "";
}else{
// the original woo_post_meta() code here.
}
}
**c)** If the original `woo_post_meta()` contains an output filter, than we could add a custom filter with the above category check.
**d)** If you write your own child theme, you could replace the template tag:
woo_post_meta();
with
if ( !in_category(4,5,6) ) {
woo_post_meta();

User Meta stuff
Ok I am trying to make a page the list user meta.
<
The part I am stuck on is
`$our_children = get_user_meta ($user_id,"our_children");`
it is a meta field with an array in it.
`a:1:{i:0;a:2:{s:4:"Name";s:6:"Elisha";s:3:"Age";s:2:"13";}}`
How do I display the data in that array?
`//foreach ( $our_children as $children ) { echo '<tr><td>'. $our_children-> Name .'</td><<td>'. $our_children-> Age .'</td></tr>'; //}`
Doesn't seem to work? | You have a few PHP issues preventing output-
1. it appears your foreach is commented out with `//`.
2. you do `foreach( $our_children as $children )`, but then you use `$our_children` instead of `$children` inside the foreach.
3. `$children->Age` is for accessing an object's property, but what you have here is an array, so it should be `$children['Age']`
-
foreach ( $our_children as $children ) {
echo '<tr><td>'. $children['Name'] .'</td><td>'. $children['Age'] .'</td></tr>';

Get Original Dimension Featured Image on the homepage

Per that Codex entry `$size` can take string values of "thumbnail, medium, large or full". You need "full" to get the full size image, which ought to be the original.

Why get_page_template() doesn't show taxonomy template file name?
I made a custom taxonomy called - `work-category` and a template file for it called - `taxonomy-work-category.php`. That part work just fine.
For a purpose I did put `get_page_template()` in that `taxonomy-work-category.php` file to get the current template file name. But it does print out as `page.php` (with full path ofcourse). I was expecting it to print out `taxonomy-work-category.php`.
Even when I'm certain it is printing out from a custom taxonomy template file - Why doesn't `get_page_template()` function doesn't returns the taxonomy template file name? | `get_page_template` returns the template of the current active post/page. You're not on a post/page though, you're in a listing/archive.
When you get `page.php` what you're seeing is the template of the first post/page. The taxonomy listing itself is not a page, it's a listing, and so it makes no sense for it to have a page template, as it is not a page.
See here for an answer that should do what you want:
Get name of the current template file
this may also work:
/* show me what the body class will look like */
echo body_class() . "\n";
/* make sure i've got $template */
global $template;
/* print the active template path and filename */

Using FlexNav with WordPress
Has anyone managed to get the FlexNav plugin - < \- working with WordPress?
I've got an HTML version of the site working fine, but I'm running into trouble when integrating with WordPress as WordPress uses it's own classes, ids etc. on menu items and this seems to override the flexnav plugin.
I'm wondering if I should be trying to replicate the menu structure that the plugin creates using a custom walker function, or just re-writing the CSS with what WordPress gives me?
Any advice appreciated!
Thanks | You don't need a custom walker function. You can alter wp_nav_menu like this:
wp_nav_menu( array(
'theme_location' => 'primary',
'menu_class' => 'flexnav', //Adding the class for FlexNav
'items_wrap' => '<ul data-breakpoint="800" id="%1$s" class="%2$s">%3$s</ul>', // Adding data-breakpoint for FlexNav
));
and proper script init should be:
jQuery(document).ready(function($){
$(".flexnav").flexNav({
});
});
Drop menu button somewhere outside navigation:
<div class="menu-button">Menu</div>
But still does not work. As toscho refered, FlexNav needs a small modification to work in WordPress. Take a look this mod here <

How do I cleanly override a plugin's CSS with a child theme?
I have taken it upon myself to adhere to WordPress conventions so I can have a clean, sexy child theme. However, I am unsure how to proceed on a certain issue.
I would like to override the CSS for some plugins in my WordPress website, and this wonderful post was a great step in the right direction. My only concern is that I would like to do everything I can to **avoid overriding** the `header.php` file in my parent theme in order the do this.
Is there another wonderful way to do this? Thanks for your help!
**Update** :
As was pointed out by another user's comment, this is in fact dependent on how the plugin implements its styles. This aside, assume that the plugins do provide a way for styles to be implemented in the `style.css` sheet of the child theme, or, in my case, a separate `styles` folder linked to that `style.css` sheet.
I also know I can use `!important` all over the place, but this is generally frowned upon. | If the plugins are correctly adding their styles via `wp_enqueue_style`, you simply need to dequeue them:
function wpa_dequeue_style() {
wp_dequeue_style( 'plugin-style-handle' );
}
add_action( 'wp_enqueue_scripts', 'wpa_dequeue_style', 100 );
Whether or not this works depends on how and where the plugins are adding their styles, so there's no absolute answer without knowing specific methods the plugins in question use.
EDIT- another option that doesn't involve removing the styles entirely is to enqueue your own styles with the plugin styles as a dependency:
wp_enqueue_style(
'my-styles',
get_template_directory_uri() . '/mystyles.css',
array('plugin-style-handle')

Multisite with a single, shared custom post type, while retaining site URL
Small multisite setup, two very different sites, both need to access an `event` custom post type. I don't want to duplicate posts (there are some plugins that "broadcast" a post to the network).
`switch_to_blog(1)` will get me part way there, where `blog 1` is the "master" blog that contains the `event` data, as far as archive-style pages that list all the events. But my concern is that the URL/permalink of the event, when viewed from `blog 2` will point to `blog 1`, and following that permalink will then take the user to the other blog, confusing the user.
Is there a solution (possibly using rewrite) that would allow an event post at `//blog1/events/event1` to appear as `//blog2/events/event1` when viewed from `blog 2`? | There are two options:
1. Register the CPT on blog 2 with `'show_ui' => FALSE`. Hook on blog 1 into `save_post` and copy the data to blog 2.
* Pro: You can search in those posts. Correct templates will be used automatically.
* Con: Duplicated data are always a little bit … dirty.
2. Register an endpoint with an URL scheme like the CPT on blog 1 (`EP_ROOT`).

<?php the_time('F j, Y'); ?> at <?php the_time('g:i a'); ?> | You can get the post's creation date/time and compare it to the current date/time.
global $post;
$now = time(); // Current time in seconds since Epoch
$post_created = strtotime( $post->post_date ); // post's creation date in seconds since Epoch, so we're comparing apples to apples
$one_day_in_seconds = 24*60*60;
if ( ( $now - $post_created ) < $one_day_in_seconds ) {
echo human_time_diff( get_the_time('U'), current_time('timestamp') ) . ' ago';

Open Graph in posts loop page
I have a loop where all the posts have their own like button, when i click it the facebook window appears but it does not show the right post thumbnail. I think this is normal because in a posts loop the thumbnails are multiple so the script can not figure which one goes where - on the contrary the like button works perfectly on my single post pages.
So my question: is it possible to have the facebook like button work correctly on a loop page so that it grabs the right post thumbnail even if there are, say 10 posts in that page?
Maybe i should have multiple Open Graph metas, a set for each post in the loop, but i guess this would just cause a mess, is there something that i can do? | As far as I know this is not possible the way you're trying to get it to work. You can specify an image for Facebook to use in the `<meta>` tag, but that's about it.
One thing you can try is use JavaScript to invoke the Facebook feed dialog. It has a `picture` parameter:

> The URL of a picture attached to this post. The picture must be at least 50px by 50px (though minimum 200px by 200px is preferred) and have a maximum aspect ratio of 3:1

Removing parent slug from URL on custom post type

I'd rather not use an additional plugins to accomplish this. I'm currently delivering the CPT via a plugin, which also registers a custom taxonomy. | In a quick test, I was surprised to find that this works out of the box. That is, the canonical URI for a child post still has the parent in the path, but the child post works just as well without it (doesn't 404, doesn't redirect).

Redirect to post with only post ID in the URL vs post_type/post ID
The title may be a little confusing, I don't know how to word it to be short.
Right now my permalink structure is `/%post_id%/%postname%` so the final URL is `/post_type/%post_id%/%postname%`.
When I go to `domain.com/post_id` then it redirects to `domain.com/post_type/%post_id%/%postname%` but when I got to `domain.com/post_type/post_id` it doesn't redirect but shows the correct post.
I'm not sure how to make it work the way the default redirect works. | I used the following plugin lately:
<
to get post ID based shortlinks, like ` That worked very well for me, with a couple of custom post types too.
On a sidenote, I'm not sure about your permalink structure, especially because `%post_id%` and `%postname%` are both uniquely referring to the same post, but on the other hand you might have a good reason for choosing the structure exactly like that.
In reference to Matthew's comment i used the following in my `register_post_type()` call in above mentioned project:
'rewrite' => array( 'slug' => '/%post_type%',
'with_front' => false,
'pages' => true,
'feeds' => '',
'ep_mask' => 1 )
It's just the rewrite part and of course you have to replace `%post_type%` accordingly - I also should mention that the settings for the permalinks would be set to just `%postname%`. | stackexchange-wordpress | {

Remove old custom field after import
I have imported a set of posts to a new Wordpress install recently. This OLD set of posts had a set of custom fields attached to it (via post_meta using the ACF plugin). The new installation has almost the same fields, with a couple of exceptions. On the posts that have the old (no longer used) custom fields the back-end is still showing those fields when I go to edit the post, even though I do not have them set up in the CURRENT Wordpress installation.
I can only assume this is because the values are in the database (via the import) so Wordpress is displaying them.
How would I go about removing these custom fields and values from the database safely so they do not show up in the post edit screen anymore on the new install? | As far as I know the custom key-value pairs are kept in the `wp_postmeta` table. You can simply examine (and delete) them in the database directly.
SELECT *
FROM wp_postmeta
WHERE meta_key LIKE '%you_old_key_name%'
The ACF configuration of the fields is another story, but you say that you don't even have the field in the new setup, so you shouldn't worry about that one.

How can I make a page for post formats (specifically quotes) in wordpress 3.5
I am trying to create the ability for the end user to add quotes (testimonials) as posts. So far, so good. I have enabled the 'quote' post-format in my theme. So the ability exists to enter said testimonials, and I have even figured out how to show some random quotes in the sidebar. The next obvious step is to have a "testimonials" page, where all of the quotes are archived, over time. It needs the ability to be a page, which means that the client can alter the text in the page, and it can be linked to, in menus and on pages. Following the opening (editable) text, would be a list of the quotes, like an archive page, except that the entire quote would be on the page. For that reason, it would at some point, have to become paged. Any ideas? | Because post formats are a **taxonomy** , WordPress handles the archive index page automatically, using the slug `type` as the taxonomy, and the post format type itself as the taxonomy _term_ ; e.g:
www.example.com/type/quote
If you want to customize the appearance of this **taxonomy archive index** page, you would modify the appropriate taxonomy template file, as per the Template Hierarchy:
* `taxonomy-post_format.php` for _all_ post format types
* `taxonomy-post_format-post-format-quote.php` for the _quote_ post format type. | stackexchange-wordpress | {

Pages not using permalink
I recently changed my theme from one custom theme to another custom theme.
There were previously pages that used template files (i.e., "Blog" page uses Blog template) and now that I've changed themes the pages are not redirecting as usual.
I tried importing the old data and then each page was created twice (i.e., Blog (with permalink blog) and Blog (with permalink blog-2)).
I've tried deleting both pages and choosing to deleted them permanently.
I also tried re-creating the page using the template file (naming it "Blog" with permalink blog), but I continue to get the error:
Index of /blog
Apache Server Port 80
It seems that WP is directing to the folder /blog instead of the page with the permalink blog.
If I change the title of the page (i.e., "Test" with permalink test) and apply the template file the issue resolves. But I would like to keep the same links as the previous design.
.htaccess issue or WordPress issue? | If you're getting
Index of /blog
Apache Server Port 80
instead of a `404` page, you might be having a folder called `blog` in on your server. Try deleting or renaming that folder if you're not using it.
