Randomize Users
I'm trying to randomly display my users and I was wondering if I could edit the answer on this page to suit my needs (multiple users instead of a single user): Sidebar random author spotlight
Here's my code (I can easily switch to `WP_user_query` if need be)
<?php
$args = array(
'fields' => 'all_with_meta',
'exclude' => array(1),
);
$users = get_users( $args );
foreach( $users as $user ) { ?> | I don't see an "orderby Rand()" parameter for either `get_users` or `WP_User_Query`. There is a filter called `pre_user_query` that could be used but I am not sure I see the benefit of that when `shuffle` will randomize the array you already have.
$args = array(
'fields' => 'all_with_meta',
'exclude' => array(1),
);
$users = get_users( $args );
shuffle($users);

Fancybox plugin: triggering on href attribute
I want to show a pop up when clicking on an anchor with a specific url. I've tried the following code in the extra calls tab but it doesn't work.
jQuery("a[href='
'transitionIn': 'elastic', 'transitionOut': 'elastic', 'speedIn': 600, 'speedOut': 200, 'type': 'iframe', 'height': 800 });
I assume the problem is in the selector since I have another script where the code beyond the selector is identical to the above, and it works perfectly. I tested the syntax of the selector at W3 schools doing a simple add class test and the syntax appears to be correct.
Any suggestions as to the source of the problem? Syntax, perhaps Fancybox has trouble with certain selectors?
Any advice would be appreciated.
Thanks. | jQuery('a[href^="
Try this.
<script type="text/javascript">
jQuery(document).ready(function($) {
jQuery('a[href="
'transitionIn': 'elastic', 'transitionOut': 'elastic', 'speedIn': 600, 'speedOut': 200, 'type': 'iframe', 'height': 800 });
});

wp_enqueue_script( 'my-scripts' );

Dynamic image crop in WP 3.0+?
Since WP 3.0 does not support hard crop anymore (the only way to crop is in media manager), how am I suppose to dynamically crop my thumbnails? I don't want to crop them manually one by one... | <

$image->save( 'cool_image.jpg' );
}
Repalce cool_image.jpg with a variable holding the path to the image you want to edit. Not a copy and paste solution but should put u on the right track. There is a crop function.
crop( $src_x, $src_y, $src_w, $src_h, $dst_w = null, $dst_h = null, $src_abs = false );

Make title field multiline in the add new custom post page?
I have a custom post type named "news". The title field holds the raw news and i added another custom field that holds the published news. The published news field is a text area so i can use enter button when editing. Is there a way to make the title field behave like that, to edit in multiline?
thanks | You shouldn't really be using the title for chunks of content. That title is used for things like generating `URL`s, for example, and it could be used for all kinds of things by the theme and plugins. That is almost certainly going to cause trouble.
I'd suggest you register your post type without 'title' support and create a custom meta box for you "raw news", or just use the title for it is meant for-- a title.
To answer the question directly though, the markup that generates the title section is hard-coded. You can't alter it.

Publish and save specific postmeta to a filtered post_type
I have multiple plugins with different post_type(s). When I save or publish, all of the `custom_post_meta` that belong to one specific `post_type` are also saving.
I'd like to filter by `post_type` so that the `custom_post_meta` will only save in a specific `post_type`.
So my question is, if you have multiple plugins:
**How do you save a specific postmeta** to a specific `post_type`?
Would you just say:
if (post_type=="my_post_type") {
add_action('save_post','save_my_meta_box_to_postmeta');
add_action('publish_post','save_my_meta_box_to_postmeta');
}
And how do you **get** the `post_type` value? | Do the check inside the callback. `save_post` will pass you both the post ID and the post object:
do_action('save_post', $post_ID, $post);
So...
function save_my_meta_box_to_postmeta($post_ID, $post) {
if ('yourtype' === $post->post_type) {
echo '<pre>';
var_dump($post_ID,$post);
echo '</pre>';
die;
}
}
add_action('save_post','save_my_meta_box_to_postmeta',1,2);

Adding line breaks to nav menu items
I need to add line breaks to the nav menu item titles. I didn't realize this was a problem as when I am logged in as a Super Admin, I can add `<br/>` just fine, but apparently regular-level admins cannot.
I've read over this post Custom Menus Description Stripping HTML Tags
but I'm fairly convinced the tags are being stripped on on save/update, so I am not immediately seeing how a Custom Walker is the solution, but my brain is pretty well shot today, so it might be obvious.
There also doesn't seem to be any sanitation happening in `wp_save_nav_menu_items()` or `wp_update_nav_menu_item()`. | Following the hint from @Rarst regarding safe characters here's what I ended up doing:
function wpa_105883_menu_title_markup( $title, $id ){
if ( is_nav_menu_item ( $id ) && ! is_admin() ){
$title = preg_replace( '/#BR#/', '<br/>', $title );
}
return $title;
}
add_filter( 'the_title', 'wpa_105883_menu_title_markup', 10, 2 );
**Edit** : Also per Rarst's comment I've replaced the `preg_replace` with `str_ireplace`
function wpa_105883_menu_title_markup( $title, $id ){
if ( is_nav_menu_item ( $id ) ){
$title = str_ireplace( "#BR#", "<br/>", $title );
}

User profile update author

How do I add JavaScript that will execute on all my sites in Multisite?
We are creating an internal network of sites using MU and there are some small things we would like to have globally on all the sites without having to add them individually for each site. I would like to add a block of JavaScript and CSS that will execute on every site. What's the best way of going about this? | Your answer, Kyle, is the `mu_plugins` folder. Create it within wp-content. Any php file put in here will be automatically loaded into ALL multisite blogs (or any non-multisite blogs).
This is a great area to put plugins vital to the site working, or shared functionality such as custom post types, taxonomies, filters, etc. Really anything! The main bonus here is when updated said "shared" files, you don't have to do it in every single theme that utilizes it! It'll be available for all themes, on all sites.
If you want to sort your stuff within `mu_plugins` just put everything in a nice folder structure, and create a `index.php` or `load.php` in the root of `mu_plugins` where you can load everything in.

How to fake a Wordpress login?
As many of you know WPEngine don't support PHP SESSIONS unless the user is logged in. In that case WPEngine start taking consideration of PHP SESSIONS and the software based on hybridauth like Wordpress Social Login or Wordpress Social Invitations will work ok.
So my question is : There is a way to fake a Wordpress login? | You could create a dummy user (with no rights) and log in every visitor using this dummy user. This could be done pretty easily:
wp_set_auth_cookie($uid, true);
wp_set_current_user($uid);
But in my opinion that's a rather flawy workaround.
Your main problem is that all pages for not-logged-in users come from the page-cache. That also means that all users get the same html output as long as there is page-caching active. So there can't be any difference to your pages based on the visitor. All visitors get the same output.
A better way would be to create a ticket at WPEngine and ask them to disable page-caching for your site. That's actually also the way they suggest on the page you linked to. | stackexchange-wordpress | {

Does WordPress Need BuddyPress to Handle Large Amounts of Users?
I understand that technically there can be 18446744073709551615 users (db limitations). But I heard at a talk that the vanilla install of WP in actuality can't handle many users that well due to caching issues, especially if you add user_meta. Can someone confirm this?
The speaker recommended that to make wordpress more able to handle the large amounts of users it's a good idea to install BuddyPress, but honestly the code is a mess and there is little documentation. So I'm considering scrapping that and going vanilla again.
Does anyone have any expertise and can shed light on this? | I wouldn't advise you to use BuddyPress if you don't have a specific use for any of the special features that are offered by BuddyPress.
From what I've seen from the BuddyPress core is, that it doesn't change any core existing WP functions. So I don't believe that BuddyPress actually changes the handling of user_meta. I seriously doubt that BuddyPress changes anything (wether to the good or to the bad) in regards to the performance of the user handling in Wordpress.
Also from my experience (had up to 15.000 users in one install until now), the performance is still good with vanilla WordPress. No performance degradation measurable. Especially if you have object/database-caching in memory.
If you reach the performance limits of the core API functions you could still easily change your application to hand-crafted and tuned SQL queries and optimize your query and index structure to deliver maximum performance for your specific user_meta queries. | stackexchange-wordpress | {

index.php file in wp-content/themes/ folder
I was manually uploading a theme im working on to my wordpress install tonight when I noticed a index.php file in my themes folder. I opened the file and it contained only the following three lines of code:

So what I am getting at is, should there be a index.php file in my wp-content/themes/ directory? Or is it possible someone put it there. OR! Now that I think of it, maybe the file was accidentally uploaded by myself, and then a "hacker" or someone who got access to the directoy changed the contents to include only that one comment, hoping it would break the site.

Width 100%: Aspect ratio of image
If I add an image to a post, WordPress hardcodes `width` and `height` attributes to the `img` tag.
I added `max-width:100%` to my CSS, but of course, if my browser window gets smaller, the resized image gets stretched in height.
What can I do about it?
Is there a way to:
**A** : Solve it with CSS (I would prefer that)?
**B** : Forbid WP to hardcode width and height?
or
**C** : Is there a common way of dealing with image widths, I'm not aware of? | **A** \+ **C** :
img.resize-proportionally {
max-width: 100%;
height: auto;
}
As an aside, for the above to work, you shouldn't attempt **B**.

Get all terms, including unchecked, or get the terms outside loop
I'm trying to return all the terms for a particular taxonomy (so eventually I can create a link for it). At the moment, this function I've written only returns terms for the current post. How can I just return a list of all of them?
<h2>Get terms</h2>
<?php
$taxonomies=get_taxonomies('','object');
foreach($taxonomies as $tax){
echo "<h2>$tax->name</h2>";
$terms = get_terms($tax->name);
foreach($terms as $term){
print_a($term->name);
}
}
?>
Just for a bit more detail, the site is about wine, and one taxonomy is grape type. If the current wine is a Chardonnay, it returns "Chardonnay", but I'd like it to return "Chardonnay, Merlot, Pinot Grigio" etc.
The `print_a` function is just a `print_r` wrapped in pre tags.

How would I get a list of posts from a custom post type
I know the query method that you would use, that's not what I want. I could query the post type, then do the if statement with the while statement and go from there, but I am trying to populate a drop down with post titles. Thus I need an object.
What I have, which isn't working - there should be two posts in this object but their isnt, it comes back NULL, is:
$args = array('post_type' => 'carousel', 'suppress_filters' => 0, 'numberposts' => -1, 'order' => 'ASC');
$content_block = get_post($args);
var_dump($content_block) // NULL
What would I do to get all the posts of the type `carousel`? which I know for a fact has 2 posts in it. I can go to `site.com/carousel/ctitle` to see `ctitle`'s content. But when I try the above I get `NULL` | $args = array(
'post_type' => 'carousel',
'suppress_filters' => 0,
'numberposts' => -1,
'order' => 'ASC'
);
$content_block = get_posts( $args ); // there was a typo in this line
var_dump($content_block); // it should work fine now
PS. I'm not sure why do you need "an object" and you can't do it with custom WP_Query. In the end, `get_posts` function builds custom WP_Query and returns result of it... ;)

After I set the title, it over-wrote all the titles for the individual pages
A few days ago I set the title tag for my home page by doing this:
Settings => General
but it turned out that this didn't just change the title of the home page. It actually changed the title of every page on the site to that one title.
What is the way for me to correctly set the title for the home page, and not over-write the titles for all the individual pages?
EDIT:
To explain things further. I set the title tag to be this:
<title>0xdata - Open source software engineering developer community and events</title>
But now the individual pages have titles like this:
Title - Open source software engineering developer community and events » Open source software engineering developer community and events
Thank you! | WordPress sets the titles of your pages using tags which is normally set int he header.php file of your theme. In my themes I use:

Wordpress custom search by post type
Is it possible:
If post type is post, search only in post title. If post type is page, search only in post content.
I was trying in any ways but didnt worked, maybe someone could help me ? | Yes, it is possible. You will have to use your custom SQL query though.
Use `posts_where` filter to modify the query.
function posts_where( $where ) {
if( !is_admin() ) {
$where = <YOUR CONDITION>;
}
return $where;
}
add_filter( 'posts_where' , 'posts_where' );
Your condition should look something like this:
`post_status = 'publish' AND ((post_type = 'post' AND post_title LIKE <QUERY>) OR (post_type = 'page' AND post_content LIKE <QUERY>))`
You should also make sure, that you will modify only main query and not all of them. You can add filter just before main query (i.e. using `pre_get_posts` action) and remove it just after or even inside this filter, I guess. | stackexchange-wordpress | {

How to target specific user role?
I'm trying to place a simple bunch of codes to redirect the 'Subscribers' only, to the home page (or a desired page) after login. I thought to use `if( current_user_can('read') ):`, but that's a global capability, will be applicable for all the other roles too. So I tried `get_role('subscriber')`. Here are my `functions.php` codes (thanks to Len):
function subscriber_redirection() {
global $redirect_to;
if( get_role('subscriber') ) {
if ( !isset( $_GET['redirect_to'] ) ) {
$redirect_to = get_option('siteurl');
}
}
}
But it's redirecting the administrators too!
* **How can I target only a specific user role for a purpose?** | `get_role` is just going to return information about the role. It isn't going to tell you if the current user has that role. Use `wp_get_current_user` with a check something like this:
function subscriber_redirection() {
global $redirect_to;
$user = wp_get_current_user();
if (in_array('subscriber',$user->roles)) {
// user has subscriber role
if ( !isset( $_GET['redirect_to'] ) ) {
$redirect_to = get_option('siteurl');
}
}
}

Show one same template for two category
I want to show `gallery.php` template for category. I am currently using `category-15.php` and `category-19.php` technique.
I want to redirect category 15 and 19 to `gallery.php` instead (one template for two category). And I want to use a simpler technique. It can be by using `functions.php`.
How can i do it? | You can do it in many ways.
Two solutions I recommend are:
## 1\. Editing category template
Just edit your `category.php` template and put if statement in there:
if ( is_category( array(15, 19) ) )
get_template_part('category-15-19');
else
get_template_part('category-all')
Then just put code for category 15 and 19 into `category-15-19.php` file and code for other categories into `category-all.php` file.
## 2\. Using `template_include` hook
Add filter to `template_include` hook. It should return template name that should be displayed by WordPress.
function my_categories_template($template_name) {
if ( is_category( array(15, 19) ) )
return 'category-15-19.php';
return $template_name;

Do more action after login successfully

function set_blog_session(){
$_SESSION['blogger'] = get_current_user_id();
wp_redirect(" for test
}
add_action('wp_login', 'set_blog_session');
But I got nothing.
First, `get_current-user_id()` always returns `0`.
Second, **no redirect at all**.
Whats going wrong? | You should use `exit` after using the `wp_redirect()`:
From the Codex:
> wp_redirect() does not exit automatically and should almost always be followed by exit.
* * *
For your hook, you could pass a parameter in your callback function to get the user login and then use `get_user_by()` to get the ID.
function set_blog_session($user_login){
$user_obj = get_user_by('login', $user_login );
$_SESSION['blogger'] = $user_obj->ID;

Put a link to a category round a hard coded A HREF

UPDATE: Could it be called using the SLUG and if yes have is this done please. | The "page" in WordPress usually refers to a "PAGE page", as in only post of `page` post type. Not any _page_ of the site in general.

If `cooking-sauces` is slug of a _term_ that belongs to custom _taxonomy_ (as opposed to native _category_ taxonomy) you will probably need to use something like:

failed to load wp-admin/admin-ajax.php
I'm getting this strange issue. Everything was working fine last day. Now suddenly none of my ajax requests work. The problem is (i found that in firebug console):

So somehow the request to the `admin-ajax.php` file isn't successful. I have cross checked these things:
1. the url to `admin-ajax.php` is correct and no issues there
2. its not just 'my own scripts' which doesn't work, i've buddypress installed and all ajax requests from buddypress also give the same error
3. i directly typed in the url of `admin-ajax.php` into browser and instead of getting 0 (the expected output), google chrome says 'no data received'.
Is it some configuration on server end?? If yes then what do i say to the hosting support guys?
BTW, if it matters, the site is hosted on wpengine..
Any help is really appreciated
**UPDATE :** the browser dev tools screenshot : !enter image description here | Yes finally the problem was that the hosting provider had blocked the admin-ajax.php file saying that this file was receiving too many request, and requests to this file bypasses cache , hence it was causing problems on server :)

But yes, it should be possible. Just make sure you don't use it to early (when `is_admin()` return incorrect value).
**EDIT**
The code you've posted here should work just fine. Of course you have to make sure that code placed in `functions_admin.php` is written correctly (for example you have to take care of using global variables in correct way).
To test if this is included, just add `echo 'alamakota';` in first line of this included file and check if 'alamakota' is showing on every admin page (it should).

CSS Classes (optional) on menu is not showing

It is hard to say for sure without seeing the code for that custom walker but you can remove the `'walker' => new sweetdate_walker_nav_menu` argument to verify that that is the problem. If it is you'd have to write code into the walker so that it uses those classes.
There is also a filter called `nav_menu_css_class` which I believe is what one would use to remove those classes. However, there are numerous other filters in `nav-menu-template.php` and `nav-menu.php` that could potentially be involved. | stackexchange-wordpress | {

WYSIWYG with HTML source?
I'm trying to switch from Drupal to WordPress, and I have lots of articles written in Drupal's WYSIWYG Editors, and stored like
<p>Hi, this is an article</p><p><img bla='bla'></img></p>
So I want to directly copy the source code and paste it into WordPress. I can do it by disabling the visual text editor. So it works for migrating existing articles in.

Featured Images for Tags?
Is it possible to somehow create featured images for tags or custom taxonomies.
For the sake of explanation, I will give an example of the possible functionality.
Say I am running a website that posts the best restaurants by city. Some of my tags could be London, Paris NYC, etc... I have a page that grabs these tags and sorts them alphabetically. But rather than just have text, it would have the tag name (London for example) and an image for that city.
I know this could be done manually, but by attaching an image to the tag or custom taxonomy, it could make the process a bit easier, especially if dealing with a great number of tags/custom taxonomies.

Dynamic sidebar based on category
I am new to wordpress, i have developed a basic theme to make a tutorial web site, for that i need a dynamic sidebar based on category,
suppose, i have category A & B, if user is on the A category i need to display A sidebar, if it's in B category need to display B sidebar,
The sidebar will hold the menu items.
for Demo website see: < click on the any manu and see the sidebar.
i have searched plugin to achieve the stuff, but can't find it. if there is any plugin please suggest, | There are many solutions to your problem, I guess. Two solutions I would recommend are:
## 1\. Register multiple sidebars.
Register more sidebars and then include them conditionally in page templates. So if you need different sidebar for each category (let's say you have 2 categories), then register 2 more sidebars (sidebar-cat-1, sidebar-cat-2) and then replace generic sidebar with one of these two, based on what category is displayed.
## 2\. There is plugin for that ;)

Location of core code for database connection and get_header
I understand WP well enough to create a custom theme at a basic level, but have no experience with the core code. I've also just finished a book on basic php and mysql coding.
I'd like to look 'under the hood' of WP to try and put those together. Can someone tell me:
* Where to find the files that code for the WP-Mysql connection? (as in, `mysqli_connect` ...)
* Where to find the files that code for the `get_header()` function? (which I assume will have something like `include(header.php)` )
Thanks! | First off, the usual caveat -- _Don't modify core code_. (Certainly not on a production site.)
If you read the documentation on the Codex, you'll notice that most if not all of the pages in, say, the Function Reference have a section called **Source File**. Clicking the link located there will take you to the file in trac where the particular function lives.
For instance, the Codex page for `the_ID()` points you to `wp-includes/post-template.php`.
Your specific questions:
* The `$wpdb()` class is in `wp-includes/wp-db.php`.
* `get_header()` is in `wp-includes/general-template.php`.
Sometimes, though, you'll have to hunt all over the WordPress codebase to follow the track of _how does this work?_ You'll find that functions call other functions, which call other functions, which apply filters, and so forth. There's a lot of digging, sometimes, to understand how something in WordPress actually works. Do it. It's worth it. | stackexchange-wordpress | {

Close a wordpress blog - keep site as it is but prevent hacks
Last summer I created a travelling-blog on my webspace to document my journey. Now the journey is over and I won't put any new posts in this blog. I also don't whish to have any new comments.
How can I close the blog (to make in invulnerable to external hacks, even if I don't install any new upgrades) but keep all posts, comments, pictures, etc. as they are?
What I found is
* < (however, although the resulting static page contains all the blogged content, the design is really messed up.)
* < (I couldn't try this one, because it is written in python and I don't know any python.)
~~Is one of them recommendable?~~
Is there another way to prevent all interactions with the page, so there's no need to take care about wordpress (or plugin) updates, while still keeping the site secure? | Why not just disable comments and registration?

Wordpress: Apply filter/hook to a particular sidebar widgets?
I'm developing a theme that has more than 5 different sidebars and I want to apply a function to a particular one of them for styling purposes. Basically, the function will modify it's params using a counter to show random 's between each of the widgets. I came up with that:

// ...
}
add_filter( 'dynamic_sidebar_params', 'widget_params' );

How to grab a specific page of content from paginated post?
In my case I've got to create articles where each article has a custom, unchanging "header" part far too rich for the title and the excerpt (it's to contain image, media etc), and then a few different pages of content. I've decided to do this using `<!--nextpage-->` to keep it lightweight and easy for whoever will create the pages - treat the first page as the unchanging header and attach page 2, 3, 4 under a fixed set of links - an custom menu generated in that category, replacing standard pagination "Page 1 2 3 4" links.
In order to do that, I'll have to call `the_content()` twice; once for page 1, and once for whichever page is chosen through the dedicated menu. Except I have no clue how to make `the_content()` extract _n_ -th page, other than through appending / _n_ / to the URL.
Is there some variable, function, plugin, modification to the code that lets me extract a specific page of paginated post? | `nextpage` pagination is a bit odd. You will have to parse the post content. This should do it.
function get_nth_page($n=0,$content='') {

$pages = explode('<!--nextpage-->', $content);

return $pages[$n];

Get post type from taxonomy or category page
This might be somewhat backward, but how can one get the post type being displayed on an archive page?

Use wordpress functions in another PHP file
I have created in my theme folder a PHP file named gallery.php. In this file I want to use WP_Query function, but I can't do this because it shows error.

Thanks in advance! | You must put your `gallery.php` in the same theme folder, where the theme's `functions.php` resides. Then add a single line in `functions.php`:
get_template_part('gallery','');
It'll include the `gallery.php` file into `functions.php` and `gallery.php` will behave like `functions.php`.
So, you have to keep in mind that, `functions.php` file is a file for WordPress and PHP functions. So anything out-of-format without proper formatting may occur error into the whole site - and `functions.php` is a core file of any theme.

I recently downloaded the WP Mobile Detect plugin and integrated it to my theme (the original mobile detect library I include from the theme folder and the matching WP-functions I pasted directly into `functions.php`).
Now I have one Social Share Plug-In I only want to appear when the site gets requested by desktop devices. So I tried modifying the core files of that plugin, wrapping the output function inside a condition of WP Mobile Detect, like:
if ( ! wpmd_is_phone() ) { // output my share buttons }
Unfortunately, this will return a `Call to undefined function`. How can I fix this? | You either have to include/require the WPMD file that includes the function(s) you are using, or just use the globally defined `$detect` object, like so:
global $detect;
if (! $detect->isMobile() || $detect->isTablet()) {
// output your share buttons
}
**// EDIT**
The above conditional is the equivalent of your `! wpmd_is_phone()` conditional. However, if you want to restrict this to desktop devices only, you should use the following:
global $detect;
if (! ($detect->isMobile() || $detect->isTablet())) {
// output your share buttons

How to create a word press user with hashedpassword
I have set of user data from another wordpress site and i want o create users for each of them in a another wordpress web site..,it is works fine with `wp_insert_user($user)` but problem is the password is hashed agin..,so i can't log with that login information,so how can i create user with hash password or stop creating hashed password | You would have to update the password column in the database (see below). But this alone won't work. Password hashes are salted using the SALT keys in your `wp-config.php` (this must be kept secret). Your new site would **need to have identical keys** for the password verification to work.
The following function updates a given user's password field (in the database) with the provided (hashed) password:
/**
* @param int $user_id The user ID
* @param string $hashed_password The hashed password
* @return int The number of rows updated (should be 1 or 0 ).

Edit custom HTML page from WP admin dashboard

is there a simple way to list every templates / php files used to generate a specific page?

For example i' like to find out how my menu is generated so i can add some conditions to it , and also change the display. Is there a way to find out all the files loaded ? which header is used ...etc... maybe put a bit of code somewhere in the autoload sytem? or using firebug? | WordPress does not really track what theme files are loaded beyond some basic things (for example `$template` global holds main template file).
You can use PHP's native `get_included_files()` to list _all_ PHP source files loaded during request and narrow it down to your theme. Note that for more complex themes this will have not only templates, but likely a lot of framework files as well. | stackexchange-wordpress | {

Xml output not places where i want

Call custom post type by category
Ok, I used Custom Post Types Ui to create several custom post types. When setting up the CPT's I checked off that categories were enabled, and then I added a few categories to one of the CPT's.

Any help would be appreciated. I looked around some, but didn't quite understand the difference between Categories and Taxonomies. If anyone wants to shed some light on that for me, that would be great as well.
Thanks, Matt | Most likely, your Custom Post Types are using custom taxonomies that happen to be named "Category". Try something like this:
$args = array(
'post_type' => $cpt,
'tax_query' => array(
array(
'taxonomy' => '[whatever your taxonomy is named],
'field' => 'slug',
'terms' => 'upcoming-meetings',
)
)
);
$query = new WP_Query( $args );
You may be able to find out the taxonomy name from a management screen in the backend. I'm not familiar with the Custom Post Types UI plugin, so unfortunately I can't really help you there.
### Definition
"Taxonomy" is a catch-all term that encompasses WordPress's native Categories, Tags, and any custom taxonomies that you (or a plugin) may create. So "Category" is a type of taxonomy, as is "Tags".

Passing dynamic options from backend to frontend
I have created an admin options page (using the Redux Theme Framework), in which the admin can customize the website's appearance (text color, background color, background repeat options, etc.. ).
Let's suppose i want to give my user the possibility of setting a custom background for a section. Admin-side, i have a media uploader form (unique id: my_div_background_url).
In the frontend, I can retrieve this option and then echo it like this:
<?php
$options = get_option('my_theme');
$section_background_url = $options['div_background_url'];
echo '<section style="background-image: url(\'' . $section_background_url . '\');"></section>';
?>
My question is: is this the right and best way to do this? Wouldn't it be better if all of my options were saved in a css file whenever the admin changes them, and then having this file included in my website? Or are there others methods? | By default, options are auto-loaded. So all options with `autoload: yes` will be fetched very early. Your option will not need an additional query.
Also, database access is often faster and more reliable than file access. The options table is also usually included in database backups, and it can be exported in multiple formats. So stick with options.
What you should do: escape the URL. It might have been compromised, so …
if ( ! empty ( $options['div_background_url'] )
{
$section_background_url = esc_url( $options['div_background_url'] );
echo "<section style='background-image: url($section_background_url);'></section>";
}

Custom colors for post rows based on post meta value
I'm trying to have the post background colors change depending on a meta value for the specific post type rather than using the post status. Looked everywhere and can't find a solution. (perhaps there isn't one?)
**Specifying post colors based on post-status is simple enough**
add_action('admin_footer','posts_status_color');
function posts_status_color(){
?>
<style>
.status-draft{background: #FFFF98 !important;}
.status-pending{background: #FFFF98 !important;}
.post-*id here*{background: #FFFF98 !important;}
.status-publish{/* no background keep wp alternating colors */}
</style>
<?php
}
**How do I specify the colors based on a custom meta key/value from the post?** | If your theme uses wp post class
function post_classes($classes) {
global $post;
$customMetaVariable = get_post_meta( $post->ID, 'customMetaName', true );
if($customMetaVariable == 'desiredCustomMetaValue'){
$classes[] = 'cssClassName';
return $classes;
}
}
add_filter('post_class', 'post_classes');
then in your style.css you could use:
.cssClassName{
background-color: red;
}
hence applying that class to all of the posts that contain your desired meta value.
if your theme doesn't use wp post class you have to edit the theme to include
<?php post_class(); ?>
ex:
<div id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
//post stuff hurr

Security and Must Use Plugins
From the codex article on Must Use Plugins:
> Can be enabled simply by uploading file to the mu-plugins directory, without having to log-in
This feels like a potential security problem to me. Regular plugins have to be activated via the admin panel before any code from the plugin runs on the site. I always thought this was a sensible security precaution because an attacker who was somehow able to upload a file to the plugins folder would also have to access and modify the database before he could get the code to run. The `mu-plugins` folder seems to provide a simple way to circumvent that.
I know the WordPress devs know a bit more about security than I do, so I was just wonder if someone could explain why this isn't a security hole. | I agree with Wyck's comment. If I can upload files, game over. If I couldn't upload to `mu-plugins` chances are that I could upload, and overwrite, the theme's `functions.php` or Core files instead. Any of those options work as well or better than a `mu-plugin` file would.
The "also modify the database" part is irrelevant because if I can upload files modifying the database is trivial. Just run `wp_insert_user` or use `$wpdb` to run SQL to directly alter the database.
In other words, if I can upload files to the server I have already got more substantial control over the server than PHP is able to deal with, more control than PHP is able to put up a barrier against. The ability to upload to the server is a very substantial hack.
I don't know that activating plugins is so much security as it is convenience. The user can switch plugins on and off, and the developer can use activation and deactivation hooks to run special purpose code. | stackexchange-wordpress | {

Gallery stripped from excerpt of post
I'm having trouble with galleries being stripped/filtered out of the content of the post excerpts before the "read more" click (the galleries load just fine when you click and read the post all by itself on a full page).
Something in the template is stripping that out (there are lots of filters in the theme options, none of which have worked turning them off).
Does anyone know what code to look for that might be stripping something like the standard wordpress galleries? I'm somewhat new to Wordpress and not great at php, so wondering if anyone knew what I should look for.
Side notes: Other templates display it correctly, other gallery plugins do the same thing, there is an extra file content_gallery.php, I don't see any "filters" besides using functions to strip. | Your theme most likely uses `the_excerpt()` function. This function takes the post content and removes all formatting and shortcodes (including the `[gallery]` shortcode), and truncates it to a certain amount of characters.
What you could try is removing this function, and replacing it with `the_content()`, which still respects the `<!-- more -->` tag in posts, but correctly displays shortcodes and HTML formatting. | stackexchange-wordpress | {
