How can I implement a simple post editor?
I want a simple post editor for WordPress, it should be something like tumblr editor or the stackoverflow editor.
My questions:
1. Is there any plugin I can use? (I just can't find it)
2. If no plugin, how can I implement it? Is there any example?
(I saw one site has such editor using WordPress, but they have reworked their site now) | You can use the Stackexchange Editor with the WP-Markdown Plugin, created by Steve Harris in this Question. | stackexchange-wordpress | {

custom walker to add iconfont to wp_nav_menu
I want to add the font awesome iconfont to my menu list items, so I need to make a custom Walker.
Because the font per menu item will be different I was hoping to use the css class in the WP backend to add the name of the icon and then output that css class within the output of the walker.
Example how it should become:
$item_output .= '<a'. $attributes .'><i class="icon-' . [output css class WP backend] . '"></i>';
Does anyone know how to filter the CSS class to be able to add it to the custom walker?
Thanks and Merry Xmas! | ok, I figured it out myself.
instead of using the CSS class (as I cannot figure out how to filter it), I decided to use the description instead.
under the lines with `$attributes` I have added this line:
$description = ! empty( $item->description ) ? esc_attr( $item->description ) : '';
And then I added that to the output as:
$item_output .= '<a'. $attributes .'><i class="icon-' . $description . '"></i>';
I would still be interested to hear whether it can be done with class too? | stackexchange-wordpress | {

Nonces can be reused multiple times? Bug / Security issue?
I've read that nonces are meant to be for one time use only, and after an ajax request, you should issue a new nonce so with the next ajax request, a new nonce would be sent to the server.
However, I just tested repeated ajax requests using the same nonce token, and for each request `wp_verify_nonce` returned true on the same token, meaning it could be reused dozens of times.
Is this intentional, or a bug?
Do I still need to issue new nonces with each ajax request, or can the same one continue to work for all future requests? | In WordPress, nonces are specific to the user, the action being performed, and the time. With regards to time, a nonce is valid for 24 hours, and changes every 12 hours. This is considered an acceptable trade-off, since using a real number-used-once would involve adding a tracking system and having storage of the used nonces.
Nonces are also hashed, and so the NONCE_SALT constant will be part of the resulting nonce as well. Changing the NONCE_SALT will invalidate all nonces immediately.
You should issue a new nonce every time. This is so that if the timing or methodology needs to be adjusted in the future, then your code will continue to handle it appropriately. | stackexchange-wordpress | {

Is it possible to bold certain words in a post title?
I guess I would like to be able to include HTML tags within the title so that when the title is listed certain words are bolded.
Is this possible? When I try to put HTML into the title, the tag itself is output (escaped) in the final page list. | Yes, you can use HTML elements in post titles by default. If your output is escaped a plugin or theme might have touched that. Disable all plugins and switch to TwentyEleven. This will help you to identify the source.
Note that markup is stripped in some places where it is not allowed: `title` attributes and elements, feed markup, nav menus. You should not break that.
Also make sure your markup is valid and allowed for your user role. The `kses` filter will try to remove it otherwise. | stackexchange-wordpress | {

IP address character limit

Turn off ms-files.php after network setup
I have a multisite that was set up on WordPress 3.4. That means that uploads for sub-sites are stored in `wp-content/blogs.dir/{blog_id}/files` and are served through ms-files.php.
In WordPress 3.5, ms-files.php was disbanded completely for new installs and uploads are stored and accessed at `wp-content/uploads/sites/{blog_id}`.
Is there anyway I can switch my install from the pre-3.5 way of serving/uploading files to the new way? I would like to continue serving uploads through `files/` for current blogs, if possible. | In theory:
1. Move images from blogs.dir/SITENUM/files/ to /uploads/SITENUM/ (or make an alias)
2. Edit all sites so they don't look in /files/ but in /uploads/SITENUM/
3. .htaccess, remove the ms-files.php line
4. Search/replace each posts table for each site, changing /files/ to /uploads/SITENUM/
A walk-through can be found here (dumping ms-files), this is not a trivial hack! It involves command-line usage, sql, and using a mu-plugin.

Can I leave off plugin textdomain for terms used in core?
I've got a plugin that puts post statuses into post type admin menus. I'm in the middle of internationalizing it, and I'm wondering how to handle this situation.
The plugin uses some unique strings that will get a textdomain like this:
__( 'Select the post statuses to <strong>exclude</strong> from post type admin menus', 'csmpmsi' )
But then there are also cases where I'm using a core-related word for their core-related meaning like this: `__( 'Pages' )`. In this situation, it seems to make perfect sense for me to exclude the textdomain and take advantage of terms that are already localized in core. However, the codex seems very explicit:
> If you're trying to translate a plugin, the same advice as above applies, except that
>
> * you must use a domain, which is loaded in a hook of your plugin
>
> * every translation call must become __('text', 'domain-name')
>
>
So is this WP-kosher? | Never rely on core strings for translation, they may change or get a `context` parameter any time. Once that happens your users get a partially translated interface, and your translators have no way to fix that.
Also keep in mind the same string is not necessary translated everywhere with the same word. Even without a context parameter it might be useful to use a different translation for your plugin in some languages. But this wouldn’t be possible if you don’t include the string in your plugin.

WordPress settings API error when checkbox unchecked

How to get the ID of the currently logged in user?
I want to get the ID of the currently logged in user. I've found the function: `get_current_user_id` which seems to be working, however I'm not sure what 'current' means in this context.
Meaning if the user views the profile of another user, then will the current user change to become the other user?
In short I'm looking for a reliable way to always get only the id of the logged in user. | `get_current_user_id()` effectively does what @Giri had described in the first snippet. The internal Wordpress function-call chain eventually calls `get_currentuserinfo()` which already checks if there is a WP_User object, meaning a user is logged in.
Thus, from what I can see in the linked code, `get_current_user_id()` always returns the ID of the user that is logged in or zero `0`.
In the current default theme `twentytwelve` they are using `get_the_author_meta()` to retrieve information about the user, for whom the current author page is displayed. So the difference in WP terminology seems to be "user" for th current, logged in user and "author" for some user, identified by an ID. See: twentytwelve/author.php. | stackexchange-wordpress | {

Job of meta_key meta_value fields in database tables

I did read the Database Description in the Codex, but still don't get it. | Think of them as array key/value pairs (kinda). These tables are used to store additional data about particular posts, comments, or users.

As far as **_structure_** goes, that is about it. These are "extra info" tables. You can even add to them via the backend. `*_postmeta` is where the custom fields are stored.
WordPress stores, and plugins and themes can store, a wide variety or information there.

Taxonomies for Wordpress Media Library

I know this has been a long debated issue with WP, but I was hoping that since the 3.5 upgrade, there has been some progress in categorizing images in the Media Library.
Really, what I am hoping to accomplish is creating a set of categories for the images in the Media Library, and then assigning the current images, or future images, to those categories.

wp_list_pages();

function append_list_pages($content) {
return $content.wp_list_pages(array('echo'=>false));

I'm not sure what you mean by that and how deep a division you need in your project. To display the three sections, you could use `wp_list_pages()` three times, and use the `child_of` parameter to pick the right section. Or you could have three menus in the backend, and call each of them using `wp_nav_menu()`. | stackexchange-wordpress | {

How to allow visitors to filter posts by multiple taxonomies
I am trying to allow users to filter a custom post type list by multiple taxonomies. For Example lets say my custom post type is **clothing** and it has two custom taxonomies **brand** and **type** associated with it.
I would like a visitor to first see all clothing posts, then they could click on a brand link that brings them to a listing of all clothing in that brand(I can do this part). From that list of clothing in the chosen brand, I'd like them to be able to further narrow down the list to a type of clothing such as pants, so that now they are seeing a list of pants made by the brand they previously chose.
I've looked around, and I found an older post showing how to do this by creating some rewrite rules: but, I'm really hoping there's an easier way than using rewrite rules out there now.
Can anyone point me in the right direction here? | Alright well this might not be ideal, but it works and was much simpler than I thought!
I ended up just adding a $_GET parameter to the 2nd taxonomy terms' linked url, so I could get the 2nd term from the other taxonomy on the next page through $_GET.
On the next template I built a new WP_Query that uses the tax_query parameters to return posts from both taxonomy' terms, if the 2nd taxonomies term is set.
Any thoughts on a better approach are still very much welcome.

Archive page showing wrong month
My site's archive page is echoing wrong Month name. Though the URL is `2012/11/`, it's echoing the month `December 2012`.
I found nothing wrong with the code:
<?php
if ( is_day() ) :
printf( __( 'Daywise Posts: %s', 'theme-name' ), '<span id="font">' . "<b><i>". get_the_date() . "</b></i>" . '</span>' );
elseif ( is_month() ) :
printf( __( 'Month-wise Posts: %s', 'theme-name' ), '<span id="font">' . "<b><i>". get_the_date( _x( 'F Y', 'monthly archives date format', 'theme-name' ) ) . "</b></i>". '</span>' );
elseif ( is_year() ) :
printf( __( 'Year-wise Posts: %s', 'theme-name' ), '<span id="font">' . "<b><i>" . get_the_date( _x( 'Y', 'yearly archives date format', 'theme-name' ) ) . "</b></i>". '</span>' );

_e( 'Archives', 'theme-name' );

Add code just after Post content
I am in a bit of dilemma here so bare with me. I want to add something like this code just after the content in a post:
<p>Please let me know what you think by <a href="#comment">leaving a comment</a>!</p>
To do this, I edited `single.php` and added it after the content. However, the problem is that many of my posts are separated in several pages by using `<!--nextpage-->` and the above code is displayed on **every page**. I want that line to be displayed only at the final page if the post is separated. How is such thing possible? | There are some global variables available (or not) to detect the current page number:
if ( empty ( $GLOBALS['multipage'] ) or $GLOBALS['numpages'] === $GLOBALS['page'] )
echo '<a id="lastPageLink" href="#comment">comment</a>';
The best way to understand what they do is a look at the internals of `wp_link_pages()`.
* `(bool) $GLOBALS['multipage']` is `TRUE` if there is more than one page.
* `(int) $GLOBALS['numpages']` is the amount of available pages.
* `(int) $GLOBALS['page']` is the number of the current page.
In JavaScript you can add an `onclick` handler like this now:
document.getElementById("lastPageLink").onclick = function() {
window.location.hash = 'comment';
document.getElementById('comment').focus();
return false;

How do I use the WP image functions in a page template?
Wordpress has tons of mature code for image editing on the admin side, but I would like to provide a form inside of a custom page template for my visitors to drag and drop, crop and save a thumbnail image as part of a new draft post. I can do the page template, form, and draft post part, but am getting pretty frustrated trying to integrate the plupload, jcrop and gd library parts. I can do bits and pieces using each of those libraries but can't get them to play nice and it's getting way too complicated for me.
Then it hit me: WordPress can do all that magic stuff on the admin side already (having "bundled" those common libraries), so if I can leverage those wp core functions from the front-end, I will be done. Can anyone give me an example or two on how to use those wp core media functions from inside a user-facing page template?
Please see my similar post on wp.org | The two key things I was missing was the realization that those javascript libs must be literally enqueued on the user-facing page that I intend to use them, and just experience on the mechanics of sending data between javascript and php by means of ajax and json. | stackexchange-wordpress | {

Installed WordPress with Softaculous. Should I upgradeManually or with Softaculous?

The roles have the `unfiltered_html` capability that allows them to put whatever HTML they choose, including `<script>` tags, where ever they choose.
Is is a security risk? Only if you give folks you don't trust admin and/or editor roles. Or someone gains access to your an admin/editor account. Or there's another security hole somewhere in the core that allows privilege escalation from a lower to higher user level (unlikely).

Disable WooCommerce action
I'm customizing a WooCommerce theme and am going to be moving the title. There is an action in `content-single-product.php` called:
do_action( 'woocommerce_single_product_summary' );
in the `woocommerce_hooks.php` file the title action is:
add_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_title', 5 );
I can easily comment this out and place the title function where I need to. I'd prefer to disable the title using a function in my themes `functions.php` file so I don't have to worry about modifying core files. What would the function be to disable this title action? | That would be:
remove_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_title', 5 );

Organize template parts and page templates in folders in regards of template hierarchy
Hello and happy new year
Suppose one has a large theme composed of several post types, page templates and a bunch of custom loops and template parts which is best keeping in separate php files. What's the best practice to organise these files?
For example, suppose I have 10 page templates. How about putting them in a folder named "pages"? And another folder for the archives?
However, how to let Wordpress know where to look for the templates?
Thanks | Page templates are special case and since WP 3.4 can be put in subfolder natively. Other than that WP mostly expects flat file structure for templates.
While template hierarchy is easily adjusted (see dynamic filter in `get_query_template()`, pretty much only thing needed)... From personal experience - overly extensive and nested directory structure for templates makes developer workflow overly unpleasant very fast.
If you have extreme quantity of templates "how to reduce amount?" is better question than "how to stuff them into folders?". | stackexchange-wordpress | {

Retrieve the template directory URI via global or get_template_directory_uri() every time?
One Wordpress function I happen to use frequently is `get_template_directory_uri()`. While I tried to minimize or avoid its use where I can, I still happen to have more than one call to this function in certain pages across my theme. Most of the time in a series of href or inside other functions (for which I normally put the URI resulting from `get_template_directory_uri()` in a `$variable` \- however I still find that I might have to store again that variable in a different php file).
I wonder, would it be best if I store the returning value (my theme URI) in a global and use echo the global when I need it in different parts of my theme php files?
I'm still learning my way to best practices and uses of variables and globals.
Thank you | I would stay stick to the function. PHP caches functions for speed and efficiency. In some situations, using a function is _faster_ then using a variable.
There are other benefits too - imagine if you changed the name of your variable - you would have to go and update every piece of code where it's used. | stackexchange-wordpress | {

How to use add_settings_error in register_setting callback

I can not understand why the error does not exceed, any suggestions? | Take a look at the `add_settings_error` prototype.
add_settings_error( $setting, $code, $message, $type );
The first argument is your settings name/key -- or if your setting is on another page (eg `general`) it should be the page key. The second is whatever you'd like to add to the ID attribute, then error/updated message, and finally type. It doesn't work because you're using it incorrectly.
So you probably want...
<?php
add_settings_error(
'your_setting_key', // whatever you registered in `register_setting
'a_code_here', // doesn't really mater
__('This is the message itself', 'wpse'),
'error', // error or notice works to make things pretty
);

What are the advantages and disadvantages of Option Tree over the Customization API?
I'm relatively new to WordPress theme development, and I had to create a theme with options available. I did a Google search to see what are the possibilities, and I read articles about such, and read about frameworks, and I came across Option Tree, which was recommended as a framework to develop with.
What my question is, when I'm developing themes to sell, what are the advantages and disadvantages of Option Tree over the Customization API built into WordPress? | disadvantage using option tree:
1. Your theme depend on other work as a core
2. You need to always keep an eye for the plugin update ( which is really not good if you're going to use it in premium theme )
3. If you're going to integrate it in your theme, then when there is update from the plugin you will need to do lot of things to update it in your theme.
advantage :
1. Save you the time to create your own theme options
If you have lots of time I suggest you to create your own theme options which will be better if you're gonna use it in a premium theme to sell, you'll have more control over the theme options.
And if you're not going to write your own script, I suggest you to use Options Framework Theme which is specially build to include in theme rather than using plugin. The author is keep updating the script itself so its safe to use it, I also use it in my premium theme. | stackexchange-wordpress | {

Until now I was taking a manual backup of my wordpress page. I tar'ed the /var/www/website files to a tar, and mysqldump of the database to a sql file. And when I need to restore, I do a search replace in the sql file all localhost to that dns (where I am restoring) and untar the tar file to /var/www/website of my new host.
But with ColorWay theme, all my settings are lost. I wonder where else will a theme store all its data ? Am I missing something basic here ?
Infact any theme, I loose some setting or the other. Sometimes the menu choice, sometimes a few other settings. | > And when I need to restore, I do a search replace in the sql file all localhost to that dns...
Doing a find/replace in a text dump of the database will break the serialized data stored in theme options.
Use interconnectit.com WordPress Serialized PHP Search Replace Tool to correctly find/replace serialized data. Some simple themes without options don't serialize data, and a find/replace in a text dump is OK; but many themes will break. | stackexchange-wordpress | {

post_class remove tag- or category- from slug
I've got this in my theme
<article <?php post_class('archiveMain'); ?>>
But for tags and categories it adds tag- or category- before the slug, any way to remove that?
Example: tag-sales would just be sales, category-webinar, just webinar | You can filter `post_class` and change these class names:
add_filter( 'post_class', 'wpse_78237_post_class' );

foreach ( $classes as $class )
{

}

{
$out[] = substr( $class, 9 );
}
else
{
$out[] = $class;
}
}
return array_unique( $out );
}
But be aware this could result in collisions with other class names, in `body_class` for example. I would not do that. | stackexchange-wordpress | {

Force user to login in home page
I have a custom login form working properly on my home view. Nice. But what I want is when user try to view some page, be redirected to my home view instead of wp-login. Im trying to do this way:
add_action('template_redirect', 'redirect_to_login');
function redirect_to_login(){
if(!is_user_logged_in()){
wp_redirect(home_url()); exit;
}
}
It's not working. Browser says it has too many redirects. What can I do?
Thanks! | `template_redirect` is called on every page load including the home page so your code will redirect the user to the homepage even when user is visiting the homepage
You could add another condition there, `is_home()` or `is_front_page()`, depending on the setting in admin, but i recommend a longer approach for better compatibility
a) Hook into `login_url` to change the url for login. This tells wordpress that login form is present on homepage & `wp-login.php` should not be used
add_filter('login_url', 'change_login_url');
function change_login_url() {
return home_url('/');
}
b) Use `auth_redirect()` which makes sure user is redirected back to the previous page
c) Use `wp` hook and not `init` since the conditional is_front_page() will not work as $wp_query global has not been set yet.
add_action('wp', 'force_user_login');
function force_user_login() {
if(!is_user_logged_in())
auth_redirect();

Wordpress display image link in shortcode
I have a shortcode that display an image when you use the image url inside it.
function image_code($atts, $content = null) {
return '<img src="'.$content.'" class="user-imgs"/>';
}
add_shortcode('img', 'image_code');
So when I use the code like this:
[img]
it display only the image like this:(in the css I have set the .user-imgs to max-width 600px)
<img src="
But I want to display a link to the full image, like this:
<a href=" src="
How I can retrieve the image url used in shortcode and use it as a link in to the original image? | You can reuse the `$content` parameter:
function image_code($atts, $content = null) {
$url = esc_url( $content );
return "<a href='$url'><img src='$url' class='user-imgs' /></a>";
}
Or pass the URL as parameter in case you want to use a different URL:
function image_code($atts, $content = null) {
$args = shortcode_atts( array( 'url' => FALSE ), $atts );
$img = esc_url( $content );
$url = $args['url'] ? esc_url( $args['url'] ) : $img;

Override pluggable functions in a plugin?
WordPress has a file called `pluggable.php` which contains a list of functions you can override in your plugin.
The problem I am facing (I am overriding `wp_authenticate`) is for each blog in my network I try to activate this plugin, I get:
> failure, can't re-declare wp_authenticate which was previously declared in pluggable.php
This somewhat defeats the ease of use, I have to comment the function in the plugin file, activate the plugin, un-comment the function for it to work properly.
What is the correct way to do it?
Can't expect users who download plugin to do all that.
I am using 3.5 + multi-site configuration | Wrap your function in `if( ! function_exists( 'wp_authenticate' ) )` to get rid of the error and successfully activate your plugin:
if( ! function_exists( 'wp_authenticate' ) ){
function wp_authenticate(){}
}
This is necessary because in the context of activating a plugin, the function _does_ already exist, only after it is activated will your plugin load first and override the original in `pluggable.php`. Plugins are activated in a sandbox to capture any fatal errors which may prevent activation and successful recovery to a working state. | stackexchange-wordpress | {

How can I attach hotlinked images in posts/pages within the same server?
Not sure if this makes sense but I'm trying to attach hotlinked images to their posts/pages with no lucky, most plugins such Cache images works ok but only to external domains, I need to auto-attach hotlinked images in the same domain/server.
_Addendum_ : This happened duo copying-pasting content from static html files into WP pages and posts.
Thanks for any clue! | Thanks @toscho, I think I figured how your code can work (that can take time hahah), firstly import images files within server (Add form server plugin can do this or can use a custom script), find image paths within every post/page that match filenames now in media library, then attach them.
I can't use this because there where different imagens but same filenames along different folders (also some problems with filenames using spaces), then I had to use this plugin, you must visit/edit every page/post and download the images, that can be a pain but at least will work with files wherever they are (same doamin for example), surely there is someway to hack this plugin to work on every post on page.
(If image filenames has spaces this plugin still will return empty images and you need to re-edit it manually, don't know why WP can diplay hotlinked images with strange filenames) | stackexchange-wordpress | {

The inner mechanism of WP SEO plugins
This is more of a conceptual question, but it has actual ramifications.
Going through the various SEO plugins I found nowhere a PHP tag that should be embedded in the actual HTML page and echo the meta data. How does it work then?
Simply saving it to the DB doesn't seem enough. What is the mechanism through which the plugin "injects" the SEO data to the page? | In case you are talking about adding meta tags and changing the title they rely on `wp_head` action being fired at theme header before the `</head>`tag is generated.
For changing the title they probably use the `wp_title` filter. Older versions of "all in one seo" used to buffer the head section and replace the title tag in something like
add_action('init','start_buf');
function start_buf( {
ob_start();
}
add_action('wp_head','end_buf');
function end_buf() {
$head = ob_get_contents();
$head = string replace '<title>....</title>' in $head with the configured title

Remove Actions added by SEO ultimate Plugin

//Hook to output all <head> code i changed the priority to 2

add_action('wp_head',array($this, 'remove_seo_header'),1);
}
function remove_seo_header() {
remove_action('wp_head', array($seo_ultimate,'template_head'));

How to change tag Title to its name?
i have previously asked it in stackoverflow, but there was no answer!
I wish to change the title of Tags pages of my wordpress blog. What I want to do is to keep the Tag name as it's title only.
For example: If a tag name is "Wordpress Tag Pages Tutorial" then that tag should have the same title "Wordpress Tag Pages Tutorial" instead of "Blog Name - Wordpress Tag Pages Tutorial" so what to change in this code? I have tried but showing errors like only variables name in wordpress title.
<title>
<?php if (is_home () ) { bloginfo('name'); }elseif ( is_category() ) {
single_cat_title(); echo ' - ' ; bloginfo('name'); }
elseif (is_single() ) { single_post_title();}
elseif (is_page() ) { bloginfo('name'); echo ': '; single_post_title();}
else { wp_title('',true); } ?>
please see this screen-cast i.stack.imgur.com/Ai9JU.png | Use …
if ( is_tax( 'post_tag' ) )
echo single_term_title();

Remove Spaces From WP_LINK_PAGES
By default, wp_link_pages (the code which allows you to breakup posts into multiple pages) creates spaces between each number. Is there a way to remove these spaces via functions.php? | Just replace `a> <a` with `a><a`:
echo str_replace( 'a> <a', 'a><a', wp_link_pages( array ( 'echo' => FALSE ) ) );
If you want to remove the spaces around unlinked numbers too, I suggest a separate function in your theme’s `functions.php` to keep the code readable:
function trimmed_link_pages( $args = array () )
{
$args['echo'] = FALSE;
$links = wp_link_pages( $args );
$links = str_replace(
array ( 'a> ', ' <a', ':<a' ),
array ( 'a>', '<a', ': <a' ),
$links
);
print $links;
}
Use it like `wp_link_pages()`:
if ( have_posts() )
{
while ( have_posts() )
{
the_post();
print '<h2><a href="' . get_permalink() . '">' . get_the_title() . '</a></h2>';
the_content();
trimmed_link_pages();
}

Is Wordpress Suitable for my site?

In addition to just photo/gallery management, payment systems are all handled through 3rd party plugins. So they are fairly cumbersome in themselves.
