Hide content editor for posts after approriate date
I am tuning my new site and i what to disable Content Editor for post created after date X, but for posts that created before that date Content Editor must be on its place. | function disable_editor_for_old_posts_wpse_101106($post) {
if (strtotime('-2 months') > strtotime($post->post_date)) {
remove_post_type_support('post','editor');
}
}
add_action('add_meta_boxes_post', 'disable_editor_for_old_posts_wpse_101106');
I couldn't find a great hook for this but `add_post_meta_boxes_*` is early enough, and it passes the `$post` object to the callback.
Basically the filter checks the post on the post edit screen and removes post type support based on the post age. I used two months as the cutoff but that is easily altered.
I don't see the point of worrying about the editor except on the backend, unless you have a front-end posting mechanism.
Removing the editor makes the page a bit ugly, but I think that adding some kind of message meta box via `edit_form_after_title` would sort that out-- as done here: <

Why do filters/actions require an argument count?
I was just looking at plugin.php trying to answer the above question and I couldn't work it out. The actual code that calls filters is this:
do {
foreach( (array) current($wp_filter[$tag]) as $the_ )
if ( !is_null($the_['function']) ){
$args[1] = $value;
$value = call_user_func_array($the_['function'], array_slice($args, 1, (int) $the_['accepted_args']));
}
} while ( next($wp_filter[$tag]) !== false );
If `(int) $the_['accepted_args']` wasn't there then it would simply pass everything available to the target function without any adverse affects for functions with less formal params. | 1. Because of backwards compatibility.
You can use the same callback for multiple filters. Inside of that callback you should use `current_filter()` to determine the context. But some plugins use the number of passed arguments instead. Changing that would break these plugins.
That’s why you should always use the API (here: `current_filter()`) and not some made-up construct.
2. Also, PHP will raise a warning when you pass more parameters to a native function than that function expects.

How can I change the title of the Home link in the navigation bar?
I use Bones theme with a static front page. The header.php calls the `bones_main_nav()` function without parameters, while `bones_main_nav()` only calls the `wp_nav_menu()` function. | `wp_nav_menu` with no arguments and no menus defined in the back end at `wp-admin->Appearance->Menus` (which sounds like the circumstance you describe) just lists your pages, plus a "Home" link.
That is done by calling `wp_page_menu`, the default callback for `wp_nav_menu`, which means that under those conditions you can alter that text by hooking to `wp_page_menu_args` and setting, or changing, the `show_home` argument.
function alter_default_home_link_wpse_1011444($args) {
$args['show_home'] = 'Home is where the heart is';
return $args;

Wordpress multisite haml templates
I'm building a very large Wordpress multisite at the moment and while I sort out the project at a top level I want to know if it's possible to use haml or phamlp for my templates instead of php.
I have seen two plugins for Wordpress but neither of them seem to work with a multi-site.
My question is, how would I write a VERY basic plugin to read the templates and output them in place of the usual ones?
I want to use haml because it's much cleaner than large html/php templates and I just want to parse header.haml instead of header.php if possible. | Filter `template_include` and use your own templates:

How To Show Get Adjacent Posts If Posts Are Sorted By Custom Field
I want to get the ID of adjacent posts.
For posts sorted chronologically you can use:
get_adjacent_post
Are there any standard methods for finding the adjacent post if the posts are sorted by custom field value. Unless its very simple my skills are not up to writing a new function for this purpose.
Thanks. | Hmmmm, the solution to this problem was to read the details of the plugin. It has the capability of returning values other than a link to the next post - this includes the ID of the Next and Previous Post.
In case anyone else reads this in the future and wants to see how to get the ID all you have to do is something like:
<?php $link=next_post_link_plus( array('order_by' => 'custom', 'meta_key' => 'Sort Number','return'=>'id') );?>

TinyMCE Editor Set Default Tab

Add Previous/Next Buttons to CPT Single Pages Only
I'm working with a site that is displaying a portfolio CPT on the home page in a "Grid Loop." On the single pages, i'd like to add Previous & Next Item buttons. I thus added this code:

<div class="nav_left">
<span class="prev"><?php previous_post_link('%link', 'Previous Item</span>'); ?>

<span class="next"><?php next_post_link('%link', 'Next Item</span>'); ?>
</div>
</div>

}

Secure Pages Best Practice

So, if there is a way to "protect" those pages I would love to know. | Not sure about the best practices, but I have a few custom login-sensitive pages which simply display a message if user is not logged and is trying to view the page directly:

<article id="post">
<?php the_content(); ?>
</article>
<?php
} else {
_e('You are not logged in. Please ', 'abc');

Migrating database / content of non-CMS site to Wordpress
I have a non-CMS website which is fully build with PHP with a lot of content in it. I don't want to add my posts manually in Wordpress, because that's a pain in the ass (I am talking about 5000 posts)...
So my question would be: how do I do this? Is it even possible to clone something like this? | If your data is inside database as I understand, it is possible to export your database to CSV file and import this to Wordpress. CSV file is basically a comma separated list of data from your database that makes it possible to transfer data from different database structure to another.
It does indeed take some effort to configure your export/import so that you get your data right, but it's a lot easier thing to achieve than re-posting 5000 posts.
Look for Wordpress plugins "csv importer" and/or "wp ultimate csv importer".
You can export your data using your SQL-client (these often have an option to export in csv) or using PHP (see <
If your data is NOT in database, you could consider web scraping techniques (see: wikipedia / Web_scraping) where you go through your site programatically and look for id's, classes and elements to create structured data out of your html files.

WooCommerce - Is is possible to replace downloadable file and allow existing customer to get it?
I have a WooWommerce 2.0 shop where I sell downloadables and, from time to time, I have to replace existing files with newer versions.

Thanks in advance for the answers. | Wherever the actual file is, you should be able to FTP to it and simply replace it with a file with the exact same name.

Output Sanitation

Is 'preload="none"' a valid parameter in the [audio] shortcode in WordPress 3.6?
I know that MediaElement.js is part of the WordPress core in WordPress 3.6. I currently use the MediaElement.js plugin on my WordPress 3.5.1 sites. On some pages, we have several players on one page, and we need to specify `preload="none"` as a parameter in the MediaElement.js shortcode, because if we don't, some browsers (mainly iOS devices) will try to download all the MP3 files at once.
Here is the shortcode that we currently use:
[audio mp3="filename.mp3" preload="none"]
In WordPress 3.6, with MediaElement.js built-in, will the `preload="none"` parameter have any effect in the `[audio]` shortcode? | I looked at the wp_audio_shortcode function in wp-includes/media.php of the release version of WordPress 3.6. The _preload_ parameter is a valid attribute of the [audio] shortcode. However, the default is 'none', so in my case it is not needed.
From WordPress 3.6 (release), wp-includes/media.php, function wp_audio_shortcode:
$default_types = wp_get_audio_extensions();

'src' => '',
'loop' => '',

'preload' => 'none'
);
foreach ( $default_types as $type )
$defaults_atts[$type] = '';
$atts = shortcode_atts( $defaults_atts, $attr, 'audio' );

Internal Server Error every time I push up my Wordpress Project to Heroku
We use Heroku to deploy our Wordpress project. However, everytime we push up it seems that all of the links bring the user to an Internal Server Error page. The homepage works.
Updating the permalinks (using the pretty permalinks for %postname%) solves this issue.

?>

WordPress's "Text" Format
When using self-hosted WordPress, you have the option of writing in "Visual" or "Text" mode.
!visual and text tabs in WordPress editor
Assuming there's no plugins installed,
1. Is this "Text" format a well defined standard or pseudo standard? (like markdown, textile, etc.)
2. Is there a single place in a plugin-less `3.5.1` WordPress where this text is converted into HTML?
3. If the answer to number 2 is "No", how is this text converted into html? | Text its just plain text, just as its saved in your db.
Wordpress changes line breaks with paragraphs with the function wpautop, through the filter `the_content` and `the_excerpt`.
If you need to remove the `wpautop` behavior, you can remove the filter by doing this in your theme's functions.php:
remove_filter( 'the_content', 'wpautop' );
remove_filter( 'the_excerpt', 'wpautop' );
And maybe adding your own customized function:
add_filter( 'the_content', 'my_custom_format' );
add_filter( 'the_excerpt', 'my_custom_format' );
function my_custom_format ($text) {
// do something with $text
return $text;

Change path of the page's template
It's possible to create templates for pages with that:
`<?php /* Template Name: Contact */ ?>`

Amazon S3 + Cloudfront with Wordpress
I put together a wordpress site on a heroku free instance and I'm making all images to go to an S3 bucket and a Cloudfront distribution with this plugin . The thing is, it only uploads the images to S3 and serves them with the proper CNAME I set up.
What I want is to serve the wp-content (all my plugins and themes) through S3. I know it's possible because I've read about it, but all tutorials around are explaining the Origin pull and not this configuration. Can anyone tell me more about how can I achieve this? Thank you!! | There is no remotely easy way to accomplish this with "push" strategy, because (unlike attachments) plugins and themes do not really declare their resources to WordPress.
To push those resources you need to enumerate them and keep that information up to date. In pull configurations this happens automagically in actual use. For push configuration you will either have to scan _everything_ for assets and upload _all_ of them, or build some kind of way (automated or manual) to figure out which are actually used.
In a nutshell - currently WP doesn't really manage of extension's assets and has little functionality to work with them. Thus prevalence of pull configurations you see reflected in information around. | stackexchange-wordpress | {

Wordpress ultra slow if I click on posts?
I have 5000 posts on my website, which I have uploaded from a `CSV` file. This all went well and the website is fast on the back-end and frankly on any other page. There is one exception: if I click on a post, it takes 8 to 9 seconds to open a post, which is very disturbing.

FYI: it's a self hosted website, running on a fast server. The website is very fast, except at clicking on a post.

Cancel jQuery 'noConflict' - is it really unsafe?
I use some external plugins (not wordpress plugins), that use '$', and it's very convenient for me to cancel `noConflict` mode, by adding this line
`$=jQuery`
But I guess they invented `noConflict` mode not for nothing.
The question is how much have to worry about it. And is really a problem to use `$=jQuery`? | The problem with the `$` alias is that a number of libraries quite puzzlingly decided to use the _same_ variable as an alias. If two libraries try to use the same variable, one or the other will win and anything dependent on the other one will break.
If you are only using jQuery, and never anything else, it should be fine to use the `$` but you should not ever do that except for a site that you personally maintain. I suspect you will regret it if you ever want to use another library, though. Using that hack in a plugin or a theme would be very bad form.
What you are doing is only marginally easier than this though (from the jQuery.noConflict docs):
(function($) {
$(function() {
// more code using $ as alias to jQuery
});
})(jQuery);
But then I don't know what kind of "plugins but not WordPress Plugins" you are talking about, or whether that is even relevant.

Will multiple BuddyPress groups slow down a site?

**Edit:**
To make the reason for this more clear, the site is a marketplace, where each product can have a different seller. That's why I'm not looking (nor do I care for) a central support system. Each individual seller is responsible for their own support. | You can easily scale a site to have tens or hundreds of thousands of BuddyPress groups.

taxonomy-editorial.php

Thanks in advance | The templates use the _internal name_ of the taxonomy. These will be the same in all languages.

How to load dynamic option with ajax
Basically I'm creating an options page in which the user will click on a button to display a text input field, which will then be populated by the user with a name.
This name will be then saved into the db using ajax (all that's working already). The user will be able to as many names she/he wants.
At the moment, as a feedback to the user, I'm adding a list with the names that were previously saved with jQuery, however I'd like to load the options from the db to check whether the info collected by jQuery is correct.
I've been doing some research and it seems the way to do it is to use `wp_localize_script` which I'm finding it cumbersome to load dynamically created data.
Is using `wp_localize_script` the correct way to do it or should I just make an ajax call as you'd normally do? | I don't know if there is really a right answer to this question, and I don't know what you find cumbersome about `wp_localize_script`, but you should be able to do it either way.
The difference is that with `wp_localize_script` the data is printed to the source of the page, which you wouldn't want if the data were sensitive, and `wp_localize_script` should represent a wee bit less load on the server as it doesn't require a separate connection as AJAX does.
I'd lean towards `wp_localize_script` unless there are compelling reasons to do something else. | stackexchange-wordpress | {

If you saved an `Array` to the `$wpdb->options` table (`add_option` or `update_option`) then `get_option` will return an `Array`. If you saved a string, it will return a string. If you want a string then you are _saving_ the option incorrectly, but you haven't posted the code that saves this value.

Get user_meta values for a user for an array of meta_keys?
I would like to retrieve the `meta_values` for an array of `meta_keys` for a user. Is there a function in WordPress core that offers this functionality? Something that would work like this:
$array_of_keys = array( 'key_1', 'another_key' );
$values = get_user_meta_array( $user_id, $array_of_keys );
And values would maybe be an array like this:
array(
'key_1' => 'some value',
'another_key' => 5,
);
I could easily write a custom function to do this, but I would rather do it 'the WordPress way' if there is one.
Thanks. | `get_user_meta()` with omitted key argument will return all data for the object.

Why does wp_links still exist in the db schema?

add_submenu_page( 'woocommerce', 'My Custom Submenu Page', 'My Custom Submenu Page', 'manage_options', 'my-custom-submenu-page', 'my_custom_submenu_page_callback' );
}
function my_custom_submenu_page_callback() {
echo '<h3>My Custom Submenu Page</h3>';
}
add_action('admin_menu', 'register_my_custom_submenu_page',99);
You need a high(er) priority number to execute it later then the `woocommerce_admin_menu` function, which has 9, and there is `woocommerce_admin_menu_after`, which has 50 - those functionbs are in `woocommerce-admin-init.php`. | stackexchange-wordpress | {

How can I detect if the current post is in this loop?
My featured articles have been built with the following query:
$featured_posts = new WP_Query( array( 'post__not_in' =--> get_option( 'sticky_posts' ),
'meta_key' => is_featured',
'meta_value' => 1
) );

Many thanks. | `$is_featured_post = get_post_meta(get_the_ID(), 'is_featured', TRUE);`
This will return the value in the variable and you can check your condition.

How to remove comment link title attribute?

Choose to Display Post Thumbnail?
I noticed the website < does something cool with images in posts - some posts have a large featured image above the title, others have none and just have images in the content.
My best bet on how to achieve this in WordPress is to add `<?php the_post_thumbnail('large'); ?>` above the title and make a selectable option to display or not display the_post thumbnail in the post edit screen. It would need to only apply to the post (and not the excerpt)... I'm not sure how I would create that option. I would appreciate if anybody knows how this would be done, can direct me to a somewhat relevant tutorial, or has a better idea of how to achieve this. | This is modified code from `twentyten` that does what you're looking for. Put this in `header` or wherever you want the image to run. See string `post-thumbnail` \-- that is size. Make sure it is defined as `940 x 180` in `functions.php`
if ( is_singular() && current_theme_supports( 'post-thumbnails' ) &&
has_post_thumbnail( $post->ID ) &&
($image = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), 'post-thumbnail' ) ) &&

echo get_the_post_thumbnail( $post->ID );
elseif ( get_header_image() ) : ?>

Only Display Thumbnail if Larger Than
Is there a way to only display `<?php the_post_thumbnail( $size, $attr ); ?>` if it is larger/smaller than specified dimensions? | You may be able to make this work with a filter on `post_thumbnail_html`.

How to create a theme specific translation of buddypress?
Originally asked on the BuddyPress forums:
For distribution purposes I would like to include my customized buddypress language files in my theme alongside my other language files. No matter what I try though I can only get the language files to display if I copy them over to `wp-content/languages` as described in the buddypress codex. I thought that the following would work, but it doesn’t:
function load_buddypress_language_files() {
load_theme_textdomain('buddypress', get_template_directory() . '/lang');
}
add_action('plugins_loaded', 'load_buddypress_language_files');
This is possible isn't it?
WP: 3.5.1 BP: 1.7.2 | First, actions added to `plugins_loaded` hook will not work from theme `functions.php` or any theme file because at that point it will be already fired (too late from theme files).
What you can do is to hook your action into `after_setup_theme` and unload `buddypress` text domain first and then add your custom `buddypress` text domain file. The reason is that WordPress will not load any translation files for text domains that has already been added:
add_action('after_setup_theme', 'replace_bp_mofile');
function replace_bp_mofile() {
$mo_file = get_stylesheet_directory() . '/languages/' . sprintf( 'buddypress-%s.mo', get_locale() );

Attachments broken after giving WordPress its own directory
I set up a fresh WordPress installation in a folder called 'wp' under root. I followed the directions for Giving WordPress Its Own Directory and pointed the URL to root successfully.

WP stores the uploaded images in your database. Imported images probably direct to the old root, so you should change that to the new root.

418 header status, I'm a teapot
I'm just backing up a clients via ftp site prior to working on it, when suddenly all urls are returning an error page with the header status being `418`.
A quick Google finds that this was created for an April Fools joke. Does any body have any idea why I would be getting this error? | You were right Toscho, it is a plugin called 'better WP-Security'
I did a search for '418' as suggested in the files I had backed up via ftp and found this:
$bwpsmemlimit = (int) ini_get( 'memory_limit' )
//if they're locked out or banned die
if ( ( $bwpsoptions['id_enabled'] == 1 ||$bwpsoptions['ll_enabled'] == 1 ) && $this->checklock( $current_user->user_login ) ) {

Does Wordpress check for updates of a plugin via plugins root folder name?
I just completed writing a plugin from another plugin. When I changed the developer name, version and other details from the plugin file, I thought the version tracing would now be done using the new name of the plugin but it actually linked the update to the older plugin until I changed the root folder name for the plugin. Wasn't the update supposed to be happen from the details provided in the file? Please guide. Thanks | WordPress uses the 'plug-in slug' to identify a plug-in (and uses this as an 'id' for plug-in updates, though its not clear how, as the code isn't published). The plug-in slug is determined by the location of the `.php` file header containing the comment header necessary for plug-ins. (see source)
So if your main plug-in file is `...wp-content/plugins/pluginA/pluginA.php` your plug-in slug is `pluginA/pluginA.php`, and will by default check for plug-in updates using that slug.
So to give your plug-in a different slug its necessary to change the name of the plug-in file/directory.
Of course its also possible to just prevent your plug-in from checking for updates or change where it looks (e.g. Have WP Theme update from Git Repository). (This is not allowed for repository-hosted plug-ins). | stackexchange-wordpress | {

When to use the Filesystem API? Should I use it at all?
I'm wondering when it is recommended to use the Filesystem API, and whether it's useful at all?
WordPress seems a little inconsistent when it comes to Filesystem API usage, it uses the API only in a few places when uploading and unpacking files, and that doesn't make much sense to me, I mean, where's to point in using it at all when there are a lot of other situations where the PHP filesystem functions are used for direct access? Uploading packages would work even when there are ownership "problems", however I'm pretty sure that these "problems" won't go away 5 minutes later when I'm utilizing any of the functions that are using for example fwrite directly.
So why should I as a plugin/theme developer care about it anyways when half of the WordPress functions I'm using does not rely on the Filesystem API, my plugin/theme wouldn't work correctly anyways, wouldn't it? | There is a bit of practical split about where WP can write files and if `Filesystem API` is invoked. It might be easier to see this divide not as technical, but as administrative.
There is **user** space.
Users _must_ be able to do things like create attachments and _must not_ need to have admin access credentials.
For these requirements uploads directory typically requires lax permissions and code that works with it is usually _not_ using `Filesystem API`.
Rest is **admin** space.
Administrators/developers _must_ be able to (over)write anything (plugins, themes, WP core itself) and _have_ admin credentials.
For such functionality code _is_ using `Filesystem API` and will prompt for credentials, if it can't accomplish task without them.
So rule of a thumb for development distributable code is roughly - uploads directory is _one and only_ place in WP installation where you can expect to perform writes without using `Filesystem API`. | stackexchange-wordpress | {

Can a plugin be run in a different language than WordPress?
I am working with a site that is running WordPress in English, but they would like to run one of their plugins using the Welsh language. We already have the appropriate .po/.mo files for the plugin, but they are not being used while WordPress is running in English. Is there any way, perhaps with some custom PHP code in the plugin, that we can force WordPress to use the Welsh language files just for this plugin, but leave the rest of the site in English? | Assuming the plugin makes use of localization at all, you could for example try exchanging the possible `load_plugin_textdomain` call with `load_textdomain` where you can point to the file you like.
A cleaner way would be using the `plugin_locale` filter that let's you modify the locale used by a plugin:
function my_plugin_locale_filter($locale, $domain)
{
if($domain === 'the_plugins_textdomain')
{
return 'cy_CY';
}
return $locale;
}
add_filter('plugin_locale', 'my_plugin_locale_filter', 10, 2);

How to reduce spam

How to remove certain words from url slug
Trying to create a SEO plugin, that will remove stop words from slugs.
This is how to `explode` the `$slug` into a list, and explode the variable containing the stop words :
add_filter ('sanitize title', 'remove_false_words');
function remove_false_words($slug) {
if (!is_Admin()) return $slug;
$slug = explode ('-', $slug);
foreach ($slug as $key => $word) {
//The $slug has been exploded and retrieves its value
$keys_false = 'a,above,the,also';
$keys = explode (',', $keys_false);
foreach ($keys as $1 => $wordfalse) {
if ($word == $wordfalse) {
unset ($slug[$k]);
}
}
}
return implode ('-', $slug);
}
Is it correct to `unset` the value here? Or should I use a different way of achieving the same result? | There should be no problem with `unset`. There is your answer. What matters with a filter is what you return and `unset`ing those keys before your rebuild the string and return it, works.
You are doing too much processing by `explode`ing your `$keys_false` inside a loop, and you have a typo, and you are better off just making an array instead of creating a string that you convert to an array, and PHP has a function to do what your loop is doing. I reorganized it for you.
function remove_false_words($slug) {
if (!is_admin()) return $slug;
$keys_false = array('a','and','above','the','also');
$slug = explode ('-', $slug);
$slug = array_diff($slug,$keys_false);
return implode ('-', $slug);
}

How to retrieve taxonomy terms of the current custom post?
I have a custom taxonomy _worktype_ and I have 3 types in this latter custom taxonomy: \- creation \- collaboration \- lab
I have also a custom post type "works". _worktype_ is used only for the custom posts type _works_
I have single-works.php as a template and everything is ok
BUT, I need to retrieve the worktype of the current single post. How can I do that ?
(the final idea: build a breadcrumb like that > ; in order to navigate a bit better) | Use `get_the_terms( $post, $taxonomy )`:
$worktypes = get_the_terms( get_the_ID(), 'worktyp' );
var_export( $worktypes );

Do plugin files have to follow a specific convention to be "picked up" by WordPress?
I developed a plugin using the normal convention of naming the main plugin file after the plugin folder (i.e. `prefix-someplugin` for the folder and `prefix-someplugin.php` for the file). However, I saw some plugins that use the following structure:
prefix-someplugin
- plugin-loader.php // This file just loads src/prefix-someplugin.php
- /src
- prefix-someplugin.php
Obviously, if they used such structure, it means that it works. The issue is that I'm not sure **how** it works, hence my question. How does WP know which file to load as the main plugin file? I would have assumed that it looked for a file named after a folder, just adding `.php` as an extension, but it seems I was wrong.
Does WPjust scan `wp-content/plugins` for folders, and loads all the files it finds in them, or does it follow a different logic?
Thanks in advance for the answers. | WordPress detects a file as _plugin_ when there is a plugin header. So you can store multiple plugins in one directory, and they all will be recognized as different plugins.
Each file with at least `/* Plugin Name: something */` is a plugin.
The reason is that WordPress scans all PHP files in the main directory of a plugin.
You can use any name for the plugin file. Avoid non-plugin files in the main directory. They just eat runtime. Put all other PHP files into sub-directories. | stackexchange-wordpress | {

Including files in Child Themes
Twenty Thirteen uses the following in functions.php: `require( get_template_directory() . '/inc/custom-header.php' );`. When I copy /inc/custom-header.php to twentythirteen-child, it isn't replaced. I can't use `require()` because two copies will be included. How this should be handled? | `get_template_directory` looks in the parent theme for files.
> In the case a child theme is being used, the absolute path to the parent theme directory will be returned. Use get_stylesheet_directory() to get the absolute path to the child theme directory.

Including style.css in Child Theme
Twenty Thirteen uses `wp_enqueue_style( 'twentythirteen-style', get_stylesheet_uri() );` in functions.php.
Wheter I use it or not use it in twentythirteen-child/functions.php the style.css from Child Theme is loaded (it is always loaded) and style.css from parent theme can never be loaded.
This is an exception to other files added via `wp_enqueue_style()`, right? It doesn't behave like all the other scripts and style files that are added with `wp_enqueue_script()`.
So, I can't load parent's style.css in the child theme other than via `@import`? | `get_stylesheet_uri` will return the current theme's stylesheet-- the _child_ stylesheet if it is a child theme. While not entirely clear from the Codex entry for that function, it is clear from the entry for `get_stylesheet_directory_uri`, which is used by `get_stylesheet_uri`. What should be happening is that the child stylesheet is being `enqueue`d twice under different slugs.
To get the parent stylesheet you need to enqueue the parent sheet with `get_template_directory_uri`, which always returns the parent. | stackexchange-wordpress | {

Modular CSS and JS in Child Themes
Let's assume that twentythirteen/shortcodes/ exists and inside are folders with shortcodes. 1 folder = 1 shortcode. Each shortcode has: 1 PHP file, 1 CSS file, 1 JS file.
twentythirteen/shortcodes/load.php exists that does `scandir()` and `wp_enqueue_script()` for each JS and CSS file. Furthermore, it has an option to generate twentythirteen/shortcodes/style-cache.css and enqueue only this one (or all JS and CSS files individually).
The structure described above makes it very neat and modular but this will not work with Child Themes? Is there any way to make it work like that? It makes a lot of sense to have 1 folder with 1 CSS file, 1 JS file and 1 PHP file for each shortcode, don't you think? | Putting aside the question of what should and should not be part of a theme, I don't see why something like this wouldn't work with a child theme. Use `get_stylesheet_directory`, which will return the child theme path if it exists and otherwise will return the parent path, to build the path for `scandir` and I don't see the problem. | stackexchange-wordpress | {

Count post + add number =
I'm having problems with counting posts of a custom post type called 'projects' and like to add a number to the count. We did some stuff which can't be shown in our portfolio but would like to add only as number.
Basically it goes as follow:
There are 22 published projects (custom posts type called 'projects') + 11 other projects (no posts) = echo 33 projects.
Edit:
I'm using this to get the wordpress counts:
<?php
$count_posts = wp_count_posts('projects');
$published_posts = $count_posts->publish;
?>
<?php // echo $published_posts ?>
How do I get this working?
Thanks in advance. | If you want to count posts of some custom post type, you can try out the WordPress function `wp_count_posts()`
In your case the custom post type is `'projects'` so you might try this:
$count_projects = wp_count_posts( 'projects' );
$published_projects = $count_projects->publish;
$total = $published_projects + 11; // include your additional projects

Notice: Undefined index: suppress_filters

// Custom Post Type for the public blog posts to show on Index or blog page
add_filter( 'pre_get_posts', 'my_get_posts' );
function my_get_posts( $query ) {
if ( ( is_home() && false == $query->query_vars['suppress_filters'] ) || is_feed() )
$query->set( 'post_type', array( 'news', 'attachment' ) );
return $query;
}
If anyone could help that would be great. Thanks | If `$query->query_vars['suppress_filters']` is not set you will get that message.
Use `empty($query->query_vars['suppress_filters'])` instead of `false == $query->query_vars['suppress_filters'] )` or use `$query->get('suppress_filters')` like this `false == $query->get('suppress_filters')`.

How to oEmbed from custom field, responsive to container size and responsive
I am using Magic Fields 2 to add custom fields/meta boxes.
One custom field is for a Vimeo or YouTube video URL to be displayed.
The following code oEmbeds the video URL:
<?php if (!((get_post_meta($post->ID, 'video_url', TRUE))=='')) {
echo wp_oembed_get( get_post_meta($post->ID, "video_url", true) );
}?>
To resize the video, I have used added the code inside `<div class="video">` and resized it using CSS - `.video iframe {width:500px;height:312px}`.
The problem, this method is not responsive.
I have also tried `.video iframe {width:95%;height:95%}`. This outputs looks like -
!enter image description here
The Fluid Video Embeds plugin seems to do the job for oEmbeds through the normal WordPress method and through shortcode, but not with using a custom field. | I completed the task with fitvids.js by using the plugin FitVids for WordPress.
Chris Coyier describes the integration with WordPress in his screencast Integrating FitVids.js into WordPress (on YouTube).
My custom field name is `video_url`. I used the following code in my template:
<?php if (!((get_post_meta($post->ID, 'video_url', TRUE))=='')) {
echo wp_oembed_get( get_post_meta($post->ID, "video_url", true) );
}?>
In the settings of FitVids for WordPress, simply enter the containing div class or ID which represents the maximum width of the video.

Define constant for one plugin in mu-plugin
I'm trying to define the constant `ACF_Lite` as `true` so that the interface of the Advanced Custom Fields plugin is hidden on all of my multisite subsites except the parent. For clarity and maintainability, I'm wanting to do this from an `mu-plugins` plugin that will also control the fields displayed by that plugin.
I thought this would do it but it didn't:
if( get_current_blog_id() !== 1 )
define( 'ACF_Lite', true );
The plugin author says that this needs to be in `wp-config.php`, but I'm surprised that this doesn't work because, according to the codex, mu-plugins are:
> Loaded by PHP, in alphabetical order, before normal plugins,
I've confirmed that `get_current_blog_id()` returns the right ID, so that's not the problem. I've also tried explicitly hooking that to `muplugins_loaded` and `plugins_loaded` but that has failed.
Can anyone explain why I can't define this from `mu-plugins`? | @toscho's link solved this. PHP constants are case sensitive.

Permalinks is not working in my wordpress setup
I am newbie to wordpress. I have created a site using wordpress and WAMP stack. In my Apache i have enabled **mode_rewrite** , so my site is showing permalinks perfectly.
Now i have hosting provider of .NET and IIS server. So when i migrated my site to live server it is working fine without permalinks. But when i type using raw url like www.example.com/?p=12 it is working fine. So how can i make it work with IIS just like Apached did..
Is there anything in IIS like **mode_rewrite** in Apache | Thanks to @rofflox and @toscho for giving me the link. web.config file was not created as i was working on localhost as WAMP i.e Apache and it required when i shifted to production as it was running IIS.
So i created a blank web.config file and added the following content.
<rewrite>
<rules>
<rule name="Main Rule" stopProcessing="true">
<match url=".*" />
<conditions logicalGrouping="MatchAll">
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
</conditions>
<action type="Rewrite" url="index.php" />
</rule>
</rules>

Add metabox without the container
I want to add a second input identical in design/functionality to the Title text input, directly beneath it.
I can use
add_meta_box('catchy_title', 'Short Title', array('catchyTitle', 'metaBoxShow'), 'post', 'normal', 'high');

<div id="titlewrap">
<label for="catchy_title" class="">Enter shorter title here</label>
<input type="text" autocomplete="off" id="catchy_title" value="'.$meta.'" size="20" name="catchy_title">
</div>
However this puts a grey metabox around it. Should I even be using a metabox? I basically want to duplicate this field:
!title
but I end up with
!wrong
and it's under the rich text editor too.
Here is the full code if it helps: < | Use the action `edit_form_after_title`.

header specific meta box result detect url

if( isset( $header_meta ) ) {
echo '<h1>' . $header_meta . '</h1>';

else {
echo '<h1>Knowledgebase</h1>';
