Naming script handles right way
I was wondering is there any convention or what is the right way for naming handles in `wp_register_script()` and `wp_register_style()` functions?
For example if I am developing a plugin that uses modernizer, is it better simply naming it 'modernizer' or something unique like 'my-script-modernizer'?
If it is better to have unique handles and I am developing multiple plugins and I'm sure all uses same script. Should I use same handle in all plugins? | This question does to a degree solicit opinionated answers, but I feel it's a good one nonetheless.
As far as _my opinion_ goes and the way I handle things is this:
Definitely use the same handle for the same script in all your plugins and/or themes. You don't want to load exact duplicates, if two of your plugins are used in the same WP install.
I give a generic handle to widely used and renowned scripts such as modernizr. Why should such a script be loaded more than once, under different handles?
I prefix handles of my own scripts, for reasons of namespacing. | stackexchange-wordpress | {

How does WordPress search work behind the scenes?
I am using WordPress search to search a range of custom post types and allow the user to drill-down into each individual post type.
However I'm finding that WordPress is not returning what I'd deem to be the 'best' matches first. For example, if I search for Microsoft, pages that contain the term irregularly are still returned before pages that regularly use the term.
Basically I'm trying to find some information on how WordPress ranks pages and determines relevance and if I can influence this **without having to install any plugins**.
Any help much appreciated. | **EDIT** \- The current version of WordPress supports relevance, so this answer is no longer accurate.
* * *
There's no concept of rank or relevance, it's just a simple LIKE query on the post title and content:
($wpdb->posts.post_title LIKE '{$n}{$term}{$n}') OR ($wpdb->posts.post_content LIKE '{$n}{$term}{$n}')
You can use the `posts_search` filter to modify or completely replace the search query with your own. From `/wp-includes/query.php`:
// Allow plugins to contextually add/remove/modify the search section of the database query
$search = apply_filters_ref_array('posts_search', array( $search, &$this ) );
Also see the available query filters on the `WP_Query` Codex page. | stackexchange-wordpress | {

featured image as background image on pages
I'm adding a featured image on my page through the dashboard and I want to use it as a background image on the container div of the page. I want to apply the background image through css, so I am thinking to put a style attribute inside my markup. I'm thinking to make something like this:
<div id="<?php echo $post_name; ?>" class="page<?php echo $post_id; ?>" style="background: url(<?php wp_get_attachment_image_src( get_post_thumbnail_id(), 'large' ); ?>) !important;">
But unfortunately this is not working.
When I check the output is like this:
background: url() !important;
What is wrong with this ? Any suggestions? Thanks! | You need to `echo` the return value from `wp_get_attachment_image_src()`. It also returns an `Array()`, so you need to grab the needed part from that array. In this case it's the first/`0` value. Example:
<?php $thumb = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), 'full' );?>
<div id="post" class="your-class" style="background-image: url('<?php echo $thumb['0'];?>')">

Add product category to post_class

global $post;

Why is setlocale() returning false on WPEngine?
It appears that WPEngine does not have support for different locale strings, rendering `setlocale()` useless.
`setlocale(LC_ALL, "es_ES");` returns `false` and immediately after that, `setlocale(LC_ALL, 0)` (as you would expect from the previous `false`, returns `"en_US"`. | The issue with `setlocale()` is not the function itself. It is that WPEngine _only_ has English language locales installed (the complete list is below) and cannot realistically install any other locales. Because I needed to just print some Spanish language dates (not change the entire WordPress installation to Spanish), I wound up creating an array of the date strings in question and writing a function that parses them if necessary (or sends the result to `strftime()`):
The array is here:

are there any downsides to increasing the number of most recent items in a feed
The default number of items to show in a rss feed is 10 (Settings-Reading)
Is there any reason why I shouldn't show all items.
When I use feeds from other sources (not wordpress) it seems like they show all the items.
Is there any performance hit on the server for showing a large number of items? | You can increase the number of items safely. Feed creation is pretty fast. It is just a simple loop through the latest posts, no scripts are loaded, no pagination, widgets or other expensive operations.
For your subscribers, more items are better, because they can explore your content faster. Make sure to use a full text feed, excerpts are rarely useful. | stackexchange-wordpress | {

Rewrite url / permalink for default archive - yearly / monthly
I want to change the structure of yearly/monthly archive URL of default post type `'post'`.
As we know be default the URLs are like:
Default: `
but want them rewritten, so end up like this:

I'd like someone to point to the right direction, need more info do leave a comment.

open selected wordpress post with javascript

Does the FD Feedburner plugin create feeds for categories
I have setup the FD Feedburner plugin. I want to get feeds for each of my categories. Do I need to manually create feeds for categories in Feedburner? or Does the plugin automatically create feeds for categories.
Here is another older link to the plugin | I think this is how it works:
You need to manually create feeds in Feedburner.com for categories. You can use a URL like this: feeds.feedburner.com/Lovefood_burgers
In wordpress you would create the main feed in the FD Feedburner plugin: feeds.feedburner.com/Lovefood
Choose the option: Append category/tag to URL for category/tag feeds ...
Now when you select a category feed in Wordpress, it will redirect to the category feed that you setup in Feedburner.com
btw, I am pretty sure this is correct. However, I figured this out by experimenting, not be looking at source code or by validation from anyone else (i tried) - so there is a chance I could be incorrect. | stackexchange-wordpress | {

how to change/remove/hide menu under installed plugins
Recently I install one plugin. After installing the "bookingwizz" plugin, the menu added in menu. Under bookingwizz I now have some submenu as well. Now I don't need all those menu items, but want to keep some and change some name and remove some. So how would I do that? I tried to search in that plugins file and also in database, but never found anything. Here's a screenshot of the menu
> !enter image description here | ### Solution using Codes
To hide a menu from a plugin menu, you need to look for the plugin hook. And after finding the hook, `remove_submenu_page()` will help you to achieve the desired task done. Using the hook and the `remove_submenu_page()`, you can remove the submenu exactly from that plugin.
For a complete understanding of the whole, refer to the article like:
> **The Complete Guide To The WordPress Settings API** \- Tom McFarlin
Then to know how to unset something you may refer to this WPSE thread.
### Easy Solution
But for an easy solution, you can use **Adminize** , a free WordPress plugin that will assist you to show/hide certain menu and/or services by the admin roles:

how to set context in Wordpress for unit testing

$tweets_table = $wpdb->prefix . 'zam_tweets';
$result = $wpdb->get_var("SELECT tweet FROM $tweets_table WHERE post_id = '$post_id'");
$content = $result;
}
return $content;
My problem is how do I set the context to be that of a specific post so that I will get an actual post id when using the `get_the_ID()` method. Is this how I'm supposed to go with this or do I just have to specify them as arguments? | If you have phpUnit configured for testing a WP plugin, you can use a test case like this:
In your `plugin-directory/tests/Some_Test_Case.php`:
class Plugin_Test extends WP_UnitTestCase {
/**

*/
public function test_something( $post_id, $expected_result ) {

return array(
array( 1, 'expected result for post_id = 1' ),

'all' hook and get_option issue
code listing: <
I ran into a trouble with my plugin. (It is a class based plugin actually) I'm trying to use `get_option` function. When I just make `var_dump(get_option('option_name', 1))` somewhere in `plugin_options` function (you'll see the code listing) - it outputs `int(1)`
The problem is that I cannot use `get_option` inside my `log_to` method. The `log_to` method is bound to 'all' hook. So I guess that's why it doesn't work. (even `wp` is not loading at all)
Anyone knows the resolution? | `get_option` fires hooks itself so you are triggering a infinite loop (or something similar if not actually infinite). Your callback calls `get_option`, which triggers the hooks used by `get_option`. Each hook triggers the callback again, which used `get_option` which triggers the hooks used by `get_option`. And so on...
Get your option value in the constructor, outside of the callback method. That way, when your callback runs it is inadvertently triggering itself. Proof of concept:
class WP_Test_Logging_Plugin {
static $data = array();
public function __construct() {
$this->data = get_option('option_name', 1);
add_action( 'all', array( $this, 'log_to' ) );
}

$hook = current_filter();
var_dump($hook,$this->data);

Is there a WordPress equivalent to MediaWiki templates

Mouse over the site that you need to edit and select **Edit** in the menu that appears.
Now select the **Settings** tab. Scroll down to the bottom (or near the bottom, depending on whether you have plugins installed that add more settings at the bottom). You're looking for the **Site Upload Space Quota** setting. Put the appropriate number of MB in that box -- if you're updating a site's quota to 1GB, for instance, you'd put `1024` in the box.

Hook when category is added to post
I'm trying to do something when a category is added to post and saved. I thought that using the `save_post` hook would have registered when a category is added to a post, but it doesn't appear to.
When I edit a post and do nothing but change the categories for the post, I don't get the `save_post` hook fired (editing the title, body, etc fires the `save_post` hook successfully). Is there another way to use `add_action`/`add_filter` to detect when a category is added to a post? | You may want to try:
do_action('set_object_terms', $object_id, $terms, $tt_ids, $taxonomy, $append, $old_tt_ids);

add_action('set_object_terms','wpse5123_set_object_terms',10,4);

if($taxonomy == 'category'){
echo '<pre>';
print_r($terms);

custom single.php not working
Trying to solve this issue for the past hour and I can't figure out what's going on.
Trying to create `single-blog.php` (I have a few posts which are under the category 'blog') but Wordpress automatically redirects these posts to single.php! I've flushed the permalinks by **settings** > **permalink** > **save changes** but still nothing happens. To test & to see if Wordpress picks up on single-blog.php the code I used was:
<?php get_header(); ?>
<h1>TEST HERE</h1>

As you can see you have only three options:
1. `single-{post_type}.php`
2. `single.php`
3. `index.php`
It means that you can't create a template for posts related to `blog` category. So you shouldn't use `single-blog.php` template, use `single.php` instead and add there something like this:
<?php get_header(); ?>
<?php if ( has_category( 'blog' ) : ?>
<h1>TEST HERE</h1>
<?php else : ?>

How to make method from plugin available in theme?

Wordpress multilingual site to work with other plugins
I have a project in which the client needs the site to support 5 different languages. After some research on Google and here, it's clear the two ways to do it would be either using Multilingual plugins or Multi-site.
My question is, if I were to use the wordpress plugins such as qTranslate, how would the other plugins work, i.e slideshows, testimonials etc. For example, most of the slideshow plugins comes with only a single title fields. In that sense, is using plugins for the translation still efficient keeping in mind that I am going to be using sidebars and other plugins which don't support multingual?

Be aware, some poorly written themes and plugins will not work with any multi-language plugin.

Get 1 more post in loop

if(get_post_meta($post->ID, 'skip_me', true) == true){

// as we really want 3 total!

} else {
the_content();

If a certain condition is met, we might pass over a post, but what if we still _really_ want to get exactly 3 posts? Rather than arbitrarily asking for extra posts and then stopping after 3 successes - is there any other way to ask of the loop, to get one more post?
I suppose with this exact example the easiest thing would be to do a `meta_query` within the arguments. But what if it weren't that easy? | You should probably add a meta query to your `WP_Query()` args:

// Meta Query
'meta_query' => array(
array(
'key' => 'skip_me',
'value' => 'true',
'compare' => '!='
)
)
)
);
Or you could perhaps go with the simpler version in this case:
$loop = new wp_query(
array(
'posts_per_page' => 3,
// Meta Query
'meta_key' => 'skip_me',
'meta_value' => 'true',
'meta_compare' => '!='
)
);

Removing short versions of category archive URL
I'm looking after a site where someone has configured /%category%/%postname% as the Permalink structure.

How to allow hidden custom fields to be added from wp-admin/post.php?
I know that using an underscore in front of a custom field name hides it from display on the front-end, e.g. `_custom_field_name`. In my experience, WordPress also prevents one from adding such a custom field on the front end.
Before I go spelunking around core, I wanted to ask: Is there an "easy" way to allow `_custom_fields` to be added from wp-admin/post.php?

!what i get | I found the following filter, here unlocking all protected meta data:

{
$allowed = array( '_edit_lock', '_test', '_wp_page_template' );

the_title(); works in a page template, outside the loop. Why?
Trying to wrap my head around the loop concept...
Given a template page (page-work.php) with just this code:
<?php the_title(); ?>
WP correctly shows the title of that page. As I understand it, this is outside any loop and shouldn't work (Codex says to use `get_the_title` in those cases).
So the question is, why does it work?
Funnily enough, this won't output the title + content, just the title:
<?php the_title(); the_content(); ?>
Thanks! | The global `$post` object exists already for singular views before `wp_head` is called. It is just not filled with all data.
The `the_title()` calls `get_the_title()` which in turn calls `get_post()`. And _that_ calls `$GLOBALS['post']` if no post ID has been passed.

Any way to resize an image without crop and add new blank space?
Using image_resize() from wordpress. | First of all pay attention that `image_resize()` function is deprecated! Use `wp_get_image_editor()` instead of it. This function will return an instance of `WP_Image_Editor` class (or WP_Error if some issues appear during loading your image). This class has `resize` method which accepts three arguments: desired width, desired height and crop flag.
Sample usage:
$editor = wp_get_image_editor( '/path/to/file.png' );
if ( !is_wp_error( $editor ) ) {
$editor->resize( $desired_width, $desired_height, true ); // true - do crop, false - don't crop
}
Back to your question. Unfortunately there is no way to do what you want to do. Your image aspect ratio doesn't equal to desired aspect ratio, that is why whitespace appears. If you crop the image, you will loose parts of your image from top and bottom, but in this case you won't see whitespaces... | stackexchange-wordpress | {

Link to file in plugin directory from wordpress template?

In my themes header.php file I want to include a php file which just contains html, from my plugin directory.
The path is basically /wp-content/plugins/my_plugin/my-html.php
I can't seem to figure out the proper code for wordpress to look in the plugins directory, and grab the my-html.php file from within the my_plugin folder. I want to include this file so the html in it is included in the header.php within my theme.

Why does WordPress add 0 (zero) to an Ajax response?
Unless I end Ajax processing function by `exit()` or `die()`, the Ajax function receives desired and correct output but following by `0`.

add_action('wp_ajax_nopriv_get_homepage', 'get_homepage');
function get_homepage(){
echo "get_homepage ->";

}
I've read at AJAX in Plugins, but why is that necessary? | The default response from `admin-ajax.php` is,
`die( '0' );`
...by adding your own `wp_die()` or `exit()` or `die()` after returning your desired content prevents the default response from `admin-ajax.php` being returned as well.

In which version of WordPress was the new gallery shortcode implemented?

The gallery shortcode codex page says the following:
> "It's important to note that this style of gallery shortcode is not new to 3.5, however it is much easier to generate and manage with the new Media Workflow introduced in 3.5."
Does anyone know what the minimum WP version is, in which this style of gallery shortcode will still work? | The file `/wp-includes/media.php`, where the Gallery Shortcode is defined, first appears in WordPress 2.5.
It has the **`id`** (singular) attribute to refer to the `post_parent`:

* * *
The **`ids`** (plural) attribute appears in WordPress 3.5, and is used to `include` attachments:
if ( ! empty( $attr['ids'] ) ) {
$attr['include'] = $attr['ids'];
}
...
$_attachments = get_posts( array('include' => $include

Exclude taxonomy term from all loops, but having it on widget
I have excluded a custom post type taxonomy term from all posts like this:
add_action( 'pre_get_posts', 'exclude_category_posts' );
function exclude_category_posts( $the_query ) {
$taxquery = array(
array(
'taxonomy' => 'product_cat',

'terms' => array( 157 ),
'operator' => 'NOT IN'
)
);
$the_query->set( 'tax_query', $taxquery );
return $the_query;
}
But I need that taxonomy term to be included back in a specific widget loop and only for that specific widget. Is there any chance for that?
The reason I followed the above way, because I have created a product category, which I'd like to be shown only on a widget I created and nowhere else except search queries and the taxonomy term page. On all other loops I'd like it excluded. | Looks like you've excluded a taxonomy _term_ , not the whole taxonomy. Is that what you intended?
But on to the answer...
Right before your query in the widget add:
remove_action( 'pre_get_posts', 'exclude_category_posts' );
And then you probably want to put it back again after that query by repeating:
add_action( 'pre_get_posts', 'exclude_category_posts' );

Is there a way to look up the non-rewritten url based on the friendly one? Then just pull the article ID from there via regex?
To further clarify:
Say this is the URL <
Can I take it back (decode) to? <
So I can grab the 123 and use that to find the author and excerpt. | There is a function called `url_to_postid`
$id = url_to_postid( get_permalink(40) ); // $id will be 40
Actually (WP 3.6) it works only for standard posts and page, but with WP 3.7 it will also work for custom post types. | stackexchange-wordpress | {

Display more than 10 posts on author.php file
it seems that there are only 10 posts being displayed on author.php file. The theme I'm using have just this in author.php file:-
<?php while ( have_posts() ) : the_post(); ?>
<?php endwhile; ?>
<?php wt_pagination(); ?>
The loop is getting only first 10 posts (of the author). How can I change it to first 30 posts. Without writing a secondary (custom) loop. | when you use the loop the number of post displayed is choosen fron the option set in _Settings->Reading_ in you backend. It affects all the standard loops, not only the author page.
To change only for author page you have to use `pre_get_posts` hook and set the wanted number of posts using `posts_per_pag`e argument:
add_action('pre_get_posts','change_numberposts_for_author');
function change_numberposts_for_author( $query ) {
if ( ! is_admin() && $query->is_main_query() && is_author() ) {
$query->set('posts_per_page', 30); // 30 is the number of posts

Select custom post by meta value
Say I've got the custom post type `foo` with a meta box called `bar`. I've posted an entry with `bar` = `pineapple`. Now I want to check if there is a `foo` in the database with a `bar` set to `pineapple`. How would I do that?
I've managed to get this working using a `wpdb` query but that doesn't feel right. Is there an elegant, maybe built-in way for me to do this? | I think you mean a query like this one:
$args = array(
'post_type' => 'foo',
'meta_key' => 'bar',
'meta_value' => 'pineapple',
'posts_per_page' => 1,
);
$query = new WP_Query( $args );
You can check out further information here on _meta queries_ in `WP_Query`.
If you only want to check if there exists such a post, you can use the `found_posts` property:
if( $query->found_posts > 0 ){
// do stuff
}
or the usual way with the `have_posts()` method:
if( $query->have_posts() ){
// do stuff

How to use wp_nav_menu with hashtag links?
I am developing a custom theme and the navigation part uses hashtags (yes, all content is on one page). So when i use
wp_nav_menu( array( 'theme_location' etc
the menu items links to the pages. Can i use/edit wp_nav_menu so it adds a # for every page link, like
mysite.com/about-us/
becomes
mysite.com/#about-us/
Or should i create a custom menu function?
bonus question: Why doesn't wp_get_nav_menu_items give me the permalink/slug for post_name but just the post number as post_name? (see < | You already hinted it yourself: When you look at `wp_get_nav_menu_items()` you'll see that the resulting Array of items gets mapped over with `wp_setup_nav_menu_item()` \- in other words, this function gets applied to each and every nav menu item.
In there you can hook into the `'wp_setup_nav_menu_item'`-filter with its `$menu_item` argument, or use one of the filters in the applied functions in between. The level of control just lays in what you use where (look up source). The argument itself is an object that you can influence. | stackexchange-wordpress | {

Get plugin directory from a theme
Does anyone know a non-hacky way of getting the plugin directory path from within a theme's functions.php?
I've used plugin_dir_path( **FILE** ), but because its called in the theme's functions.php it returns the path to that file. Not the plugins directory. I could string manipulate it and add the plugins path, but that feels nearly as bad as hardcoding the whole path.
I have got it working using:
require_once( ABSPATH .'/wp-content/plugins/ehu-events/event-widget.php' );
But I know that's so oldschool and wrong and I'd probably be shunned from the wordpress community for using it!
Is there a standard wordpress function I can use for this? | Maybe what you're looking for is :

How to calculate total number of comments made by a particular user

Sticky Posts Not Sticking to Top of Category Archive
I'm using my index.php to display post archive pages rather than a specific archive.php file.
This works fine, however sticky posts do not stick to the top of it. They do however, stick to the top of the posts page.
Are sticky posts not supposed to stick to the top of archive pages?
Here is the code for the loop I'm using; loop-index.php \- <
Am I doing something wrong? Or is this just default functionality? | By default, sticky posts only stick to the top of the first page of the main blog posts index.
The easiest way to show sticky posts in other contexts is probably via a custom loop, e.g.:
$sticky_posts = new WP_Query( array(
'post__in' => get_option( 'sticky_posts' )
) );
if ( $sticky_posts->have_posts() ) : while ( $sticky_posts->have_posts() ) : $sticky_posts->the_post() );
// Loop markup here
endwhile; endif;
// IMPORTANT
wp_reset_postdata();

How to solve Woocommerce Memory Limit

W3 Total Cache Minification - Any way to not use php?

Post/Page Publish/Update button not clickable once I make an edit

Only when making the initial edit is in not clickable.

How to I make my post title link to a custom field
I have a custom field in my posts called `post_bookmark_url` which contains a link. I want the post title that is displayed in the excerpts on my home page to link to the `post_bookmark_url` rather than the permalink of the post. (I am doing this to create a Drudge Report type of aggregator.)
How can I make the "post title" in the excerpts on the home page link to a custom field? | I assume that the post title markup looks something like so:
<h1><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h1>
You merely need to replace `<?php the_permalink(); ?>` with your post custom meta value:
<?php $post_bookmark = get_post_meta( get_the_ID(), 'post_bookmark_url', true ); ?>
<h1><a href="<?php echo $post_bookarmk; ?>"><?php the_title(); ?></a></h1>
Other caveats:
* You'll want to consider the _context_ in which you use this code. If you only need it in your **Blog Posts Index** , then create a `home.php` template file, and put it there. That way, your post titles are not impacted in other contexts.
* You'll probably want to use some fallback in case `post_bookmark_url` isn't set. | stackexchange-wordpress | {

How to remove custom post type archive
I have a custom post type called "recipe" with the `has_archive` parameter set to true. Visiting mysite.com/recipe/ gives a basic archive list of all the recipes posted and a page title of "Recipes". So far so good.
Now I'm looking to disable that recipe archive page (but keep individual recipe links working). My first thought was to try setting `has_archive` to false, which sounds like it should do the trick. Nope. The only difference this makes is the page title which for some reason becomes the name of the site. The actual archive is still displayed.
What is the best way to actually remove that archive completely? Is there a parameter of `register_post_type` that will achieve this or is it impossible and a case of a custom page template with a redirect in it?
Thanks. | The `has_archive` parameter for `register_post_type()` does exactly what you expect it to do. However, it modifies rewrite rules when set. So, if you change it to `false`, you'll need to **flush your rewrite rules** in order for the archive index display to be removed entirely. | stackexchange-wordpress | {

date_query seems to be ignored by wp_query
