You are acting on awfully big assumption that something like that would improve performance. Spoiler — no, it won't. The load process in very loose terms consists of: Optionally running code responsible for looking up definitions (autoload or custom). Parsing the file or retrieving results from opcode cache. Loading results to be used. The "autoload is ...

the_permalink echos out the permalink of the current post to the frontend. get_permalink however returns it as a variable, but does not echo it out. You can also pass a post ID to it if you want the permalink of another post. the_permalink is equivalent to: echo get_permalink(); Which is very close to what it actually does. This is the implementation of ...

This has always been a bugbear for me - the lack of on-demand image sizing, and the subsequent number of files you can end up with if you have lots of sizes! I can see the logic behind your efforts - the trouble is, add_image_size only truly comes into play at point-of-upload. As such, is_page_template(..) will always be false. A quick google dug up Aqua ...

functional interpreted code will always be faster then OOP one. Compare function hello_mark() { echo 'hello mark'; } hello_mark(); with class mark { function say_hi() { echo 'hello mark'; } } $m = new mark(); $m->say_hi(); I think it is obvious what is faster to interpret and execute. People don't do OOP because it is faster, they do ...

Best of luck to you, but this won't improve performance in any real way. WordPress is indeed becoming more and more object oriented, over time and with incremental changes. Every update in the last 4 years has refactored some major piece of code into a more class oriented design. Nevertheless, OO and autoload and other things like this are not inherently ...

Here's an example of the data returned from the wp_get_update_data() function: Array ( [counts] => Array ( [plugins] => 3 [themes] => 2 [wordpress] => 0 [translations] => 0 [total] => 5 ) [title] => 3 Plugin Updates, 2 Theme Updates ) So the number of ...

If you need this to be a PHP solution. You could do something like this using 'the_content' filter. This will add the class name "content-img-wrap" to any paragraph that wraps only an image tag when Wordpress prints your post content. So this will not wrap a paragraph with an image and a span. See update if that is what your looking for. add_filter( ...

The problem is that you can't distinguish form an anonymous function and another, so yes, it is possible to remove a closure (i.e. anonymous function) but if more than one closure act on same filter at same priority you have to make a choice, remove them all, ore remove only one (without knowing exactly which). I'll show how to remove them all using a ...

When using Ajax API, and you want to make the ajax callback available for non-logged users, you need to add 2 actions, "wp_ajax_{$action}" and "wp_ajax_nopriv_{$action}". Using only the first action, the callback will be called only for logged users, using only the second it will be called only for non-logged visitors. Try this: function check_username() ...

wp_get_update_data() returns an array in this format counts plugins themes wordpress translations total title So, if you want total count, you need to use it like this $updates = wp_get_update_data(); echo $updates['counts']['total'];

If this is how it looks: <img class="alignleft size-medium wp-image-8530" alt="..." src="#" width="413" height="275" /> <img class="alignleft size-medium wp-image-8529" alt="..." src="#" width="413" height="275" /> Then you have to put them together like this: <img class="alignleft size-medium wp-image-8530" alt="..." src="#" width="413" ...

I am not sure why your query is returning more IDs than necessary. The $args for get_users look correct. By default get_users does not support orderby=rand, but you can overwrite that option. See below: function random_user_query( &$query ) { $query->query_orderby = "ORDER BY RAND()"; } // Usage: [random_users how_many = 3] add_shortcode( ...

PHP has a function, get_included_files() that returns all the file have been includedduring a request. However, if you use that fucntion you obtain all the files required: WordPress core files, plugin files... You need a way to: filter out files that do not belong to theme and child theme (if any) include only files loaded after main template has been ...

As @cybmeta already pointed out, you are too early with your removal. So you have to defer the actual removal, for instance like so: add_action( 'after_setup_theme', 'wpdev_170663_remove_parent_theme_stuff', 0 ); function wpdev_170663_remove_parent_theme_stuff() { remove_action( 'after_setup_theme', 'et_pb_setup_theme' ); }

Note that if any script in the header at all needs jQuery then it will bump it to header, regardless if it's changed to be enqueued for footer. So while changing it to be queued for footer makes sense it rarely works out when a lot of script stuff is going on.

You can make use of the conditional tag is_page_template() This Conditional Tag allows you to determine if you are in any page template. Optionally checks if a specific Page Template is being used in a Page. This is a boolean function, meaning it returns either TRUE or FALSE. You can try something like if( is_page_template( 'template-flat.php' ) ) { ...

All you can do is bump the priority of your hook: add_action( 'wp_head', 'dns_prefetch', 0 /* Highest priority */ ); but does this put my code just after the start of tag? No, but it will output before any other function attached to wp_head i.e. other <link />'s, most stylesheets, plugin scripts etc. To put it right after <head> you'll ...

What you are looking for is a "MU-Plugin"-- "Must-Use Plugin".. Originally these were called "Multi-User Plugins" and were intended for exactly your purpose-- to provide a way for site admins to enable functionality on all sites of an installation. Create a directory at /wp-content/mu-plugins/ and put your PHP file(s) in it. WordPress will load the files ...

You need to use one add_theme_support() call for each feature. Per the Codex, the proper function call is: add_theme_support( $feature, $arguments );

I am doing something like this in one of my plugins: function my_body_class( $c ) { global $post; if( isset($post->post_content) && has_shortcode( $post->post_content, 'your-shortcode' ) ) { $c[] = 'your-class'; } return $c; } add_filter( 'body_class', 'my_body_class' ); I'm not sure it was really necessary, but I ...

Is there more efficient ways to validate the quotes using the WordPress api? I think you should set a nonce for the form You also should check if current user has capability to save quote To get properly sanitize values form $_POST look at filter_input and/or filter_input_array I don't see performance issues on validation, but a possible ...

Redeclaring a function in a child theme only works when the parent themes' function is wrapped in a if( !function_exists( 'function_name' )): condition. Then you can simply just copy the complete function to the child theme and do whatever modifications you need to do. If the parent themes' functions aren't wrapped in that if conditional statement, and ...

Here's a much better solution: Don't edit the theme's functions.php file. Don't put your custom code into that file either. If you have snippets of code for a site, put them into a custom plugin. Put each one into its own plugin, in fact. Separate them by functionality. I even made a handy dandy plugin to make this easier, called Pluginception. The nice ...

The is_login_page() function is taken from here function is_login_page() { return in_array($GLOBALS['pagenow'], array('wp-login.php', 'wp-register.php')); } function my_redirect() { //if you have the page id of landing. I would tell you to use if( is_page('page id here') instead //Don't redirect if user is logged in or user is trying to sign ...

This should hopefully do the trick: /** * Append the image categories to the current image class. * * @see http://wordpress.stackexchange.com/a/156576/26350 */ add_filter( 'get_image_tag_class', function( $class, $id, $align, $size ) { foreach( (array) get_the_category( $id ) as $cat ) { $class .= ' category-' . ...

Anywhere in your script, you can define a global variable as follow: Using the superglobal $GLOBALS array. This array is predefined by PHP, and is available in all scopes. It's an associate array, containing all global variables as a key-value pair. ie: the key will be the variable name, and value will be the value of the variable. ...

If I understand the problem setup correctly, you could try to do the break and widget class counting within the wp_nav_menu_objects filter. Here's an updated example, it's rather expanded because of the extra debug part: add_filter( 'wp_nav_menu_objects', function( $items, $args ) { // Only apply this for the 'primary' menu: if( ...
