How to get list of Scripts in Order of Dependencies

All the information you need you can get from the global variable $wp_scripts: Code: function wpse124227_wp_script_styles_debug_basic() { global $wp_scripts, $wp_styles; echo ‘<pre>’; //Scripts print_r( $wp_scripts ); //Styles //print_r( $wp_styles ); echo ‘</pre>’; } add_filter( ‘wp_head’, ‘wpse124227_wp_script_styles_debug_basic’ ); To get a more specific output you have to define what you are looking for, instead of printing … Read more

Identifying the priority of style.css so I can make a small CSS file load last

When you properly enqueue a file, an instance of the wp_styles (more on this) class is created. The priority of actions is ignored. So it doesn’t matter if you write anything like add_action (‘wp_enqueue_scripts’,’function_adding_main_style’,10); add_action (‘wp_enqueue_scripts’,’function_adding_small_style’,11); The reason is exactly the existence of the dependency system. WP first collects all enqueued style files and then … Read more

Conditionally dequeue dependency of scripts

Solution 1: Here we will dequeue and deregister elementor-dialog and elementor-frontend, then we will re-register elementor-frontend without the elementor-dialog dependency: // This needs to fire after priority 5 which is where Elementor // handles enqueueing scripts. We’re ok since the default is 10. add_action( ‘wp_enqueue_scripts’, ‘wpse_elementor_frontend_scripts’ ); function wpse_elementor_frontend_scripts() { // Optionally add guard clauses … Read more

How to modify/extend/override a core method?

There’s already a simliar answer by toscho here. Based on this one and from a look at WP_Styles, which extends WP_Dependencies and _WP_Dependency, I can’t see a reason why it should not work: Whatever got added as extra–conditional, gets thrown in: // ~/wp-includes/class.wp-styles.php if ( isset($obj->extra[‘conditional’]) && $obj->extra[‘conditional’] ) { $tag .= “<!–[if {$obj->extra[‘conditional’]}]>\n”; $end_cond … Read more

WordPress check for fatal error while activating plugin, so simplest solution will be trigger a fatal error and this will prevent WordPress to activate the plugin. In my below code I … Read more

Add a script as a dependency to a registered script

Digging through https://github.com/WordPress/WordPress/blob/3.5.1/wp-includes/class.wp-dependencies.php all registered scripts are stored in the global $wp_scripts. You can access them directly through that, but I prefer to use the API when it exists. In this case, $wp_scripts->query() returns a particular registered script (a _WP_Dependency object – see source). A _WP_Dependency object stores the dependencies as an array of handles, … Read more

Concatenate and minify dependencies for enqueued JavaScript files

W3 Total Cache offers JS/CSS minification. I’m not familiar with the process they use, but if you are wanting to avoid using a plugin, you could take a look at their source code how they handle it.
