There are multiple ways to do it actually, but the way I want to show you also assumes you have created your settings page correctly. For this to work correctly all scripts and styles must be enqueued. How do we go about only loading JS files on those pages? It’s actually quite easy. Enqueuing style.css For the longest time, themes would hardcode a link to style.css in. Most pages are named pretty straight forward, so it’s easy to figure out which files display which pages, but what about custom admin pages? Many (if not most) plugins create custom settings pages in the WordPress admin.

Don’t forget to change the script and style handle name and path to the file. Add this code to functions.php file to add scripts and styles in WordPress admin for all pages. This hook will be the same for both scripts and style. Wp_enqueue_script( 'custom-js', plugins_url( 'js/custom.js', dirname(_FILE_) ) ) Īdd_action('admin_enqueue_scripts', 'pw_load_scripts') To enqueue any scripts and styles in admin, WordPress provides a hook adminenequeuescripts.

This example displays the jQuery library for the custom_script.Function pw_loading_scripts_wrong_again ( ) Īdd_action ( 'admin_enqueue_scripts', 'pw_load_scripts' ) If the handles of these dependencies are not already registered, WordPress will not link the new script. Using this WordPress automatically links all the dependencies to the HTML page prior to be linked to new script. JavaScript files which are integrated into themes mostly require other JavaScript files that should be loaded beforehand to utilize its functions or variables.Using this $deps parameter, the wp_enqueue_script() and wp_register_script() functions enables us to point the dependencies when registering a new script. Link a Theme Script Which Depends on jQuery Enqueueing is the process of loading Javascript files or JS files - including scripts and styles to WordPress in a way that lets you use them whenever you need them without requiring the rewriting of code. It needs the theme to have the wp_footer() template tag in the appropriate place. When the value of parameter is true, the script is placed before end tag. (boolean) These scripts are placed in of the HTML document. If no version is specified, then WordPress automatically adds a version number equal to the current version of WordPress. For example, if a script was enqueued using the loginenqueuescripts hook that. (string) String specifying the script version number, which is integrated towards the end of the path. Each of these areas uses a specific hook to enqueue scripts to use in that area. This parameter is required when the script with the given $handle hasn’t been registered using wp_register_script(). (array) Array of handles of all registered scripts that this script depends upon, such as these scripts must be loaded first. It is only required when the script with the given $handle hasn’t been registered with wp_register_script(). Remote scripts can be specified with a protocol-agnostic URL, e.g. To get a proper URL to local scripts, use plugins_url() for plugins andget_template_directory_uri() for themes.

First you register it tell WordPress it’s there and then you actually enqueue it, which eventually outputs it into the header or just before the closing body tag. What is the idea way to register/enqueue scripts and/or styles for use in plugins I recently made a plugin simple plugin to add the user avatar/gravatar with a shortcode. If the string contains a ‘?’, the preceding part of the string would be referred as the registered handle, and the succeeding part would be appended to the URL. There are two steps taken when enqueueing a script or a style. Going with this extra step for registering followed by enqueuing the script will allow other plugins/themes to deregister your script without modifying the core code of plug-in. (string) Name used as a handle for the script. After providing all parameters in wpregisterscript (), call the wpenqueuescript () to actually enqueue the registered script by it’s handle. It can be handled using a wp_register _script() function or can be provided with all parameters necessary to link a script. Being the most recommended process for associating JavaScript to WordPress pages,Wp enqueue script is used for calling the linked script files on the page at the correct time.
