#WP ENQUEUE SCRIPT WAS CALLED INCORRECTLY WORDPRESS HOW TO#

Wp_enqueue_script( 'custom-gallery', plugins_url( '/js/gallery.js', _FILE_ ), array( 'jquery' ), '1.0', true ) add_action( 'wp_enqueue_scripts', 'my_plugin_assets' ) Our example above would load the scripts in the footer if we modify it slightly. The enqueuing mechanism can add scripts to the footer using the fifth parameter (the fourth being an optional version number). This increases apparent page load times and can prevent your website from hanging while loading scripts, especially if they contain AJAX calls. Whenever you can get away with loading scripts in the footer, you should. WordPress now knows which scripts we need and can calculate which order they need to be added to the page. That said, it may be a good idea to state all dependencies, just to make sure nothing can break if you forget to include a dependency. Note that even though our second script relies on jQuery, we do not need to specify this, as our first script will already load jQuery. Let’s assume that the first script is a gallery, the second is an extension to that which makes images open up in a lightbox. Wp_enqueue_script( 'custom-gallery-lightbox', plugins_url( '/js/gallery-lightbox.js', _FILE_ ), array( 'custom-gallery' ) ) Here’s an example: add_action( 'wp_enqueue_scripts', 'my_plugin_assets' ) If you have dependencies of your own, you will need to register them, otherwise your scripts won’t load. You can find a list of scripts and styles available in WordPress in the Codex. We do not need to register or enqueue jQuery ourselves because it is already a part of WordPress. Wp_enqueue_script( 'custom-gallery', plugins_url( '/js/gallery.js', _FILE_ ), array( 'jquery' ) ) Our example above would most probably rely on jQuery so let’s specify that now: add_action( 'wp_enqueue_scripts', 'my_plugin_assets' ) The third parameter is an array of registered scripts/styles that need to be loaded before the current asset is enqueued. You can also use the enqueuing functions right away if you don’t need to separate them. WordPress’ enqueueing mechanism has built-in support for dependency management, using the third argument of both wp_register_style() and wp_register_script() functions. add_action( 'wp_enqueue_scripts', 'my_plugin_assets' ) Īdd_shortcode( 'custom_gallery', 'custom_gallery' ) In a real-world example we could use the wp_enqueue_scripts hook to register the assets and the shortcode’s function to enqueue them. If I were to separate the two functions I would do so by using them in different hooks.

Wp_enqueue_script( 'custom-gallery', plugins_url( '/js/gallery.js', _FILE_ ) ) Wp_enqueue_style( 'custom-gallery', plugins_url( '/css/gallery.css', _FILE_ ) ) In fact, you can use the enqueue functions to register and enqueue right away, by using the same arguments as you do in the register functions: add_action( 'wp_enqueue_scripts', 'my_plugin_assets' )

In the example above I registered and enqueued the assets within the same function, which is a bit redundant. Wp_register_script( 'custom-gallery', plugins_url( '/js/gallery.js', _FILE_ ) ) Wp_register_style( 'custom-gallery', plugins_url( '/css/gallery.css', _FILE_ ) ) Within the hooked function you can use the wp_register_script(), wp_enqueue_script(), wp_register_style() and wp_enqueue_style() functions. To enqueue scripts and styles in the front-end you’ll need to use the wp_enqueue_scripts hook. Enqueueing Basics With wp_enqueue_scripts

The way to make this happen is to register the script first, and only actually enqueue it when the shortcode is shown (suggested reading: The Ultimate Guide to WordPress Shortcodes). For example: If you’re building a custom gallery shortcode that uses Javascript you only actually need to load the JS when the shortcode is used – probably not on every page. Sometimes you’ll want to let WordPress know about an asset, but you may not want to use it on every page. The reason for having two steps has to do with modularity. 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. There are two steps taken when enqueueing a script or a style. Enqueueing Basics With wp_enqueue_scripts.
