Tip: Custom Scripts In WordPress

WordPress is a great CMS (Content Management System) is you want to get a site up and running very quickly. It’s themable and within the theming framework, WordPress includes the ability to include popular assets like JQuery. All it takes is a simple command.

<?php
wp_enqueue_script('jquery');

What if you don’t want to use the version of JQuery included in WordPress though? There are several reasons you would require a different version, compatibility for example.

In order to use a custom asset you can do something like the following.

<?php
wp_deregister_script('jquery');
wp_register_script('jquery', 'http://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.min.js', false);
wp_enqueue_script('jquery');

This will deregister the current jquery script which is the default included with WordPress and set it to your custom version. You can also register your own scripts like this.

<?php
wp_register_script('myajaxscript', 'mythemedir/js/ajaxstuff.js', false);
wp_enqueue_script('myajaxscript');
