How to use edit_form_advanced action in WordPress

Alright, so you’re diving into WordPress hooks! Let’s talk about the edit_form_advanced action. This one fires after the ‘normal’ context meta boxes have been output for all post types except ‘page’. It’s quite handy if you need to add some custom functionality when editing posts. You’ll need to register it using add_action, and you can do this either in your theme’s functions.php file or through a custom WordPress plugin. Pro tip: creating a custom plugin is usually the better way to go, as it ensures everything stays intact when your theme updates.

Here’s a breakdown of how to use this hook. You’ll define a function, register it, and can even remove it if needed. Let’s jump into some live examples to make it clearer.

Example 1: Basic Usage

In this example, a function execute_on_edit_form_advanced_event is defined to be executed when the edit_form_advanced action occurs.

    function weplugins_execute_on_edit_form_advanced_event($post) {
        // Custom functionality for when the edit form advanced action occurs
        echo '<p>Custom message: This is triggered by edit_form_advanced action.</p>';
    }
    add_action("edit_form_advanced", "weplugins_execute_on_edit_form_advanced_event", 10, 1);
    

Example 2: Using Parameters

Here’s how you can use the parameters passed to your function to implement custom functionality based on the post object.

    function weplugins_edit_form_advanced_custom($post) {
        if ($post->post_type == 'post') {
            echo '<p>Custom functionality for posts.</p>';
        } else {
            echo '<p>Custom functionality for other post types.</p>';
        }
    }
    add_action("edit_form_advanced", "weplugins_edit_form_advanced_custom", 10, 1);
    

Example 3: Removing the Hook

If you need to remove a previously registered hook, here’s how you can do it. Make sure you provide the same callback function name, priority, and number of arguments.

    remove_action("edit_form_advanced", "weplugins_execute_on_edit_form_advanced_event", 10, 1);
