How to use postmeta_form_keys filter in WordPress

Example 1: Basic Implementation

Here’s a simple example of how to implement the postmeta_form_keys filter. This example demonstrates how you can apply the filter within your theme or plugin.

    add_filter('weplugins_postmeta_form_keys', 'weplugins_meta_form_keys');

    function weplugins_meta_form_keys($keys, $post) {
        // Your custom logic here
        return $keys;
    }
    

Example 2: Adding a Custom Meta Key

In this example, we’ll show you how to add a custom meta key to the dropdown list. This is particularly useful when you want to include additional metadata in your custom fields.

    add_filter('weplugins_postmeta_form_keys', 'weplugins_add_custom_meta_key');

    function weplugins_add_custom_meta_key($keys, $post) {
        $keys[] = 'weplugins_custom_meta_key';
        return $keys;
    }
    

Example 3: Removing a Hook Callback

If you need to remove a previously added hook callback, here’s how you can achieve it. This can be useful when you want to ensure certain functions are not executed.

    // Remove the filter
    remove_filter('weplugins_postmeta_form_keys', 'weplugins_meta_form_keys', 10);
