How to use get_sample_permalink filter in WordPress

Example 1: Basic Usage of get_sample_permalink

To start using the get_sample_permalink filter, you first need to register it using add_filter. You can write this code into the functions.php of your activated theme or in a custom WordPress Plugin. This helps ensure that nothing breaks when you update your WordPress Theme in the future.

    function weplugins_modify_permalink($permalink, $post_id, $title, $name, $post) {
        // Example modification to the permalink
        return $permalink;
    }
    add_filter('get_sample_permalink', 'weplugins_modify_permalink', 10, 5);
    

Example 2: Conditional Modification

Sometimes, you need to modify the permalink conditionally. Here’s how you can achieve that with a custom function.

    function weplugins_conditional_permalink($permalink, $post_id, $title, $name, $post) {
        if ($post->post_type === 'custom_post_type') {
            // Modify the permalink for custom post type
            $permalink[0] = home_url('/custom/' . $name);
        }
        return $permalink;
    }
    add_filter('get_sample_permalink', 'weplugins_conditional_permalink', 10, 5);
    

Example 3: Removing the Hook

Sometimes, you need to remove a registered hook. You can use remove_filter to remove the get_sample_permalink filter.

    remove_filter('get_sample_permalink', 'weplugins_modify_permalink', 10, 5);
    

Ensure you provide the same callback function name, priority, and number of arguments when removing the hook callback.
