How to auto-assign custom page slugs to WordPress pages automatically

To auto-assign custom page slugs to WordPress pages automatically, you can use the wp_insert_post_data filter to modify the slug before the page is saved to the database. Add the following code snippet to your theme’s functions.php file:

1. In your WordPress admin dashboard, go to “Appearance” > “Theme Editor.”
2. In the right sidebar, locate and click on the “functions.php” file.
3. Add the following code snippet at the end of the file:

function auto_assign_custom_page_slug($data, $postarr) {
    // Check if the post is a 'page' post type and if it's a new post being inserted
    if ($data['post_type'] === 'page' && $postarr['ID'] === 0) {
        // Create a custom slug based on the current date and time
        // You can modify this to create a custom slug according to your requirements
        $custom_slug = 'page-' . date('Ymd-His');
        
        // Assign the custom slug to the post
        $data['post_name'] = sanitize_title($custom_slug);
    }

    return $data;
}
add_filter('wp_insert_post_data', 'auto_assign_custom_page_slug', 10, 2);

This code snippet creates a function called auto_assign_custom_page_slug() that checks if the post is a new page, and if so, it generates a custom slug based on the current date and time. You can modify the $custom_slug variable to create a custom slug according to your requirements.

4. Click “Update File” to save the changes.

Now, when you create a new page in WordPress, a custom slug will be automatically assigned to it.

Remember to always backup your files before making any changes, and test your changes on a staging site or local development environment before applying them to your live site.
