I need to update post slug when post title is changed. I've got the below code so far which doesn't work- perhaps you can suggest why? Cheers.

add_action('cred_save_data', 'build_post_title', 10, 2);
	function build_post_title($post_id, $form_data) {

		// Get current title
		$title = get_the_title();
		$slug = sanitize_title($title);

		// Update the post into the database
		$my_post = array(
			'post_name' => $slug
		);
		wp_update_post( $my_post ); 

	}

Hi David

Always helps to check the documentation first: https://codex.wordpress.org/Function_Reference/wp_update_post

>> You must include "ID", otherwise a WP_Error will be thrown.

You can also save a function call, as the title is available in the $_REQUEST object, so try the following:

add_action( 'cred_save_data', 'build_post_title', 10, 2 );
function build_post_title($post_id, $form_data) {
 
    // Get current title
    $title = $_REQUEST['post_title'];
    $slug = sanitize_title($title);
     
    // Update the post into the database
    $my_post = array(
        'ID'    => $post_id,
        'post_name' => $slug
    );
    wp_update_post( $my_post ); 
}

Note that you aren't limiting this to a particular form, it will apply to all Toolset Forms.

Cheers, managed to sort it out from there.
