Automatically update the slug of a product when the title of the product is updated

Question

I want to automatically update the slug of a product when its product title is updated.

I read on some posts that wp_update_post would probably be the best option to start with.

I also tried the code below but it's not working good, it's causing too many conflicts.

Any help please?

You haven't provided any code in your question... and you haven't done thorough research to your problem...

Please see:

• Change slug on post creation - Stackexchange
• Update post slug - wordpress.org
• Update slug in save_post - Github

wp_update_post can be used to update the post slug. It is appropriate for making changes to a post's properties, including the slug.

You can use the save_post action which triggers whenever a post or page is created or updated. It can be used to execute custom functions right after a post is saved.

Then you can use sanitize_title to create a URL-friendly version of the post title. It ensures that characters which are not suitable for URLs are removed or replaced.

The code below will automatically update the slug of a product, when you make updates to the product name/title:

/* Update product slug to product title, when product is saved */
function slug_save_post_callback( $post_ID, $post, $update ) {
    // Prevent function from running during an autosave. Can cause unnecessary updates.
    if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) {
        return;
    }

    // Check if post type is product, if not, exit the function
    if ( $post->post_type != 'product' ) {
        return;
    }

    // Ensures that only users with the appropriate permissions can trigger the function
    if ( ! current_user_can( 'edit_post', $post_ID ) ) {
        return;
    }

    // Generate new slug based on the post title using sanitize_title
    $new_slug = sanitize_title( $post->post_title, $post_ID );
    // If new slug is the same as the current slug, exit the function
    if ( $new_slug == $post->post_name ) {
        return; // already set
    }

    // Remove save_post action to prevent infinite looping
    remove_action( 'save_post', 'slug_save_post_callback', 10, 3 );
    // Update the post slug with new slug
    wp_update_post( array(
        'ID' => $post_ID,
        'post_name' => $new_slug
    ));
    // Re-hook the save_post action to ensure the function is called again
    add_action( 'save_post', 'slug_save_post_callback', 10, 3 );
}
add_action( 'save_post', 'slug_save_post_callback', 10, 3 );

The code should be added to your functions.php file of your active child theme. Tested and works.
