Post Slug to Tag

[manonatelier]

I created a WordPress function to auto create post tags from post slugs, and it seems to work pretty well, but wondering if it can be improved as I’m a php newbie.

add_action(‘save_post’, ‘slug_to_tag’);
function slug_to_tag($post_id) {
global $post;
$sluggish = $post -> post_name;
$pattern = ‘/-/’;
$replacement = ‘, ‘;
$sluggies = preg_replace($pattern, $replacement, $sluggish);
wp_set_post_terms($post -> ID, $sluggies, ‘post_tag’, true);
}

Thanks for any help!

Had to revise code to this, but would appreciate any input. Thank you!

function slug_to_tag($post_ID) {
$gpt = get_post($post_ID);
$sluggish = $gpt -> post_name;
$pattern = ‘/-/’;
$replacement = ‘, ‘;
$sluggies = preg_replace($pattern, $replacement, $sluggish);
wp_set_post_terms($post_ID, $sluggies, ‘post_tag’, true);
}

add_action(‘save_post’, ‘slug_to_tag’);
