Usage: $unique_slug = wp_unique_post_slug( $slug, $post_ID, $post_status, $post_type, $post_parent ); Then you can test if $slug === $unique_slug and generate a new one if the test fails. You can find the function in wp-includes/post.php. It ends with a filter ‘wp_unique_post_slug’, so … Read more

How to schedule multiple posts while adding new
