Wordpress - How to get custom post type by slug?

Question

I'm in a situation where I need to get a WP post (custom post type) and the only information I have is its slug. I don't know what custom post type it is, just that it's a cpt.

Is this possible to do, and if so, how?

Answer 1

global $wpdb;
$the_slug = 'post-slug-here'; // <-- edit it
$myrows = $wpdb->get_results( "SELECT post_name, post_type, ID FROM wp_posts WHERE post_name = '". $the_slug ."'" );
foreach ( $myrows as $myrow ) 
{
    echo 'Post Type: ' . $myrow->post_type . ' Post ID: ' . $myrow->ID;
}

Answer 2

I know this is a late reaction, but I stumbled upon this. Be careful with such queries because it can be easely injected with SQL vulnerabilities whan you grab the slug from your url.

Answer 3

If you know for sure all the custom post types that were defined in your WordPress theme or plugins, it's probably better to use a dedicated function like get_page_by_path(). It will prevent users from trying to inject SQL in a query.

For example :
get_page_by_path( 'slug_of_the_post', OBJECT, [ 'list', 'of', 'possible', 'types' ] );

See code reference of the function.
