Is it possible to grab the custom post type post id just only from slug?

As much i know we can get from id by using title. But there can be same title in a custom post type so as slugs are unique is it possible???

You can use get_page_by_path() - don't let the name fool you, third argument is the post type:

if ( $post = get_page_by_path( 'the_slug', OBJECT, 'post_type' ) )
    $id = $post->ID;
    $id = 0;

If you just want the post id this will do the trick in one line.

url_to_postid( site_url('the_slug') );

    The url_to_postid is a very flexible function: you can pass in any kind of permalink/full URL and get the most accurate post-ID for that URL. However, because of the flexible usage it's quite slow (esp. with lot of endpoints/post-types). If you only pass in a slug for a specific post type, it's a lot faster to use get_page_by_path()

  • Good solution for when you're not sure of the post type.

If you wait a couple of days, and upgrade to Wordpress 4.4 which will be released the 8th of December (AFAIK), you can use the new post_name__in parameter in WP_Query which takes an array of slugs


If you need the complete post object

$args = [
    'post_type'      => 'my_custom_post_type',
    'posts_per_page' => 1,
    'post_name__in'  => ['post-slug']
$q = get_posts( $args );
var_dump( $q );

If you only need the ID

$args = [
    'post_type'      => 'my_custom_post_type',
    'posts_per_page' => 1,
    'post_name__in'  => ['post-slug'],
    'fields'         => 'ids' 
$q = get_posts( $args );
var_dump( $q );
  • Nice, but probably a bit intensive to get one post by slug? Why did they add that feature!? Dec 3, 2015 at 12:36

    @TheDeadMedic Mighty be a bit intensive yes, haven't really tested performance on this, just added as means of an alternative ;-). As to why, I really do not know, looks like one of those nice-to-have-unnecessary things that WordPress is so famous for. The naming convention, IMHO, is also wrong, just like the post_name property and category_name parameter, which should have been slug and not name Dec 3, 2015 at 12:48
  • Nice :) wow actually for me its nice update :)

    @TheDeadMedic There is no time difference between my method and your method. I constantly get between 0.002 and 0.005 seconds to run each of our queries. Also, both methods run 1 query only. ;-) Dec 3, 2015 at 17:10

    @TheDeadMedic I just meant PHP has less work to do - yes, for sure, totally agree. It is just always nice to know alternatives (although it might sometime not be the best) and having some kind of benchmarks. Enjoy ;-) Dec 3, 2015 at 17:34
