I am looking for a way to test if a post is a custom post type. For example, in, say, the sidebar I can put in code like this:

 if ( is_single() ) {
     // Code here

I want code testing for only a custom post type.


Here you are: get_post_type() and then if ( 'book' == get_post_type() ) ... as per Conditional Tags > A Post Type in Codex.

    @Rarst This only apply to the single post template of a CPT. get_post_type() is the right way to go in a more broad approach. (eg: on a search page) Dec 26 '20 at 20:40

    @amarinediary I think at the time the question was unclear if the interest is in checking main page-defining post or just some post in an arbitrary loop. The appropriate way to express with template tag would vary accordingly. :)

if ( is_singular( 'book' ) ) {
    // conditional content/code

The above is true when viewing a post of the custom post type: book.

if ( is_singular( array( 'newspaper', 'book' ) ) ) {
    //  conditional content/code

The above is true when viewing a post of the custom post types: newspaper or book.

These and more conditional tags can be viewed here.


Add this to your functions.php, and you can have the functionality, inside or outside of the loop:

function is_post_type($type){
    global $wp_query;
    if($type == get_post_type($wp_query->post->ID)) 
        return true;
    return false;

So you can now use the following:

if (is_single() && is_post_type('post_type')){
    // Work magic
  • Thank you, this is very useful! But it should be: if (is_single() && is_post_type('post_type')){ //work magic } The closing bracket was missing.... Many greetings, Ethel

  • Has this stopped working for anyone else? I've used this for ages, but suddenly this stopped working for me. However, using the same method without global $wp_query always works: if ( 'post-type' == get_post_type() ) {} Jan 13 '17 at 13:39

    is_post_type() is depreciated. Dec 21 '17 at 12:23

To test if a post is any custom post type, fetch the list of all not built-in post types and test if the post’s type is in that list.

As a function:

 * Check if a post is a custom post type.
 * @param  mixed $post Post object or ID
 * @return boolean
function is_custom_post_type( $post = NULL )
    $all_custom_post_types = get_post_types( array ( '_builtin' => FALSE ) );

    // there are no custom post types
    if ( empty ( $all_custom_post_types ) )
        return FALSE;

    $custom_types      = array_keys( $all_custom_post_types );
    $current_post_type = get_post_type( $post );

    // could not detect current type
    if ( ! $current_post_type )
        return FALSE;

    return in_array( $current_post_type, $custom_types );


if ( is_custom_post_type() )
    print 'This is a custom post type!';

  • any idea how to check the post type in the backend?

  • @evavienna This code works everywhere. You just need a post object.

If for any reason you already have access to the global variable $post, you can simply use

if ($post->post_type == "your desired post type") {

If you want a wild card check for all your custom post types:

if( ! is_singular( array('page', 'attachment', 'post') ) ){
    // echo 'Imma custom post type!';

This way you don't need to know the name of your custom post. Also the code still work even if you change the name of your custom post later.


To determine the $post_type easily inside a function, you need to call the global post var first, here is an example:

function the_views() {
global $post;

if ($post->post_type == "game") {
   $span = '<span class="fa-gamepad">';
  } else { // Regular post
    $span = '<span class="fa-eye">';
