Description

This Conditional Tag checks if a post type exists by passing a post type name an argument. This is a boolean function and uses a global $wp_post_types variable for checking the post type existence, meaning it returns either TRUE if the post type exists or FALSE if it doesn't exist. The post type must be a registered post type.

Usage

<?php post_type_exists( $post_type ); ?>

Parameters

$post_type

(string) (required) Post type.

Default: None

Return Value

(boolean) 

True on success, false on failure.

Examples

if ( post_type_exists( 'book' ) ) {
   echo 'the Book post type exists';
}

$exists = post_type_exists( 'post' );
// returns true
 
$exists = post_type_exists( 'page' );
// returns true
 
$exists = post_type_exists( 'book' );
// returns true if book is a registered post type
 
$exists = post_type_exists( 'xyz' );
// returns false if xyz is not a registered post type
