The post_type_exists function in WordPress is used to check if a given post type exists. This function takes a string parameter representing the post type name and returns a boolean value – true if the post type exists, and false if it does not.
This function is commonly used in WordPress theme and plugin development to ensure that a specific post type has been registered before performing any actions related to that post type.
Example Usage:
if ( post_type_exists( 'product' ) ) {
// Do something if the 'product' post type exists
} else {
// Do something else if the 'product' post type does not exist
}
