add_post_type_support() WordPress Function
The add_post_type_support() function enables support for a given feature on a specific post type. This function should be called after the post type has been registered. For example, to add support for the 'title' and 'editor' features to the 'post' post type, you would use the following: add_post_type_support( 'post', 'title' ); add_post_type_support( 'post', 'editor' );
add_post_type_support( string $post_type, string|array $feature, mixed $args ) #
Registers support of certain features for a post type.
Description
All core features are directly associated with a functional area of the edit screen, such as the editor or a meta box. Features include: ‘title’, ‘editor’, ‘comments’, ‘revisions’, ‘trackbacks’, ‘author’, ‘excerpt’, ‘page-attributes’, ‘thumbnail’, ‘custom-fields’, and ‘post-formats’.
Additionally, the ‘revisions’ feature dictates whether the post type will store revisions, and the ‘comments’ feature dictates whether the comments count will show on the edit screen.
A third, optional parameter can also be passed along with a feature to provide additional information about supporting that feature.
Example usage:
add_post_type_support( 'my_post_type', 'comments' );
add_post_type_support( 'my_post_type', array(
'author', 'excerpt',
) );
add_post_type_support( 'my_post_type', 'my_feature', array(
'field' => 'value',
) );Parameters
