  • 5.3.0

Registers support of certain features for a post type.

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', ) );

			$_wp_post_type_features[ $post_type ][ $feature ] = $args;
		} else {
			$_wp_post_type_features[ $post_type ][ $feature ] = true;
