add_post_type_support( string $post_type, string|array $feature )

Register support of certain features for a post type.

描述

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.

This example adds support for excerpts in pages (assuming it is *not* showing under “Screen Options”):

add_action('init', 'wpdocs_custom_init');

/**

* Add excerpt support to pages

*/

function wpdocs_custom_init() {

add_post_type_support( 'page', 'excerpt' );

}

?>

Unfortunately,

add_post_type_support('page', 'thumbnail');

won’t add featured images to pages. For that you need to [add theme support for post-thumbnails

add_theme_support( 'post-thumbnails', array( 'post', 'page' ) );
