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

Registers support of certain features for a post type.


Description 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 Parameters

$post_type

(string) (Required) The post type for which to add the feature.

$feature

(string|array) (Required) The feature being added, accepts an array of feature strings or a single string.

$args

(mixed) (Optional) extra arguments to pass along with certain features.

    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' ) );
