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.


参数

$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.

	$features = (array) $feature;
	foreach ($features as $feature) {
		if ( func_num_args() == 2 )
			$_wp_post_type_features[$post_type][$feature] = true;

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

    
    <?php
    add_action('init', 'wpdocs_custom_init');
    
    /**
     * Add excerpt support to pages
     */
    function wpdocs_custom_init() {
    	add_post_type_support( 'page', 'excerpt' );
    }
    ?>
    
  2. 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' ) );

    add_theme_support()
