我有一个名为“投资组合”的自定义帖子类型，我使用脚本设置了特色图片，该脚本拍摄了一些我希望每天使用wordpress.org服务更新的网站的快照
http://s.wordpress.com/mshots/v1/' . urlencode($site) . '?w=' . $width;
脚本运行后，我在媒体库中找到图像并且它们似乎附在帖子上，但如果我检查帖子，则没有任何特色图像，图像也不会显示在前面结束。 我在这里发布我正在使用的脚本，我希望有人可以帮助我。

编辑1 以下是我声明自定义帖子类型的地方：
function create_portfolio() {
$labels = array(
'name' => __('Portfolio' , 'portfolio-plugin'),
'singular_name' => __('Portfolio' , 'portfolio-plugin'),
'add_new' => __('Aggiungi testata', 'portfolio-plugin'),
'add_new_item' => __('Aggiungi nuova testata' , 'portfolio-plugin'),
'edit_item' => __('Modifica testata', 'portfolio-plugin'),
'new_item' => __('Nuova testata', 'portfolio-plugin'),
'all_items' => __('Tutte le testate', 'portfolio-plugin'),
'view_item' => __('Vedi le testate' , 'portfolio-plugin'),
'search_items' => __('Cerca testata' , 'portfolio-plugin'),
'not_found' => __('Nessuna testata inserita', 'portfolio-plugin'),
'not_found_in_trash' => __('Work Not found in the trash', 'portfolio-plugin'),
);
$args = array(
'labels' => $labels,
'public' => true,
'rewrite' => array('slug' => 'portfolio'),
'has_archive' => true,
'hierarchical' => true,
'menu_position' => 22,
'menu_icon' => 'dashicons-welcome-write-blog',
'supports' => array(
'title',
'editor',
'thumbnail',
'excerpt',
'page-attributes'
),
);
register_post_type('portfolio', $args);
}
答案 0 :(得分：0)
使用'supports' => array( 'thumbnail' )
支持参数：
register_post_type( $post_type, $args );
