自定义Wordpress Post类型和功能不显示图像或其他Post数据

我无法从该帖子类型中获取附件，以便在下面的函数中进行回显。将呈现空白框，并且未设置URL。任何想法都会有所帮助。我试图让这个功能出现在主页上，但一直得到同样的结果。

// Custom Post Type
register_post_type('inf_home_items', array(
    'labels' => array(
            'name'   => 'Items of the Week',
            'singular_name' => 'Items This Week',
            'add_new' => __( 'Add New' ),
            'add_new_item' => __( 'Add New Items' ),
            'view_item' => 'View Items This Week',
            'edit_item' => 'Edit Story',
            'new_item' => __('New Items of The Week Story'),
            'view_item' => __('View Items of the Week Story'),
            'search_items' => __('Search Items of the Week Stories'),
            'not_found' =>  __('No entries found'),
