我有来自https://github.com/WebDevStudios/Custom-Metaboxes-and-Fields-for-WordPress/wiki/Field-Types#group的自定义Metabox字段组，其中包含3个字段并显示在产品页面模板上，我想调用客户端添加的最新帖子以在我的首页上显示它们 . 这是自定义字段的代码 .

/**
	 * Repeatable Field Groups
	 */
	$meta_boxes['field_group'] = array(
		'id'           => 'field_group',
		'title'        => __( 'Manage your products here', 'cmb2' ),
		'show_on'      => array( 'id' => array( 11, ) ), // Specific post IDs to display this metabox
		'object_types' => array( 'page', ),
		'fields'       => array(
			array(
				'id'          => $prefix . 'repeat_group',
				'type'        => 'group',
				'options'     => array(
					'group_title'   => __( 'Product {#}', 'cmb2' ), // {#} gets replaced by row number
					'add_button'    => __( 'Add Another Product', 'cmb2' ),
					'remove_button' => __( 'Remove Product', 'cmb2' ),
					'sortable'      => true, // beta
				),
				'fields'      => array(
					array(
						'name' => 'Product Name',
						'id'   => 'product_name',
						'type' => 'text',
					),
					array(
						'name' => 'Product Description',
						'description' => 'Write a short description for this Product',
						'id'   => 'product_description',
						'type' => 'textarea',
					),
					array(
						'name' => 'Product Image',
						'id'   => 'product_image',
						'type' => 'file',
					),
				),
			),
		),
	);

更新：我发现这个http://codex.wordpress.org/Function_Reference/wp_get_recent_posts但我仍然无法弄清楚如何让它从自定义字段中获取帖子
