请搜索相关文档和具体源代码，不用重复发帖了！！！

add_filter('wpjam_post_types', 'wpjam_franke_add_product_post_types');
function wpjam_franke_add_product_post_types($wpjam_post_types){
	$wpjam_post_types['product']  = array(
		'label'				=> '产品',
		'public'			=> true,
		'show_ui'			=> true,
		'has_archive'		=> true,
		'menu_position' 	=> 4,
		'menu_icon'	  		=> 'dashicons-products',
		'rewrite'			=> false,
		// 'rewrite'			=> array('slug'=>'product','with_front'=>false,'feeds'=>false),
		'permastruct'		=> 'product/%post_id%/',
		// 'capability_type'	=> 'mp',
		// 'thumbnail_column'	=> false,
		'postviews_column'	=> false,
		'supports'			=> array(
