如果您设置\'has_archive\' => TRUE 在里面register_post_type() 帖子类型将有自己的提要/books/feed/ 其项目不包括在主提要中。

示例插件

<?php
/*

*/
! defined( \'ABSPATH\' ) and exit;

add_action( \'init\', \'wpse13006_register\' );

// Call wp-admin/options-permalink.php once after activation to make permalinks work
function wpse13006_register()
{
    register_post_type(
        \'wpse13006\'
    ,   array (
            \'has_archive\'         => TRUE
        ,   \'label\'               => \'wpse13006\'
        ,   \'public\'              => TRUE
