我定义了一个自定义的帖子类型“Review”，我想将其与一个自定义的永久链接：/reviews/year/postname一起使用。下面的代码正确地创建了CPT，并且在创建新的“审阅”时，自定义永久链接正确地显示在管理面板中。但是，当单击自定义永久链接时，创建的结果“Review”返回404。现代wordpress解决这个问题的方式是什么？理想情况下，我不想使用任何外部插件。下面的代码是在自定义插件中定义的。

// Register \'Review\' custom post type
add_action( \'init\', \'vidcreate_post_types\' );

// Register the permalink structure desired for \'Review\' posts, with placeholders
add_action( \'init\', \'vidrewrite_rules\' );

// Replace permalink placeholders with actual content
add_filter(\'post_type_link\', \'update_review_link_placeholders\', 10, 2);



/**
 * Custom \'Review\' post type
 */
function vidcreate_post_types() {

    register_post_type( \'review\',
        array(
            \'labels\' => array(
                \'name\' => __( \'Reviews\' ),
                \'singular_name\' => __( \'Review\' )
            ),
            \'public\' =>  true,
            \'has_archive\' => true,
            \'taxonomies\' => array(\'category\', \'post_tag\'),   
            \'rewrite\' => array(
                \'slug\'=>\'reviews\',
                \'with_front\'=> false,
                \'feed\'=> true,
                \'pages\'=> true
            ),
            \'hierarchical\' => true,
            \'menu_icon\' => \'dashicons-video-alt\',
            \'supports\' => array(
                \'title\', \'editor\', \'author\', \'thumbnail\', \'excerpt\', \'comments\', \'revisions\', \'page-attributes\'
            )
        )
    );


}


/**

function vidrewrite_rules(){

    add_rewrite_tag( \'%review_slug%\', \'(reviews)\',\'post_type=review&slug=\' );
