所以我尝试为WordPress制作一个简单的插件。就像一篇评论。甚至试图通过TutsPlus的教程来做到这一点。每次尝试时我都会得到404。然后我从导师那里拿到了代码，在查看我的评论帖子类型帖子时仍然得到了404分。

    function my_custom_posttypes() {

    $labels = array(
        \'name\'               => \'Testimonials\',
        \'singular_name\'      => \'Testimonial\',
        \'menu_name\'          => \'Testimonials\',
        \'name_admin_bar\'     => \'Testimonial\',
        \'add_new\'            => \'Add New\',
        \'add_new_item\'       => \'Add New Testimonial\',
        \'new_item\'           => \'New Testimonial\',
        \'edit_item\'          => \'Edit Testimonial\',
        \'view_item\'          => \'View Testimonial\',
        \'all_items\'          => \'All Testimonials\',
        \'search_items\'       => \'Search Testimonials\',
        \'parent_item_colon\'  => \'Parent Testimonials:\',
        \'not_found\'          => \'No testimonials found.\',
        \'not_found_in_trash\' => \'No testimonials found in Trash.\',
    );

    $args = array(
        \'labels\'             => $labels,
        \'public\'             => true,
        \'publicly_queryable\' => true,
        \'show_ui\'            => true,
        \'show_in_menu\'       => true,
        \'menu_icon\'          => \'dashicons-id-alt\',
        \'query_var\'          => true,
        \'rewrite\'            => array( \'slug\' => \'testimonials\' ),
        \'capability_type\'    => \'post\',
        \'has_archive\'        => true,
        \'hierarchical\'       => false,
        \'menu_position\'      => 5,
        \'supports\'           => array( \'title\', \'editor\', \'thumbnail\' )
    );
    register_post_type( \'testimonial\', $args );
}
add_action( \'init\', \'my_custom_posttypes\' );

// Flush rewrite rules to add "review" as a permalink slug
function my_rewrite_flush() {
    my_custom_posttypes();
    flush_rewrite_rules();
}
register_activation_hook( __FILE__, \'my_rewrite_flush\' );

最上面是php开始标记和插件信息（和往常一样）。尝试了几个主题-仍然得到404。每次测试之前，我都会在Permalinks上保存更改并停用&&；激活了该插件。

有人有什么想法吗？我现在正在学习（昨天开始）。
