WordPress：自定义用户角色无法访问自定义帖子类型|“对不起，您不能访问此页面”

时间：2021-07-21 作者：Scott White

The Objective:创建自定义帖子类型，并仅授予管理员和自定义角色查看/控制它的权限。

The Problem:对于管理员来说，它工作得非常好，但对于我得到的自定义角色：Sorry, you are not allowed to access this page.

起初，我认为这可能只是访问它的能力问题，但这段代码却有所不同：

add_submenu_page( /*  STAFF PAGES   */
                \'redacted\', //Parent Menu Slug
                \'Staff Pages\', //Page Title text
                \'Staff Pages\', //Menu Title text
                \'edit_staff\', //Capability required for this menu to be displayed by user
                \'edit.php?post_type=staff\' //Link to page
);

自定义角色可以看到指向自定义帖子类型的链接，但无法访问该链接。还有，跑步print_r($wp_roles->get_role( \'supervisor\' )->capabilities); 确实表明该角色正确地拥有必要的能力。关于如何解决这个问题，我已经有了一些理论，但到目前为止，还没有一个得到证实。

我的代码如下：

function initialize_plugin(){
//Non-relevant code redacted
add_action( \'admin_init\', array($this, \'admin_init\') );
}
function activate(){
    $this->custom_post_types();
    $this->adjust_user_roles();
    //Non-relevant code redacted
}



/* My Custom Post Type */
function custom_post_types(){
            register_post_type( \'staff\', array(
                \'labels\' => array(
                    //labels redacted
                ),
                \'has_archive\'       => false,
                \'hierarchical\'      => true,
                \'menu_icon\'         => \'dashicons-groups\',
                \'capability_type\'   => array(\'staff\', \'staffs\'),
                \'map_meta_cap\'      => true,
                \'public\'            => true,
                \'show_in_menu\'      => false,
                \'rewrite\'           => array( \'slug\' => \'staff\', \'with_front\' => false ),
                \'supports\'          => array( \'title\', \'thumbnail\', \'custom-fields\', \'revisions\'),
                \'show_in_rest\'      => true,
                \'taxonomies\'        => array( \'member-type\' ),
                \'menu_position\'     => 2,
            ));



/* My Custom Role */
function adjust_user_roles(){
$wp_roles = new WP_Roles(); 

$wp_roles->add_role(
              \'supervisor\', __( \'Supervisor\' ),
               array(
                    //General
                    \'moderate_comments\'         => true,
                    \'upload_files\'              => true,
                   
                    //Blog Posts
                    \'read\'                      => true,
                    \'read_post\'                 => true,
                    \'edit_post\'                 => true,

SOLUTION:玩了一会儿，我意识到我绝对是个白痴，而且想得太多了。而我之前在this similar post, 我最终用他们的代码代替了我的代码，发现它实际上适用于我的用例。在试图理解原因的过程中，我开始尝试将其转换为我的，并很快找到了问题的根源：

/* My Custom Post Type */
function custom_post_types(){
            register_post_type( \'staff\', array(
                \'labels\' => array(
                    //labels redacted
                ),
                \'has_archive\'       => false,
                \'hierarchical\'      => true,
                \'menu_icon\'         => \'dashicons-groups\',
                \'capability_type\'   => array(\'staff\', \'staffs\'),
                \'map_meta_cap\'      => true,
                \'public\'            => true,
/*---------> */ \'show_in_menu\'      => false, /* <---------*/
                \'rewrite\'           => array( \'slug\' => \'staff\', \'with_front\' => false ),
                \'supports\'          => array( \'title\', \'thumbnail\', \'custom-fields\', \'revisions\'),
                \'show_in_rest\'      => true,
                \'taxonomies\'        => array( \'member-type\' ),
                \'menu_position\'     => 2,
            ));

为了有一个干净的自定义菜单，我设置show_in_menu 为我制造了问题。当我把它改成\'show_in_menu\' => true, 我的问题解决了。在解决这个问题时，我很想尝试一下remove_menu_page(); 或者考虑一些更优雅的东西。

无论如何，今天的教训是不要过分专注于一个方面。希望这有助于其他人和快乐的编码！
