所以我对此有一些问题，我不明白为什么。我只需要一个自定义角色，可以访问后端的博客。

我添加了一个新的职位类型，其能力类型为blog 以及一个新的用户角色，该角色具有所有大写字母，允许管理员访问用户添加/编辑自定义帖子类型。这适用于管理员，他们可以在后端访问post类型。但是，我的自定义角色的用户根本无法进入后端。

Post type args of note

"capability_type" => \'blog\',
"map_meta_cap" => true,

Register role

function add_blog_manager_role(){
    add_role(
        \'blog_manager\',
        \'Blog Manager\',
        array(
            \'read\' => true,
            \'edit_posts\' => false,
            \'delete_posts\' => false,
            \'publish_posts\' => false,
            \'upload_files\' => true
        )
    );
}
add_action( \'admin_init\', \'add_blog_manager_role\', 4 );

Add Caps

function add_blog_role_caps() {
    $roles = array(\'blog_manager\', \'editor\',\'administrator\');
    foreach($roles as $the_role) {
        $role = get_role($the_role);
        $role->add_cap( \'read\' );
        $role->add_cap( \'read_blog\');
        $role->add_cap( \'read_private_blog\' );
        $role->add_cap( \'edit_blog\' );
        $role->add_cap( \'edit_others_blog\' );
        $role->add_cap( \'edit_published_blog\' );
        $role->add_cap( \'publish_blog\' );
        $role->add_cap( \'delete_others_blog\' );
        $role->add_cap( \'delete_private_blog\' );
        $role->add_cap( \'delete_published_blog\' );
    }
}
add_action(\'admin_init\', \'add_blog_role_caps\', 5 );

我一直在谷歌上疯狂搜索，试图找到这一切的原因。我尝试了复数、非复数大写，尝试了在post-type-args中添加功能。然而，我永远无法进入后端。我在主题中没有任何其他可能将用户踢出管理员的代码（我在测试时删除了自己将用户踢出管理员的代码）

Edit在这里，您可以看到数据库中的blog\\u管理器功能转储，还有很多测试BS，但这不应该阻止他们从我所知的位置登录。
