允许自定义角色访问后端的自定义帖子类型

所以我对此有一些疑问，我不知道为什么。我只需要一个可以访问后端博客的自定义角色。

我添加了一个具有Capability类型的新帖子类型，blog以及一个具有所有上限的新用户角色，这将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帖子类型。但是，具有我的自定义角色的用户根本无法进入后端。

注释的帖子类型参数

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

注册角色

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 );

加盖

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 );

我一直在疯狂地寻找原因。我尝试使用复数，非复数大写字母，尝试将功能添加到帖子类型的args中。但是，我永远无法进入后端。我在主题中没有任何其他代码可能会将用户赶出管理员（我删除了自己的代码，在测试时将他们踢出了管理员）

编辑 在这里，您可以从数据库中看到blog_manager功能的转储，那里还有很多测试BS的功能，但不应该阻止他们从我所知道的信息中登录。

'blog_manager' => array (
    'name' => 'Blog Manager',
    'capabilities' => array (
        'read' => true,
        'edit_posts' => false,
        'delete_posts' => false,
        'publish_posts' => false,
        'upload_files' => true,
        'read_blog' => true,
        'read_private_blog' => true,
        'edit_blog' => true,
        'edit_others_blog' => true,
        'edit_published_blog' => true,
        'publish_blog' => true,
        'delete_others_blog' => true,
        'delete_private_blog' => true,
        'delete_published_blog' => true,
        'blog' => true,
        'read_private_blogs' => true,
        'edit_blogs' => true,
        'edit_others_blogs' => true,
        'edit_published_blogs' => true,
        'publish_blogs' => true,
        'delete_others_blogs' => true,
        'delete_private_blogs' => true,
        'delete_published_blogs' => true,
        'delete_blogs' => true,
        'delete_blog' => true,
    ),
)

很难对上面的代码进行故障排除，因为它只是实际代码的一部分，但这是注册自定义帖子类型（称为Example）和自定义角色（博客管理器）所需的最小插件，该角色可以访问Example自定义帖子类型。

这也可以用作主题的functions.php文件的一部分。只需使用主题激活和停用挂钩即可。

如果您对插件没问题，则可以使用velow插件。
