检查以下代码-

add_action( \'admin_init\', \'the_dramatist_add_role_caps\', 999 );
function the_dramatist_add_role_caps() {
    // Add the roles you\'d like to administer the custom post types
    $roles = array( \'editor\', \'administrator\' );

    // Loop through each role and assign capabilities
    foreach($roles as $the_role) {

        $role = get_role($the_role);

        $role->add_cap( \'read\' );
        $role->add_cap( \'read_{Post_Type_A_Name}\' ); // Also do for Post_Type_B
        $role->add_cap( \'read_private_{Post_Type_A_Name}s\' ); // Also do for Post_Type_B
        $role->add_cap( \'edit_{Post_Type_A_Name}\' ); // Also do for Post_Type_B
        $role->add_cap( \'edit_{Post_Type_A_Name}s\' ); // Also do for Post_Type_B
        $role->add_cap( \'edit_others_{Post_Type_A_Name}s\' ); // Also do for Post_Type_B
        $role->add_cap( \'edit_published_{Post_Type_A_Name}s\' ); // Also do for Post_Type_B
        $role->add_cap( \'publish_{Post_Type_A_Name}s\' ); // Also do for Post_Type_B
        $role->add_cap( \'delete_others_{Post_Type_A_Name}s\' ); // Also do for Post_Type_B
        $role->add_cap( \'delete_private_{Post_Type_A_Name}s\' ); // Also do for Post_Type_B
        $role->add_cap( \'delete_published_{Post_Type_A_Name}s\' ); // Also do for Post_Type_B

    }
}

通过这种方式，您可以向任何用户角色添加权限。

如果要为应获得权限的用户创建新角色，请创建如下新角色-

function add_the_dramatist_role() {
    add_role(\'the_dramatist_role\',
             \'The Dramatist Role\',
             array(
                 \'read\' => true,
                 \'edit_posts\' => false,
                 \'delete_posts\' => false,
                 \'publish_posts\' => false,
                 \'upload_files\' => true,
             )
    );
}
// Remember this must be called plugin main file.
register_activation_hook( __FILE__, \'add_the_dramatist_role\' );

然后添加the_dramatist_role 到上一个函数the_dramatist_add_role_caps\'s$roles 像这样的变量-

$roles = array( \'the_dramatist_role\', \'editor\', \'administrator\' );

现在the_dramatist_role 将拥有所有这些特权。

希望以上帮助。
