这里是一个很好的文章，它解释了如何让所有用户卷：

如果设置了这个在你的函数，并要求它，你应该获得所有角色：

function getUsersByRole($roles) { 
    global $wpdb; 
    if (! is_array($roles)) { 
     $roles = explode(",", $roles); 
     array_walk($roles, 'trim'); 
    } 
    $sql = ' 
     SELECT ID, display_name 
     FROM  ' . $wpdb->users . ' INNER JOIN ' . $wpdb->usermeta . ' 
     ON  ' . $wpdb->users . '.ID    =  ' . $wpdb->usermeta . '.user_id 
     WHERE ' . $wpdb->usermeta . '.meta_key  =  \'' . $wpdb->prefix . 'capabilities\' 
     AND  (
    '; 
    $i = 1; 
    foreach ($roles as $role) { 
     $sql .= ' ' . $wpdb->usermeta . '.meta_value LIKE \'%"' . $role . '"%\' '; 
     if ($i < count($roles)) $sql .= ' OR '; 
     $i++; 
    } 
    $sql .= ') '; 
    $sql .= ' ORDER BY display_name '; 
    $userIDs = $wpdb->get_col($sql); 
    return $userIDs; 
}
