使用PHP获取Joomla中的用户组ID

Question

要获取Joomla 2.5.15中的用户组ID，我按照Joomla Documentation here

中的文档进行操作

我的代码如下所示：

$user = JFactory::getUser();
echo "<p>Your group id is {$user->gid}.</p>";

但是这段代码产生错误：注意：未定义的属性：JUser :: $ gid in 输出中没有任何组ID。

Answer 1

尝试使用：

$user   = JFactory::getUser();
$groups = $user->get('groups');

foreach ($groups as $group)
{
    echo '<p>Group = ' . $group . '</p>';
}

Answer 2

jimport( 'joomla.access.access' );
$groups = JAccess::getGroupsByUser($user_id, false);
var_dump($groups);

Answer 3

FROM DOCS

$user = JFactory::getUser(99); 
echo "<p>Your usertype is {$user->usertype} which has a group id of {$user->gid}.</p>";
