使用PHP獲取Joomla中的用戶組ID

Question

要在Joomla 2.5.15中獲取用戶組ID，我在此處遵循Joomla文檔中的文檔

我的代碼看起來像這樣：

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

但是這段代碼產生錯誤：注意：未定義屬性：JUser :: $ gid in輸出中沒有任何組ID。

Answer 1

試試這個：

$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

來自DOCS

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