如何在Joomla 2.5中获取用户组名称

问题描述：

我正在编写我在Joomla 1.7中开发的Joomla 2.5组件.我一直在使用这样的代码:

I'm writing a Joomla 2.5 component that I had been developing in Joomla 1.7. I have been using code like this:

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

$ groups数组将包含一个以组名作为索引的ID列表. Joomla 2.5似乎已经放弃了此功能.我一直无法找出如何在不直接查询数据库的情况下获取组名.有什么方法可以获取用户所属的组列表，而不必诉诸于数据库?

The $groups array would contain a list of ids with the group name as the index. Joomla 2.5 seems to have scrapped this functionality. I have been unable to find out how to get the group names without directly querying the database. Is there any method for getting a list of the groups a user is a member of without having to resort to querying the database?

答

我在下面生成的代码获取用户所属的所有组的名称，并将它们存储在变量 $ groupNames 中.以换行符分隔:

The code I generated below gets the names of all the groups the user is a part of and stores them in the variable $groupNames separated by line breaks:

foreach ($user->groups as $groupId => $value){
    $db = JFactory::getDbo();
    $db->setQuery(
        'SELECT `title`' .
        ' FROM `#__usergroups`' .
        ' WHERE `id` = '. (int) $groupId
    );
    $groupNames .= $db->loadResult();
    $groupNames .= '<br/>';
}
print $groupNames;

从技术上讲，它是通过Joomla API来查询数据库的.在Joomla 2.5上，这对我来说效果很好.

It technically queries the database but is done via the Joomla API. This is working well for me on Joomla 2.5.
