仅为特定的 Joomla 用户组加载 css 样式

问题描述

我想执行一个 css 样式，但只针对特定的 Joomla 用户组.我的目标是将 php 代码直接包含在我的 Joomla 模板中.

I would like execute a css style but only for a specific Joomla user group. My goal was to include the php code directly inside my Joomla template.

我尝试找到方法(我不是编码员)并且我做了一些测试但没有成功.例如，我在论坛中找到了此代码:

I try to found how to do (I'm not a coder) and I make some test but without success. For example I found this code in a forum:

<?php
$user =& JFactory::getUser();
if (!$user->author) {
?>
<style>#myclass{display:none; width:0px;}</style>
<?php
}
?>

但这不起作用，因为我想通过用户组 ID 执行样式，还因为此代码似乎适用于 Joomla 1.5 而我使用的是 Joomla 2.5.

But this don't work because I want execute the style by Usergroup ID and also because this code seem to be for Joomla 1.5 and I'm under Joomla 2.5.

请问有什么线索吗?

推荐答案

$user =& JFactory::getUser();
$groupIDs = array();
foreach( $user->groups as $groupID ){
  $groupIDs[] = $groupID;
}

var_dump( $groupIDs );

如果您的 $groupIDs 数组包含您需要的 id，请像您现在所做的那样回显样式.请记住 $groupIDs 是一个数组，因此您将遍历该数组以查找所需的 id.使用 foreach 来完成它.

If you $groupIDs array contains the ids you need echo the styles as you have done now. Remember $groupIDs is an array, so you will have loop through the array to find the ids you need. Use a foreach to get it done.

如果您有任何问题，请告诉我.

If you have any issues let me know.

根据要求更新答案.

$user =& JFactory::getUser();
$groupIDs = array();
foreach( $user->groups as $groupID ){
  $groupIDs[] = $groupID;
}
foreach($groupIDs as $groupID)
{
 if($groupID == 2)
 {
 echo '<style>#myclass{display:none; width:0px;}</style>';
 }
}
