我们正在开发一个基于k2的网站。为此，我们利用额外字段为文章提供特定的 css 类。

但是当我们使用归档扩展时，这个类没有被应用，我们得到一个错误。

这是我们得到的错误

警告：在第 19 行的 /home/recall/domains/domain.com/public_html/templates/mytemplate/html/com_k2/generic.php 中为 foreach() 提供的参数无效

这是代码

<!-- START: Call to prepare extra fields -->
<?php  
//convertArray to use ids as key
$extrafields = array();
foreach($this->item->extra_fields as $item)
{    
$extrafields[$item->id] = $item->value;
}   
?>    
<!-- END: Call to prepare extra fields -->

我自己找到了解决方案。

对于正确的值，在k2额外字段的后端找到对应的id（在右边）

对我来说是id 11

<?php echo $extrafields[11];?>
