Question

我们正在开发一个基于k2的网站。为此，我们利用extrafields给文章一个特定的css类。

但是当我们使用归档扩展时，这个类没有应用，我们收到错误。

这是我们得到的错误

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

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 -->

        <?php endif; ?>

<!-- End K2 Generic (search/date) Layout -->

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相应的id（右侧）

对我而言， id 11

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

Joomla K2在generic.php上显示了额外的字段
