php - joomla 2.5.4 和模块 JXTC Virtuemart 产品墙

Question

我正在使用 joomla 做网站。我安装了模块 JXTC Virtuemart 产品墙。但此模块未显示，它显示错误“警告：在第 174 行的 Z:\home\megapolis.loc\www\modules\mod_jxtc_vmwall\tmpl\default_parse.php 中为 foreach() 提供的参数无效”。请帮助解决此错误。这是一个文件 default_parse.php

// Get product params
$product = array('min_order_level' => 0, 'max_order_level' => 0);
$item_params = explode('|', $item->product_params);

    $aux[1] = str_replace('"', '', $aux[1]);
if ( isset($aux[0]) && isset ($aux[1]) && ((int)$aux[1] > 0) )
    $product[$aux[0]] = $aux[1];

如果您尝试对不是数组的变量执行 foreach，则可能会发生为 foreach() 提供的无效参数。也许它“应该”是一个数组，也许你认为它是一个数组，但抱歉——它不是。
