Question

我在一个网站（www.theprinterdepo.com）上有一个非常奇怪的问题，谷歌浏览器我看到500内部服务器错误。但是在IE上一个firefox工作得很好）。我注意到的是，如果我转到chrome并点击历史记录并删除所有缓存，cookie等，那么它再次正常工作。

我删除了system.log并再次检查，唯一记录的是这一个：

第一个参数应该是/xxx/xxx/public_html/app/code/local/Mf/Searchterms/Model/Layer.php中的数组

这是我从未接触过的标准magento文件，但这里是代码：

<?php


class Mf_Searchterms_Model_Layer extends Mage_Catalog_Model_Layer

    const XML_PATH_DISPLAY_LAYER_COUNT = 'catalog/search/use_layered_navigation_count';

    {
        if (isset($this->_productCollections[$this->getCurrentCategory()->getId()])) {
            $collection = $this->_productCollections[$this->getCurrentCategory()->getId()];
        } else {
            $collection = Mage::getResourceModel('catalogsearch/fulltext_collection');
            $this->prepareProductCollection($collection);
            $this->_productCollections[$this->getCurrentCategory()->getId()] = $collection;
        }
        return $collection;

        $productIds = array_filter($productIds);
        //var_dump($productIds);

        if(is_array($productIds) && sizeof($productIds) > 0){
            //echo "asd";
            $productIdArray = $productIds;

更新1： 我设法清理apache错误日志，刷新浏览器然后这是日志上的新文本： [client 83.134.115.127]脚本标题的提前结束：index.php

当结果集为空且array_filter需要数组时，第一行（Mage::..）可能返回NULL或FALSE，而不是null / false值！试试这个：

$productIds = Mage::getModel('searchterms/searchterms')->getProducts($query->getId());
if (!$productIds) {
    $productIds = array();
}
$productIds = array_filter($productIds);

但这可能（可能）是使用array_filter的错误方法。如果没有第二个参数，它将过滤任何评估为false的数组元素，例如，如果元素是null，false，empty array，empty string。但我怀疑Mage::getModel(...)->getProducts(...);是否会返回这些元素（对特定情况没有任何了解）。但如果它确实返回带有这些元素的数组，则表明它背后的设计很糟糕。

500内部服务器错误。第一个参数应该是一个数组
