这段代码将使用自定义集合，并使用网格通过Magento的后端（adminhtml）打印文件列表，以便下载或删除。
问题是集合在添加项目（$dataCollection->addItem（$dataObject））后多次重复，结果相同。
建议？
谢谢

发生的情况是，您每次都向集合中添加相同的对象。您需要为每个文件创建一个唯一的Varien_Object。在foreach循环中创建$dataObject，如下所示：
//$dataObject = new Varien_Object();
foreach ($flocal->ls() as $item) {
$dataObject = new Varien_Object();
$dataObject->addData(
array(
'filename' => $item['text'],
'size' => $item['size'],
'date_modified'=> $item['mod_date']
)
);
$dataCollection->addItem($dataObject);
d($dataObject);
}
