我有这个方法,我首先检索一个Varien_Data_Collection,然后我通过addItem()从另一个Varien_Data_Collection中逐个添加项目:
protected function _prepareCollection(){
$productId = $this->getRequest()->getParam('id');
$websiteId = 0;
if ($store = $this->getRequest()->getParam('store')) {
$websiteId = Mage::app()->getStore($store)->getWebsiteId();
$collection = Mage::getModel('productalert/stock')
->getCustomerCollection()
->join($productId, $websiteId);
foreach ($collection as $item) {
$item->setData('is_customer', 'Sì');
}
$guestCollection = Mage::getModel('productsalert/gueststock')->getCollection()
->addFieldToFilter("product_id", $productId)
->addFieldToFilter("website_id", $websiteId);
foreach ($guestCollection as $guestItem) {
$obj = new Mage_Customer_Model_Customer();
$obj->setData($guestItem->getData());
$obj->setData('alert_stock_id', ($guestItem->getData('alert_stock_id')+100000000));
$obj->setData('email', $guestItem->getData('guest_email'));
$obj->setData('is_customer', 'No');
$collection->addItem($obj);
}
$collection = $collection->setOrder('add_date','ASC');
$this->_sortCollectionDescByDate($collection);
$this->setCollection($collection);
}
else{
$this->setCollection(new Varien_Data_Collection());
}
return parent::_prepareCollection();
}
所以,当我有最终的集合时,我想设置顺序,因为其中的项目有一个共同的属性(' add_date'),所以我设置了setOrder方法,但它没有#t; t工作(IRC上的soemone告诉我setOrder修改了查询)。所以我可以手动完成,但是我觉得在添加项目后没有订购集合似乎很奇怪。我看了一下Varien_Data_Collection API,但是我没有看到任何可以帮助我的东西。我还尝试将集合类更改为Varien_Data_Collection_Db并设置addOrder()方法,但没有任何更改。
任何想法?
谢谢!

答案 0 :(得分:1)
你可以打电话
$collection->clear();
$collection->....//here you add some logic for ordering;
$collection->load();//here collection with new filters will be loaded.
OR
您可以在最后一条消息中使用某种排序功能,例如指定的here。
