如何循环Magento集合?
基本上,我需要获取我的客户的CSV文件,每天在脚本中自动生成。 我尝试了几种方法,但它们太慢或实际上已经耗尽内存。如何循环Magento集合?
* 1)通过收集资源*
$collection = Mage::getResourceModel('customer/customer_collection')
->addAttributeToSelect('email')
->addAttributeToSelect('created_at')
->joinAttribute('billing_company', 'customer_address/company', 'default_billing', null, 'left')
->joinAttribute('billing_street', 'customer_address/street', 'default_billing', null, 'left')
->joinAttribute('billing_postcode', 'customer_address/postcode', 'default_billing', null, 'left')
->joinAttribute('billing_telephone', 'customer_address/telephone', 'default_billing', null, 'left')
->joinAttribute('billing_city', 'customer_address/city', 'default_billing', null, 'left')
->joinAttribute('billing_region', 'customer_address/region', 'default_billing', null, 'left')
->joinAttribute('billing_country_id', 'customer_address/country_id', 'default_billing', null, 'left');
foreach($collection as $customer) {
echo $customer->getFirstname() . ",";
}
2)的foreach和负载客户
$collection = Mage::getResourceModel('customer/customer_collection');
foreach($collection as $customer) {
$fullcustomer = Mage::getModel("customer/customer")->load($customer->getId());
echo $fullcustomer->getFirstname() . ",";
}
任何想法的foreach?
谢谢!
在每个Customer对象上使用load()
将显着减少减慢您的代码。我建议你添加所需的属性集合的第一种方法是正确的,但像完成它:
$collection->toArray([$arrRequiredFields = array()]);
这样一来,个人客户不会被装载,但toArray()
(doco here)将给你你想要的字段,然后你可以迭代多维数组来产生你的逗号分隔的字符串。
或者,您可以尝试$collection->toXml()
并使用XML,如果您对此感到满意。 Google会将您指向xml-> csv转换方法。
恐怕我得到了空白页面用尽了内存.. 。 – 2010-09-29 16:32:51
尝试分页大集合!
这个想法是,如果你可以加载更小的块集合,你将不会使用尽可能多的内存。 加载一个块(页面),然后对其进行处理,如将其保存到文本文件中,然后加载下一个块。结果是,你已经与整个较大的集合一起工作,但只会产生最大页面的内存成本。
我们使用类似的东西来从我们的商店导出订单。 我插入你的收藏,它似乎工作。
<?php
if(php_sapi_name()!=="cli"){
echo "Must be run from the command line.";
};
/**
* Setup a magento instance so we can run this export from the command line.
*/
require_once('app/Mage.php');
umask(0);
if (!Mage::isInstalled()) {
echo "Application is not installed yet, please complete install wizard first.";
exit;
}
// Only for urls // Don't remove this
$_SERVER['SCRIPT_NAME'] = str_replace(basename(__FILE__), 'index.php', $_SERVER['SCRIPT_NAME']);
$_SERVER['SCRIPT_FILENAME'] = str_replace(basename(__FILE__), 'index.php', $_SERVER['SCRIPT_FILENAME']);
Mage::app('admin')->setUseSessionInUrl(false);
Mage::setIsDeveloperMode(true); ini_set('display_errors', 1); error_reporting(E_ALL);
try {
Mage::getConfig()->init();
Mage::app();
} catch (Exception $e) {
Mage::printException($e);
}
ini_set('memory_limit','500M');
$customerCount = 0;
try{
//configure the collection filters.
$collection = Mage::getResourceModel('customer/customer_collection')
->addAttributeToSelect('email')
->addAttributeToSelect('created_at')
->joinAttribute('billing_company', 'customer_address/company', 'default_billing', null, 'left')
->joinAttribute('billing_street', 'customer_address/street', 'default_billing', null, 'left')
->joinAttribute('billing_postcode', 'customer_address/postcode', 'default_billing', null, 'left')
->joinAttribute('billing_telephone', 'customer_address/telephone', 'default_billing', null, 'left')
->joinAttribute('billing_city', 'customer_address/city', 'default_billing', null, 'left')
->joinAttribute('billing_region', 'customer_address/region', 'default_billing', null, 'left')
->joinAttribute('billing_country_id', 'customer_address/country_id', 'default_billing', null, 'left');
//Add a page size to the result set.
$collection->setPageSize(100);
//discover how many page the result will be.
$pages = $collection->getLastPageNumber();
$currentPage = 1;
//This is the file to append the output to.
$fp = fopen('/tmp/customers.csv', 'w');
do{
//Tell the collection which page to load.
$collection->setCurPage($currentPage);
$collection->load();
foreach ($collection as $customer){
//write the collection array as a CSV.
$customerArray = $customer->toArray();
//var_dump($customerArray); echo "\n\n";
fputcsv($fp, $customerArray);
$customerCount++;
}
$currentPage++;
//make the collection unload the data in memory so it will pick up the next page when load() is called.
$collection->clear();
} while ($currentPage <= $pages);
fclose($fp);
} catch (Exception $e) {
//$response['error'] = $e->getMessage();
Mage::printException($e);
}
echo "Saved $customerCount customers to csv file \n";
?>
我救它作为exportCustomers.php。
然后设置你的cron任务运行: PHP -f /path/to/your/magento/exportCustomers.php
这两项解决方案似乎可行,但双方似乎特别优化。你能否用这两种方法解决问题,以便我们可以告诉你在找什么? – 2010-09-24 13:35:55
尝试在Magento中使用资源迭代器。看到这个职位:http://stackoverflow.com/questions/7419886/using-magentos-resource-iterator-model-on-a-product-collection – awaage 2012-09-15 02:27:06
