Question

我在控制器中从某种形式得到两个参数：

$productIds = $this->getRequest()->getParam('productId');
$productQtys = $this->getRequest()->getParam('qty');

结果：

[productId] => Array(
               [0] => 106
               [1] => 107
               [2] => 108
               [3] => 109
               )    
[qty] => Array(
               [0] => 4
               [1] => 3
               [2] => 2
               [3] => 1
              )

好，现在我想进入每个循环一个productId和qty

我测试了它适用于产品，但我无法获得数量：

foreach($productIds as $prod) {
    //some code...
    $product = Mage::getModel('catalog/product')
                     ->setStoreId(Mage::app()->getStore()->getId())
                     ->load($prod);
    $cart->addProduct($product->getId(), $qty) // here how i get the $qty of each product, if i put it manually it works, 2 for exemple, it add 2 for all products

}

Answer 1

array_combine($productIds,$productQtys)

结果：

array(
       [1639] => 6
       [1640] => 4
       [1641] => 3
       [1646] => 2
)

Answer 2

如果您的密钥是对应的，那么您可以将foreach扩展为key =＆gt;值构造。然后你可以直接在qty数组中使用key。没有测试它，但在这里：

foreach($productIds as $key => $prod) {

    $product = Mage::getModel('catalog/product')
                     ->setStoreId(Mage::app()->getStore()->getId())
                     ->load($prod);
    $cart->addProduct($product->getId(), $qty[$key]) 
}

通过一个循环获取两个数据
