如何访问php Magento中的数组值？

您好，这是

打印结果的一部分（$this->Product）

：

    [_oldFiel

dsMap:protected] => Array
            (
                [stock_status_changed_automatically] => stock_status_changed_auto
                [use_config_enable_qty_increments] => use_config_enable_qty_inc

                [use_config_enable_qty_inc] => use_config_enable_qty_increments
            )
    )

如您所见，有2个['qty']值。如果我键入：

---

$this->Product['stock_item']['qty']=2

；我可以访问第一个['qty']。我的问题是如何访问第二个['qty']？Thx

Magento为任何“数据”提供了神奇的getter和setter，因此您可以这样做来获取和设置“数量”：

$qty = $this->product->getQty();
$this->product->setQty($qty);

但您也可以使用以下方法获取阵列：

$dataArray     = $this->product->getData();
$origDataArray = $this->product->getOrigData();

$this->product->setData($dataArray);
$this->product->setOrigData($origDataArray);

或通过以下方式获取/设置特定值：

$dataQty     = $product->getData('qty');
$origDataQty = $product->getOrigData('qty');

$product->setData('qty', $dataQty);
$product->setOrigData('qty', $origDataQty);

---

他们来自不同的地方

data

和

origData

您所说的不同属性是什么意思？

[\u data:protected]=>Array（[qty]=>2

和

[\u origData:protected]=>Array（[qty]=>0.0000

似乎由主键/objectok的两个不同键控制，但我如何访问它呢？：D@RoyalBg你能邀请我聊天吗？
