Magento中获取购物车项目的两个命令之间的区别 [英] Difference between two commands of fetching Shopping Cart Items in Magento

问题描述

在Magento中，如果您需要获取/获取购物车的商品详细信息，则可以通过两种可能的方式中的任何一种来完成，这将为您提供阵列中所有已购物商品:

In Magento, if you need to get / fetch the Shopping Cart's Item details, you can do it in any of the two possible ways, which will provide you with all the shopped Items in an array:-

1. $ cartItems1 = $ cart-> getQuote()-> getAllItems();
2. $ cartItems2 = $ cart-> getItems()-> getData();

但是在使用以上两种方法中的任何一种之前，您需要将购物车对象初始化为:-

But before using any one of the above two methods, you need to initialize the shopping cart object as:-

$cart = new Mage_Checkout_Model_Cart();
$cart->init();

任何人都可以详细说明这两个选项提供的内容吗?彼此之间的差异以及可能的用法.

Magento中提供了更多此类选项，任何人都可以突出显示它吗?

推荐答案

如果您查看购物车和Quote类的代码，一切将变得清晰.

If you look at the code of the Cart and Quote classes everything will become clear.

这是$ cart-> getItems()的代码:

Here's the code for $cart->getItems():

public function getItems()
{
  return $this->getQuote()->getAllVisibleItems();
}

简单明了-它仅调用Quote对象的方法.所以现在的问题是: getAllVisibleItems()和 getAllItems()有什么区别?

Plain and simple - it just calls a method of the Quote object. So the question now is: What is the difference between getAllVisibleItems() and getAllItems()?

让我们看一下这两种方法的代码:

Let's look at the code of both methods:

public function getAllItems()
{
    $items = array();
    foreach ($this->getItemsCollection() as $item) {
        if (!$item->isDeleted()) {
            $items[] =  $item;
        }
    }
    return $items;
}

public function getAllVisibleItems()
{
    $items = array();
    foreach ($this->getItemsCollection() as $item) {
        if (!$item->isDeleted() && !$item->getParentItemId()) {
            $items[] =  $item;
        }
    }
    return $items;
}

唯一的区别: getAllVisibleItems()对每个项目都有一个附加检查:

The only difference: getAllVisibleItems() has an additional check for each item:

!$item->getParentItemId()

测试产品是否有父产品(换句话说，它测试它是否是简单产品).因此，与 getAllItems()相反，此方法的return数组将缺少简单的乘积.

which tests if the product has a parent (in other words, it tests if it is a simple product). So this method's return array will be missing simple products, as opposed to getAllItems().

还有其他检索项目的方法吗?

一种方法是直接从quote对象获取产品集合:

One would be to directly get the product collection from the quote object:

$productCollection = $cart->getQuote()->getItemsCollection();
