如何在产品视图页面中添加从购物车中删除产品的选项？

Answer 1

要通过sku从购物车中删除商品，您可以使用以下代码

创建控制器

$sku = 'xyz';
$cartHelper = Mage::helper('checkout/cart');
$items = $cartHelper->getCart()->getItems();
foreach ($items as $item) {
    if ($item->getProduct()->getSku() == $sku) {
        $cartHelper->getCart()->removeItem($item->getItemId())->save();     
        break;
    }
}

然后在您的产品视图页面上，您可以创建一个发布要删除的sku的ajax /按钮

请参阅Magento - Remove Item from Cart by Sku

创建：app / code / local / MagePal / DeleteCartItemBySku / etc / config.xml

<?xml version="1.0"?>
<config>
    <modules>
        <MagePal_DeleteCartItemBySku>
            <version>0.0.1</version>
        </MagePal_DeleteCartItemBySku>
    </modules>
    <frontend>
        <routers>
            <checkout>
                <use>standard</use>
                <args>
                    <modules>
                        <MagePal_DeleteCartItemBySku after="Mage_Checkout">MagePal_DeleteCartItemBySku</MagePal_DeleteCartItemBySku>
                    </modules>
                </args>
            </checkout>
        </routers>
    </frontend>

    <global>
        <models>
            <deletecartitembysku>
                <class>MagePal_DeleteCartItemBySku_Model</class>
            </deletecartitembysku>
        </models>
    </global>
</config>

创建：app / code / local / MagePal / DeleteCartItemBySku / controllers / CartController.php

<?php   
  require_once Mage::getModuleDir('controllers', 'Mage_Checkout') . DS . 'CartController.php';
  //require_once 'Mage/Checkout/controllers/CartController.php';

  class MagePal_DeleteCartItemBySku_CartController extends Mage_Checkout_CartController
  {
    public function removeItemBySkuAction()
    {
        $sku = $this->getRequest()->getParam('sku');
        $cartHelper = Mage::helper('checkout/cart');
        $items = $cartHelper->getCart()->getItems();

        $found = false;
        foreach ($items as $item) {
            if ($item->getProduct()->getSku() == $sku) {
                $cartHelper->getCart()->removeItem($item->getItemId())->save();  
                $found = true;   
                break;
            }
        }

        $message = ($found) ? "Item {$sku} Removed" : "Item {$sku} Not Found";
        Mage::getSingleton('core/session')->addSuccess($message);
        //Mage::getSingleton('core/session')->addError($message);

        $this->_redirectReferer();
    }
  }

＆GT？;

创建：app / etc / modules / MagePal_DeleteCartItemBySku.xml

  <?xml version="1.0"?>
    <config>
           <modules>
                  <MagePal_DeleteCartItemBySku>
                          <active>true</active>
                          <codePool>local</codePool>
                  </MagePal_DeleteCartItemBySku>
           </modules>
    </config>

然后你的ajax / button url：

domain.com/checkout/cart/removeItemBySku/sku/xyz
