前台下单，使用多个coupon。
需要修改三个地方的代码
D:\www\lollicupStore2\app\code\local\Lollicupstore\Multiplecoupon\controllers\CartController.php
1.重新购物车控制器里面的方法、
<?php
/**
* Created by PhpStorm.
* User: lollicup
* Date: 2019/7/18
* Time: 15:05
*/
require_once 'Mage/Checkout/controllers/CartController.php';
class Lollicupstore_Multiplecoupon_CartController extends Mage_Checkout_CartController
{
/**
* Initialize coupon
*/
public function couponPostAction()
{
/**
* No reason continue with empty shopping cart
*/
if (!$this->_getCart()->getQuote()->getItemsCount()) {
$this->_goBack();
return;
}
$couponCode = (string) $this->getRequest()->getParam('coupon_code');
$couponArray= array_unique(explode(',',$couponCode));
if(in_array('TOSFREE',$couponArray)){
$this->_getSession()->addError(
$this->__('Coupon code "%s" is not valid.', Mage::helper('core')->escapeHtml($couponCode))
);
$this->_goBack();
return;
}
$couponCode = implode('',$couponCodeArray);
if ($this->getRequest()->getParam('remove') == 1) {
$couponCode = '';
}
$oldCouponCode = $this->_getQuote()->getCouponCode();
if (!strlen($couponCode) && !strlen($oldCouponCode)) {
$this->_goBack();
return;
}
try {
$codeLength = strlen($couponCode);
$isCodeLengthValid = $codeLength && $codeLength <= Mage_Checkout_Helper_Cart::COUPON_CODE_MAX_LENGTH;
// Combine multiple coupons
$couponFlag = true;
if ($isCodeLengthValid) {
$del = ',';
if ($oldCouponCode) {
if ($oldCouponCode == $couponCode) {
$couponCode = $oldCouponCode;
} else {
$couponCode = $oldCouponCode . $del . $couponCode;
}
}
} else {
$couponCode = '';
}
$this->_getQuote()->getShippingAddress()->setCollectShippingRates(true);
$this->_getQuote()->setCouponCode($couponCode)
->collectTotals()
->save();
if ($codeLength) {
if ($isCodeLengthValid && $couponFlag) {
$this->_getSession()->addSuccess(
$this->__('Coupon code "%s" was applied.', Mage::helper('core')->escapeHtml($couponCode))
);
} else {
$this->_getSession()->addError(
$this->__('Coupon code "%s" is not valid.', Mage::helper('core')->escapeHtml($couponCode))
);
}
} else {
$this->_getSession()->addSuccess($this->__('Coupon code was canceled.'));
}
} catch (Mage_Core_Exception $e) {
$this->_getSession()->addError($e->getMessage());
} catch (Exception $e) {
$this->_getSession()->addError($this->__('Cannot apply the coupon code.'));
Mage::logException($e);
}
$this->_goBack();
}
}2. 重新下单的控制器（重写控制器的方法）
D:\www\lollicupStore2\app\code\local\Amasty\Scheckout\controllers\OnepageController.php
<?php
/**
* @author Amasty Team
* @copyright Copyright (c) 2019 Amasty (https://www.amasty.com)
* @package Amasty_Scheckout
*/
require_once 'Mage/Checkout/controllers/OnepageController.php';
class Amasty_Scheckout_OnepageController extends Mage_Checkout_OnepageController
{
const MESSAGE_TYPE_SUCCESS = 'success';
const MESSAGE_TYPE_ERROR = 'error';
public function couponPostAction(){
$response = array(
"html" => array(
"coupon" => array(
"message" => NULL,
"output" => NULL
)
)
);
$message = '';
$messageType = self::MESSAGE_TYPE_SUCCESS;
$output = &$response["html"]["coupon"]["output"];
$messagesBlock = $this->getLayout()->getMessagesBlock();
$couponCode = (string) $this->getRequest()->getParam('coupon_code');
$couponArray= array_unique(explode(',',$couponCode));
if(in_array('TOSFREE',$couponArray)){
$messageType = self::MESSAGE_TYPE_ERROR;
$message = $this->__('Coupon code "%s" is not valid.', Mage::helper('core')->escapeHtml($couponCode));
}else {
if ($this->getRequest()->getParam('remove') == 1) {
$couponCode = '';
}
$oldCouponCode = $this->getOnepage()->getQuote()->getCouponCode();
if (!strlen($couponCode) && !strlen($oldCouponCode)) {
} else {
$this->_reloadRequest();
try {
$codeLength = strlen($couponCode);
$isCodeLengthValid = $codeLength && $codeLength <= 255;
$this->getOnepage()->getQuote()->getShippingAddress()->setCollectShippingRates(true);
$this->getOnepage()->getQuote()->setCouponCode($isCodeLengthValid ? $couponCode : '')
->collectTotals()
->save();
if ($codeLength) {
if ($isCodeLengthValid && $couponCode == $this->getOnepage()->getQuote()->getCouponCode()) {
$message = $this->__('Coupon code "%s" was applied.', Mage::helper('core')->escapeHtml($couponCode));
} else {
$messageType = self::MESSAGE_TYPE_ERROR;
$message = $this->__('Coupon code "%s" is not valid.', Mage::helper('core')->escapeHtml($couponCode));
}
} else {
$message = $this->__('Coupon code was canceled.');
}
$output = $this->_getCouponHtml();
$this->getOnepage()->getQuote()->setTotalsCollectedFlag(false);
$this->getOnepage()->getQuote()->collectTotals();
$this->getOnepage()->getQuote()->save();
$response["html"]["review"] = $this->_getReviewHtml();
$response["html"]["shipping_method"] = $this->_getShippingMethodsHtml();
$response["html"]["payment_method"] = $this->_getPaymentMethodsHtml();
$response["html"]["base_grand_total_updated"] = $this->getQuoteBaseGrandTotal();
$response["html"]["is_ampromo_active"] = $this->isAmpromoEnable();
} catch (Mage_Core_Exception $e) {
$message = $e->getMessage();
$messageType = self::MESSAGE_TYPE_ERROR;
} catch (Exception $e) {
$message = $this->__('Cannot apply the coupon code.');
$messageType = self::MESSAGE_TYPE_ERROR;
Mage::logException($e);
}
}
}
if ($this->isAmpromoEnable()) {
Mage::getSingleton('core/session')->{'add' . ucfirst($messageType)}($message);
}
$messagesBlock->{'add' . ucfirst($messageType)}($message);
$response["html"]["coupon"]["message"] = $messagesBlock->toHtml();
$this->getResponse()->setBody(Mage::helper('core')->jsonEncode($response));
}
?>3.最后是计算coupon的总价。直接重写model

4. 添加config.xml配置文件
