Magento 2：如何在观察者中获取报价产品ID？

编程问答 2022-08-14

问题描述

产品ID未显示，并通过此错误** {“ 0”：“警告：为foreach（）提供的参数无效**，请帮我解决这个问题。

如果属性代码不等于5431，我想在这里返回。

那怎么可能。

<?PHP

namespace Softadroit\Prescription\Observer;

use Magento\Framework\Event\ObserverInterface;
use \Magento\Framework\Event\Observer as EventObserver;
use Psr\Log\LoggerInterface;

class Orderplaceafter implements ObserverInterface
{
    protected $_responseFactory;
    protected $_url;

    public function __construct(
        \Magento\Framework\App\ResponseFactory $responseFactory,\Magento\Framework\UrlInterface $url
    ) {
        $this->_responseFactory = $responseFactory;
        $this->_url = $url;
    }
    
    public function execute(\Magento\Framework\Event\Observer $observer)
    {       
        $event = $observer->getEvent();
        $objectManager = \Magento\Framework\App\ObjectManager::getInstance();
        $_checkoutSession = $objectManager->create('\Magento\Checkout\Model\Session');
        $_quoteFactory = $objectManager->create('\Magento\Quote\Model\QuoteFactory');
        
        //$quote = $block->getQuoteData();
        /* $quote= $observer->getEvent()->getQuote();
        $item = $quote->getAllVisibleItems();
        foreach($item  as $_item){
        echo $_item->getProduct()->getId(); */
        
        $event = $observer->getEvent();
        //$item = $event->getQuoteItem();
        foreach($event->getQuoteItem()  as $_item){
        $product = $objectManager->create('Magento\Catalog\Model\Product')->load($_item->getProductId());
                
        $is_priscription = $product->getData('prescription');
        if($is_priscription != '5431'){
                return;
            }
        }
        
        if ($quote->getId()) {
            $quote->setIsActive(1)->setReservedOrderId(null)->save();
            $_checkoutSession->replaceQuote($quote);
            $url = $this->_url->getUrl('prescription/index'); //('[ModuleName]/[ModuleName]/[[Action]');
            $this->_responseFactory->create()->setRedirect($url)->sendResponse();
            die();
        }
    }
}

我们非常感谢您的帮助

预先感谢！

下一步

这是我更新的代码，我在这里获取产品ID，现在我想如果产品属性选项ID不等于5431，然后重定向到成功页面，即（订单成功），并且如果oroduct选项ID等于5431，然后重定向到下面定义的网址（处方/索引）

<?PHP

namespace Softadroit\Prescription\Observer;

use Magento\Framework\Event\ObserverInterface;
use Magento\Framework\Controller\ResultFactory;
use \Magento\Framework\Event\Observer as EventObserver;
use Magento\Framework\App\ObjectManager;
use Psr\Log\LoggerInterface;

class Orderplaceafter implements ObserverInterface
{
    protected $_responseFactory;
    protected $_url;
    protected $_order;

    public function __construct(
        \Magento\Framework\App\ResponseFactory $responseFactory,\Magento\Framework\UrlInterface $url,\Magento\Sales\Api\Data\OrderInterface $order
    ) {
        $this->_responseFactory = $responseFactory;
        $this->_url = $url;
        $this->_order = $order;
    }
    
    public function execute(\Magento\Framework\Event\Observer $observer)
    {       
        $event = $observer->getEvent();
        $objectManager = \Magento\Framework\App\ObjectManager::getInstance();
        $_checkoutSession = $objectManager->create('\Magento\Checkout\Model\Session');
        $_quoteFactory = $objectManager->create('\Magento\Quote\Model\QuoteFactory');
                    
        $orderid = $observer->getEvent()->getorderIds();
        $order = $this->_order->load($orderid);
        
        foreach($order->getItemsCollection() as $_item){        
        $product = $_item->getProductId();  
        
        //echo $_item->getName(); die();
        
        $is_priscription =  $_item->getProduct()->getMyCustomAttribute('prescription'); 
        
        
        if($is_priscription != '5431'){
        
            $resultRedirect = $this->resultFactory->create(ResultFactory::TYPE_REDIRECT);
            $resultRedirect->setPath('order-success');
            return $resultRedirect;
            }
        }
        
        $order = $_checkoutSession->getLastRealOrder();
        $quote = $_quoteFactory->create()->loadByIdWithoutStore($order->getQuoteId());
        
        if ($quote->getId()) {
            $quote->setIsActive(1)->setReservedOrderId(null)->save();
            $_checkoutSession->replaceQuote($quote);
            $url = $this->_url->getUrl('prescription/index'); //('[ModuleName]/[ModuleName]/[[Action]');
            $this->_responseFactory->create()->setRedirect($url)->sendResponse();
            die();
        }
    }
}

解决方法

如果您正在观察事件checkout_onepage_controller_success_action，则没有直接访问报价的权限。只给订单。而且您也无法从Checkout会话实例中获取它，因为在调度事件之前，已从会话中删除了报价。
但是您可以通过订单获取报价。

您将需要首先添加报价存储库作为对观察者的依赖

private $quoteRepository;
public function __construct(
    \Magento\Quote\Api\CartRepositoryInterface $quoteRepository,....
) {
    $this->quoteRepository = $quoteRepository;
    ....
}

然后，在execute方法中，您可以执行此操作

$order = $observer->getOrder();
$quoteId = $order->getQuoteId();
$quote = $this->qupteRepository->get($quoteId);
if ($quote && $quote->getId()) {
    $items = $quote->getAllItems();
    //loop through items ....
}

这将为您提供尝试要做的事情。
但是我认为一个更好的主意是不要使用报价和产品来获得所需的东西。
将产品属性值添加到购物车后，应将其保存在报价单上，然后将其转换为通过报价单创建的订单项。
这样，在观察者中，您可以执行$order = $observer->getOrder()，然后遍历订单项$order->getAllItems()并检查所需内容。

请尝试以下操作：

<?php

namespace Softadroit\Prescription\Observer;

use Magento\Framework\Event\ObserverInterface;
use \Magento\Framework\Event\Observer as EventObserver;
use Psr\Log\LoggerInterface;

class Orderplaceafter implements ObserverInterface
{
    protected $_responseFactory;
    protected $_url;

    public function __construct(
        \Magento\Framework\App\ResponseFactory $responseFactory,\Magento\Framework\UrlInterface $url,\Magento\Quote\Model\QuoteRepository $quoteRepository,\Magento\Sales\Model\OrderFactory $orderFactory,\Magento\Checkout\Model\Session $checkoutSession
    ) {
        $this->_responseFactory = $responseFactory;
        $this->_url = $url;
        $this->quoteRepository = $quoteRepository;
        $this->orderFactory = $orderFactory;
        $this->checkoutSession = $checkoutSession;
    }
    
    public function execute(\Magento\Framework\Event\Observer $observer)
    {       
        $event = $observer->getEvent();

        $orderIds = $observer->getEvent()->getOrderIds();
        $order = $this->orderFactory->create()->load($orderIds[0]);

        $quote = $this->quoteRepository->get($order->getQuoteId());
        
        $item = $quote->getAllItems();

        foreach($item  as $_item){
        $product = $_item->getProduct();
                
        $is_priscription = $product->getData('prescription');
        if($is_priscription != "" && $is_priscription == '5431'){
                return;
            }
        }
        
        if ($quote->getId()) {
            $quote->setIsActive(1)->setReservedOrderId(null)->save();
            $this->checkoutSession->replaceQuote($quote);
            $url = $this->_url->getUrl('prescription/index'); 
            $this->_responseFactory->create()->setRedirect($url)->sendResponse();
            die();
        }
    }
}

之后，请运行 php bin / magento setup：upgrade
