如何使用自定义输入字段将产品“添加到购物车”并将其保存到数据库？

9

我创建了一个自定义模块，在其中重写了产品页面上的“ 添加到购物车”表单，并成功使用catalog_product_view.xml文件完成了此操作。现在，我可以在产品页面的前视图上看到一个自定义输入字段，但是我需要将该字段的值与数量，价格等一起发布到数据库中，然后在订单历史记录中再次检索它。

我搜索了一段时间，也成功地在quote_item＆sales_order表中创建了新的自定义列。（根据我的信息，添加到购物车条目quote_item和结帐到sales_order表后的订单。如果我对此有误，请在此方面也进行纠正，因为我仍然是学习者。）

我尝试了很多并进行了搜索，但没有找到相关的解决方案。我的供应商名称为Cloudways，模块名称为Mymodule。以下是我的模块的文件：

我所需要做的就是发布自定义输入字段的值，并将其与订单一起保存在数据库中。提前致谢！

看看这个magento 1示例stackoverflow.com/questions/9412074 / ... ...您应该能够使用“ additional_options”来使用观察者github.com/magento/magento2/…来存储此信息... ...使用Additional_options会自动在管理员，销售订单电子邮件等中显示此信息
— Renon Stewart
您为什么不使用带有自定义选项的简单产品来完成此任务？
— 雷诺·斯图尔特
@RS我需要以编程方式执行此操作，因为我们将使用不同的自定义选项进一步扩展此自定义购物车，我认为这只能通过自定义模块完成。
— Fayyaz Khattak
您可以在代码中添加一个（github）链接吗，所以我可以下载并尝试实现
— Additional_options
@RS是的，请给我几分钟。

为此，您可以使用magento内置的“ additional_options”功能，这样就不必编辑电子邮件模板，管理订单视图，客户订单视图（等）来显示自定义选项。

class CheckoutCartProductAddAfterObserver implements ObserverInterface
{

    protected $_request;

    /**
     * @param RequestInterface $request

    public function __construct(RequestInterface $request){
            $this->_request = $request;

}

方法1-使用Observer将Option从quote_item复制到order_item参见Magento 2 fieldset.xml; 将字段从报价复制到订单

/app/code/Cloudways/Mymodule/Observer/SalesModelServiceQuoteSubmitBeforeObserver.php

<?php

namespace Cloudways\Mymodule\Observer;

use Magento\Framework\Event\Observer as EventObserver;
use Magento\Framework\Event\ObserverInterface;


class SalesModelServiceQuoteSubmitBeforeObserver implements ObserverInterface
{

    private $quoteItems = [];

    private $quote = null;
    private $order = null;

    /**
     * Add order information into GA block to render on checkout success pages
     *
     * @param EventObserver $observer
     * @return void
     */
    public function execute(EventObserver $observer)
    {

        $this->quote = $observer->getQuote();
        $this->order = $observer->getOrder();

        // can not find an equivalent event for sales_convert_quote_item_to_order_item


        /* @var  \Magento\Sales\Model\Order\Item $orderItem */
        foreach($this->order->getItems() as $orderItem){
            if(!$orderItem->getParentItemId() && $orderItem->getProductType() == \Magento\Catalog\Model\Product\Type::TYPE_SIMPLE){

                if($quoteItem = $this->getQuoteItemById($orderItem->getQuoteItemId())){
                    if ($additionalOptionsQuote = $quoteItem->getOptionByCode('additional_options')) {

                        //To do
                        // - check to make sure element are not added twice
                        // - $additionalOptionsQuote - may not be an array
                        if($additionalOptionsOrder = $orderItem->getProductOptionByCode('additional_options')){
                            $additionalOptions = array_merge($additionalOptionsQuote, $additionalOptionsOrder);
                        }
                        else{
                            $additionalOptions = $additionalOptionsQuote;
                        }


                        if(count($additionalOptions) > 0){
                            $options = $orderItem->getProductOptions();
                            $options['additional_options'] = unserialize($additionalOptions->getValue());
                            $orderItem->setProductOptions($options);
                        }

                    }
                }
            }
        }

    }


    private function getQuoteItemById($id){
        if(empty($this->quoteItems)){
            /* @var  \Magento\Quote\Model\Quote\Item $item */
            foreach($this->quote->getItems() as $item){

                //filter out config/bundle etc product
                if(!$item->getParentItemId() && $item->getProductType() == \Magento\Catalog\Model\Product\Type::TYPE_SIMPLE){
                    $this->quoteItems[$item->getId()] = $item;
                }
            }
        }


        if(array_key_exists($id, $this->quoteItems)){
            return $this->quoteItems[$id];
        }

        return null;
    }
}

方法2-使用插件将Option从quote_item复制到order_item

/app/code/Cloudways/Mymodule/etc/di.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">

        <plugin name="cloudways_mymodule\_Sales_Quote_Item_ToOrderItem" type="Cloudways\Mymodule\Plugin\QuoteItemToOrderItemPlugin" />
    </type>
</config>

/app/code/Cloudways/Mymodule/Plugin/QuoteItemToOrderItemPlugin.php

<?php

namespace Cloudways\Mymodule\Plugin;

class QuoteItemToOrderItemPlugin
{

    public function aroundConvert(\Magento\Quote\Model\Quote\Item\ToOrderItem $subject, callable $proceed, $quoteItem, $data)
    {

        // get order item
        $orderItem = $proceed($quoteItem, $data);


        if(!$orderItem->getParentItemId() && $orderItem->getProductType() == \Magento\Catalog\Model\Product\Type::TYPE_SIMPLE){
            if ($additionalOptionsQuote = $quoteItem->getOptionByCode('additional_options')) {
                //To do
                // - check to make sure element are not added twice
                // - $additionalOptionsQuote - may not be an array
                if($additionalOptionsOrder = $orderItem->getProductOptionByCode('additional_options')){
                    $additionalOptions = array_merge($additionalOptionsQuote, $additionalOptionsOrder);
                }
                else{
                    $additionalOptions = $additionalOptionsQuote;
                }
                if(count($additionalOptions) > 0){
                    $options = $orderItem->getProductOptions();
                    $options['additional_options'] = unserialize($additionalOptions->getValue());
                    $orderItem->setProductOptions($options);
                }
            }
        }

        return $orderItem;

}

购物车和管理员订单查看页面

@renon我为简单的产品尝试了上述功能，效果很好，谢谢！但我需要相同的可配置产品，但在购物车页面“所选选项或它们的组合当前不可用”时出现以下错误。我知道为什么会出现此问题，但是有什么方法可以克服它，我的意思是过滤掉特定的选项？
— Nausif
刚刚使用它，它就像一个魅力。谢谢！您是否知道Magento中确实允许每个项目（而不是每个产品）属性的任何功能？例如，衬衫上的自定义文字，但同时有多个相同衬衫的文字不同。Magento现在将这些产品合并到购物车中，因此我丢失了每个商品的真正特定设置。
— 尔根
@Nausif，我遇到了同样的问题，但是现在解决了。请参考这个网址- magento.stackexchange.com/questions/177133/...
— 基肖尔长谷
@renon我使用它，值显示在微型购物车，购物车和结帐栏中。我有可配置的产品可以执行此操作。我尝试了两种Quote转换方法，但值未在admin中的订单邮件和订单部分显示。
— Rishabh Rk Rai
如果有人[invalidargumentexception] unable to unserialize value.使用json_encode和json_decode而不是序列化和反序列化

解决此问题的方法：//用相同的选项值创建新的购物车项目将添加一个新的行项目，而不是增加前一个项目的数量

我在Magento \ Quote \ Model \ Quote \ Item中为方法representProduct的插件添加了。在插件中，我检查它是否是我所需的其他参数，以及是否返回所需的结果（true）。
