本文介绍了Symfony 3 在我的结帐时正确获取价格和名称的问题的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我的购物车有问题.我是编码新手，我无法正确处理这些东西.所以.我的问题是:

我创建了一个网上商店"，其中包含:产品列表/购物车/结帐.

有 2 个产品:当我将它们添加到我的卡片时，我得到了:然后是结帐出错的地方:您可以看到它添加了 ID 为 3 的产品的名称和价格，而不是正确添加了这两个项目.

这是我的代码:

CartController(带结账功能)

set('cart', '');$session = $this->get('request_stack')->getCurrentRequest()->getSession();$cart = $session->get('cart', array());//$cart = $session->get('cart', array());//$cart = array_keys($cart);//print_r($cart);死;//使用购物车中的查询和 ID 获取信息if( $cart != '' ) {$em = $this->getDoctrine()->getEntityManager();foreach( $cart as $id => $quantity ) {$product[] = $em->getRepository('TuinadviesBundle:Product')->findById($id);}if(!isset($product)){return $this->render('TuinadviesBundle:cart:index.html.twig', array('空' =>真的，));}return $this->render('TuinadviesBundle:Cart:index.html.twig', array('产品' =>$产品，));} 别的 {return $this->render('TuinadviesBundle:Cart:index.html.twig', array('空' =>真的，));}}/*** @Route("/checkout", name="cart_checkout")*/公共功能结帐(){$session = $this->get('request_stack')->getCurrentRequest()->getSession();$cart = $session->get('cart', array());foreach( $cart as $id => $qunatity) {$em = $this->getDoctrine()->getEntityManager();$product = $em->getRepository('TuinadviesBundle:Product')->find(key($cart));}$em = $this->getDoctrine()->getEntityManager();$product = $em->getRepository('TuinadviesBundle:Product')->find(key($cart));return $this->render('@Tuinadvies/checkout/index.html.twig', array('产品' =>$产品，'价格' =>$product->getPrice(),'名称' =>$product->getName(),转储($产品)，));//return $this->render('@Tuinadvies/checkout/index.html.twig', array(//'产品' =>$产品();//));//return $this->render('@Tuinadvies/checkout/index.html.twig', array(//'id' =>$product->getId(),//'价格' =>$product->getPrice(),//));}/*** @Route("/add/{id}", name="cart_add")*/公共函数 addAction($id){//获取购物车$em = $this->getDoctrine()->getEntityManager();$product = $em->getRepository('TuinadviesBundle:Product')->find($id);//print_r($product->getId());死;$session = $this->get('request_stack')->getCurrentRequest()->getSession();$cart = $session->get('cart', array());//$cart = $session->get('cart', array());//检查 $id 是否已经存在于其中.如果 ( $product == NULL ) {$this->get('session')->setFlash('notice', '该产品在商店不可用');返回 $this->redirect($this->generateUrl('cart'));} 别的 {if( isset($cart[$id]) ) {//$qtyAvailable = $product->getQuantity();$qtyAvailable = 999;if( $qtyAvailable >= $cart[$id] + 1 ) {$cart[$id] = $cart[$id] + 1;} 别的 {$this->get('session')->setFlash('notice', '数量超过可用库存');返回 $this->redirect($this->generateUrl('cart'));}} 别的 {//如果它没有使它成为 1$cart = $session->get('cart', array());$cart[$id] = $id;$cart[$id] = 1;}$session->set('cart', $cart);返回 $this->redirect($this->generateUrl('cart'));}}/*** @Route("/remove/{id}", name="cart_remove")*/公共函数 removeAction($id){//检查购物车$session = $this->get('request_stack')->getCurrentRequest()->getSession();$cart = $session->get('cart', array());//$cart = $session->get('cart', array());//如果它不存在，则重定向到购物车索引页面.结尾if(!$cart) { $this->redirect( $this->generateUrl('cart') );}//检查 $id 是否已经存在于其中.if( isset($cart[$id]) ) {//如果是 ++ 数量$cart[$id] = '0';未设置($cart[$id])；//echo $cart[$id] ;死();} 别的 {返回 $this->redirect( $this->generateUrl('cart') );}$session->set('cart', $cart);//重定向(索引页)返回 $this->redirect( $this->generateUrl('cart') );}}

可能有很多意大利面条式代码(错误代码)，但那是因为我是一个真正的新手.非常抱歉！！！

希望任何人都可以帮助我:)

干杯

解决方案

看起来您正在从数据库中获取每个已检出的产品，然后在 $product 变量上覆盖它而不是保存所有这些.

您应该使用数组来存储不同的产品，然后使用这些产品来填充树枝模板中的值

因此，在您的结帐操作中，您会看到如下内容:

$em = $this->getDoctrine()->getEntityManager();$repo = $em->getRepository('TuinadviesBundle:Product');$产品 = [];foreach ($cart as $id => $quantity) {$products[] = $repo->find($id);}

然后，在渲染模板时，只需传递 $products 数组，而不是名称和价格.

return $this->render('@Tuinadvies/checkout/index.html.twig', array('产品' =>$产品，));

最后，在您的树枝模板中，您将遍历 products 数组并使用它的 id 来获取正确的数量，而不是遍历购物车

{% for product in products %}<td><b>{{product.name }}</b></td><td>{{product.id }}</td><td>{{cart[product.id]}}</td><td>{{product.price }}</td></tr>{% 结束为 %}

希望这会有所帮助！

I am having trouble with my shopping cart. I'm a newbie at coding and i can not get this stuff right. So. my problem is:

I made a "webshop" with a: product list / shopping cart / checkout.

There are 2 products: When i add them to my card i get this: And then there is the checkout where it goes wrong: You can see that it added the name and the price of the product with the ID 3 instead of adding both items correctly.

Here is my code:

CartController (with the checkout function)

There might be a lot of spaghetti code (bad code) but that's because i'm a real newbie. so sorry about that!!!

Hope anyone can help me :)

解决方案

It looks like you're fetching every checked out product from the database but overwriting it then on the $product variable instead of saving all of them.

You should use an array to store the different products and then use those products to fill the values in your twig template

So, in your checkout action you would have something like this:

$em = $this->getDoctrine()->getEntityManager();
$repo = $em->getRepository('TuinadviesBundle:Product');

$products = [];
foreach ($cart as $id => $quantity) {
    $products[] = $repo->find($id);
}

Then, when rendering the template, just pass the $products array instead of the name and price.

return $this->render('@Tuinadvies/checkout/index.html.twig', array(
    'products' => $products,
));

And finally, in your twig template, instead of iterating over the cart, you would iterate over the products array and use it's id to get the right quantity

{% for product in products %}
    <tr class="col-span-6">
        <td><b>{{ product.name }}</b></td>
        <td>{{ product.id }}</td>
        <td>{{ cart[product.id] }}</td>
        <td>{{ product.price }}</td>
    </tr>
{% endfor %}

Hope this helps!
