Question

我有一个数组 $ cart ：

array:1 [
  "product" => array:5 [
      "product_id" => array:2 [
      0 => 2
      1 => 6
    ]
    "product_name" => array:2 [
      0 => "HP Core i3 5th Gen - (4 GB/1 TB HDD/DOS) X5Q17PA 15-be005TU Notebook  (15.6 inch, Turbo SIlver, 2.19 kg)"
      1 => "SAMSUNG 55.88cm (22) Full HD LED TV  (UA22F5100AR, 2 x HDMI, 2 x USB)"
    ]
    "product_description" => array:2 [
      0 => "HP Core i3 5th Gen - (4 GB/1 TB HDD/DOS) X5Q17PA 15-be005TU Notebook  (15.6 inch, Turbo SIlver, 2.19 kg)HP Core i3 5th Gen - (4 GB/1 TB HDD/DOS) X5Q17PA 15-be005TU Notebook  (15.6 inch, Turbo SIlver, 2.19 kg)"
      1 => "SAMSUNG 55.88cm (22) Full HD LED TV  (UA22F5100AR, 2 x HDMI, 2 x USB)"
    ]
    "product_image" => array:2 [
      0 => "1481116344.jpeg"
      1 => "1481180186.jpeg"
    ]
    "product_price" => array:2 [
      0 => 350
      1 => 200
    ]
  ]
]

我的购物车页面是这样的：

@foreach()
<div class="row">
  <div class="col-md-2 col-xs-12">
    <img class="img-responsive" src="{{asset('images/150x70.png')}}">
  </div>
  <div class="col-md-4 col-xs-12">
    <h4><strong>Product Name</strong></h4>
    <h4><small>Product Body</small></h4>
  </div>
  <div class="col-md-6 col-xs-12">
    <div class="col-md-6 text-right">
     <h4><strong>$ Price</strong> x</h4>
    </div>
    <div class="col-md-4 col-xs-9">
     <input type="text" class="form-control input-sm" placeholder="quantity">
    </div>
    <div class="col-md-2 col-xs-2">
     <button class="btn btn-danger btn-sm"><span class="glyphicon glyphicon-trash"></span></button>
    </div>
  </div>
</div>
<hr>    
@endforeach

输出看起来像

如何对此代码块中的多维数组值进行垃圾邮件。假设有3个产品，那么应该有3行。

由于product_name和product_description是不同的数组，因此我无法创建一个foreach，其中总行数为2，但是垃圾邮件的行名称和正文是垃圾邮件。

注意：我在Laravel框架中进行编码，这就是为什么foreach语法看起来不同。

谢谢！

使用@for()迭代数组：

@for ($i = 0; $i < count($cart['product']['product_id']); $i++)
    <div class="row">
       <div class="col-md-2 col-xs-12">
           <img class="img-responsive" src="{{ asset('images/150x70.png') }}">
       </div>
       <div class="col-md-4 col-xs-12">
           <h4><strong>{{ $card['product']['product_name'][$i] }}</strong></h4>
           <h4><small>{{ $card['product']['product_description'][$i] }}</small></h4>
       </div>
       <div class="col-md-6 col-xs-12">
           <div class="col-md-6 text-right">
           <h4><strong>$ {{ $card['product']['product_price'][$i] }}</strong> x</h4>
           </div>
           <div class="col-md-4 col-xs-9">
               <input type="text" class="form-control input-sm" placeholder="quantity">
            </div>
            <div class="col-md-2 col-xs-2">
            <button class="btn btn-danger btn-sm"><span class="glyphicon glyphicon-trash"></span></button>
            </div>
        </div>
    </div>
    <hr>    
@endfor

Answer 2

如果product_id是product数组的一致字段，则可以使用其长度作为迭代器计数来对其他键执行查找。警告这假设您用于输出到模板的所有密钥与product_id具有相同的长度，并且每个密钥中的每个索引都指向相同的产品。

您似乎没有quantity的密钥，因此没有填充该字段

<?php for ($i = 0; $i <= count($cart['product']['product_id']); $i++): ?>
    <div class="row">
      <div class="col-md-2 col-xs-12">
        <img class="img-responsive" src="<?php echo $cart['product']['product_image'][$i]; ?>">
      </div>
      <div class="col-md-4 col-xs-12">
        <h4><strong><?php echo $cart['product']['product_name'][$i]; ?></strong></h4>
        <h4><small><?php echo $cart['product']['product_description'][$i]; ?></small></h4>
      </div>
      <div class="col-md-6 col-xs-12">
        <div class="col-md-6 text-right">
         <h4><strong>$ <?php echo $cart['product']['product_price'][$i]; ?></strong> x</h4>
        </div>
        <div class="col-md-4 col-xs-9">
         <input type="text" class="form-control input-sm" placeholder="quantity">
        </div>
        <div class="col-md-2 col-xs-2">
         <button class="btn btn-danger btn-sm"><span class="glyphicon glyphicon-trash"></span></button>
        </div>
      </div>
    </div>
    <hr>    
<?php endfor ?>

PS。不幸的是，我不熟悉Laravel语法，所以这是标准的PHP

修改

因为我没有和我一起使用这种格式我已经创建了一个转换器功能，可以将你的数组变成更易于管理的东西

<?php function convertCartArray($cart){ // create new container array $products = array(); // create array of all the keys in the old cart that you wish to convert $keys = array('product_id', 'product_name', 'product_description', 'product_image', 'product_price'); // for each product for ($i = 0; $i < count($cart['product']['product_id']); $i++){ // create a new product array $product = array(); // for each of the keys for ($j = 0; $j < count($keys); $j++){ // convert old cart product detail over to product detail $product[$keys[$j]] = $cart['product']$keys[$j][$i]; } // add product to productsArray array_push($products, $product); } // return new products array return $products; } $productsArray = convertCartArray($cart); for ($i = 0; $i <= count($productsArray); $i++): ?> <div class="row"> <div class="col-md-2 col-xs-12"> <img class="img-responsive" src="<?php echo $productsArray[$i]['product_image']; ?>"> </div> <div class="col-md-4 col-xs-12"> <h4><strong><?php echo $productsArray[$i]['product_name']; ?></strong></h4> <h4><small><?php echo $productsArray[$i]['product_description']; ?></small></h4> </div> <div class="col-md-6 col-xs-12"> <div class="col-md-6 text-right"> <h4><strong>$ <?php echo $productsArray[$i]['product_price']; ?></strong> x</h4> </div> <div class="col-md-4 col-xs-9"> <input type="text" class="form-control input-sm" placeholder="quantity"> </div> <div class="col-md-2 col-xs-2"> <button class="btn btn-danger btn-sm"><span class="glyphicon glyphicon-trash"></span></button> </div> </div> </div> <hr> <?php endfor ?>

我会像这样重新格式化输入，但你需要的是@foreach($products as $product) $products，无论你当前的变量是什么。

如果您不想更改输入的格式（实际上，我推荐它）请使用Alexey Mezenin的回答

$products = [
    ['id' => '2',
        'name' => 'HP Core i3 5th Gen - (4 GB/1 TB HDD/DOS) X5Q17PA 15-be005TU Notebook  (15.6 inch, Turbo SIlver, 2.19 kg)',
        'description' => 'SAMSUNG 55.88cm (22) Full HD LED TV  (UA22F5100AR, 2 x HDMI, 2 x USB)',
        'image' => '1481116344.jpeg',
        'price' => '350',
    ],
    ['id' => '6',
        'name' => 'HP Core i3 5th Gen - (4 GB/1 TB HDD/DOS) X5Q17PA 15-be005TU Notebook  (15.6 inch, Turbo SIlver, 2.19 kg)HP Core i3 5th Gen - (4 GB/1 TB HDD/DOS) X5Q17PA 15-be005TU Notebook  (15.6 inch, Turbo SIlver, 2.19 kg)',
        'description' => 'SAMSUNG 55.88cm (22) Full HD LED TV  (UA22F5100AR, 2 x HDMI, 2 x USB)',
        'image' => '1481116344.jpeg',
        'price' => '200',
    ]
];



@foreach($products as $product)
    <div class="row">
        <div class="col-md-2 col-xs-12">
            <img class="img-responsive" src="{{asset($product['image'])}}">
        </div>
        <div class="col-md-4 col-xs-12">
            <h4><strong>{{$product['name']}}</strong></h4>
            <h4><small>{{$product['description']}}</small></h4>
        </div>
        <div class="col-md-6 col-xs-12">
            <div class="col-md-6 text-right">
                <h4><strong>${{$product['price']}}</strong> x</h4>
            </div>
            <div class="col-md-4 col-xs-9">
                <input type="text" class="form-control input-sm" placeholder="quantity">
            </div>
            <div class="col-md-2 col-xs-2">
                <button class="btn btn-danger btn-sm"><span class="glyphicon glyphicon-trash"></span></button>
            </div>
        </div>
    </div>
    <hr>
@endforeach
