如何在foreach中使用多维数组? [英] How do I use the multidimensional array in foreach?

问题描述

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:

My cart page is something like this:

@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

如何在此代码块中对多维数组值进行垃圾邮件处理.假设有3个乘积，则应该有3行.

How do I spam the multidimentional array values in this block of code. Suppose there are 3 products then there should be 3 rows.

由于product_name和product_description是不同的数组，因此我无法在总行数保持为2的情况下创建foreach，但它会为行的正确名称和正文发送垃圾邮件.

注意:我正在Laravel框架中进行编码，这就是为什么foreach语法似乎不同的原因.

Note: I am coding in Laravel framework that is why foreach syntax seems different.

谢谢！

推荐答案

使用 @for() 遍历数组:

Use @for() to iterate over array:

@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
