Laravel Blade - Header＆amp;页面中的页脚

Question

我有按类别排序的数据：

$( document ).on( "click", "#formSubmit", function() {
  console.log( 'Button Clicked' );
});

我喜欢用刀片打印它

Category 1, Product 1, Amount
Category 1, Product 2, Amount
Category 2, Product 3, Amount 

Answer 1

我假设$ categories是带索引类别，产品和数量的已排序多维数组。

   @for ($i = 0; $i < count($categories) ; $i++)
         <?php $category_product_toatl=0; ?>
         {{ $categories[$i]['category'] }}
         {{ $categories[$i]['product'] }}     {{ $categories[$i]['amount']}}
         <?php 
              $category_product_total= $category_product_total+ $categories[$i]['amount'];
         ?>
         @for ($j = $i+1; $j < count($categories) ; $j++)
              @if($categories[$i]['category']== $categories[$j]['category'])
                     {{ $categories[$j]['product'] }}     {{ $categories[$j]['amount']}}
                     <?php 
                          $category_product_total= $category_product_total+ $categories[$j]['amount']; 
                     ?>
               @else
                     break;
               @endif

        @endfor
   Total Amount of {{ $category[$i] }} : {{ $category_product_total }}
@endfor
