Question

我在查看：

上有这个

..
...
<div class="section group">
    @foreach ($product as $item)
    <div class="grid_1_of_4 images_1_of_4">
        <h4><a href="#">{!! $item->name !!}</a></h4>
        <div class="price-details">
            <div class="price-number">
                <p><span class="price">$ {!! $item->price !!} </span></p>
            </div>
            <div class="add-cart">                              
                <h4><a href="#">More Info</a></h4>
            </div>
            <div class="clear"></div>
        </div>                           
    </div>         
    @endforeach
</div>
...
..

这是控制器：

..
...
public function index(){
    $product = product::paginate(8);
    return view('shop.index', compact('product'));
}
...
..

我想显示八数据我将控制器分为两部分，因此输出将如下：

<div class="section group">
    <div class="grid_1_of_4 images_1_of_4">
        <h4><a href="#">item 01</a></h4>
        <div class="price-details">
            <div class="price-number">
                <p><span class="price">$ price 01 </span></p>
            </div>
            <div class="add-cart">

            <div class="clear"></div>
        </div>

    <div class="grid_1_of_4 images_1_of_4">

        </div>                           
    </div>
</div>

我认为它应该使用嵌套循环，但我不知道如何在laravel中编写它。

任何人都知道应该怎么做？

Answer 1

http://laravel.com/api/5.1/Illuminate/Database/Eloquent/Collection.html#method_chunk

我喜欢chunk（）函数。比array_chunk更具可读性和可重用性

@foreach ($product->chunk(4) as $chunkedProducts)
<div class="section group">
@foreach ($chunkedProducts as $item)
<div class="grid_1_of_4 images_1_of_4">
    <h4><a href="#">{!! $item->name !!}</a></h4>
    <div class="price-details">
        <div class="price-number">
            <p><span class="price">$ {!! $item->price !!} </span></p>
        </div>
        <div class="add-cart">                              
            <h4><a href="#">More Info</a></h4>
        </div>
        <div class="clear"></div>
    </div>                           
</div>         
@endforeach
</div>
@endforeach

Answer 2

This question正在解决一个非常类似的问题，请看一下。

引用：

您可以在$ product-＆gt; all（）上使用array_chunk将其拆分为4个组，然后创建一个嵌套的@foreach。

在这种情况下，它可能看起来像这样（未经测试！）：

@foreach (array_chunk($product->all(), 4) as $productSection)
    <div class="section group">
        @foreach ($productSection as $item)
            <div class="grid_1_of_4 images_1_of_4">
                <h4><a href="#">{!! $item->name !!}</a></h4>
                <div class="price-details">
                    <div class="price-number">
                        <p><span class="price">$ {!! $item->price !!} </span></p>
                    </div>
                    <div class="add-cart">                              
                        <h4><a href="#">More Info</a></h4>
                    </div>
                    <div class="clear"></div>
                </div>                           
            </div>
        @endforeach
    </div>
@endforeach
