Laravel：Blade foreach 循环 bootstrap 列

发布于01月14日

我有一个foreach循环，内部包含带有 bootstrap 列的html.

@foreach($address as $add)
    <div class="col-md-6">
        Some data
    </div>
@endforeach

However, bootstrap requires the row div before creating columns, placing that straight in to the foreach loop would create a row div for each col-md-6. I want to know how I can throw in the row div, skip the next loop throwing in only the closing div tag. And then repeat that process.

循环4次的输出示例:

<div class="row">
    <div class="col-md-6">
        Some data
    </div>
    <div class="col-md-6">
        Some data
    </div>
</div>
<div class="row">
    <div class="col-md-6">
        Some data
    </div>
    <div class="col-md-6">
        Some data
    </div>
</div>

推荐答案

作为Alexey Mezenin答案的替代，你可以使用array_chunk.http://php.net/manual/en/function.array-chunk.php

@foreach(array_chunk($address, 2) as $chunk)
    <div class="row">
        @foreach($chunk as $add)
            <div class="col-md-6">
                Some data
            </div>
        @endforeach
    </div>
@endforeach

我个人觉得上面的内容更具可读性.

Alternatively, if $address is a collection you could do $address->chunk(2) instead of array_chunk($address, 2).

如果你想改变你拥有的列的数量，你只需要改变2列的数量.
