如何在 laravel blade 视图中打破 foreach 循环？

Question

我有一个这样的循环：

@foreach($data as $d)
    @if(condition==true)
        {{$d}}
        // Here I want to break the loop in above condition true.
    @endif
@endforeach

如果条件满足，我想在数据显示后打破循环。

如何在 laravel blade 视图中实现？

Answer 1

来自Blade docs：

When using loops you may also end the loop or skip the current iteration:

@foreach ($users as $user)
    @if ($user->type == 1)
        @continue
    @endif

    <li>{{ $user->name }}</li>

    @if ($user->number == 5)
        @break
    @endif
@endforeach

Answer 2

你可以这样破解

@foreach($data as $d)
    @if($d === "something")
        {{$d}}
        @if(condition)
            @break
        @endif
    @endif
@endforeach

Answer 3

Basic usage

默认情况下，blade 没有 @break 和 @continue 这两个有用的东西。所以包括在内。

此外，$loop 变量是在循环中引入的，（几乎）与 Twig 完全一样。

Basic Example

@foreach($stuff as $key => $val)
     $loop->index;       // int, zero based
     $loop->index1;      // int, starts at 1
     $loop->revindex;    // int
     $loop->revindex1;   // int
     $loop->first;       // bool
     $loop->last;        // bool
     $loop->even;        // bool
     $loop->odd;         // bool
     $loop->length;      // int

    @foreach($other as $name => $age)
        $loop->parent->odd;
        @foreach($friends as $foo => $bar)
            $loop->parent->index;
            $loop->parent->parentLoop->index;
        @endforeach
    @endforeach 

    @break

    @continue

@endforeach

Answer 4

@foreach($data as $d)
    @if(condition==true)
        {{$d}}
        @break // Put this here
    @endif
@endforeach

Answer 5

官方文档说：当使用循环时，您也可以使用 @continue 和 @break 结束循环或跳过当前迭代 指令：

@foreach ($users as $user)
@if ($user->type == 1)
    @continue
@endif

<li>{{ $user->name }}</li>

@if ($user->number == 5)
    @break
@endif

@endforeach
