在Laravel Blade中查找foreach循环的最后一次迭代
问题描述:
在刀片模板中,我使用last()方法查找foreach循环的最后一次迭代:
In blade template i use last() method to find last iteration of foreach loop:
@foreach ($colors as $k => $v)
<option value={!! $v->id !!} {{ $colors->last()->id==$v->id ? 'selected':'' }} > {!! $v->name !!} </option>
@endforeach
可以吗?也许有Laravel风格的方法可以做到这一点?
Is it ok? Perhaps there is a Laravel-style way to do the same?
答
对于Laravel 5.3+,您可以使用 $ loop 变量
As for Laravel 5.3+, you can use the $loop variable
$loop->last
@foreach ($colors as $k => $v)
@if($loop->last)
// at last loop, code here
@endif
@endforeach
