使用 laravel 验证方法验证循环内的多个 select 框

Question

我有多个 select 框在一个表单的循环内具有相同的名称。我添加了 laravel 验证来检查 select 框 select 是否被编辑。但是所有 select 框都显示验证错误消息。请检查所附图片。任何帮助，将不胜感激。

cart.blade.php

@forelse($carts as $key => $cart)
<div class="col-sm-4 col-sm-4-booking1 form-group {{ $errors->has('guest.*.sleeps') ? ' has-error' : '' }}">
    <label>Sleep(s)</label>

    <select class="form-control form-control-booking1 jsBookCalSleep"  name="guest[{{ $cart->_id }}][sleeps]">
    <option value="">Choose Sleep(s)</option>
    @for($i = 1; $i <= 30; $i++)
       <option value="{{ $i }}" @if($i == $cart->sleeps) selected @endif>{{ $i }}</option>
    @endfor
    </select>

    @if ($errors->has('guest.*.sleeps'))
         <span class="help-block"><strong>{{ $errors->first('guest.*.sleeps') }}</strong></span>
    @endif
</div> 
@empty
  <p>No bookings in your cart</p>
@endforelse

CartController.php

public function store(CartRequest $request)
{
    dd($request->all());
}

CartRequest.php

public function rules()
    {
        return [
            'guest.*.sleeps' => 'required|not_in:0'
        ];
    }

Answer 1

试试这些

@php
 $inputName='guest.'.$cart->_id.'.sleeps';
@endphp
@if ($errors->has($inputName))
     <span class="help-block"><strong>{{ $errors->first($inputName) }}</strong></span>
@endif

我没有测试过，如果不工作让我知道
