如果当前输入等于数组中的值(带有输入文本的复选框),则Laravel validate required\ U

我有一张有复选框列表的表格。最后一个显示“其他”,单击时,将启用输入文本。

如您所知,复选框存储在一个数组中。

这里是 options_list.blade.php 查看:

@section('content')
    @if($errors->any())
        <div class="alert alert-danger" role="alert">
            <strong><i class="fas fa-exclamation-triangle"></i>&nbsp;Warning</strong>: The following errors have been found:
            <ul>
                @foreach($errors->all() as $error)
                    <li>{{ $error }}</li>
                @endforeach
            </ul>
        </div>
    @endif
    <div class="card">
        <div class="card-body">
            <div class="shadow p-3 mb-5 bg-white rounded">{{--Referencias: https://getbootstrap.com/docs/4.1/utilities/shadows/--}}
                <p class="h6">
                    Here goes the question text
                </p>
                <p class="text-primary">You can choose up to three options</p>
            </div>
            <div class="shadow">
                <form action="{{ route('survey1.post',$token) }}" method="post" id="myForm">
                    <div class="col-lg">
                        @foreach($lineasdeinvestigacion as $lineadeinvestigacion)
                            <div class="custom-control custom-checkbox my-1 mr-sm-2">
                                <input type="checkbox" class="custom-control-input" id="customControlInline{{ $loop->index + 1 }}" name="lineasdeinvestigacion[]" value="{{ $lineadeinvestigacion->linea }}" {{ old('lineasdeinvestigacion') && in_array($lineadeinvestigacion->linea,old('lineasdeinvestigacion')) ?

'checked' : '' }}>
                                <label class="custom-control-label" for="customControlInline{{ $loop->index + 1 }}">{{ $lineadeinvestigacion->linea }}</label>
                            </div>
                        @endforeach
                            <div class="custom-control custom-checkbox my-1 mr-sm-2">
                                <input type="checkbox" class="custom-control-input" id="customControlInlineOtro" name="lineasdeinvestigacion[]" value="other" {{ old('lineasdeinvestigacion') && in_array('other',old('lineasdeinvestigacion')) ?

                                <label class="custom-control-label" for="customControlInlineOtro">Other</label>
                                <input placeholder="" type="text" class="form-control form-control-sm" id="fortalecer_otro" name="fortalecer_otro" maxlength="255" value="{{ old('fortalecer_otro') ? old('fortalecer_otro') : '' }}" disabled>
                            </div>
                            @include('path.to.partials.buttons._continue'){{-- includes @csrf --}}
                    </div>
                </form>
            </div>
        </div>
    </div>
@endsection

这里是 optionsController.php :

public function store(Token $token, Request $request){

        //dd($request->lineasdeinvestigacion);

        //Validating input data
        $this->validate($request,[
            'lineasdeinvestigacion'  =>  'nullable|max:3',
            'fortalecer_otro'        =>  'required_if:lineasdeinvestigacion.*,other|max:255',
        ],[
            'lineasdeinvestigacion.max' => 'You cannot choose more than :max options.',
        ]);
}

dd($request->lineasdeinvestigacion); ):

array:4 [▼
  0 => "Procesos socio-culturales"
  1 => "Ciencia, Innovación tecnológica y Educación"
  2 => "Nuevas formas de movilidad"
  3 => "other"
]

#fortalecer_otro 要空,当“他者” #customControlInlineOtro 选中复选框选项。

解决方法

我认为一种解决方法是分离数组的最后一项,因为要验证的输入,如果 最后的 项(复选框)具有 other 值,并将其添加为要验证的另一个元素,如中所述 this answer .

this one ,它讨论验证最后一个。在我的例子中,我必须计算项目的数量,然后,指示验证数字x,这将是最后一个项目。。。

我该怎么解决这个问题?有什么想法吗?

我意识到了,多亏了 second link count the number of items in an array ,然后应用 required_if

if($request->lineasdeinvestigacion){
            $otro_item = count($request->lineasdeinvestigacion) - 1;
            echo '<p>"other" is the item: '.$otro_item.'</p>';

        }else{
            echo '<p>Nothing was selected in the checkboxes list</p>';
        }

        //dd($request->lineasdeinvestigacion);

        //Validating input data
        $this->validate($request,[
            'lineasdeinvestigacion'  =>  'nullable|max:3',
            'fortalecer_otro'        =>  'required_if:lineasdeinvestigacion.'.$otro_item.',otro|max:255',
        ],[
            'lineasdeinvestigacion.max' => 'No puede elegir más de :max opciones.',
        ]);

这就成功了。
