表单数组验证Laravel 5.2 - Form array validation Laravel 5.2

Form array validation Laravel 5.2

本文关键字：Laravel 验证数组表单 | 更新日期: 2023-09-27

我目前正忙于解决这个问题。我是Laravel和MVC框架的新手。我正在努力创建一个动态表单，让用户能够添加尽可能多的表单。当用户第一次进入页面时，它会生成5个表单字段。以下是迄今为止我的代码。

<div id ={{$id = "from".$i}} >

  <div  class="form-group col-md-6">

                  <div  class="col-md-6   form-group">
                        <label for={{$id = "Address".$i}}>Address</label>
                        <input type="text" name = "address[{{$i}}]" class="form-control" id={{$id = "Address".$i}} placeholder="Street Address"> <!-- problem form array how does this work in laravel --> 

                </div>

                  <div  class="form-group col-md-6">
                         <label for={{$id = "city".$i}}>City</label>
                         <input type="text" value = "{{ old('city') }}" class="form-control" id={{$id = "City".$i}} placeholder="City">
                            @if ($errors->has('city'))
                                <span class="help-block">
                                    <strong>{{ $errors->first('city') }}</strong>
                                </span>
                            @endif
              </div>

我该如何在Laravel 5.2中使用阵列验证表单

这是我的控制器

  public function Postdata(Request $request) { 
             $this->validate($request->all(), [
                'address.*' => 'required|string',
               'city' => 'required',
                  ]);
               }

我正在使用for循环来动态生成表单。

这是我得到的错误

      ErrorException in ValidatesRequests.php line 49:
      Argument 1 passed to App'Http'Controllers'Controller::validate() must be                    an instance of Illuminate'Http'Request, array given, called in           
  C:'wamp'www'Dynamic- 1.0'app'Http'Controllers'propContoller.php on line 34 and defined

有人能帮我或给我指个正确的方向吗？谢谢！

添加name="city[{{$i}}]"
使用php artisan make创建特定请求：request PostRequest
将public function Postdata(Request $request) {更改为public function Postdata(PostRequest $request) {
从控制器中删除验证函数调用
转到/app/Http/Requests/PostRequest.php
然后将规则函数编辑为这样

/**
 * Get the validation rules that apply to the request.
 *
 * @return array
 */
public function rules()
{
    $rules = [];
    foreach($this->request->get() as $key => $val)
    {
        $rules['address.' . $key] = 'required';
        $rules['city.' . $key] = 'required';
    }
    return $rules;
}

谢谢你，伙计！这就是我最终使用的解决方案

  <div  class="form-group col-md-6">

                  <div  class="col-md-6   form-group">
                        <label for={{$id = "Address".$i}}>Address</label>
                        <input type="text"  name="address[{{$i}}]" class="form-control" id={{$id = "Address".$i}} placeholder="Street Address">

                </div>

在帖子请求中，我做了这个

public function authorize()
{
    return true;
}
      /**
        * Get the validation rules that apply to the request.
        *
        * @return array
       */
    public function rules() {
    $rules = [];
       foreach($this->request->get('address') as $key => $val) {
       $rules['address.'.$key] = 'required';
       }
       return $rules;
      }
