Form array validation Laravel 5.2

Question

I am currently stuck on solving this problem. I am new to Laravel and the MVC framework. I am struggling to create the dynamic form that gives the user the ability to add as many forms as possible. When the user enters the page at first it generates 5 form fields . Here is a look at my code so far.

<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>

How would I go about validating a form in Laravel 5.2 with from array

here's my controller

  public function Postdata(Request $request) { 

             $this->validate($request->all(), [
                'address.*' => 'required|string',
               'city' => 'required',
                  ]);

               }

I am using a for loop to generate the forms dynamically.

here is the error I get

      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

Can someone please help or point me in the right direction thank you !

Also it is better to define validation rules in your custom request — Ramil Amerzyanov

add name="city[{{$i}}]"
Create a specific request with php artisan make:request PostRequest
Change public function Postdata(Request $request) { to public function Postdata(PostRequest $request) {
Remove the validate function call from your controller
Go to /app/Http/Requests/PostRequest.php
Then edit the rules function to something like this ...

.

/**
 * 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;
}

Thank You man ! this is the solution I end up with

  <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>

in post request i did this

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;
      }
