Form array validation Laravel 5.2 - php

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 !

Answer 1

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;
}
