Laravel-5 merge multi-level form array validation - php

Question

I have a form which I have created in Laravel-5. This form contains input arrays. I have also created a Request file using php artisan make:request ClassRequest. Within my request file, I have added the Laravel validator() function which I use to add additional fields to the form array when the form gets posted.
However, I can't seem to get the form array updated/merged in the way that I would like.
View file:
<input type="text" name="class[0]['location_id']" value="1">
<input type="text" name="class[1]['location_id']" value="2">
Request file (ClassRequest.php):
<?php
namespace App\Http\Requests;
use App\Http\Requests\Request;
use Illuminate\Contracts\Validation\Validator;
use Illuminate\Validation\Factory as ValidatorFactory;
use DB;
class ClassRequest extends Request
{
/**
* Determine if the user is authorized to make this request.
*
* #return bool
*/
public function authorize()
{
return true;
}
/**
* Get the validation rules that apply to the request.
*
* #return array
*/
public function validator(ValidatorFactory $factory)
{
$input = $this->get('class');
foreach($input as $key => $val)
{
$dateInString = strtotime(str_replace('/', '-', $input[$key]['date']));
$this->merge(['class' => [$key => [
'location_id' => $input[$key]['location_id'],
'location' => 'test123'
]
]]);
}
return $factory->make($this->input(), $this->rules(), $this->messages());
}
}
As you can see from the request file above, I am trying to add a new key/value pair to the form array (location => 'test123'). However, only 1 field ever gets posted through to the controller.
Does anyone know the proper way to do this?

Merge function merges given array into collection and any string key in the array matching a string key in the collection will overwrite the value in the collection.So this is why you saw only 1 field posted through to controller.
foreach($input as $key => $val)
{
$this->merge(['class' => [$key => [
'location_id' => $input[$key]['location_id'],
'location' => 'test123'
]
]]);
}
'class' key is overwritten in each iteration and only last one persist.So the only item is last one.
$input = $this->get('class');
foreach($input as $key => $val)
{
$another[$key]['location_id']=$input[$key]["'location_id'"];
$another[$key]['location']='123';
}
$myreal['class']=$another;
$this->merge($myreal);
return $factory->make($this->input(), $this->rules(), $this->messages());
If you are getting error related with location id then try this
public function validator(ValidatorFactory $factory)
{
$input = $this->get('class');
foreach($input as $key => $val)
{
foreach($input[$key] as $v){
$another[$key]['location_id']=$v;
$another[$key]['location']='124';
}
}
$myreal['class']=$another;
$this->merge($myreal);
return $factory->make($this->input(), $this->rules(), $this->messages());
}
