I have my custom Request, which extends the Backpack CrudController.
Now I would like to override the prepareForValidation of the ValidatesWhenResolvedTrait since it looks like the right place to modify my incoming data, but I can't figure out how ...
So my first question is, can I override this method? Its protected ...
protected function prepareForValidation()
And my second question, how can I modify my input on the Request or FormRreuqest objects?
Here is my RequestClass
<?php
namespace App\Http\Requests;
use App\Http\Requests\Request;
use Config;
class DonationsRequest extends \Backpack\CRUD\app\Http\Requests\CrudRequest
{
/**
* Determine if the user is authorized to make this request.
*
* #return bool
*/
public function authorize()
{
// only allow updates if the user is logged in
return \Auth::check();
}
/**
* Get the validation rules that apply to the request.
*
* #return array
*/
public function rules()
{
return [
'name' => 'required|max:255',
'email' => 'required|email',
'dob' => 'required|date',
'newsletter' => 'required|boolean',
'country' => 'sometimes|required|in:'.implode(',', Config::get('validation.countries')),
'street' => 'sometimes|required|string|max:255',
'zip' => 'sometimes|required|string|between:4,5',
'city' => 'sometimes|required|string|between:4,255',
'amount' => 'required|numeric|between:1,'.Config::get('donations.max'),
'type' => 'required|in:oo,monthly',
'provider' => 'sometimes|string|nullable',
'product_id' => 'sometimes|exists:products,id|nullable',
'campaign_id' => 'required|exists:campaigns,id',
'status' => 'sometimes|required|in:pending,canceled,success,error',
'profile' => 'sometimes|string|regex:/^profile[0-9]+$/|nullable',
];
}
/**
* Get the validation attributes that apply to the request.
*
* #return array
*/
public function attributes()
{
return [
//
];
}
/**
* Get the validation messages that apply to the request.
*
* #return array
*/
public function messages()
{
return [
//
];
}
private function prepareForValidation()
{
dd('getValidatorInstance custom');
$this->sanitizeInput();
return parent::getValidatorInstance();
}
private function sanitizeInput()
{
dd('sanitizeInput custom');
$data = $this->all();
dd($data);
// overwrite the newsletter field value to match boolean validation
$data['newsletter'] = ($data['newsletter'] == 'true' || $data['newsletter'] == '1' || $data['newsletter'] == true) ? true : false;
return $data;
}
private function validate() {
dd('validate');
}
}
As you can see, I first tried to override the getValidatorInstance method, since this looked like the common aproach to this, but it is not executed (so not overridden - protected?).

Answer 1

Although I didn't tried but it seems it should work you can override validationData from Illuminate\Foundation\Http\FormRequest class like.
/**
* Get data to be validated from the request.
*
* #return array
*/
protected function validationData()
{
$all = parent::validationData();
//e.g you have a field which may be json string or array
if (is_string($playerIDs = array_get($all, 'player_id')))
$playerIDs = json_decode($playerIDs, true);
$all['player_id'] = $playerIDs
return $all;
}
or you can override all method in Illuminate\Http\Concerns\InteractsWithInput trait
/**
* Get all of the input and files for the request.
*
* #return array
*/
public function all()
{
$all = parent::all();
//then do your operation
if (is_string($playerIDs = array_get($all, 'player_id')))
$playerIDs = json_decode($playerIDs, true);
$all['player_id'] = $playerIDs
return $all;
}

Answer 2

Could you modify the request?
$request->merge(['field' => 'new value']);

Answer 3

Well I am sure,this can help in modifying The input, it worked for me.[laravel 5.4]
place this
$input['url'] = $url;
$this->replace($input);
dd($input);
in listFormRequest. (use $all instead of $input, if you follow above used answer).
This only changes input,which is available even in controller. You still need to find a way to insert it into DB, or do something else to use modified input for using it in blade.

Ok I found out where the error was. I did split the Frontend Request and the Backend Request Call. Since I was working on the Backend Request the Frontend Request was not overwriting anything ... so it was my bad, no bug there, sry for the waste of time, but a big thanks to the community!
