Laravel cast Request to different Request - validation

Question

I have a three different forms that submit to the same controller in Laravel. Each form has its own validation rules stored in a Request. Here's an example of my code:
public function store($id, $type, Request $request)
{
switch ($type) {
case 'daily':
$this->monthly($id, $type, $request);
break;
case 'monthly':
$this->monthly($id, $type, $request);
break;
case 'yearly':
$this->yearly($id, $type, $request);
}
return redirect(route('x.show', $id));
}
private function monthly($id, $type, MonthlyFormRequest $request)
{
//store form
}
However, this doesn't work and throwns an instance error since Request isn't the same type as MonthlyFormRequest in the monthly method. Is there a way to cast the Request to MonthlyFormRequest or is there some other way to do it? I prefer to avoid declaring validation rules in the controller itself. What would be the best way to get a uniform Request type request in the store method and then use MonthlyFormRequest?

Answer 1

You could pass the type trough a request parameter and move the switch case to your request and preform the check there as such:
In your request:
public function rules()
{
switch($this->type){
case 'dailty':
return [
'field': 'required'
];
break;
case 'monthly':
return [
'field': 'required'
];
break;
case 'yearly':
return [
'field': 'required'
];
break;
}
}
In your Controller:
public function store($id, YourCustomRequest $request)
{
return redirect(route('x.show', $id));
}
