How to validate inputs from GET request in Laravel

I wanted to validate inputs from a GET request without using the

this->validate($request... or \Validator::make($request...

and prefer to do it like

$input = $request->validate([... rules ...]);

however since get requests doesn't have $request parameters how can I achieve it?

public function sampleGet($param1, $param2) {

     // How can I pass the $param1 and $param to to validate?
     $input = $request->validate([
         'param1' => 'required',
         'param2' => 'required  
     ]);
}

If you want all the route parameters you can get them as an array:

$request->route()->parameters()

Since you already have those parameters being passed to your method you can just build an array with them:

compact('param1', 'param2');
// or
['param1' => $param1, 'param2' => $param2];

You are not going to be using the validate method on the Request though, you will have to manually create a validator. Unless you want to merge this array into the request or create a new request with these as inputs.

There is nothing special about the validate method on a Controller or on a Request. They are all making a validator and validating the data the same way you would yourself.

When manually creating a validator you still have a validate method that will throw an exception, which would be the equivalent to what is happening on Request and the Controller with their validate methods.

You can do so and it will have same behavior as validate

validator($request->route()->parameters(), [

    'param1' => 'required',
    'param2' => 'required'
    ....

])->validate();

You can do like that.

public function getData(Request $request)
{
  try {
       $input['route1'] = $request->route('route1');
       $input['route2'] = $request->route('route2');
       $valid = Validator::make($input, [
            'route1' => 'required',
            'route2' => 'required'
         ]);
  } catch (\Throwable $th) {
    echo "<pre>";print_r($th->__toString());die;
  }
}
