Alter Request parameter(Email) and then Authenticate User in Laravel - php

Question

I need to change the request parameter i.e. email, and then attempt login with the new email.
What I am trying:
$user_handle = $request->email;
$gook = Gookarma::where('handle', '=', $user_handle)->firstOrFail();
$acc = Account::find($gook->karmable_id);
$request->email = $acc->email;
if ($this->attemptLogin($request)) {
return $this->sendLoginResponse($request);
}
But it doesn't update the request, and login attempt goes with the previous email field input.
Previous email I'm pulling up from API.
I tried with request->all() but when attempt login after the request update, it displays an error.

Answer 1

You could try something like this:
$request->merge(['email' => $acc->email]);

Answer 2

you can use merge method :
$request->merge([
'email' =>$acc->email,
]);
or you can build an array to replace the entire request input like:
$arrayToReplace=$request->all();
$arrayToReplace['email']=$acc->email;
and then use replace method:
$request->replace($arrayToReplace);
if neither of the above ways did not work, try making a request your self:
$array=$request->all();
$array['email']=$acc->email;
$req = new Request([$array]);
then use the new request for your operations.

Answer 3

Creating a new variable of Request instance and assigning email and password from the previous request variable to the new variable worked for me.
$req = new Request([$request]);
$req['email']=$acc->email;
$req['password'] = $request->password;
