Get a user by username and password with Laravel - php

Question

I need to do some extra checks on a user, I would like to get the user by username and password.
Firstly:
Is there a built in function that gets a user by username and password without authenticating them?
Secondly:
If the above is no, then how do I correctly hash the password, because if I use Hash::make( $password ) and then compare to the database, it is not the same... You would usually use Hash::check but I need to actually get the user by username and password.

Answer 1

In Laravel 5.2
You can use Auth::once($credentials) to validate credentials and thereafter Auth::getUser(); to get the user.
$credentials = Request::only('username', 'password');
if(!Auth::once($credentials)) {
// Invalid user credentials; throw Exception.
}
$user = Auth::getUser();

Answer 2

First:
If you want to check if user data to authentication is correct you can use:
if (Auth::validate($credentials))
{
//
}
But if you want to get user from database with user and password, you can use:
$user = User::whereName($username)->wherePassword(Hash::make($password))->first();
Second
To store password in database you should use Hash::make($password) as you showed and it works without any problems. Using Auth::validate should solve the issue.

Answer 3

Yes, there is a built in function you should use. I recommend you to read the docs. But here's a good example, it's pretty self-evident:
$input = array(
'username' => Input::get('username'),
'password' => Input::get('password'),
);
$remember = (boolean)Input::get('remember'); //'Remember me' checkbox
if (Auth::attempt($input, $remember)) {
return Redirect::intended('dashboard')->with("success", "You're logged in!"); //Redirect the user to the page intended to go to, with the dashboard page as default
}
Registering a user looks something like this:
$input = array(
'username' => Input::get('username'),
'email' => Input::get('email'),
'password' => Hash::make(Input::get('password')) //Encrypt password
);
$user = User::create($input);
I also recommend you to read about input validation. I hope this helps, good luck.
Edit: I didn't read the "without authenticating them" part. You should use Auth::validate($input) as Marcin already explained.

Answer 4

Laravel 5.7
To check a users credentials without logging them in, I had to do this:
$user = User::whereEmail($request->email)->first();
$user = password_verify($request->password, optional($user)->getAuthPassword()) ? $user : false;
Laravel auth validation makes use of https://www.php.net/manual/en/function.password-verify.php
