Laravel 4 reset password - php

Question

I copied an example from the laravel documentation:
public function postResetPassword() {
$credentials = array('email' => Input::get('email'));
return Password::reset($credentials, function($user, $password) {
$user->password = Hash::make($password);
$user->save();
return Redirect::to('/');
});
}
But it seems that returning Redirect::to('/') doesn't work, because instead of home page I get an error which tells that controller method is not found.
But if I write the code this way:
$credentials = array('email' => Input::get('email'));
Password::reset($credentials, function($user, $password) {
$user->password = Hash::make($password);
$user->save();
});
return Redirect::back();
It works, though I can't understand how do I get session flash variables (actually I get them).
Another question is where are the rules about password length (6 chars) are written? Can I change them?

Answer 1

To answer why your first code example doesn't work is because if your look at your app/routes.php file you should see something along the lines of Route::get('/', 'HomeController#index');. The part that comes before the # symbol is the name of your controller while the part after it is the method that is being called in your controller when the route is requested. Make sure that method is defined.
After looking at the following. I think you should put the redirect inside of the closure you give as a return statement.
Then how you retrieve data that has been flashed to the session after redirecting the user you use the following Session::get('key');.
For your last question look at the following documentation.
Example:
$validator = Validator::make(
array('email' => Input::get('email'), 'password' => Input::get('password'), 'password_confirm' => Input::get('password_confirm')),
array('email' => 'required|unique:users,email|email', 'password' => 'required|min:3|max:20|same:password_confirm')
);
The second array passed is where you can modify the rules for the validator.

Answer 2

To answer your second question regarding changing the rules for password validation.
The Password facade extends PasswordBroker.php which has this function on line 208:
/**
* Set a custom password validator.
*
* #param \Closure $callback
* #return void
*/
public function validator(Closure $callback)
{
$this->passwordValidator = $callback;
}
Therefore, to override the default password validator, simply make this call from your controller:
Password::validator(function(){
//validator in here
});
