$userdata = array(
'email' => Input::get('email'),
'password' => Input::get('password')
);
if (Auth::attempt($userdata)) {
echo 'SUCCESS!';
} else {
return Redirect::to('login');
}
when i run the application from browser i got this error :
Argument 1 passed to Illuminate\Auth\EloquentUserProvider::validateCredentials() must be an instance of Illuminate\Auth\UserInterface, instance of User given, called in /home/srtpl17/Sites/yatin.sr/vendor/laravel/framework/src/Illuminate/Auth/Guard.php on line 316 and defined
What have I done incorrectly?
回答1:
It sounds like from your error that your User model does not implement UserInterface (the default User Model that comes with Laravel does this properly, so I'm guessing you made a custom one)
http://github.com/laravel/laravel/blob/master/app/models/User.php
Make sure that the User model looks like this:
use Illuminate\Auth\UserInterface;
use Illuminate\Auth\Reminders\RemindableInterface;
class User extends Eloquent implements UserInterface, RemindableInterface {
/**
* Get the unique identifier for the user.
*
* @return mixed
*/
public function getAuthIdentifier()
{
return $this->getKey();
}
/**
* Get the password for the user.
*
* @return string
*/
public function getAuthPassword()
{
return $this->password;
}
/**
* Get the e-mail address where password reminders are sent.
*
* @return string
*/
public function getReminderEmail()
{
return $this->email;
}
// Add your other methods here
}

You don't show what userdata is defined as, but from the error message it seems like it's an instance of your User model class.
The Auth::attempt() method is looking for an array of the credentials not a model.

This error might also appear when you use a different model for users (example :member) if it's the case you need to update Authentication Model and Authentication Table in app/config/auth.php with the appropriate model / database table.
