$user = new User;
$user->firstname = Input::get('firstname');
$user->lastname = Input::get('lastname');
$user->email = Input::get('email');
$user->password = Hash::make(Input::get('password'));
$user->save();
return Redirect::to('users/login')->with('message', 'Thanks for registering!');

<div class="login-body">
<h2>SIGN IN</h2>

{{ Form::text('email', null, array('class'=>'input-block-level', 'placeholder'=>'Email Address', 'data-rule-required'=>'true' ,'data-rule-email'=>'true')) }}
</div>
</div>
<div class="control-group">
<div class="pw controls">

<input type="hidden" name="_token" value="<?php echo csrf_token(); ?>">
</div>
</div>
<div class="submit">

{{ Form::submit('Login', array('class'=>'btn btn-primary'))}}
{{ Form::close() }}
<div class="forget">
<span>Forgot password?</span>
</div>
</div>
Whenever i try to login it shows tokenmismatch exception error and shows following lines of filter.php
Route::filter('csrf', function()
{
if (Session::token() != Input::get('_token'))
{
throw new Illuminate\Session\TokenMismatchException;
}
});
I have been clueless past three days...
worst is that this error automatically came , it was working fine earlier .. i did not make any changes at all !

Answer 1

It was client side issue
I just deleted cookies and then it start working.

Answer 2

You probably add the crsf filter in the /users/Signin route. You have several options:
Fistly, you can remove the crsf filter from the route.
Second, you should add the csrf token to your form input (after the <form ...> line)
{{ Form::token(); }}
Or you can change your Form declaration using the Form macro with also include the csrf token.
{{ Form::open(array('url' => 'users/Signin' ) ); }}
I hope it helps you.

Answer 3

Avoid having csrf on your GET routes since they don't have a token and will throw TokenMismatchException. With that said you could look at this snippet of code you could add in your controller to avoid these exceptions:
`class UserController extends BaseController {
/**
* Instantiate a new UserController instance.
*/
public function __construct()
{
$this->beforeFilter('auth', array('except' => 'getLogin'));
$this->beforeFilter('csrf', array('on' => 'post'));
$this->afterFilter('log', array('only' =>
array('fooAction', 'barAction')));
}
}
`
As you can see the CSRF filter is only being applied on the POST method and the auth one is only being applied on the getLogin controller method.
