Laravel post : routing issue - php

Question

So, i started with laravel. Tried with making a form post to the same page.
Here's what i have so far,
routes.php
Route::get('/', 'HomeController#showWelcome');
Route::group(array('before' => 'csrf'), function () {
Route::post('contactus', 'HomeController#sendEmail');
});
hello.php
<?php echo Form::open(array('action' => 'HomeController#sendEmail'))?>
input fields here
<?php echo Form::close() ?>
HomeController
public function showWelcome()
{
return View::make('hello');
}
public function sendEmail()
{
print_r($_POST);exit;
}
Problem: Form gets posted to the url public/contactus
Can someone point out which really stupid thing, i am doing?

Answer 1

routes.php
Route::get('/', 'HomeController#showWelcome');
Route::post('/', array(
'before' => 'csrf', // csrf filter
'uses' => 'HomeController#sendEmail' // the controller action to be used
));
hello.php
<?php echo Form::open(array('action' => 'HomeController#sendEmail')) ?>
<!-- input fields here -->
<?php echo Form::close() ?>
HomeController.php
Public function showWelcome()
{
return View::make('hello');
}
public function sendEmail()
{
$data = Input::all();
print_r($data);
// return the same view but with posted fields in the $data array
return View::make('hello', $data);
}

Answer 2

Routes
Route::get('/', 'HomeController#showWelcome');
Route::post('/', 'HomeController#sendEmail');
Hello.blade.php
#if(isset($post))
{{$post}}
#endif
{{Form::open()}}
{{Form::text('sometext')}}
{{Form::close()}}
HomeController
Public function showWelcome()
{
return View::make('hello');
}
public function sendEmail()
{
$post = Input::all();
return View::make('hello', array('post' => $post));
}
