	    $rules = array(
		  	'name' => 'required',
		  	'email' => 'required|email',
			'subject' => 'required',
			'g-recaptcha-response' => 'required|captcha',
			'msg' => 'required',
		$validator = Validator::make($data, $rules);
		if ($validator->fails()){
		    return Redirect::to('/contact')->withInput()->withErrors($validator);
		    // Do your stuff.

Routes : Now add your contact routes in “Http/routes.php”.

Route::get('contact', function() {
  return View::make('contact');
Route::post('contact', 'EnquiryController@index');
