插入数据库但不工作;没有错误发生

Question

我有问题。 我正在尝试将值插入数据库，但问题是，它不会进入数据库，也不会显示错误消息。 我的roues.php is

 Route::group(array('prefix' =>'/addteacherlist'),function()
    {
    Route::get('/', array('uses'=>'AddteacherlistController@addteacherlist','as'=>'addteacherlist'));
    Route::post('/', array('uses'=>'AddteacherlistController@getteacherlist','as'=>'getteacherlist'));
     });

我的controller.php

 $user=new ForumTeacher();
 $user->tname=Input::get('tname');
 $user->tmobile=Input::get('tmobile');
 $user->ttype=Input::get('ttype');
 $user->tcls=Input::get('tcls');
 $user->tdivn=Input::get('tdivn');
 $user->tsubject=Input::get('tsubject'); 

 if($user->save()) {
 return Redirect::route('teacherlist') ->with('success','you entered sucessfully.');
 }
