MethodNotAllowedHttpException in RouteCollection.php in Lara

routes.php

Route::get('/',array('uses'=>'student@index'));
Route::get('/view',array('uses'=>'student@view'));
Route::post('/save',array('uses'=>'student@save'));

这是代码，我正在处理表单，当我提交表单时，它显示了这个错误：

RouteCollection.php中的MethodNotAllowedHttpException第201行：

student.php

class student extends Controller  {
    public function index()
     {   
         //return 'hello world';
        return 'View::make('student.index');
      }
          public function view()
     {
        return 'View::make('student.view');
      }
          public function save()
     {
        //return 'View::make('student.view');
        $validation= array(
                      'first_name'=>'required',
                      'email'=>'required'
                          );
        $v1=validator::make(Input::all(),$validation);
        if( $v1->fails())
        {
        return Redirect::to('view')->withErrors($v1);
        }
        else
        { $poststudent=Input::all();
          $data = array('first_name'=>$poststudent['first_name'],
                         'last_name'=>$poststudent['last_name'],
                         'email'=>$poststudent['email'],
                         'interested'=>$poststudent['interested'], 
                         'skills'=>$poststudent['skills']);
        $check=0;
        $check=DB::table('students')->insert($data);
        if($check > 0)
        {
        return Redirect::to('/');
        }
        else
        {
        return Redirect::to('/view');
        }
        }

      }
        }

形式如下：

<form action="<?=URL::to('/save')?>" methed="POST">
<div class="form-group">
 <label for= "first_name"> FIRST NAME </label>
<input name="FIRST NAME" type="text" value="" class="form-control" id="first       name"/>
</div>

我被困在这里了。
