Data Not Populating In Cgridview Using Cformmodel

Hi I’m new to yii i’m having a problem with my simple application having a create and view function. My data did not populate in my CGridView. My code looks like this:

here’s my Student.php (model)




class Student extends CFormModel{

   

    

    public $id;

    public $fname;

    public $lname;

    public $midinitial;

    public $yrlevel;

    public $isNewRecord;

    

        public function tableName()

         {

                    return 'student';

         }

    

         public function attributeLabels()

        {

                    return array(

                            'id' => 'Student ID',   

                            'fname' => 'First Name',

                            'lname' => 'Last Name',

                            'midinitial' => 'Middle Initial',

                            'yrlevel' => 'Year level',

                            

                    );


         }

    

    

        public function viewStudent(){

          

        $conn = Yii::app()->db;

 

        $sql = "Select * from student";

        

        $command = $conn->createCommand($sql);

 

        $result = $command->queryAll();

        

        return $result;


       }  

      

      public function createStudent(){

         

         $conn = Yii::app()->db;


         $sql = "INSERT INTO student(fname,lname,midinitial,yrlevel)VALUES(:fname,:lname,:midinitial,:yrlevel)";


         $command = $conn->createCommand($sql);

         

         $command->bindParam(":fname",$fname,PDO::PARAM_STR);

        

         $command->bindParam(":lname",$lname,PDO::PARAM_STR);


         $command->bindParam(":midinitial",$midinitial,PDO::PARAM_STR);


         $command->bindParam(":yrlevel",$yrlevel,PDO::PARAM_STR);

   

         $command->execute();


        

     }



and here’s my StudentController.php (controller)


class StudentController extends Controller {

   

    

      public $layout='//layouts/column1';

    

    

     public function actionIndex()

	{

		

	$model = new Student();

         

        $result = $model->viewStudent(); 

               

        $dataProvider = new CArrayDataProvider($result);

        

        $this->render('index',array('dataProvider'=>$dataProvider));

             

                                

        }

    

     

    public function actionView(){

        

        $model = new Student();

       

        $result = $model->viewStudent();    

        

        $dataProvider = new CArrayDataProvider($result);

        

        $this->render('index',array('dataProvider'=>$dataProvider));

        


   }

        

        

     /* public function actionView($id)

	{

		$this->render('view',array(

			'model'=>$this->loadModel($id),

		));

        }*/

    

    

      public function actionCreate(){

        

        $model = new Student();

        

        if(isset($_POST['Student']))

		{

			$model->attributes=$_POST['Student'];

                        

			//if($model->createStudent())

				$this->redirect(array('index','id'=>$model->id));

		}


        $this->render('create',array(

         'model'=>$model,

         'create'=>$model,// Model is passed to create.php View!

    ));

  

    }



and here’s my index




<?php

$this->breadcrumbs=array(

	'student',

);


$this->menu=array(

	array('label'=>'View Student', 'url'=>array('view')),

	array('label'=>'Create Student', 'url'=>array('create')),

);

?>


<h1>Student</h1>




<?php $this->widget('zii.widgets.grid.CGridView', array(

	'id'=>'student-grid',

	'dataProvider'=>$dataProvider,

                'columns'=>array(

		'id',

		'fname',

		'lname',

		'midinitial',

                'yrlevel',  

                    

               

	

	),
