Answer 1

 if($model->validate())
 {
      if(!$model->save()) // save it here!
      {
           // do stuff after successful save
      }
 }

UPDATE:

CFormModel does not have method save()

you need to extend your model from CActiveRecord

function saveInDb()
{
    $command = Yii::app()->db->createCommand(); // create a sql command and do insert here
    .
    . 
    .
}

Answer 2

Why not

if($model->validate())
{
   $model->save();
}

?

well, first of all, tf this is supposed to be a form based on table data you need to extend not from CFormModel but from CActiveRecord. second: for better readability and portability rewrite your tableName method

public function tableName()
    {
        return '{{products}}';
    }

Answer 3

Try This, Save function auto call validate form.

if($model->save()){
      echo 'add record success'.
}
else {
      echo 'failed'.
}
