Answer 1

Put this code into your model:
public function init() {
if ($this->isNewRecord) {
$this->student_id = $this->generate_code();
}
}
$this->generate_code() - this is your function to generate the registration number :)
Then in your view-template use something like this:
<? echo $info->student_id; ?>

Since the user registration number is a very important one and you probably need it all the time, I would recommend to store it at session when the user login. To do so, you only need the following line at your login component:
$this->setState('registration_number', $user->student_id);
Replace "$user" with the model you use to login.
Then, if you need to display this number just add:
echo Yii::app()->user->registration_number
in the place you want it to be displayed.
