How can I create a custom function for validation rules in yii?

Question

I have created a form with some entities (say name,address,etc.). And I have defined validation rules in model class. Client side validation is working perfectly as desired. Now I need to create custom validation rules. For that,in reference with http://www.yiiframework.com/wiki/168/create-your-own-validation-rule/#hh0 , I have created a method called valid_number() in my model, and defined a simple null checking (I know there are built in rules for validating null,email,password, etc.. Here I have demonstrated a simple method of validation, actually I'm planning to do some custom validations). Please refer the code below. And please let me know what I am doing wrong.

//model

class Employee extends CActiveRecord{
  public $number;
  public function rules(){
     return array(
                  array('number','valid_number'),
                  );
  }


 public function valid_number($attribute,$params){
    if($this->$attribute == '' ){
         CModel::addError($attribute, 'Number is null');
    }
   }

//view

</fieldset>
   <?php echo $form->textFieldRow($model, 'number'); ?>
</fieldset>

So what exactly happens? Is your method called? What does var_dump($this->$attribute) output? — Jon

CModel::addError should be $this->addError.

'Didn't work' doesn't work, whats the output? whats the error? what info do you have from a debug attempt?

@Pradeep You should call CFormModel::error function to display number attribute errors. like this: <?php echo $form->error($model, 'number'); ?> and if just validate attribute is empty, you maybe can try required validator

<?php 
$this->addError($attribute, 'Your error message');
?>

Why are you calling the static function CModel::addError?

You could just call addError of the object and it works:

public function valid_number($attribute, $params) {
    if ($this->$attribute == '' ) {
        $this->addError($attribute, 'Number is null');
    }
}
