Answer 1

EDIT: Using own function in validation rules- In the rule specify the function with attribute like this-

array('username','checkuniquename'),

Then define the function logic in same model Like this:

public function checkuniqueemail($attribute)
{
    $record=Users::model()->findByAttributes(array($attribute=>$this->email));
    if($record!==null)
         $this->addError($attribute, 'This email has been already taken please choose a different one');

}

You can define multiple validation rules on single attribute in Yii models.

return array(
                    array('contact_no','numerical', 'integerOnly'=>true),
                    array('contact_no','length', 'min'=>8 ),
                    array('name, contact_no', 'required'),
        array('name, contact_no', 'length', 'max'=>255),
        array('password','pattern'=>'/^[A-Za-z0-9_!@#$%^&*()+=?.,]+$/u', 'message'=>'Spaces or given characters are not allowed'),
    );

There is lot of validation you can specify in your model.

Answer 2

First you need to specify a validation rule in your model like

return array(
.......    
array('duration', 'days_available'),
.....

);

where duration is the field name and days_available will be the function name. Then you need to write the function within the model.

public function days_available($attribute,$params)
{
  //provide proper condition
  $this->addError('duration','validation message');
}
