how we can add rule in Yii model for input must be greater than 0

Question

do anyone know how can I apply rule in Yii model for input must be greater than 0 value, without any custom approach ..

like :

public function rules()
{
    return array( 
        ....
        ....

            array('SalePrice', 'required', "on"=>"sale"),

        ....
        ....
    );
}

many thanks ..

Solution 1

Simpler way array('SalePrice', 'numerical', 'min'=>1)

with a custom validator method

array('SalePrice', 'greaterThanZero')

 public function greaterThanZero($attribute,$params)
   {

      if ($this->$attribute<=0)
         $this->addError($attribute, 'Saleprice has to be greater than 0');

 }

Solution 2

I see it is a price so you could use 0.01 (a penny) as a minimum value like so:

array('SalesPrice', 'numerical', 'min'=>0.01),

Note that this solution does not validate that the number entered is a price, just that it is > 0.01
