Implementing a custom getter in Yii?

I am working with Yii and I have the following situation:

I have a MySQL table:

charges {
    id INT AUTOINCREMENT,
    name VARCHAR(256),
    value DOUBLE
}

Then I have the model from this table. And finally I have the views for create, list, admin, update and view.

In the admin and view views I want to display the value field formated with two decimal numbers. One option to do this could be in the view and admin files format the number. Is there a way to create a method in the model and then not having to do anything in the views but the method itself will solve formating the number?

thanks

You can override the afterFind() method of CActiveRecord in your model and format the value field in it.

Alternatively you could also declare a virtual attribute of the model, and set it in the afterFind() method, and use this virtual attribute in the views.

Example(with virtual attribute):

Class ChargesModel extends CActiveRecord{
    public $valueModified;

    /*
     * other code
     */

    protected function afterFind(){
        parent::afterFind();
        // in the following line i'm just making $valueModified and $value equal, but obviously you would have to insert the 2 decimals
        $this->valueModified=$this->value;
    }
}

Then you can access the virtual attribute like this : $modelObject->valueModified

I would recommend you to use the virtual attribute, because you then have both the unmodified $value and modified $modifiedValue, once the formatting is done, we can use either as required, and not have to reformat back to original when we need the original.
