Hi,
I declare by "custom" row vars as follows (note the underscore):
protected $_tags = null; // array of tags from tags table linked to this row
protected $_user = null; // user row object (note: only id saved to cached
version)
then I have setter and getter for this custom variable.
My cached row objects have these custom variables saved with help of __sleep
function I have overriden:
/**
* Store row class and selected properties in serialized object
* __sleep() function is called when object is serialized
*
* @return array
*/
public function __sleep()
{
// get custom variables from row object (in array format)
$this->_setSleepProperties();
// merge custom variables with Zend_Db_Row_Abstract __sleep()
result
return array_merge(parent::__sleep(), $this->_sleepProperties);
}
br, Marko
