Re: [SMARTY-DEV] Variable variables

Hmmm, indeed :)))) I've tried it in an earlier release and got problems, but it works fine now. but how does smarty know what object to take? I now use {$object->$row.row} where $row.row is an attribute of $object. But what if $row is the attribute (hash?) of $object, and 'row' is an index of that hash, would it work too then? {($object->$row).row} ? Thanks for your time..
