Ok, what I'm trying to do is display the data from tree in a structured fashion. I'm using smarty and have tried doing some of the logic there (would prefer to if possible, at least display logic), but I'm just getting lost trying different arrays, transformations, whatever and I still cant get a basic: <ul> <li> [id] => 2 [parentId] => 1 <ul> <li> [id] => 3 [parentId] => 2 <ul> <li> [id] => 4 [parentId] => 3 <ul> <li> [id] => 9 [parentId] => 4 </li> <li> [id] => 8 [parentId] => 4 </li> </ul> </li> <li> [id] => 6 [parentId] => 3 </li> <li> [id] => 7 [parentId] => 3 </li> </ul> </li> <li> [id] => 5 [parentId] => 2 </li> </ul> </li> </ul> ...type layout...indented child under parent. Its been doing my head in now for over a week. If you've any suggestions (already trying smarty boards too with little success), they'd be much appreciated. <ul> are used here in the example, but may not be the final display method.
