Still wrestling with this issue. Managed to contact the author of the script and they re-wrote it a bit, but still no joy for me. See comments here: http://othy.wordpress.com/2006/06/03/generatenestedlist/
The generateNestedList() function just produces an empty variable. I did notice in debug mode that I'm getting an SQL error. Some how the function is trying to query the database with the string 'generateNestedList'. Just to re-cap what I've got in my app: --In the app controller file I've got the snippet from othy which includes the generateNestedList() function - http://othy.wordpress.com/2006/06/03/generatenestedlist/ --In my Model I've just got: class Node extends AppModel { var $name = 'Node'; //The Associations below have been created with all possible keys, those that are not needed can be removed var $belongsTo = array( 'NodeType' => array('className' => 'NodeType', 'foreignKey' => 'node_type_id', 'counterCache' => '' ), ); } --In my Controller (for the edit function) I've got: function edit($id = null) { if(empty($this->data)) { if(!$id) { $this->Session->setFlash('Invalid id for Node'); $this->redirect('/nodes/index'); } $this->data = $this->Node->read(null, $id); $this->set('nodeTypes', $this->Node->NodeType->generateList()); $this->set('category_tree', $this->Node->generateNestedList()); // <--this is the line in question } else { $this->cleanUpFields(); if($this->Node->save($this->data)) { $this->Session->setFlash('The Node has been saved'); $this->redirect('/nodes/index'); } else { $this->Session->setFlash('Please correct errors below.'); $this->set('nodeTypes', $this->Node->NodeType->generateList()); } } } --And in my view I've got: <?php echo $form->labelTag('Node/parent_id', 'Parent Id');?> <?php echo $html->selectTag('Node/parent_id', $category_tree, $html- >tagValue('Node/parent_id'), array(), array(), true) --My Nodes DB schema looks like this: http://housepimp.com/cake_nodes.gif Any help would be much appreciated.
