I'm doing a simple forum which should support nested replies. So, I
decided to use the Tree Behavior.
models/forum_entry.php
-----------------------------------------------------------------
<?php
class ForumEntry extends ForumAppModel {
var $name = 'ForumEntry';
var $displayField = 'subject';
var $actsAs = array('Tree', 'Containable');
var $belongsTo = array('User');
}
?>
-----------------------------------------------------------------
The tree in my database looks like this:
- Testing
--- ASubSubject
------ ASubSubSubject
- Another Subject
How do I retrieve a node with parent_id = 0 (like "Testing" or
"Another Subject") and all of its children while preserving the tree
structure?
Using $this->ForumEntry->children($id) flattens the tree structure to
this:
-----------------------------------------------------------------
Array
(
[0] => Array
(
[ForumEntry] => Array
(
[id] => 5
[parent_id] => 4
[lft] => 2
[rght] => 5
[user_id] => 1
[subject] => ASubSubject
[body] =>
[created] => 2008-07-01 22:58:56
[modified] => 2008-07-01 22:58:56
)
)
[1] => Array
(
[ForumEntry] => Array
(
[id] => 6
[parent_id] => 5
[lft] => 3
[rght] => 4
[user_id] => 1
[subject] => ASubSubSubject
[body] =>
[created] => 2008-07-01 23:16:52
[modified] => 2008-07-01 23:16:52
)
)
)
-----------------------------------------------------------------
Suggestions are very much appreciated :) Been wasting a whole day on
this issue now.
Thanks in advance!
