Hi all,
I just wanted to re-visit this again. I've come back after a couple of
weeks break to attempt to finish this project, in particular the
'parent' select list which needs to be indented (for ease of use). Now
I found what I thought was the perfect bit of code by 'Othy' here:
http://othy.wordpress.com/2006/06/03/generatenestedlist/
It's supposed to generate nested lists for use with select/drop downs.
It's a bit light on the documentation and I'm having trouble getting
it to work.
As per the instructions, in my app_controller.php file I put the
following code:
function generateNestedList($indent = ' ',$sort = null)
{
$this->recursive = '-1';
$cats = $this->findAllThreaded(null,
array($this->name.'.id',$this-
>name.'.name',$this->name.'.parent_id'), $sort);
$glist = $this->_generateNestedList($cats,$indent); return
$glist;
}
function _generateNestedList($cats,$indent,$level = 0)
{
static $list = array();
for($i = 0, $c = count($cats); $i < $c; $i++)
{
$list[$cats[$i][$this->name]['id']] =
str_repeat($indent,$level).
$cats[$i][$this->name]['name']; if(isset($cats[$i]['children']) && !
empty($cats[$i]['children']))
{
$this->_generateNestedList($cats[$i]['children'],$indent,$level
+
1);
}
}
return $list;
}
Now in my controller (called Nodes) I've got:
$this->set('category_tree', $this->Node->generateNestedList('--',
null));
This seems correct and doesn't produce any errors, however when I try
to use the category_tree in a selectTag in my view, I get nothing:
<?php echo $html->selectTag('Node/parent_id', $category_tree, $html-
>tagValue('Node/parent_id'), array(), array(), true);?>
If I just print_r $category tree, it's also empty.
Has anybody got experience with this snippet of code by Othy (I'd ask
him directly but there doesn't seem to be any contact info on his
page)? Or could somebody please give me some pointers??? Alternatively
another method would be appreciated.
Thanks again,
Brett.
