Thanks David, Here's my tree creation. I'm trying to either put depth count
on each array or run through the tree and figure it out after. I just can't
figure out where to put it :D
Great very lightweight script to create a tree from parent id and id if you
want to save this one for yourself btw.
function createTree(&$list, $parent){
$tree = array();
//$depth = 0;
foreach ($parent as $k=>$l){
//echo $k.'<br />';
if(isset($list[$l['section_id']])){
//echo $k.'<br />';
$l['depth'] = $k;
$l['children'] = createTree($list, $list[$l['section_id']]);
} else {
$l['depth'] = 0;
}
$tree[] = $l;
}
return $tree;
}
$arr = $dashSections;
$new = array();
foreach ($arr as $a){
$new[$a['section_parent_id']][] = $a;
}
// CREATE THE TREE
$tree = createTree($new, $new[0]);
//echo count($tree);
//print_r($tree);
