UPDATE var_export
version of the array HERE
I have the following array which I would like to group the elements/children by their UNILEVEL value:
array(
0 => array(
"member_id" => 3,
"unilevel" => 1,
"children" => array(
0 => array(
"member_id" => 4,
"unilevel" => 2,
"children" => array(
0 => array(
"member_id" => 6,
"unilevel" => 3,
"children" => array(
0 => array(
"member_id" => 7,
"unilevel" => 4 ) ) ) ) )
1 => array(
"member_id" => 9
"unilevel" => 2 ) ) )
1 => array(
"member_id" => 5,
"unilevel" => 1,
"children" => array(
0 => array(
"member_id" => 8,
"unilevel" => 2,
"children" => array(
0 => array(
"member_id" => 10,
"unilevel" => 3 ) ) ) ) ) )
The Controller below has a function named, groupPerlevel
which does the grouping, but it only groups the first parent right now, it's already a recursive function, I am not sure why it's not putting the second parent's elements on the unilevel groupings.
class TestController extends Controller {
private $group = array();
private function setGroup($value) {
$this->group = $this->group + $value;
}
private function getGroup() {
return $this->group;
}
public function create()
{
$this->groupPerlevel($tree);
dd($this->getGroup());
}
private function groupPerlevel(array $items)
{
var_dump($items);
$grouparr = $this->getGroup();
$newkey = 0;
$templevel = 1;
foreach($items as $key => $val) {
if($templevel == $val->unilevel) {
$grouparr[$templevel][$newkey] = $val;
$this->setGroup($grouparr);
} else {
if(isset($grouparr[$val->unilevel][$newkey])) {
$count = count($grouparr[$val->unilevel]);
$grouparr[$val->unilevel][$count] = $val;
$this->setGroup($grouparr);
} else {
$grouparr[$val->unilevel][$newkey] = $val;
}
}
if(isset($val->children)) {
$children = $val->children;
unset($val->children);
$this->groupPerlevel($children);
}
$newkey++;
}
$this->setGroup($grouparr);
}
}
The following array would be my desired output. array(4) { [1] is the UNILEVEL (group) so all elements/children should be in their proper unilevel group based on their unilevel field value. But it only does that for the first parent, the second parent doesn't group.
array(
1 => array(
0 => array(
"member_id" => 3,
"unilevel" => 1 ) )
4 => array(
0 => array(
"member_id" => 7,
"unilevel" => 4 ) )
3 => array(
0 => array (
"member_id" => 6,
"unilevel" => 3 ) )
2 => array(
0 => array(
"member_id" => 4,
"unilevel" => 2
1 => array(
"member_id" => 9
"unilevel" => 2 )))
