Hello, everybody!
Help me please.
Depending on category, I need to output all the products from the subs and from the current category.
More detail:
My table of catalog [catalog_id,title,parent_id] and products[id, catalog_id].
Graphic scheme of my cat-data:
1(0)-2(1)-3(2)
-4(2)
4(0)-5(4)
6(0)
When user open for example catalog_id=1 must be output all products from 1,2,3,4 categories or when catalog_id = 2 only 2, 3 and 4 cats.
For this reason I used recursive function:
Code:
public function get_ids($cid)
{
$qry = $this->db->select('catalog_id')
->from('catalog')
->where('parent_id',$cid)
->get();
$arrResult = array();
if($qry->num_rows > 0) {
$t = $qry->result_array();
foreach($t as $row){
$arrResult[$row['catalog_id']] = $this->get_ids($row['catalog_id']);
}
}
return $arrResult;
}
So I got next array (when catalog_id = 1):
Array ( [2] => Array ([3] => Array() [4] => Array() )
Than I need use recursion again to get all the products. And it`s too difficult and too much weight.
How can I simplify this task?
Maybe there is possibility to get array without tree`s structure:
Array ( [2] => array(catalog_id =>2) [3] => array(catalog_id =>3) [4] => array(catalog_id =>4) ) ?
