Database Query not displaying expected output. - El Forum - 09-30-2008
[eluser]JasonS[/eluser]
I have a category structure which looks like this.
Bike
- New
Cars
Bike is the parent of New.
I am trying to create a query which will generate an array to display the above output.
What I have currently outputs
Bike
- New
But Cars gets lost. Could someone have a peek and tell me where I am going wrong.
Cheers.
Code:
$this->db->where('parent', '0');
$query = $this->db->get('categories');
$count = 0;
foreach($query->result() as $row)
{
$array[$count]['id'] = $row->id;
$array[$count]['name'] = $row->name;
$this->db->where('parent', $row->id);
$newquery = $this->db->get('categories');
if ($newquery->num_rows() > 0)
{
foreach($newquery->result() as $newrow)
{
$array[$count]['id'] = $newrow->id;
$array[$count]['name'] = ' - ' . $newrow->name;
}
}
$count++;

You miss increment the counter $count for inner for loop.
Try to use this one
Code:
foreach($query->result() as $row)
{
$array[$count]['id'] = $row->id;
$array[$count]['name'] = $row->name;
$this->db->where('parent', $row->id);
$newquery = $this->db->get('categories');
if ($newquery->num_rows() > 0)
{
foreach($newquery->result() as $newrow)
{
$count++;
$array[$count]['id'] = $newrow->id;
$array[$count]['name'] = ' - ' . $newrow->name;
}
}
$count++;
}
