PHP Code:
function minus_set($id)
{
$this->db->trans_start();
$this->db->set('total_set', 'total_set - 1');
$this->db->set('price', 'price - 300.00');
$this->db->where('user_id', $user_id);
$this->db->update('users_detail', $data);
$this->db->trans_complete();
if ($this->db->trans_status() === TRUE)
{
return true;
}
else
{
return false;
}
}
thanks
