What i want: check how many rows with same foodorders_id and returns to controller
What i tried:
$this->db->select('foodorders.foodorders_price,foodorders.status,COUNT(foodorders_detail.foodorders_lines');
$this->db->from('foodorders');
$this->db->join('foodorders_detail', 'foodorders_detail.foodorders_id = sales.foodorders_id', 'left');
add foodorders.foodorders_id to your select columns and add group by to your query and then get result as object or array:
hint: use alias to shorten your code.
$this->db->select('foodorders.foodorders_id,foodorders.foodorders_price,foodorders.status,COUNT(foodorders_detail.foodorders_lines)');
$this->db->from('foodorders');
$this->db->join('foodorders_detail', 'foodorders_detail.foodorders_id = foodorders.foodorders_id', 'left');
$this->db->group_by('foodorders.foodorders_id');
$query = $this->db->get();
return $query->result();
