Answer 1

Use this function in controller
public function getTableData()
{
$this->db->select('GROUP_CONCAT(id) as id');
$tbl0 = $this->db->get('table0')->row_array();
if($tbl0) {
$ids = explode(',', $tbl0['id']);
$this->db->where_in('id', $ids);
$tbl1 = $this->db->get('table1')->result_array();
echo "<pre>"; print_r($tbl1);
}
}

Hope this will help you;
Get all ids in an array name here ids and use where_in outside the loop
public function get_quick_navi_menu($q_code)
{
$this->db->select("*");
$this->db->where('q_id',$q_code);
$this->db->from("table0");
$q = $this->db->get();
$final = array();
if ($q->num_rows() > 0)
{
foreach ($q->result() as $key => $row)
{
$ids[$key] = $row->id;
$data[$key] = $row;
}
$this->db->select("*");
$this->db->from("table1");
$this->db->where_in("id",$ids);
$q = $this->db->get();
//echo $this->db->last_query();
if ($q->num_rows() > 0)
{
if ( ! empty($data))
{
foreach ($data as $key => $item)
{
$item->children = $q->result();
$final[] = $item;
}
}
}
}
return $final;
/*print_r($final);*/
}
In your controller class:
make sure you have loaded your model and database in controller or in autoload.php
$q_code = 'q_code_value';
$data['menus'] =$this->Home_model->get_quick_navi_menu($q_code);
/* pass the $data in the view like this*/
$this->load->view('your_view_file_path',$data);
In your view :
<div><?php print_r($records);?></div>
