Answer 1

$this->db->select('*');

$this->db->from('table1');

$this->db->join('table2','table1.id=table2.id'); 

$this->db->join('table3','table2.id=table3.id');

$this->db->join('table4','table3.id=table4.id'); 

$this->db->join('table5','table5.id=table4.id');

$this->db->where('table5.id',$this->session->userdata('id'));//getting value from session and match the id of table5 and then show data

$data=$this->db->get()->result();//all data store in $data variable
