Answer 1

try this..
$this->db->select('ca.*,ci.Name,a.date,a.status');
$this->db->from('cases'.' ca');
$this->db->join('clients'.' ci','ca.client_id=ci.id','left');
$this->db->join('attendance'.' a','a.client_id=ci.id','left');
return $this->db->get();
go through the user guide if u want to read more about join and active records...

Answer 2

Here's a very simple example to get you started with any number of join common fun for all
Construcor Code
Construct $joins as array:
$joins = array(
array(
'table' => 'table2',
'condition' => 'table2.id = table1.id',
'jointype' => 'LEFT'
),
);
Example function handling joins as an array:
public function get_joins($table, $columns, $joins)
{
$this->db->select($columns)->from($table);
if (is_array($joins) && count($joins) > 0)
{
foreach($joins as $k => $v)
{
$this->db->join($v['table'], $v['condition'], $v['jointype']);
}
}
return $this->db->get()->result_array();
}
