        $wh =array();
        $SQL ='SELECT * FROM ci_users';
        $wh[] = "$this->session->userdata('mobile_no') = referred_by_id";
        if(count($wh)>0)
        {
            $WHERE = implode(' and ',$wh);

        }
        else
        {
            return $this->datatable->LoadJson($SQL);
        }
    }

Controller

public function datatable_json(){                                      
        $records = $this->user_working->get_all_users();
        $data = array();
        foreach ($records['data']  as $row) 
        {  
            $status = ($row['is_active'] == 0)? 'inactive': 'active'.'<span>';
            $disabled = ($row['is_admin'] == 1)? 'disabled': ''.'<span>';
                            $data[]= array(
                ucfirst($row['firstname']),
                $row['email'],
                date('F j, Y',strtotime($row['created_at'])),
                '<span class="btn bg-teal  waves-effect" title="status">'.getGroupyName($row['role']).'<span>', // get Group name by ID (getGroupyName() is a helper function)
                '<span class="btn bg-blue  waves-effect" title="status">'.$status.'<span>',         

                '<a title="Delete" class="delete btn btn-sm btn-danger pull-right '.$disabled.'" data-href="'.base_url('user/users/del/'.$row['id']).'" data-toggle="modal" data-target="#confirm-delete"> <i class="material-icons">delete</i></a>
                <a title="View" class="view btn btn-sm btn-info pull-right" href="'.base_url('user/users/edit/'.$row['id']).'"> <i class="material-icons">visibility</i></a>',

            );
        }
        $records['data']=$data;
        echo json_encode($records);                        
    }

Answer 1

The session could not be converted to the string & you are passing the session value to the column to check in the query

update your $wh[] by the following code

$wh[] = "`referred_by_id` = '{$this->session->userdata('mobile_no')}'";
