[quote author="theprodigy" date="1266227253"]show me your users model, and the javascript code for your ajax company add call.[/quote]

here's my USERS MODEL:

Code:

<?
class Users_db extends Model {

    function Users_db()
    {
        parent::Model();
    }
function getCompanyDetails($data)
    {
        $this->db->where($data);
        return $this->db->get('maint_company')->row_array();        
    }

function getDetailList($ids) //Show the list of registered user with company details
    {
        $item=$this->input->post('item');
        $id = $this->input->post('ids'); //cess code added
        
        $page = $this->input->post('page');
        $limit = $this->input->post('rows'); // get how many rows we want to have into the grid
        $sidx = $this->input->post('sidx'); // get index row - i.e. user click to sort
        $sord = $this->input->post('sord'); // get the direction

        if (!$sidx) $sidx = 'sec_companyaccess.user_id'; // if we not pass at first time index use the first column for the index
        if (!$sord) $sord = 'desc';    
        

        
        if (!$page) $page = 1;
        if (!$limit) $limit = 25;
        
        $start = (($page-1) * $limit);
        
        $this->db->start_cache();
        

        $this->db->join('maint_company','sec_companyaccess.company_id=maint_company.company_id','left');
        $this->db->join('sec_users ','sec_companyaccess.user_id=sec_users.user_id','left');
        //$item = $this->input->post('sec_users.user.id');
        $this->db->from('sec_companyaccess');
        $this->db->where("sec_companyaccess.user_id", $ids);//cess code added
        $count = $this->db->count_all_results(); //code added by cess
    
        
        // calculate the total pages for the query - code added by cess
        if( $count > 0 && $limit > 0) {
              $total_pages = ceil($count/$limit);
        } else {
              $total_pages = 0;
        }
        
        // if for some reasons the requested page is greater than the total
        // set the requested page to total page - code added by cess
        if ($page > $total_pages) $page=$total_pages;
        
        // calculate the starting position of the rows
        $start = $limit * $page - $limit; // do not put $limit*($page - 1)
        
        // if for some reasons start position is negative set it to 0
        // typical case is that the user type 0 for the requested page
        if($start <0) $start = 0;        
        
        
        $this->db->select("sec_companyaccess.company_access_id as pkey,sec_companyaccess.company_access_id, maint_company.company_code, maint_company.company_name,sec_companyaccess.company_id ");
        
        $this->db->order_by($sidx,$sord);
        
        //$this->db->limit($rp, $start);
        $query = $this->db->get("sec_companyaccess");
/*        $sql = ("SELECT erp_sec_companyaccess.company_access_id as pkey,erp_sec_companyaccess.company_access_id, erp_maint_company.company_code, erp_maint_company.company_name,erp_sec_companyaccess.company_id

        $query = $this->db->query($sql);
        $num = $this->db->count_all_results();*/
        $this->db->flush_cache();
        
        $data['db'] = $query;        
        $data['page'] = $page;
        $data['totalpages'] = $total_pages;//code added by cess^^
        $data['totalrecords']=$count; //- code added by cess
        return $data;            


    }

    
    function save_companydetail($details,$id)
    {

        $this->db->insert('maint_company', $details);
        $DataId = $this->db->insert_id();
        $data['user_id'] = $id;
        $data['company_id'] = $DataId;    
        $this->db->insert('sec_companyaccess', $data);
    }
