You will need to do something like this,

$insertIds  = array();
for ($x = 0; $x < sizeof($filtername); $x++) {
    $orders = array(
        'poid'              => null,
        'order_id'          => $poid,
        'item_desc'         => $filtername[$x],
        'item_qty'          => $filterquantity[$x],
        'item_price'        => $filterprice[$x],
        'total'             => $filtertotal[$x],
        'cash_on_delivery'  => $val_delivery,
        'is_check'          => $val_check,
        'bank_transfer'     => $val_transfer,
        'transaction_date'  => $dateorder
    );
    $this->db->insert('po_order', $orders);
    $insertIds[$x]  = $this->db->insert_id(); //will return the first insert array
}
print_r($insertIds); //print all insert ids
