[Code Igniter] giúp mình vấn đề multi form trong 1 view

function search_tour()
    {
        $data['page_title'] = "Tìm kiếm";
        $data['ne'] = $this->view_model->get_all_news_events1();

        if($this->_validate_search() == FALSE) {
            $this->load->view('view/search_result', $data);
        } else {
            $location = $this->input->post('search');
            $data['datas'] = $this->view_model->search_tour($location);
            if($data['datas']->num_rows() == 0) {
                $data['msg'] = 0;
            } else {
                $data['msg'] = $data['datas']->num_rows();
            }
            $this->load->view('view/search_result', $data);
        }         
    }

function do_booking($tour_code)
    {
        $data['ne'] = $this->view_model->get_all_news_events1();
        $data['page_title'] = "Đặt Tour";
        $data['country'] = $this->booking_model->get_all_country();
        $data['tour_info'] = $this->booking_model->get_tour_by_code($tour_code);

        if($this->_validate_booking() == FALSE) {
            $this->load->view('view/do_booking', $data);
        }
    }

//_validate_search() và _validate_booking() là 2 method dùng validate form

<?php
$this->load->view('header');
$this->load->view('left');
?>
<?php echo form_open("view/do_booking/{$tour_info->row()->tour_code}");?>
<table cellspacing="2" cellpadding="2" width="100%">
//bỏ 1 số code
<tr>
        <td colspan="2" align="center">
            <input type="submit" name="book_tour" id="book_tour" value="Đặt Tour" />
            <?=  form_reset('reset','Nhập lại');?>
        </td>
    </tr>
</table>
<?php form_close();?>

<?php
$this->load->view('right');
$this->load->view('footer');
?>

<?php echo form_open( "view/search_tour");?>
        <table cellspacing="3" cellpadding="3" width="100%">
           //bỏ 1 số code
            <tr>
                <td colspan="2"><input type="submit" name="s_tour" id="s_tour" value="Tìm kiếm" /></td>
            </tr>
            <tr>
                <td colspan="2"><?php echo form_error('search');?></td>
            </tr>
        </table>
    <?php form_close();?>

<?php echo form_open( "view/search_tour");?>

<?php echo form_open("view/do_booking/{$tour_info->row()->tour_code}");?>
