Try to combine two Codeigniter scripts, to export data from mysql to excel

Question

I found two awesome scripts on Tech Arise Team website. The first one is: http://techarise.com/export-data-to-excel-using-codeigniter/ and the second one is: http://techarise.com/datatable-server-side-processing-codeigniter-mysql-ajax-custom-search/. I try to combine these scripts, that i get a form, which can be export filtered data to excel, based on user's input date range, in Codeigniter framework. The scripts, which i modified, is these: application/controllers/Order.php:

class Order extends CI_Controller {

    public function __construct() {
        parent::__construct();
        $this->load->model('Site_model', 'site');
    }
    // upload xlsx|xls file
    public function index() {
        $data['page'] = 'order';
        $data['title'] = 'Data Table | TechArise';
        $this->load->view('order/index', $data);
    }
    // get Orders List
    public function getOrderList() {    
        $orderID = $this->input->post('order_id');
        $name = $this->input->post('name');
        $startDate = $this->input->post('start_date');
        $endDate = $this->input->post('end_date');        
        if(!empty($orderID)){
            $this->site->setOrderID($orderID);
        }        
        if(!empty($name)){
            $this->site->setName($name);
        }                
        if(!empty($startDate) && !empty($endDate)) {
            $this->site->setStartDate(date('Y-m-d', strtotime($startDate)));
            $this->site->setEndDate(date('Y-m-d', strtotime($endDate)));
        }        
        $getOrderInfo = $this->site->getOrders();
        $dataArray = array();
        foreach ($getOrderInfo as $element) {

Other scripts aren't modified.

The problem is that the exported file contains all data from the data table, not just the filtered. :/ Test site is: https://tvep.hu/data-search/ What do I do wrong?

Answer 1

write your base_url instead of HTTP_UPLOAD_IMPORT_PATH and also ROOT_UPLOAD_IMPORT_PATH
