Hi Everyone,

I am completely new to this data table stuff. I am trying to show data from MySQL database using Jquery Data table however I am facing an issue here. So my data loads upon loading the page however whenever I try to next page button it doesn't go to next page and do not load data on screen but it shows required data when I checked my Ajax Response. Moreover, Searching and sorting functions are also not working. I have included all necessary CDNs so I believe source file are not an issue.

your expert guidance will be highly appreciated on this matter on urgent basis....I have mentioned my code as follows...

include_once 'db_config.php';

ini_set('display_errors', '1');
ini_set('display_startup_errors', '1');

                <th>Last Name</th>
                <th>Email </th>
$(document).ready(function() {
    $('#example').DataTable( {
        //"processing": true,
        "serverSide": true,
        "ajax": {
        "columns": [
            {"data": "user_id"},
            {"data": "user_name"},
            {"data": "fname"},
            {"data": "lname"},
            {"data": "eml"},
            {"data": "gnd"}

include_once 'db_config.php';

ini_set('display_errors', '1');
ini_set('display_startup_errors', '1');

$start = $_POST['start'];
$end = $_POST['length'];

$sql = $conn->query("SELECT * FROM user_list LIMIT $start, $end");  

$sql1 = $conn->query("SELECT * FROM user_list");  
//$page_result = $sql;  
$total_records = $sql1->rowCount(); 
$data = array();
while($row = $sql->fetch()){ 
    $data[] = array(
$output  = array(
    'draw' => 1,
    'recordsTotal' => $total_records,
    'recordsFiltered' => $total_records,
    'data' => $data,
echo json_encode($output);

    You've enabled serverSide so the server script should only return the data for the required page. It looks like you've hard-wired draw to 1 - this needs to match the draw in the request. The protocol is discussed here. Also see examples here.

    To make things simpler, if you're not expecting many records, say less that 10k, you can remove that option as the client is able to efficiently deal with that much data.
