I'm trying to get dropdown search results to paginate by the use of Datatable.But for some reason Datatable Pagination is not working properly. Is it possible to paginate search result differently? Anyone able to help please? Code is below: Index.php and loadData.php I am enclosing my search result
index.php

<?php
//index.php

$connect = new PDO("mysql:host=localhost;dbname=leadsqqe_all", "leadsqqe_bl", "gbose123BO*");

$query = "SELECT DISTINCT City FROM company ORDER BY City ASC";

$statement = $connect->prepare($query);

$statement->execute();

$result = $statement->fetchAll();

?>

    Looks like you are initializing Datatables before the data is loaded into the table. So Datatables sees an empty table. You are adding the table data directly to the DOM which Datatables doesn't know about so it always reports the table as empty.

    Try moving the Datatables init code into the success function of your Ajax call. Place it after the $('tbody').html(data); statement, like this:

            $.ajax({
                url:"loadData.php",
                method:"POST",
                data:{query:query},
                success:function(data)
                {
                    $('tbody').html(data);
                    $('#aero').DataTable({
                      "pagingType": "simple",
                      "searching": false,
                      "lengthChange": true,
                      "pageLength": 5
                  });
                }
            })

    I'm guessing by the one word response that the link didn't help you solve the problem. If you are calling load_data() more than once then you will cause a reinitialization of the Datatable with the change I suggested. In order to reinitialize the Datatable you can add the destroy option as shown in this section of the technote. Like this:

    $.ajax({
        url:"loadData.php",
        method:"POST",
        data:{query:query},
        success:function(data)
        {
            $('tbody').html(data);
            $('#aero').DataTable({
              "destroy": true,
              "pagingType": "simple",
              "searching": false,
              "lengthChange": true,
              "pageLength": 5
          });
        }
    })
