    Question How to fetch data on same page without reloading it?

    I have following code

    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">
    <?php
    include 'connect.php';
    ?>

    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <title>index</title>
    </head>
    <?php
    function select_society()
    {
    if(isset($_POST['society']))
    {
    $society=$_POST['society'];
    if($society=="select_society")
    {

    }
    else
    {
    $sql=mysql_query("select society_code from society where society_name='$society'");
    $result=mysql_fetch_array($sql);
    $society_code=$result['society_code'];

    echo "Selected society and its code are<br><Br>";
    echo "society_code: ".$society_code."<br><br>";
    echo "society_name: ".$society."<br><br>";
    select_customer($society_code);
    }
    }
    }

    function select_customer($society_code)
    {
    $society_code2=$society_code;
    $sql=mysql_query("select customer_id,customer_name from bill_cycle where society_code='$society_code2'");
    $result=mysql_fetch_array($sql);
    $customer_id=$result['customer_id'];
    $customer_name=$result['customer_name'];

    echo "The customer code is: '$customer_id' and customer name is: '$customer_name'<br><br>";

    }

    function select_next()
    {
    echo "here";
    }

    ?>
    <body>

    <div id="wrapper">
    <form name="index_form" method="post" action="index.php">
    <div id="select_society">
    <select name="society">
    <option value="select_society">Select society</option>
    <option value="shantinagar">Shantinagar</option>
    <option value="Mahalakshminagar">Mahalakshminagar</option>
    </select>
    </div>
    <div class="submit_button">
    <input type="submit" name="submit" value="select society"/>
    </div>

    <?php
    select_society();
    ?>

    </form>
    </div>
    </body>
    </html>
    It gives me output as well

    Selected society and its code are

    society_code: s_11

    society_name: shantinagar

    The customer code is: '1' and customer name is: 'suyash'
    Now my requirement is, I want to add a next button in this page, and when I click that button(or link), the next record from the database should be displayed on the same page.
    I tried it by using next button and link but its not working. What are the options to do so?

    Ajax will definitely do this job ! Google "Ajax" and will find much more info about it! I assume you are already familiar with javascript!
