This can be done by using the <a href="http://datatables.net/ref#fnServerParams">fnServerParams</a> callback function which is called whenever an XHR is sent to the server. fnServerParams Takes a single parameter, the array of name/value pairs of parameters that are to be sent to the server. You can manipulate this as you require - typically adding another parameter, as shown in this example.</p> <h1>Live example</h1> <div id="dynamic"> <table cellpadding="0" cellspacing="0" border="0" class="display" id="example"> <thead> <tr> <th width="20%">Rendering engine</th> <th width="25%">Browser</th> <th width="25%">Platform(s)</th> <th width="15%">Engine version</th> <th width="15%">CSS grade</th> </tr> </thead> <tbody> <tr> <td colspan="5" class="dataTables_empty">Loading data from server</td> </tr> </tbody> <tfoot> <tr> <th>Rendering engine</th> <th>Browser</th> <th>Platform(s)</th> <th>Engine version</th> <th>CSS grade</th> </tr> </tfoot> </table> </div> <div class="spacer"></div> <h1>Initialisation code</h1> <pre class="brush: js;">$(document).ready(function() { $('#example').dataTable( { "bProcessing": true, "bServerSide": true, "sAjaxSource": "scripts/server_processing.php" "fnServerParams": function ( aoData ) { aoData.push( { "name": "more_data", "value": "my_value" } ); } } ); } );</pre> <style type="text/css"> @import "../examples_support/syntax/css/shCore.css"; </style> <script type="text/javascript" language="javascript" src="../examples_support/syntax/js/shCore.js"></script> <h1>Server response</h1> <p>The code below shows the latest JSON data that has been returned from the server in response to the Ajax request made by DataTables.
