justpee

anyone can help? i wanted to do something like e.g. when the user click on radio button, id =RadioGroup2_0 it will set the session variable $_SESSION['SELFPOST'] to shopping.php. but the problem is, it didnt works as what i have thought.. <input name="RadioGroup2" type="radio" id="RadioGroup2_0" value="5" checked="checked" /> <input type="radio" name="RadioGroup2" value="10" id="RadioGroup2_1" /> <script type="text/javascript"> { document.getElementById('RadioGroup2_1').innerHTML = '<?php session_start(); $_SESSION['SELFPOST'] = "shipping.php"; ?>'; }
