To pass information from php to javascript is fairly easy. In the form section you can do something like this: <form name="InfoPassed" action="MaterialModule.php" method="post"> <input type="text" name="PhpVariable" value="<?php print $_SESSION['Name']; ?>"/> </form> <script type="text/javascript"> var value=document.InfoPassed.PhpVariable.value; </script> but doing it the other way (i.e. from Javascript to PHP) is impossible without involving the submit button <form name="InfoPassed" action="MaterialModule.php" method="post"> <input type="text" name="PhpVariable"/> <input type="submit" value="Submit"/> </form> <script type="text/javascript"> document.InfoPassed.PhpVariable.value=200; </script> <?php if(isset($_POST["PhpVariable"])){ //do stuff with variable } ?> I'm more than happy to be corrected but none of the examples stated it was possible to do it without the submit button. ---- Server IP: 69.147.83.197 Probable Submitter: 86.147.83.149 ---- Manual Page -- http://www.php.net/manual/en/faq.html.php Edit -- https://master.php.net/note/edit/105356 Del: integrated -- https://master.php.net/note/delete/105356/integrated Del: useless -- https://master.php.net/note/delete/105356/useless Del: bad code -- https://master.php.net/note/delete/105356/bad+code Del: spam -- https://master.php.net/note/delete/105356/spam Del: non-english -- https://master.php.net/note/delete/105356/non-english Del: in docs -- https://master.php.net/note/delete/105356/in+docs Del: other reasons-- https://master.php.net/note/delete/105356 Reject -- https://master.php.net/note/reject/105356 Search -- https://master.php.net/manage/user-notes.php
