If you have a form element (perhaps a hidden one), you can write the JavaScript variable to it and submit the form: <form name="frm" action="<?= $_SERVER["SCRIPT_NAME"]; ?>" method="get"> <input type="hidden" name="foo" /> </form> ... <script type="text/javascript> document.frm.foo.value = "bar"; document.frm.submit(); </script> Or, you could just use JavaScript to tack on a query string: <script type="text/javascript" location.href += "?foo=bar"; </script> Either way, once the JavaScript is executed, the page will be reloaded with a query string tacked on. This is read using the $_GET superglobal: <? if (isset($_GET) && array_key_exists("foo", $_GET)) { $FOO = $_GET["foo"]; // Now you can use the variable $FOO, which contains // the value which was passed through the query string // from the JavaScript. } ?> It's important to keep in mind though that JavaScript and PHP are handled completely separately - you can't have scripts of both kinds interact within the same document, because they are executed separately.

Is there a way to get the value of a javascript variable and put it into a php variable? Thanks Paul. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
