$_SESSION['anything'] failure

DickDeeds

I have a javascript program that works OK in firefox, safari and chrome but fails in IE7.
The failure seems to be the $SESSION variable. Using this code the alert works but fails on the "the string" statmement..
function checknums(){
alert("Here");
thestring=document.'.$SESSION["formname"]. '.member.value;
but fails on this statement indicating the $SESSION failure.
function checknums(){
alert("formname="+$SESSION["formname"]);
thestring=document.'.$_SESSION["formname"]. '.member.value;
Can anyone Help?
BYW, there is no "error on page" notice when calling the form or calling statement.
TIA for any ideas,
Dick Deeds

You can't mix Javascript and PHP together. It could be that the other browsers are being more forgiving with the name of the form.

You need to tell PHP to echo out the variable.

function checknums(){
alert("Here");
thestring=document.'<?php echo $_SESSION["formname"];?> '.member.value;

To elaborate further:

PHP is a server-side language. That means that when your server gets a request for a page, the PHP parser evaluates and executes all PHP code in the script. The resulting output is then sent to the browser to parse and render. Javascript is a client-side language, meaning it's part of the data that gets outputted for the browser to render.

I should have specified that this is in a javascript & Ajax function. Work OK in 5 of 7 calling programs but fails in 2.
Still not resolved.
