I don't think you need to use the php init() function more than once.

in a way you're right...i think i have it poorly named.
however, that method needs to be constantly checked...so i do have to call it again and again

I've been making suggestions to solve specific problems in your code, while all along I should have been questioning the overall functionality. Unfortunately I haven't gotten a chance to look carefully at your code, so I'll just offer another specific suggestion.

Make sure your html is layed out in the following basic layout:

<html>
<head>
<script etc.>
javascript goes here
</script>
</head>
<body>
<form etc.>
php goes here
</form>
</body>
</html>

Don't put the body above the opening html tag.

Can you post the entire file you are having problems with? Then we might be able to find the error.

I don't see session_start(); anywhere.. Has to be at the top before anything is output. And i might be missing something but this line <?php $_SESSION['genericNewConfig'] = true; ?> will set the session variable to true. So when init() runs the variable will always be true.

the session_start() is done in the .php file.
and you're right, this line <?php $_SESSION['genericNewConfig'] = true; ?> will always set the session variable to true, but this is what i want when the createNewConfig() method is called.

Start by fixing all your HTML errors. The document needs to be like this:

DOCTYPE declaration here
<html>
<head>
Script/metatags/style/title tags here
</head> after this you can't have any more head tags
<body>
Here is where all the body goes
</body>
</html>

You can't have more than one each of these tags.
<html></html>
<head></head>
<body></body>

You can't call a php function from within javascript. What you can do, is have the *output* of a php function become part of your javascript.

When your page is requested by someone's browser, server will look at the file and first evaluate and execute all php code. The output of that will be *only* HTML, Javascripte etc. That is what is sent to the browser.

If you want some help, try expaining exactly what you want to accomplish with this and I can tell you how I would do it. I simply can't decipher what you're trying to achieve by looking at your code.

Ok thanks Exam.
I have a button called "CreateNewConfig" that when pressed will set the SESSION variable to true. It then needs to call the function checkStatus(), which determines the SESSION variable and if false, will disable the submit and cancel buttons, if true, will make them available. This checkStatus() method needs to be called more than once.
Does this make sense? Enough information?

Thanks in advance.

What you have described are some of the steps to accomplishing a given task, but what is the overall goal you have? If you need to register users or something, but you have some special requirement, that is what you need to describe.

My apologies.
The form starts of with a defaulted selection box and disabled save/cancel buttons. If the user selects the newconfig button, they are able to create a new configuration item, which will change the select box to a text box and make all fields on the form writeable, and make the save/cancel buttons availble to submit the form.
