[PHP] Re: problems trying to use PHP to choose CSS

Just a few minor notes: I was able to keep the echo EOD statements which I prefer for this particular implementation, and I kept form action=$PHP_SELF method='post' so that it would pass validation... (missing an 'action' was causing an error). That said, it was Hugh's PHP code that took this from being a thought I had to actually working. My thanks to him.

[PHP] Re: problems trying to use PHP to choose CSS
I am trying this method: Register a global variable ($CSS) using a FORM.
[snip]
I wonder if I am not doing something stupid/overlooking something obvious,
but I am very new PHP so that is possible.
// in my global PHP file
// Now what I am trying to do here is set a default that should ONLY be
// used if the $CSS variable is NOT already set
if (!isset($CSS))
{
// if it is not set, then and only then set it and define it
session_start();
session_register(CSS);
$CSS=global;
}
1. session_start() should called every time,
ie not inside a conditional clause.
2. I'm not sure that giving the form-return value
and the session value the same name is a good idea.
3. I think a lot of the double-quotes in your echoed
text were screwing things up.
Try something like:
?php// HEADER
session_start();
// new session? set default value
if (!session_is_registered(CSS)) {
session_register(CSS);
$CSS = global;
}
// setting changed by form? update session value
if (isset($newCSS))
$CSS = $newCSS;
?
