IE6 and this code = headache

[sKunKbad]

I have been working on a CSS theme changer, which is done using mod_rewrite and a redirect. All is well in most of the browsers I have tried (FF2, IE7, Opera, Safari), but IE6 doesn't like it. I do admit, I am running a standalone IE6, so that could be the reason. I don't actually have access to a real installation of IE6, so it may not be a problem for "normal" IE6 users. Perhaps you could check it for me if you have a real installation of IE6.

 

First the rewrite rule (which is fairly normal):

 

rewriteRule ^style.css$ http://www.brianswebdesign.com/style.php [NC,L]

 

So when each page is looking for a stylesheet, they are actually being fed /style.php:

 

<?php
session_start();
$rose_theme = "rose_theme.css";
$blue_theme = "blue_theme.css";
if(isset($_SESSION['stylesheet'])){
$choice = htmlspecialchars($_SESSION['stylesheet']);
$styleChoice = $$choice;
}else{
$styleChoice = $rose_theme;
}
$style = file_get_contents($styleChoice);
header("Content-Type: text/css");
echo $style;
?>

 

There is a simple form associated with the user being able to pick the theme:

 

<form method="post" action="themeChanger.php">
<select id="theme_choice" name="theme_choice">
	<option value="blue_theme">Blue</option>
	<option value="rose_theme">Rose Garden</option>
</select>
<input type="submit" value="Change Theme" />
</form>

 

and then there is themeChanger.php, which is a redirect script:

 

<?php
session_start();
if(isset($_SERVER['HTTP_REFERER'])){
	$samePage = htmlspecialchars($_SERVER['HTTP_REFERER']);
}else{
	$samePage = 'http://www.brianswebdesign.com';
}
$theme = filter_input(INPUT_POST, 'theme_choice' , FILTER_SANITIZE_STRING );
	if ($theme == FALSE || $theme == NULL){
		$_SESSION[stylesheet] = 'rose_theme';
	}else{
		$_SESSION[stylesheet] = htmlspecialchars($_POST[theme_choice]);
	}
header("Location: $samePage");
?>

 

For some reason, IE6 just hangs when I test this on the production server. On my home computer, IE6 does fine. Any hints as to what might be wrong is appreciated. I'm also wondering if I am protecting myself correctly in terms of $_POST, $_SERVER, and $_SESSION variables.

to be onest ie6 is crap so not worth cheeking...........

 

according to the big boys in the sky use as little css or as simple for ie6...............

 

IT MIGHT HANG IN IE6 BUT REMEMBER IE6 WAS FULL OFF BUGS THERE HUNDREDS OF IE6 VERSIONS

 

DEFENTLY TO DO WITH CSS TRUST ME.....

[sKunKbad]

Yeah, I hate IE6 too, but if it were a simple fix I'd feel better about fixing it. The whole rest of the site looks normal and works in IE6.

[redarrow]

look it a huge story on it own, Post you css for the templates were have a look no promise.........

[sKunKbad]

While it may be a header issue for the incoming CSS file, there's no way the CSS itself has a problem. It validates perfectly. The XHTML also validates perfectly.

It may be that your modifying it right now, but it does not change themes in FF3 or in IE6

Yes, I have been working on it. It's working in my Mac FF3, but I haven't tried Win FF3 yet. Thanks for the heads up though.

[sKunKbad]

Well, I changed the fact that the stylesheet was being generated through php, and it's working for me in IE6.
