activating alternative style sheet with php
picayunish
I'm trying to activate an alternative style sheet by clicking on a
hyperlink.
The problem what I have is when clicking on the link, the page jumps to the
right chapter but it wouldn't activate the alternative style sheet.
The code is:
<head>
<link rel="stylesheet" type="text/css" title="basic page style"
href="style.css">
<?php
if ($style="vert1") {echo '<link rel="stylesheet" type="text/css"
title="vertical" href="vert.css">' ."\n";}
?>
</head>
<body>
<a <?php $style="vert1"; ?> href="#vert1">jgjglkgfd dkgjlkd</a>
some content
<h2><a name="vert1"></a>blah</h2>
more content
</body>

What am I doing wrong?

Ummm... PHP doesn't work like that. Here is a basic stylesheet switcher
for you. It assumes that you have a directory "styles" containing
"black.css", "white.css" and "red.css".
============================ example.php =============================
<!DOCTYPE whatever>
<html>
<head>
<title>Example</title>
<link rel="stylesheet" type="text/css" media="screen,projection"
<?php echo ' href="styles/' . $_GET['style'] . '.css"'; ?> >
</head>
<body>
<h1>Example</h1>
<p>The style you chose was <code><?php echo $_GET['style']; ?>.css</code>.</p>
<ul>
<li><a href="example.org?style=red">Red</a></li>
<li><a href="example.org?style=white">White</a></li>
<li><a href="example.org?style=black">Black</a></li>
</ul>
</body>
</html>
======================================================================
In short, if you want a user to interact with a PHP script, it has to be
with clicking links to reload the page, tagging on parameters at the end
of the URL; or via form submits.
One improvement to the above script would be to add a default stylesheet.

Thanx Toby.
It's getting late. I'll try it later of the day, so good night.

Dunno, it works great.

And how should you do that? With an if then else structure? Cause I like the
script, it's easy. I've once made one with an if then else to see if the
variable was filled but this one is easier (though it hasn't got a default
style).

Well, I *was* going to leave it as an exercise to the reader, but since
you asked:
============================ example.php =============================
<!DOCTYPE whatever>
<?php
$s = $_GET['style'];
if (!($s)) { $s = 'red'; }
?>
<html>
<head>
<title>Example</title>
<link rel="stylesheet" type="text/css" media="screen,projection"
<?php echo ' href="styles/' . $s . '.css"'; ?> >
</head>
<body>
<h1>Example</h1>
<p>The style you chose was <code><?php echo $s ?>.css</code>.</p>
<ul>
<li><a href="example.org?style=red">Red</a></li>
<li><a href="example.org?style=white">White</a></li>
<li><a href="example.org?style=black">Black</a></li>
</ul>
</body>

I noticed in a style sheet (e.g. style04.css) the following string
*{color:black;background-color:#FFC066;}
Why using the * and not e.g. body {color:black;background-color:#FFC066;} ?

8-) !
The php script (above) and a normal style sheet link works perfectly.

http://www.semi-conductor.nl/test/test3.php (a style sheet link + php
script & it validates :-D )
