How to make a dynamic CSS Style Sheet

[The Little Guy]

It's very simple.

 

Basic

 

Add this at the beginning of a PHP file

<?php
header("Content-type: text/css");
?>

 

under that, place your CSS, (you can also use PHP)

 

in your HTML, place this (change your href to you style):

<link rel="stylesheet" type="text/css" href="themes/default.php">

 

Advanced

The second way, is only so your href doesn't contain a php extention.

 

In an .htaccess file place this:

Options +FollowSymlinks
RewriteEngine On
RewriteRule themes/default.css themes/default.php

 

Now your CSS can look like this:

<link rel="stylesheet" type="text/css" href="themes/default.css">

 

basically all it does is redirect the user to the PHP file with out them knowing.

Or just configure .css files to be handled by PHP. What is this post for anyway?

Just information I felt like sharing.

 

I would also like to add:

 

<?php
$value = 'something';
?>
<link rel="stylesheet" type="text/css" href="themes/default.php">

 

if you try to use $value in themes/default.php it will not be set. That is the same with "include[_once]", "require[_once]" your css file will not inherit any code from the previous file.

Better check up on your PHP...

 

file1.php

<?php
$var = 'foo';
?>

 

file2.php

<?php
include 'file1.php';
echo $var; // output: foo
?>

 

It's not the same as require and include.

That isn't what I meant, I know that will work, but if you do this:

 

file1.php

<?php
$var = 'foo';
?>
<link rel="stylesheet" type="text/css" href="themes/default.php">

 

themes/default.php

<?php
header("Content-type: text/css");
echo $var; // nothing gets output
?>

 

then in themes/default.php echo $var, nothing will echoed out since it is a separate request to the server.

I don't know what you mean, only what you say. After saying what you said above you said:

 

That is the same with "include[_once]", "require[_once]"

OK, try this:

 

file1.php

<?php
include 'file2.php'
?>
<link rel="stylesheet" type="text/css" href="themes/default.php">

 

file2.php

<?php
$var = 'foo';
?>

 

themes/default.php

<?php echo $var; ?>

Dude, I know. In fact it's pretty obvious. But you said it's the same when including files. It isn't.

[The Little Guy]

Its obvious to you because you know PHP, but what about those who don't, they may not have known that.

 

I tried to do that, and like 5 seconds later realized that the CSS file was a separate request to the server, so included files and variables didn't get passed from file1.php to my css file.

HTTP is a stateless protocol. You are making two requests. I.e. obvious. Web developers should have knowledge of the HTTP protocol as well in order to be good developers. If you need to do that then use cookies or sessions.
