php relative links?

chucklarge

Hi,
I am trying to create a template that will work in a directory of a site, but the links are causing me trouble. I know that using relative links is faster compared to absolute links.

The problem is all my relative links break when i move the template to a new directory.

I have tried using $_SERVER['DOCUMENT_ROOT'] in the href but that creates an incorrect link.

How can i make realtive links in php from say the doc root?

Thanks,
Chuck

incorrect how? post some code showing exactly how you are constructing your links.

hi, ok this is waht happens.

my site
www.orderbuttons.com

this is my docroot
/www/www.orderbuttons.com/public/htdocs/

this the link that i want
<a href="<? echo $_SERVER['DOCUMENT_ROOT']; ?>/rss/viewall.php">test</a>

so that link could be in an html file in the root dir or it could be in any folder

but instead of it taking me to
http://www.orderbuttons.com/rss/viewall.php

it tries to take me here

http://www.orderbuttons.com/www/www.orderbuttons.com/public/htdocs/rss/viewall.php

echo '<a href="http://' . $_SERVER['HTTP_HOST'] . '/rss/viewall.php">test</a>';

Hi,
But that resolves to an html absolute link. I am trying to find a way to make php dynamic relative links, so an http request is not made.

an HTTP request always made, regardless of how you code your links. the basic premise: you've got a client and server. the client makes HTTP requests, the server spits back HTTP responses. thats' the www in a nutshell.

the example i posted is an easy way to make your code portable to disperate servers since the $_SERVER['HTTP_HOST'] var will be set for that domain.

well I guess i didn't mean to say that relative links didn't cause http requests. It was always my understanding that relative links were faster and so that was why i was looking for a way to make dynamic relative links.

thanks,
