I want to include my forum into my main site,How can I do it?

Try Iframes and the <?php include(“forum.php”); ?> tags

I have tried Iframes and the <?php include(“forum.php”); ?> tags. Both work but the problems with the iframe is it only works by width=”” and height=”” but not =”100%”. The Include tag wont open in my mainsite but only links to the forum when you click on a topic or thread. What is the best solution so that the forum is in my mainsite and stays there once you click on a topic or thread??

No, any extension should work.

An include won’t work as everything probably has relative paths. A frame would just be stupid.

I think you should either do a redirect or put the entire forum up one dir. i.e. in the root

u can not redirect with the use of frame.

yes, You can do an html redirect with the <meta> tag or a php redirect with the header() function.
