SMF Latest Posts

[monkeypaw201]

I did this as a favor for someone, but I figured I'd share it with everyone.. you know, spread the wealth.

This code simply reads the RSS feed that SMF outputs (of the latest posts) and returns it as a list (with the option to make it linkable).

The implementation technique can vary, you could include the file, or just copy and paste it into your page (~100 lines).

As a brief update..

A bug I found is that you will need at least two posts in your forum for this to work propery.

Also, if you get errors like this:

Warning: file_get_contents() [function.file-get-contents]: URL file-access is disabled in the server configuration in /home/XXXXX/public_html/lib/skins/XXXXX/frontpage_main.tpl on line XXXX

It means that your web hosting provider is a little paranoid with their PHP security, so you can use this code instead, which uses a different method of retrieving the information.

With smf isn't it easier to just use the built in features of ssi.php that is already installed with the board?

Here is the one from the westjetvirtual board,

http://www.westjetvirtual.net/forum/ssi_examples.php

if you have smf installed you should be able to get to it by - path to your forum/ssi_examples.php

I tried that, but it didn't work, it gave me a fatal error, and the skin didn't work.
