Wordpress random posts in front page

[Astaroth0803]

Hello

I’d like to have certain posts (defined by category, tag, whatever is best) to randomly appear among my usual blog posts on the Wordpress front page. To make it a bit clearer – I’d like to have these posts serve as random ads mixed with regular non-ad posts.

I was able to have ALL my posts appear randomly by inserting this line on top of my index.php file (found in one of the topics on the Wordpress support forum):

<?php query_posts($query_string . ‘&orderby=rand’) ?>

but I’d only like certain posts to behave that way.

 

Unfortunately I don’t know php, but it seems to me that the easiest way to achieve this is to have this in my index.php

<?php query_posts($query_string . ‘&orderby=rand’) ?>

only with the added condition that it applies to posts assigned to specific category/tag. Unfortunately I don’t know how such a condition can be added in php, so any help will be highly appreciated.

You can have a you look at my test page here http://athenagfx.com/philoxeniatest
