How To Display An 'Advertisement' Post Between Blog Posts?

Hi,

I'm trying to set up my blog so that it displays an 'Advertisement' post in between blog posts... ideally after every 2 posts, or something like that.

Obviously I would like the advert to appear automatically, without me manually having to make a post after every 2 posts.

Ideally it would work like it does on this website (scroll down about 2 or 3 posts until you can see the advertisement).


Does anyone know of a simple way of doing what I want? Would there be a plugin suitable to use?


Thanks for any help

 

This works for the default index.php:

<?php if (have_posts()) : ?>
   <?php $post_count = 0; ?>
   <?php while (have_posts()) : the_post(); ?>
      <div class="post" id="post-<?php the_ID(); ?>">
      .....
      </div>
      <?php if ( ++$post_count == 2) { ?>
         <!-- advertisement code here -->
      <?php post_count = 0; } ?>
   <?php endwhile; ?>

Code (markup):

Thanks for trying to help but thats not the kind of thing I want...

I want to display a special "advertisement" blog post, so that my readers know that its a sponsored blog post.
This is a screenshot of the kind of thing I want...

I didn't bother looking at the website because I thought I understood. Oh well...try this then:

<?php if (have_posts()) : ?>
   <?php $post_count = 0; ?>
   <?php while (have_posts()) : the_post(); ?>
      <div class="post" id="post-<?php the_ID(); ?>">
      .....
      </div>
      <?php if ( ++$post_count == 2) { ?>
         <div style="height: 320px; padding-top: 5px; margin-bottom: 20px; background-color: #EFEFEF">
            <h4>Advertisement</h4>
            <div style="margin: 0 0 20px 80px;">
               <!--- advertisement code here -->
            </div>
         </div>
      <?php } ?>
   <?php endwhile; ?>

Code (markup):

The style will need adjusting if your advertisement is a different size, and also if your post column is a different width.
