Adding a external file after the first post

How might you display a Google ad after the first post or anything you like? It is very simple. You just need to add the variable $loopcounter in the Loop. If the $loopcounter is less than or equal to 1, then include your option. Check out the code:

<?php if (have_posts()) : while (have_posts()) : the_post(); $loopcounter++; ?>

  // your loop

  <?php if ($loopcounter <= 1) { include (STYLESHEETPATH . '/you-file.php'); } ?>

<?php endwhile; ?>

<?php else : ?>

<?php endif; ?>

Pretty simple huh. Well in the $loopcounter line, you may change the include to point to any file or maybe a custom widget like so:

<?php if ($loopcounter <= 1) { dynamic_sidebar( 'Plus Post' ); } ?>

Or use your code directly in between the { & }.
