I'd like to add "Add To Cart" buttons below each post on MULTI-POST pages. I thought I could enter something like this below the loop but it doesn't work...

PHP Code:

<?php
if (is_archive()) {
  echo '<div><?php echo do_shortcode('[eshop_addtocart]'); ?></div>';
  } else {
   echo ' ';
  }
?>

This part:

PHP Code:

<?php echo do_shortcode('[eshop_addtocart]'); ?>

Does work when I insert it via the Post Layout plugin but I can't seem to add it to the theme. What I was hoping to do was to make the buttons show below the abbreviated posts on those pages.

Thanks

p.s. maybe I don't even need the "else" part but I figured it couldn't hurt...
