Can I add PHP code to each product in Marketpress?

I have “Tag This” plugin installed with a little modification. I am making it where logged in users hit a button and it adds a tag of their username to the post.

I have this working perfectly with posts, but now I need it on each “Product”.

Can I add php code to Marketpress to achieve this?

Here is the code I need to be on each product page:

<?php

if ( is_user_logged_in() ) { if (function_exists(‘wp_tagthis’:wink:) { wp_tagthis(); }

     else {

    

  }

} else {

  // display content for guests

}

?>

Thanks for the help!
