How do i get new products and featured products centerboxes on product info page?

[Lanadearg]

I tried this code
1. to the bottom of file:
/includes/templates/your_template_dir/templates/tpl_product_info_display.php
2. below code

!--bof also purchased products module-->
<?php require($template->get_template_dir('tpl_modules_also_purchased_products.php', DIR_WS_TEMPLATE, $current_page_base,'templates'). '/' . 'tpl_modules_also_purchased_products.php');?>
<!--eof also purchased products module-->

Not work.
I don’t have folders “templates” in /includes/templates/classic/templates/tpl_product_info_display.php ;
You mention anything about these folders.
Now I think, I accidentally erased them?
I think that they were not there.

Amuse me ...

Make a directory:
/includes/templates/classic/templates

and add the file:
tpl_product_info_display.php

and add the code that I posted ...

What happens?

I did it. But still not working. I will find other ways. Thank you Ajeh!

Not sure what to tell you but the code still does not appear to be in your View Source ...

Go to the Tools ... Developers Tool Kit ... and in the bottom input box enter:
<!-- bof: include centerboxes on product_info -->

and select Catalog and click Search ...

What comes up?
