HI guys
I'd like to display another prodcuts name and link in every prduct detailed info page ( it is represented by previous and next )in the page. how can i do it ? i will display the previous and next products like this:
previous: product name 1(hyper link)
next: product name 2(hyperlink)

Turn function on from the admin
For the productlisting pages
admin > config > productlisting >Prev/Next Split Page Navigation (1-top, 2-bottom, 3-both)

for the Product info pages
admin > config > productinfo > Previous Next - Navigation Bar Position
and other settings for this

Thanks Kobra
I would like to add some code in the tpl_product_info_display.php file to show the previous/next products name and link at the bottom of the production info page. I don't know how to add the code inside this file.
Could you help?
Thanks in advance.

I take it that instead of the button "next" you want the next products name???
As this changes for each one would need to do some crafty coding to "select" the next product name for display in place of/in addition to the button
There are coders that can tackle this or if really important to you you can post to the commercial help area
