How can I add an custom query to product_info?

[alexandresz]

Hello,

 

I need to create a custom query to display a message or an image in the product_info.php

 

It should check the content of the table I created in order to work.

 

Like this:

 

Let's say the value in the table says "blue" and I want to display a blue square image in the product_info page.

 

Thank you,
