Hi,
You have three things basically:
- You can activate the "Display a contact button on the product page" setting in the HikaShop configuration to get a button to the contact form for that product. And you can create custom fields of the table "contact" via the menu Display>Custom fields to personalize the form.
- You can create custom fields of the table "product" via the menu Display>Custom fields. Then, you'll be able to fill these fields in each product edit interface, and then the content will appear on that right area automatically.
- You can edit the file "show_default.php" via the menu Display>Views to customize the look of the product page, including the right part. You'll find hikashop_product_right_part there.
And of course, you could have a combination of these. For example, some custom product fields to fill in some key unique to each product, and some code in show_default.php to get the data from the custom fields and use it to generate the link to where you want the customer to go.
