Has Purchased / Already Bought Indicator for OC 3

Brief Description: This module displays information to authorized buyers on the product page about whether they have previously purchased this item. This increases customer loyalty and helps them make purchasing decisions.

Key Features:
Automatically checks whether an authorized user has purchased a given product.
Easy installation via the OCMOD modifier system in a single XML file.
Optimized direct SQL query to the database for fast operation without overloading the server.
Easily customizable: if necessary, you can change the HTML code for the message output in your theme's template file.

Implementation Features:
The module is an OCMOD modifier that does not modify core files.
Instead of a model, a direct SQL query to the order_product and order tables is used, ensuring accuracy and high speed even with a large number of orders.
The module is multilingual: you can easily add your own translations.

Frequently Asked Questions (FAQ):

Question: Information is not displayed on the product page.
Answer: Please ensure you are logged in to the store as an authorized user. The module does not work for guests. Also, check whether the modifications have been applied (Refresh button in the Modifications section) and whether the Twig cache has been cleared.

Question: Does the module work on my custom theme?
Answer: In most cases, yes, but if your theme has a heavily modified product.twig template structure, a minor adjustment to the search expression in the modification file may be necessary.

Question: Will the module account for returned or canceled orders?
Answer: Yes, the current version considers an order successful if it has an order_status_id > 0. You can easily change this condition in the SQL query in the modification file to, for example, exclude order statuses with returns.
