I am using the code below to regenerate order's downloadable product permission (including Bundle products), but this code is adding the same PDF multiple times in orders. Can anyone is able to help me to fix this issue?

Also in addition, is there any way I can check if PDF is added in order as a downloadable item then do not add them again within this code?

Can someone please assist with fixing this issue and ensuring that PDFs are not duplicated in the order?

• 1 Have you verified that wc_customer_has_download_permissions is giving correct results in each possible case? – C3roe Commented Mar 18 at 9:26
• 1 The function wc_downloadable_product_permissions has only 2 arguments (not 3): $order_id (integer) Order ID, and $force (boolean) Force downloadable permissions. So wc_downloadable_product_permissions can't target any specific product ID and needs to be used one time for each order. Note that the rule in stack overflow is one question at the time, not 2. – LoicTheAztec Commented Mar 18 at 9:42
• Hi @C3roe, yes this function wc_customer_has_download_permissions is working, but is setting same pdf file multiple times in one order when product type is bundle. – Avinash Patel Commented Mar 18 at 9:45

I have finally got an answer for this question, here below I am sharing full code if anyone want to use it, just make sure you run this code in batch like 01/01/2024 to 01/04/2025 then again for 01/04/2025 to 01/08/2025 to avoid heavy load on the server.
