Hey!
I am facing a wired issue on orders, I can see some of my orders have duplicated line items, I asked customer and found that they only want one and the other is added by system and users did not noticed about that, though credit card are charged for double already i.e. for all quantity in cart.
I did a lot of research on that and still I am not sure how this happens and what is the fixes for this.
I am attaching some images so you will understand the issue.
See how it looks on order panel.

When I check my oc_cart I can see there are few customers with same product_id on database, see attached image.

This is how oc_order_product look
https://prnt.sc/q1b9t1
I am not sure why this duplicate line items on my store and how can I remove or prevent this.
How it can be possible? I am using latest version of OC Version 3.0.2.0
This make us a lot of troubles , I need to fix it ASAP.
Thank you in advance.

It is not possible according to default behavior. It appears your other modules is causing it. What other extensions you are using related to cart products.

This is possible with default behaviour when customer and guest carts are merged, that logic is not stable.
Problem has been reported before, I had it myself.

There is no other modules except default ones, I cleared cache, session tables etc. though this issue comes again, not sure when and how this possible.. I need to fix this.opencartmart wrote: ↑Mon Nov 25, 2019 3:47 amRegarding cart product duplicity, i.e. https://prnt.sc/q1b5tm

@letxobnav I just tried your mentioned case in OC v3.0.2.0, and it merged quantity correctly for me instead of creating duplicity though the scenario was very straight forward. Maybe I did not follow the case you are referring to.
@jainyuvraj_opencart as letxobnav said it is possible. Maybe there is a case, I don't know about it. Perhaps that special case is occurring to you as you don't have any other extensions. I will try spending some more time and let you know if I get anything.

The problem is that the merging of the carts is coded in the construct of the cart class and is also executed with ajax calls which can collide with normal processing resulting in duplicates also enabled by the fact that there are no meaningful primary keys defined.
Placing that merging code in the construct is not only a waste (executed on every page load) but also causes these issues.
Solution is to move that code to a function and only call that when a customer logs in (merging guest and existing customer cart) or signs up (assign customer id to the guest cart).
I will try to find my post on that a little later.
