Products Problem

Hi everyone, I would like to put 1 product on sale, and make sure that it can be put in the cart only 1 time and not in unlimited quantities, how can I do it? I put quantity 1, but even though there are 1 items, the option allows you to put that item in the cart infinite times

Did you check the marketplace ?

Etc etc etc

Or the forum

Using google is usually better than the forum

In future please follow the forum rules. A minimum of OC version is always required

If you are using OC4 in any version it is not recommended for production sites. Use OC 3.0.4.0 which is stable.

hi my oc v is 3.0.4.0

Do I have to pay for a module to make the basic maximum and minimum function work?

If I say that there are 3 products available, it still makes me add that same product infinitely, why? I also set it to subtract from the stock, but nothing

My opinion doesn’t matter but I if it is not viable for developers to create modules then you will be paying for commercial support.
Maximum is not part of Opencart default.
You could hard code it I suppose. Search google maybe someone has asked and someone answered or maybe stackoverflow.com
Maybe if you check the marketplace you will find something free.
Minimum works fine on default opencart as does stock reduction.
If you have extensions or theme you have not mentioned maybe that is the issue.

Maybe provide more information, screenshots, website and any error logs.

It shouldn't let you order more than 1 though?

By default, OpenCart does not prevent users from adding a product to the cart in quantities exceeding the available stock. However, if "Stock Checkout" is disabled, a warning message will appear on the Cart Page, notifying users that the desired quantity is not available. Please refer to the screenshot attached.

Stock Checkout is a feature in OpenCart that, when enabled, allows customers to purchase more than the available stock quantity. If you wish to restrict users from ordering beyond the available stock, please ensure that this feature is disabled in your store settings.

Please follow the below steps to check whether the "Stock Checkout" is enabled or not on your store:
1. Go to System -> Settings from the left menu.
2. Edit your store. Go to the "Option" Tab.
3. Search for Stock Settings on the Page and disable "Stock Checkout".
