Hope that makes sense!")* Hi, In the menu Products>Limits, you can create limits on purchases. So you can configure a limit for a product so that each users won't be able to purchase that product more than once (it won't even work with different orders). The only solution for them would be to create several user accounts. So I think it fits your needs. The downside though is that you need to create one limit per product. Because if you create a limit for all the products, then the users will only be able to purchase a product once and not anymore after that. You can read more about limits here: [ www.hikashop.com/support/documentation/2...limits-tutorial.html](https://www.hikashop.com/support/documentation/293-filters-and-limits-tutorial.html) So one solution would be to have a way to generate the limit in the hikashop_limit table each time a product is created. Supposing that Calcbuilder generates the products via the save function of class.product of HikaShop, then you can interface a mass action with an INSERT MySQL query to automatically create the entry in the hikashop_limit table. So it's quite simple, even without coding knowledge. Or maybe Calcbuilder offers some kind of PHP code execution capability where you could have it run the MySQL query for you ? Otherwise, you could always create a plugin to interface with the add to cart process to check that the product being added to the cart by the current user is possible or not based on the previous orders of the user and if not, cancel the add to cart. That's for example something we do in the 'cart reservation' plugin: [ www.hikashop.com/marketplace/product/208...art-reservation.html](https://www.hikashop.com/marketplace/product/208-checkout-cart-reservation.html) In it, we check that the products being added to the cart are not already reserved by other users in their carts and if that's the case, we cancel the add to cart with the appropriate message. So it's the same mechanism, but with another condition. Of course, in the case of a custom plugin, you have more leeway to have it work exactly the way you want, but it requires a PHP developer to work on it...

I've attached a screenshot showing some of the PHP code that is creating the Hikashop products from Calcbuilder results. So, for instance, it uses the code $hk_quantity to limit the quantity of each "product" to three. I want to add a line of code that works on the "limit" you mentioned, and limit it to one. I tried just using $hk_limit, but since it doesn't work, I assume that's not right. Instead of $hk_quantity, what would I start that line of code with to ensure that the quantity on the created product is limited to one? - [ ![Screenshot2023-12-22at16-49-05CalculatorconfigurationExitLayoutResidentialChainLinkFence-FencePrice-Administration.png](/forum/attachment/58466) ](/forum/attachment/58466 "...nistration.png") [ ](/forum/attachment/58466?download=1 "...nistration.png") Please [Log in](/login?return=aHR0cHM6Ly93d3cuaGlrYXNob3AuY29tL2ZvcnVtLzMyLWNvbnRlbnQtY3JlYXRpb24vOTA3NDk4LWxpbWl0LWFsbC1wcm9kdWN0cy10by1vbmUtcGVyLWN1c3RvbWVyP3RtcGw9bWFya2Rvd24=) or [Create an account](/component/users/registration?Itemid=101) to join the conversation. - **[nicolas](/forum/user/63-nicolas "View nicolas's Profile")** - [![nicolas's Avatar](https://www.hikashop.com/media/kunena/avatars/resized/size144/users/avatar63.png?1793428657)](/forum/user/63-nicolas "View nicolas's Profile") - [ Offline](/forum/user/63-nicolas) Less More - Posts: 86320 - Thank you received: 14276 - - 2 years 10 months ago [\#357815](#357815) by [nicolas](/forum/user/63-nicolas "View nicolas's Profile") Replied by *[nicolas](/forum/user/63-nicolas "View nicolas's Profile")* on topic *[Limit all products to one per customer](/forum/32-content-creation/907498-limit-all-products-to-one-per-customer#357815 "Hi there, Is there some way to limit ALL products to one per customer?

And in this code, you have yet to create the product, and thus, the product is not yet known. As I said, the first thing is to check with the support of Calcbuilder to see what they recommend on how to proceed with this based on what I wrote previously.

So if customer wants to order another one same product, Hikashop cart notification plugin shows message for small time (defined in plugin) and disappears. So in my case user just sees that message for 1s and that's it. Is it possible to notify customer in different notification way in this case? Like the same way "The cart is empty" notification in bredcrumbs. Last edit: 2 years 5 months ago by [arnask](/forum/user/6752-arnask "View arnask's Profile").

Hope that makes sense!")* Hi, There is no option for this. However, it's possible with some custom coding. HikaShop provides javascript events, including cart.updated in order to process what the server-side returns after the user clicks on add to cart: [ www.hikashop.com/support/documentation/6...ocumentation.html#js](https://www.hikashop.com/support/documentation/62-hikashop-developer-documentation.html#js) The HikaShop cart notification plugin actually implements this event in order to display the notification box. It is done in the file plugins/hikashop/cartnotify/media/notify.js Also, since Joomla 4, it's possible to use javascript code to dynamically display error messages via the Joomla message system: [ joomla.stackexchange.com/questions/20579...mla-using-javascript](https://joomla.stackexchange.com/questions/20579/how-to-display-message-in-joomla-using-javascript) So, if you're a developer, you can combine all this to add your own error messages to the pages as needed.
