How to limit number of order per customer for certain product? – Magento 1.9

I have a requirement in my website where the customer can buy a certain product only once. If they try to buy that again it should throw an error saying cannot purchase this again.

Please help me on this.

    If it is only one or few products like that – the best way in my opinion is to add attribute to customer and change it after product is purchased.

    Thanks for your question…

    Solution:-

    1- You’ve to create product attribute as Yes/No & by default, it’ll be No.you’ve to select as Yes for the product which you want to avail purchase only once.

    2- If a customer is logged in, then during Add to Cart if a product can purchase only once for a customer then before adding to cart(use observer here) you’ve to check if a customer already purchases this item if yes then you’ve to avoid
    Add to Cart else customer can add this to cart.

    3- If a customer is not logged in, in this case, it depends on you.

    There may be 2 cases:-

    a- Simply customer can be added to cart any item & after login, if a customer has added the restricted item(only once purchase) then you’ve to remove the restricted item from the cart if already purchased else vice versa.

    b- OR you don’t allow to Add To Cart(by an observer) restricted item if a customer is not logged in.

    Hope it’ll resolve your problem.
