HTML 5 - Store Counter that switches item to "sold out" after a certain number of purchases / clicks Options

[bigmowebsites]

Hello WDG Community-

I am in the process of creating an HTML 5 website for a friend - the site is coming along nicely, however I am struggling with one specific thing; my friend wants a feature implemented where the system will count how many items are sold, and then once the item is sold, it will no longer let the item be purchased. For example -
My friend has 10 shirts he wants to sell. Once 10 of them have been sold, is there a way to make the button non clickable until the item is back in stock? I think this requires a server to be implemented - if so I can try to download a virtual server on my PC.

Thanks in advance, any help is greatly appreciated

We were planning on just using Paypal's easy buttons to handle the transactions. I implemented a "add to cart" button for each item. https://www.paypal.com/buttons/

I didn't try to create a button code, but I suppose it creates a link to Paypal? In that case it might be tricky to also run a counter script on your own server in a reliable way --in particular, if the user cancels the Paypal payment your counter has still registered it as a purchase.

It's better if the counter only runs after the payment has been made. For example, if Paypal also creates a redirect back to a Thank You page on your own site (does it?) maybe you could let a PHP script on that Thank You-page update the counter file.
