Inventory widget: prevent two submissions at the same timeAsked by Alen_Lin on March 25, 2016 at 05:06 AM
I have created an order form Inventory Widget to manager the available quantity, but I found a logic problem.
The available quantity 2 less.
userA and userB login the form and same time to fill-in the form
The available quantity 2 less display both userA and userB screen, then userA and userB can submit the order form without any error.
From backend report I got extra order, it's possible real-time double check the actual available quantity and display warning message before submit the order from ?
quantity check how order form problem style size
Thank you for contacting us. Can you also try it with the Appointment slots widget instead of the Inventory Widget? At that time, it will work properly. However, you need to space out between number and curly brace as you see below.
Please, test it on your side and let us know the result.
Thanks for your prompt response, I have do the testing in my form, but the Appointment slots widget can't meet my requirement.
The Inventory widget can fully meet my requirement but have some problem link my previous mention.
In my thinking is possible to design an function when user select or type quantity of the Inventory widget can real-time query the backend DB again to get the actual available quantity?
