A simple Magento extension that checks a simple product's stock quantity upon saving and updates its stock status. If the simple product belongs to a parent configurable product, the extension also checks the stock quantities of the other associated simple products, and updates the stock status of the parent configurable product accordingly.
Install using colinmollenhour/modman.
Most of my repositories posted here are projects created for customization requests for clients, so they probably aren't very well documented and the code isn't always 100% flexible. If you have a question or are confused about how something is supposed to work, feel free to get in touch and I'll try and help: info@mobweb.ch.
