Redirect quantity button when value = 0

First off I would love to thank you for creating this plugin, I have had a nightmare as a complete coding noob trying to upload the code and running around the internet and this has been the best option I was able to find after days of working on it.

I would like to ask if you could help me with a solution, when I go to checkout on my site and click the X button it redirects to the homepage which is great, yet when I click the – increment button to 0 it keeps me on the same page, I would love if you could help me add some code to the plugin that could either:

– Redirect me to homepage if quantity = 0

– Or create a code which restricts the quantity button to not go below one.

This would be a great help thank you so much in advance,

Jquarn Nelson.
