I'm trying to make a booking site for students to book lab appointment times. Here's a brief overview so you know what I'm trying to achieve.
This website is to interact with my networking device in the back end (you don't have to worry about anything dealing with networking). This is done via shell scripting. I need to be able to call and execute a shell script in the back end and this is where I need your expertise.
I currently just have the site up but I have no functionality to this site, such as the booking and payment process. Attached, I have described in details as to how I would like this to be.
