For whatever reason, whenever I submit the form, it doesn't add the inputted data to the database. It was working before... Which I think is what's frustrating me the most. I came back to it a couple of hours later, and surprise! Not inserting new rows into the database. Perhaps there's a slight error I may have done subconsciously by accident? Nothing stands out to me, though. :(
