Trying to Post data to mysql database

Ok so I’m trying to post data to mysql database using an arduino uno ( WiFi shield) using the follwoing example from GitHub - bsalinas/POST-Arduino-Data: A simple way to send data from an Arduino and save it to a database (MySQL) over WiFi.. It works well with two columns in the database(yourdata and timestamp), but when I try to modify both the php & arduino code to post data on multiple columns, nothing happens. Also If i run the original code on the database with 3 columns instead of 2 as stated in the example (yourdata, timestamp) I get nothing as well.
