So here we go! Coding! This is what programmers do.
You have started the course in an easy way: Scratch and Gamemaker. These programs help you to learn several ideas around programming like the results of changing settings and how to apply a bunch of conditions to an object. Very useful.
However, for programming on the web, you need to learn a bit of HTML first and then we will make a form and “handle” it with php.
Background and resources here at w3schools.com
Look at html forms and how the information gets to php.
