Answer 1

Remove the "action" attribute...

Answer 2

The action is usually the name of the php file. In this case, the file is called "source.php"
I couldn't get forms to work in Code Playground so, if you do, please let me know.

Answer 3

The submit button/post method requires you to refresh the page, something which I think Code Playground doesn't let you do.

Answer 4

It does not work

Answer 5
