Form Demo
Questions:
Can you get data in both
$_GET
and
$_POST
at the same time? If so, how. If not, why not?
What happens if you leave a text box empty?
Can you "unselect" all the radio buttons? If so, how. If not, why not?
Can you select "Fred" and "Barney" at the same time? Can you select "Barney" and "Trumpet" at the same time? What's the difference?
What happens if you unselect all the check boxes?
How does PHP treat checkboxes differently when doing a POST than when doing a GET?
How can you tell which submit button was pushed?
