A checkbox field has the form
|
| 2 |
Pepperoni <input type="checkbox" name="pepperoni">
|
| 3 |
If the user checks the box, then pepperoni=on is sent to the CGI program. Or you can add a value attribute such as value="ok", and then value=ok is sent.

Radio buttons are similar except that you typically put several of them with the same name field and the browser only allows one of them to be checked.
|
| 5 |
<input type="radio" name="topping" value="pepperoni"><br>
|
| 6 |
<input type="radio" name="topping" value="mushroom">
|

If the user checks mushroom, then topping=mushroom is sent to the CGI program.

Both fields allow an attribute checked, which makes the default value be on.
