You don't. This is an HTML problem, not a PHP problem. A checkbox is only
included in the POST array when it is checked ON.
However, there is a workaround. Simply define a hidden field with the same
name as the checkbox immediately BEFORE the real checkbox, and assign it a
value of FALSE or OFF. Only one field with the same name will appear in the
POST array, so if the checkbox is not ON it will allow the hidden FALSE
value to pass through. If the checkbox is ON, then it will replace the value
from the hidden field.
