I usually place a hidden field with the same name as the checkbox
field before the actual checkbox field. I store my 'false' value in
there. If the checkbox is checked the hidden field is overridden.
<?php
error_reporting( E_ALL );
if( isset( $_POST[ 'submit' ] ) )
{
echo '<pre>';
print_r( $_POST );
echo '</pre>';
}
echo <<<EOF
<form method='post' action='$_SERVER[PHP_SELF]'>
<input type='hidden' value='0' name='blah'>
<input type='checkbox' value='1' name='blah'> Blah?
<input type='submit' name='submit'>
</form>
EOF;
?>
