You can "pre-initialize the values by using a hidden field. That way if
the checkbox isn't checked, the value from the hidden field will get
passed back. If it is checked, you get the checked value:

<input type="hidden" name="t[0]" value="0">
<input type="hidden" name="t[1]" value="0">
<input type='checkbox' name='t[0]' value='1'>
<input type='checkbox' name='t[1]' value='1'>
