PHP and Form data to PDF

Anyone know how to select checkboxes in PDFs using PHP?

<?php
require('fpdm.php');

$fields = array(
'forname' => 'Jon Dow', // text input: works
'mycheck1' => true, // checkbox: doesn't work! Also tried "true", 1, "1", "yes", "on", ... (with case-sensitive)
);

$pdf = new FPDM('template.pdf');
$pdf->Load($fields, true);
$pdf->Merge();
$pdf->Output();
?>

Checkboxes are a special-case thing in HTTP requests; if they are not checked, they are not part of the request. Some special tricks may be needed to provide a default value. I don't know what FPDM might be doing with the checkboxes, but it's certainly worth understanding how they work.

That helps. Unfortunately those notes are 5 years old :-(
Guess I'll have to get creative.

After a little more research, I found these comments in the most recent download. Since this is dated 2011 and it says that the "to do" list includes checkboxes as a future objective, it's probably not been done. Perhaps you can extend the class to add the form types, but I don't think it has the capability out of the box.
