You don't need to do that at all. The trick is to put:
<label><input type="checkbox" value="1" name="pdfcover"/> Cover</label>
<input type="hidden" value="0" name="pdfcover" />
If the checkbox is selected, the browser sends both values to the
server: pdfcover=1&pdfcover=0
But request.pdfcover gets the first value it sees, 1.
If the checkbox is unselected, the browser sends only the hidden value:
pdfcover=0, so request.pdfcover will be 0.
This is how the checkbox display of object properties is implemented as
well.
But yes, displaying the PDF options is something that I wanted to do as
well, just that I never had the time for it.
