pdf manipulation

[Chris Mosser]

I have a client who would like to host a PDF on his site, but make it so
that each individual that downloads it has to open it with a separate
username and password. My question is if any php classes or libraries have
the capabilities to load an existing PDF into memory and basically add in
the login portion of it dynamically. Or, if anyone knows of a 3rd party
executable that can handle this, that would be great too.

thnx,

Where are the usernames & passwords maintained ?
Just place the pdf in its own subdirectory and protect that directory with
the web server.

my client wants the people who download it to have to provide a password
when they try to open the file on their own computer...to help cutdown on
piracy

Well then, the PHP group cant help. Looks like you are buying software.

That won't stop piracy. Take a look on whatever napster clone /p2p
sharing network you like, and you'll find plenty of PDFs called things
like:

I believe the folks at http://www.phparch.com/ do that with their
publication. Maybe drop a line in that direction to see if you can get
answers.

I know, but it's what my client wants to do. I think I found a way using
pdflib, but my testing server is using an older version the from the pdflib
docs that I read. If anyone is using a newer version of pdflib (5.0+ I'm
guessing) can you please try this:

$pass = $_POST['pass'];
$pdf = pdf_new();
pdf_open_file($ pdf, "some.pdf") ;
pdf_set_paramet er($pdf, "userpasswo rd", $pass);


I get an unknown parameter error but I am wondering if its just because my
server has pdflib 4.x.x and that parameter was not available then.
according to the pdflib manual, the parameter does exist.

can anyone help?????/////

Well, make the password their credit card number (or some other similarily
sensitive info) and watch that problem vanish!

book_password_i s_MC-283791882738821 0-EXP-0907.pdf, anyone?
