Re: PDF and FDF

Hi List, Answering my own question... I found this user comment at php.net/pdf_open_file. As you can see is dated feb 2002 (kind of old) Is this still true? Does anyone knows gbl@bso2001.com? Help! =) Thanks. Cesar gbl at bso2001 dot com 19-Feb-2002 08:30 Appending to PDF files: plainly, you can't. PDF files have an internal structure that would get corrupted by just appending to the file. You'd need to parse the PDF, create a new PDF and mix your additions with the old PDF. Just creating a new one should be *much* easier. Reading back the results: do a fopen() on the temporary file and use fgets() to read it. In your example where you just want to output the file, passthru should do the trick. Cesar Cordovez wrote:

Hi List! I'm using the following code to open a pdf form, place a picture and then save it. This is very new for me, and the code is giving me some errors like (Fatal error: PDFlib error: Empty document in c:\Inetpub\wwwroot\pdf_forms\dbtree.php on line 415 ). Can somebody help? (line 415 is empty, line 414 is "pdf_close") TIA.
