Hi, I write from Italy sorry for my bad English.
I have an application written in PHP using FPDF libraries FPDI + to concatenate PDF files but for some files I get the error ‘FPDF error: Unable to find xref table’, I saw in the files of the two libraries and found the function called function error ($ msg) that contains the following statement “die (‘ FPDF error: ‘. $ msg);” that causes the error message: how can I change this statement so that my application in case of ‘FPDF error: Unable to find xref table’ go ahead without crashing? I am new to php … Thanks to all

Jaco, where in the code does FPDI look for the xref table? Thanks.

I had the same problem, any version I used didn’t work. Saving with PS CS5, AI CS5, then tried CS4 etc. nothing

What I did was:
made the file ready as a pdf, moved the file to a windows machine with cutepdf virtual printer installed and pretended I was printing the file. That created a compatible multi page pdf file, which it could read.

Hope it can help someone else, coz it took me 2 hours or so…

I was able to fix this by using Adobe Acrobat Professional v8 and going to “Document -> Reduce File Size” and then choosing something really old like “Acrobat 5.0 or Later”, then the error was fixed!

Hi guys,

I’ve had this error on certian files and opening with adobe pro and saving worked for some but not all. So I looked at the code and FPDI uses the first 100 bytes of the PDF file to look for the xref table. I changed this to be the first 200 bytes and it worked for all my files. I guess it could be that as Adobe Distillers change they put the demarcation of the start of the xref in different places. Using the entire file size would probably be best but will also slow the process down. There should actually be a better way of looking for the xref table.

I KNOW THE ANSWER

Use Adobe Acrobat Pro and covert or save your source file to pdf/a

PDF for some reason has changed up how the handle the xref table after version 1.4, and Setasign is charing to be able to read these newer compress version of the file, the paid version does work.

For my company it was not fessable to have everyone convert their files to 1.4 or lower but if this is an option for you you can open the pdf document, click print and change your printer to Adobe PDF, the click on properties. Under the Adobe PDF settings tab change the Default Settings to PDFA1b 2005 CMYK and this should solve your problelm.

I am not 100% sure what these differerent setting do but this worked as a initial fix.

Ok…feel a fool now, just read again through your previous posts and solved my problem (was the compression settings).

Thanks!
