Is there any way to create a FDF file within PHP without using the dead FDF functions? I am aware that you can use pdftk
to create a PDF from an existing FDF file, but I need to create the FDF file first with one field value set.
A PDF conversion and form utility based on pdftk. Php-pdftk brings the full power of pdftk to PHP - and more. Fill forms, either from a XFDF/FDF file or from a data array (UTF-8 safe for unflattened forms, requires pdftk 2.x!). This class can be used to create and load PDF forms in FDF format using only pure PHP code. It can generate an FDF document from an associative array of form values. The generated document can be saved to a file. The class can also do the opposite, i.e. Extract form values into an associative arrat from FDF files. PDF forms (FDF) are documents with fields ready to be filled by an user using PDF reader program. FDF is a little different from regular PDF documents, but this class makes it easier to generate and process FDF documents using pure PHP code. PDF files can transfer plain/formatted text, images, hyperlinks, and even fillable forms. In this tutorial, we’re going to see how we can fill out PDF forms using PHP and a great PDF manipulation tool called PDFtk Server. To keep things simple enough, we’ll refer to PDFtk Server as PDFtk throughout the rest of the article. Using HTML forms to fill in PDF fields with PHP and FDF. Creating the PDF file. First, you need to have created your PDF form file. I do this using the form tools in Adobe Acrobat. Remember to name each field in your document, you will need those names later when you create the HTML form.
Or, is there a way to set one field in a PDF using PHP (skipping the FDF file creation) before allowing a user to download it?
For the heck of it, I tried creating an FDF file in PHP using fopen
- did not work. I also know there is a generate_fdf
operation within pdftk
, but this does not allow me to set a specific value, at least not that I can see.
Does anybody know what an answer could be? I am pretty stuck. Unfortunately, I have no control over telling the client to scrap the full PDF (and instead use a webform).

With PDFTK you need two pieces to complete the puzzle. First you need FDF with the data, and secondly an original PDF with appropriately named form fields. PDFTK merges the data into the PDF.
To answer the FDF question first check out this excellent article, http://koivi.com/fill-pdf-form-fields/ that also includes a method to help generate the FDF.
Once you have the FDF with your data you can use PDFTK's fill_form function
You can keep the document editable by using passthru() instead of readfile($temp_file) and outputting to stdout instead of a file name by using the 'output - ' parameter. Also important is refraining from forcing a document disposition. If you try to force a file download rather than opening it in the browser you'll end up with an uneditable and unsaveable mess.
example:
This will open it in the browser using the Reader plugin. You'll then be able to edit and print the filled form fields, but I still haven't figured out a way to save a copy with the changes. I'm currently chasing Adobe sales for other options.
As noted elsewhere, do not use PDFTK's option 'flatten'.
The original PDF must not include any passwords.

If I understand you correctly, you just don't want to use the FDF library in particular?
Have you tried TCPDF? See http://www.tcpdf.org/
If you want to use an existing PDF file as a template and only add some values, use the extending FPDI which extends TCPDF: http://www.setasign.de/products/pdf-php-solutions/fpdi/

i want to extract the available fields as an array from a fillable pdf.
an array like: array('firstname','secondname','address');
i do not need the values for those fields, if they are filled.
what is easiest way to do that using PHP?

under online documentation for 'fdf_next_field_name' the following example is given that you can modify to store the field names into an array
I upvoted Murray's answer because her was in ernest and I am pretty sure that he is right pre php 5.3
Sadly, pecl fdf is no more.
Thankfully, one 'noah' made a comment on the php documentation with a preg_match_all regex solution to the problem. Included here with slight modifications for clarity. Long live noah.
I expect that someone will get fedup with the lack of true fdf support in php and fix this.
Since we are all probably after the same basic workflow if you are reading this question, then you should know that the basic workflow that I am following is:
- download normal pdf form.
- use libreoffice to make it a pdf form with named fields.
- use pdftk to turn it into a fdf file
- use this function to figure out what values the form needs.
- populate a flat php array with the correct variables defined (from db/whatever)
- use pdf_forge to create a new fdf with the values pre-filled
- use pdftk again to create a new pdf from fdf+original-pdf with the variables (from db/whatever)
- profit

The html query string, from the pdf file, is put into the variable $q_string. It is then parsed into an array called $pdf_array. $pdf_array holds all of the keys and values. Then array_keys() is used to put all the keys into $pdfkeys as you wanted.
I had come here looking how to read pdf values to put into a db, and finally after some more poking around came up with the above. Hopefully meets some people's needs. xfdf can also work, but you will need to parse as xml then -- this was simpler for me.
I get a normal post from PDFs submitting to my server, but not in the $_POST array. You just have to parse it from php://input:
