    IMPORTANT:

    If you handled the FDF POSTs via $HTTP_RAW_POST_DATA as in user contributed scripts above, it's good to know that once you decide to rebuild PHP with FDFToolkit support, $HTTP_RAW_POST_DATA will be undefined.

    Good news - $HTTP_FDF_DATA _will_ be defined instead. (Look at the example above).To get the user contributed scripts working in both plain PHP and PHP+FDFToolkit use

    $HTTP_RAW_POST_DATA . $HTTP_FDF_DATA

    where $HTTP_RAW_POST_DATA mentioned.

    The code suggested by greg@... and adam@... is extremely helpful, but I've found out (the hard way) that unclosed parentheses within strings contained in the input array ($values in greg's code or $pdf_data in adam's) will cause Acrobat to issue an error to the effect that the file is corrupted. In other words, if there are strings such as "a) my first point; b) my second point" in the input array, the resulting PDF/FDF file will be considered corrupted by Acrobat. This apparently happens because all the field names in the structure of an FDF file are enclosed in parentheses.

    The solution I've devised is to escape all opening and closing parentheses with a backslash, which in turn means you need to escape all backslashes. The code below does all that.

    Erik

    ---------------

    function output_fdf ($pdf_file, $pdf_data)
    {
    $fdf = "%FDF-1.2\n%????\n";
    $fdf .= "1 0 obj \n<< /FDF ";
    $fdf .= "<< /Fields [\n";

    $search = array('\\', '(', ')');
    $replace = array('\\\\', '\(', '\)');
    foreach ($pdf_data as $key => $val)
    {
    $clean_key = str_replace($search, $replace, $key);
    $clean_val = str_replace($search, $replace, $val);
    $fdf .= "<< /V ($clean_val)/T ($clean_key) >> \n";
    }

    $fdf .= "]\n/F ($pdf_file) >>";
    $fdf .= ">>\nendobj\ntrailer\n<<\n";
    $fdf .= "/Root 1 0 R \n\n>>\n";
    $fdf .= "%%EOF";

    return $fdf;
    }

    Changing the

    session.cache_limiter

    directive in the php.ini file to 'private'

    seems to resolve the issue with sending fdf data and session headers at the same time to Internet Explorer.

    If you get the new fdftkv5.tar.gz from adobe's site (per the link above), you'll get some totally new spacing and capitalization of files. To make the current 4.3.1 configure, you need to do a few things.

    untar fdftkv5.tar.gz into /usr/local
    cd /usr/local
    #for ease of use
    ln -s FDFToolkit\ for\ UNIX fdf

    cd fdf
    ln -s Headers\ And\ Libraries HeadersAndLibraries

    #may need to modify the following for your OS
    ln -s LINUX linux
    cd linux/C
    ln -s LIBFDFTK.SO libfdftk.so

    cd ..
    cd ..
    ln -s Headers headers
    cd headers
    ln -s FDFTK.H fdftk.h

    And that should get you going... and to whoever is maintaining the configure script, please be aware there are changes in the FDF Toolkit.

    I have tried to use the scripts above by adam and Toppi and I have been unable to get them to work unless I save the generated fdf file and then open it manually in acrobat.

    Use "Yes" instead of "On" to populate checkboxes.

    If you can't get the php_fdf.dll working in PHP 5.3 on Windows, one possible work around is to use the activeX version from the "FDF Toolkit for Windows" from the Adobe website. Here is part of a class I built for one of my projects.

    <?php
    class FDF{
    public     $NormalAP = 0;
    public     $RolloverAP = 1;
    public     $DownAP = 2;

    protected     $fdf;

    public function     __construct(){
    $com = new COM('FdfApp.FdfApp');
    $this->fdf = $com->FDFCreate();
    }
    public function     setFile($fileName){
    $this->fdf->FDFSetFile(str_replace(' ', '%20', $fileName));
    }
    public function     setValue($name, $value){
    $this->fdf->FDFSetValue($name, $value, true);
    }
    public function     setAP($field, $whichFace, $fileName, $pageNumber){
    $this->fdf->FDFSetAP($field, $whichFace, $fileName, $pageNumber);
    }
    public function     savetoFile($saveFileName){
    $this->fdf->FDFSavetoFile($saveFileName);
    }
    public function     close(){
    $this->fdf->FDFclose();
    }
    }
    ?>

    Do not use version 6 of the fdftk.dll (windows) with PHP4.3.4, use the one that comes with PHP.

    If you use the newer DLL fdf_create will not return a valid handle.

    I tried a lot with FDF -> PDF and merging these documents...
    in my opinon xfdf is more handy than fdf... for those who'd like to try: feel free to use this little function to generate an xfdf document from an array.

    ToPPi

    function array2xfdf($xfdf_data, $pdf_file) {
    // Creates an XFDF File from a 2 dimensional
    // Array Format: "array ("key1" => "content1", "key2" => "content2");
    $xfdf = "<?xml version='1.0' encoding='UTF-8'?>\n";
    $xfdf .= "<xfdf xmlns='http://ns.adobe.com/xfdf/' xml:space='preserve'>\n";
    $xfdf .= "<fields>\n";
    // Loop -> Array to XFDF Data
    foreach ($xfdf_data as $key => $val) {
    $xfdf .= "<field name='".$key."'>\n";
    $xfdf .= "<value>".$val."</value>\n";
    $xfdf .= "</field>\n";
    };
    // XFDF "Footer"
    $xfdf .= "</fields>";
    $xfdf .= "<f href='".$pdf_file."'/>";
    $xfdf .= "</xfdf>";
    return $xfdf;
    }

    This is for users who are looking for a way to merge HTML form data with a PDF Form, then output the PDF Form with data populated in it, to a web browser.

    This is a pure PHP solution which does NOT require the FDF toolkit. Contributed by www.TUFaT.com

    <?php

    // the full http path to the PDF form
    $form = 'http://my_domain.com/my_pdf_form.pdf';

    function     create_fdf ($pdffile, $strings, $keys)
    {
    $fdf = "%FDF-1.2\n%????\n";
    $fdf .= "1 0 obj \n<< /FDF << /Fields [\n";

    foreach (    $strings as $key => $value)
    {
    $key = addcslashes($key, "\n\r\t\\()");
    $value = addcslashes($value, "\n\r\t\\()");
    $fdf .= "<< /T ($key) /V ($value) >> \n";
    }
    foreach (    $keys as $key => $value)
    {
    $key = addcslashes($key, "\n\r\t\\()");
    $fdf .= "<< /T ($key) /V /$value >> \n";
    }

    $fdf .= "]\n/F ($pdffile) >>";
    $fdf .= ">>\nendobj\ntrailer\n<<\n";
    $fdf .= "/Root 1 0 R \n\n>>\n";
    $fdf .= "%%EOF";

    return     $fdf;
    }

    // Fill in text fields
    $strings = array(
    'date' => '10/17/2004',
    'full_name' => 'Joe Doe',
    'phone_num' => '123-4567',
    'company' => 'ACME Widgets',
    'amount' => 'USD 100.00'
    );

    // Fill in check boxes/radio buttons
    $keys = array('
    gender'     => 'male',//radio button
    'is_adult' => 'Off',//checkbox
    'urgent' => 'On'//checkbox
    );

    // Output the PDF form, with form data filled-in
    header('Content-type: application/vnd.fdf');
    echo     create_fdf($form, $strings, $keys);

    ?>
