prodigitalson, I wanted to post this solution for you, just in case you were still curious about wanting to find an answer. It only works on PDF's optimized for version 1.5 (Acrobat 6.0), but it does work beautifully. It is an unofficial patch for Zend Framework 1.12.3 to fill PDF Form Fields. Site with the discussion and patch
NO INSTALLATION, NO OUTSIDE PROGRAMS, NO COORDINATES
First update your php.ini file with something like the following (note: i will have to change my .ini file on my actual web server when I upload these changes):
include_path = ".;C:\wamp\www\includes"
Just a note: I moved all of the library contents out from 'ZendFramework-1.12.3\library' folder into a folder called Zend: C:\wamp\www\includes\Zend just for the ease of referencing the library (which is all you need anyways).
Then in your php file (I used 'DIRECTORY_SEPARATOR' so that you can use it on a Win or Unix server and that I won't have to make any code changes depending on where my .php file is, I'll only have to make server configuration changes):
require_once('Zend'.DIRECTORY_SEPARATOR.'Loader'.DIRECTORY_SEPARATOR.'Autoloader.php');
$loader = Zend_Loader_Autoloader::getInstance();
$loader->registerNamespace('Zend_');
And then for the actual code use:
$pdf = Zend_Pdf::load('input-file-containing-form.pdf');
$pdf->setTextField('name', 'Someone');
$pdf->setTextField('address', '1 Main Street');
$pdf->setTextField('city', 'Cyberspace');
$pdf->save('outputfile.pdf');
Or as I did it for my purposes (I also included the code that I used to email my finished employment application and then delete the .pdf file so that it doesn't clog up my server: attach_mailer_class.php available here Copyright (c) 2006, Olaf Lederer):
// Write $_POST form data to associative array
foreach ($_POST as $key => $value) {
$NameArray[$key] = $value;
}
// Path to PDF application fillable file
$pdf_path = dirname(__FILE__) . "\\docs";
$pdf_filename = 'employment_applicationJBzend.pdf';
$pdf_file_path = $pdf_path . "\\" . $pdf_filename;
// Path to PDF application file save location
$result_path = dirname(__FILE__) . "\\results";
$result_filename = ucfirst($_POST['first_name']) . ucfirst($_POST['last_name']) . $filedatetime . '.pdf';
$result_file_path = $result_path . "\\" . $result_filename;
//Filling PDF fields | Example: $pdf->setTextField('position_applied_for', 'IT Manager');
$pdf = Zend_Pdf::load($pdf_file_path);
foreach ($NameArray as $key1 => $value) {
foreach($ExceptionArray as $key2 => $value)
{
if($key1 == $ExceptionArray[$key2]){
$boolSetText = false;
break;
}else{
$boolSetText = true;
}
}
if($boolSetText){
$pdf->setTextField($key1, $NameArray[$key1]);
}
}
$pdf->save($result_file_path);
//Create and send message using 'attach_mailer_class.php
$email = new attach_mailer($from_name, $from_mail, $mail_to, $cc = "", $bcc = "", $subject);
$email->text_body = $message;
$email->add_attach_file($result_file_path);
// $email->add_attach_file("ip2nation.zip");
$email->process_mail();
unlink($result_file_path);
If page no longer exists here is the patch for PDF.php (which if you don't know how to run the actual patch, basically you go through your PDF.php file and replace all of the lines that below have a '+' in front of them. You can find where they are by the location tag '@@ -202,6 +202,13 @@' which is right around line 200, then just copy and paste to replace the old code with the new):
