Populating PDF form fields with PHP - php

I am converting a classic ASP application to PHP.
In the Classic ASP app, we are programatically populating fields that have been created in PDF documents using a component called ASPpdf.
I need to reproduce this behavior in PHP, but need to know if PHP can populate PDF fields on its own or if any third party plug in is needed.
Is this functionlity posible in PHP with or without a plug in?
Thanks.
Note: I already have the PDFs created, I do not need to create the actual PDF. I need to grab a preexisting PDF with form fields, populate those form fields and then save that custom PDF.

This is the first google search result I got, is there a reason this doesn't work for you?

UPDATE
After reading a little further, this generates an FDF (which Acrobat can read). To generate an actual PDF you'll need to use this: http://www.pdflabs.com/tools/pdftk-the-pdf-toolkit/

The resolution to my problem was to use the same COM component I used in Classic ASP in my new PHP apps. The COM object give me tremendous control over PDF documents.
The component I use is AspPdf
<?php
$pdf = new COM("Persits.Pdf") or die("Unable to instantiate Word");
$pdfdoc = $pdf->OpenDocument( "pdf.pdf" );
$pdffont = $pdfdoc->Fonts("Helvetica-Bold");
$pdfdoc->Form->RemoveXFA();
$pdffield = $pdfdoc->Form->FindField("FirstName");
$pdffield->SetFieldValue("PHP Text", $pdffont);
$pdffile = $pdfdoc->save( "php.pdf" , false);
echo $pdf->version;
$pdf = null;
?>

It looks as though the pdftk PDF toolkit may be able to do this. Reading the manual:
fill_form < FDF data filename | XFDF data filename | - | PROMPT >
Fills the single input PDF’s form fields with the data from an FDF file, XFDF file or stdin. Enter the data filename after fill_form, or use - to pass the data via stdin, like so:
pdftk form.pdf fill_form data.fdf output form.filled.pdf

Pimcore how to create PDF and send via email

Anybody can give us a hint how to treat this best, if this can be achieved with „standards“ of pimcore?
Render a PDF with dynamic content and merge it with a PDF which has legal information.
Then send final pdf via email.
The PDF should be able to designed with HTML
You can use the Web2Print Documents to create and render the first PDF with dynamic content. To modify the PDF afterwards, you can hook into the PDF generation process (Pimcore 4 example):
\Pimcore::getEventManager()->attach("document.print.postPdfGeneration", function (\Zend_EventManager_Event $e) {
$document = $e->getTarget();
$pdf = $e->getParam("pdf");
Once you got that PDF, you can merge it with other PDFs like described here: Merge PDF files with PHP
Sending it via email should be easy at this point.

How to manipulate PDF files having scripts?

I have a PDF file with a form where you can enter some data and everything will be recalculated. The file has also some text fields I want to prefill with my own data from PHP.
I played with PDFtk. Unfortunately it is not working on my hosting provider and I can't install it there. And also even if it works, the scripting functionality of that form is gone after saving by PDFtk.
Do you know any good alternative to PDFtk or a method how to edit PDF files without loosing the embedded scripts?
The SetaPDF-FormFiller component (a non-free product of us) allows you to fill in PDF forms and also XFA forms with PHP:
// create a document instance
$writer = new SetaPDF_Core_Writer_Http('filled-form.pdf');
$document = SetaPDF_Core_Document::loadByFilename('form.pdf', $writer);
// create a form filler instance
$formFiller = new SetaPDF_FormFiller($document);
// get access to the fields
$fields = $formFiller->getFields();
// fill in the fields
$fields['name']->setValue('blackhatmario');
$fields['a']->setValue(123);
$fields['b']->setValue(321);
// ...
// save the filled document
$document->save()->finish();
In view to calculations in form fields it may be required to force the calculation at opening time by a simple document level javascript:
this.calculateNow(); // in Doc context

FPDF and PHP: Help merging PDF forms with text fields without losing text data?

I have PDF form files that I fill out dynamically with PHP using FPDM (the FPDF script). I can save them on my server no problem, and the text all looks fine in the PDF when I download and view in Acrobat.
My problem is: I'm trying to merge multiple PDF files together on the server so the user can download a single PDF document with several pages. I downloaded PDF Merger (http://pdfmerger.codeplex.com/) and got it merging the files together, but this causes the PDF form text to disappear.
Anyone know of a form-friendly PHP-based PDF merger that doesn't require installing anything (other than uploading libraries) to my server?
Code that works for merging but kills text in form boxes:
$pdfCombined= new PDFMerger;
$pdfCombined->addPDF('../forms/generated/16.pdf', 'all')
->addPDF('../forms/generated/19.pdf', 'all')
->merge('browser', 'mergedDoc.pdf');
The linked "PDF Merger" simply uses FPDI in the back. FPDI is not able to handle dynamic content as described here.
A pure PHP solution for merging PDF forms is the SetaPDF-Merger component (not free). An evaluation requires the installation of a Loader (Ioncube or Zend Guard). License owners will get access to the source code, so that no external library is needed. The usage is also that easy:
require_once("library/SetaPDF/Autoload.php");
// create a file writer
$writer = new SetaPDF_Core_Writer_Http("mergedDoc.pdf");
// create a new merger instance
$merger = new SetaPDF_Merger();
// add the files
$merger->addFile('../forms/generated/16.pdf');
$merger->addFile('../forms/generated/19.pdf');
// merge all files
$merger->merge();
// get the resulting document and set the writer instance
$document = $merger->getDocument();
$document->setWriter($writer);
// save the file and finish the writer
$document->save()->finish();

Convert HTML form data into a PDF file using PHP

I have been looking and testing this for a couple days now and was wondering if anyone could point me in a different direction. I have a very long job application HTML form (jobapp.html) and a matching PDF (jobpdf.pdf) that have the same field names for all entries in both the HTML form and the PDF. I need to take the user data that is entered in the form and convert it to a PDF. This is what I have gathered so far but don't know if I am on track:
Is pdftk the only viable 3rd party app to accomplish this?
Using pdftk would i take the $_POST data collected for the user and generate a .fdf(user.fdf) then flatten the .fdf on the .pdf(job.pdf). So irreguarless of where the fields are located on each document the information on the fdf would populate the pdf by field names?
I have been trying
http://koivi.com/fill-pdf-form-fields/tutorial.php
I have also looked at "Submit HTML form to PDF"
I have used fpdf several times to create php-based pdf documents. An example following:
require('fpdf.php');
$pdf = new FPDF();
$pdf->AddFont('georgia', '', 'georgia.php');
$pdf->AddFont('georgia', 'B', 'georgiab.php');
$pdf->AddFont('georgia', 'I', 'georgiai.php');
# Add UTF-8 support (only add a Unicode font)
$pdf->AddFont('freesans', '', 'freesans.php', true);
$pdf->SetFont('freesans', '', 12);
$pdf->SetTitle('My title');
$pdf->SetAuthor('My author');
$pdf->SetDisplayMode('fullpage', 'single');
$pdf->SetLeftMargin(20);
$pdf->SetRightMargin(20);
$pdf->AddPage();
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
You can learn very fast with these tutorials from the website itself.
EDIT: Example to save form data: (yes, is very easy...)
require('fpdf.php');
$pdf = new FPDF();
$pdf->AddPage();
foreach ($_POST as $key =>$data)
{
$pdf->Write(5, "$key: $data"); //write
$pdf->Ln(10); // new line
}
$pdf->Output($path_to_file . 'file.txt','F'); // save to file
Look at these pages created with fpdf, really!
http://www.fpdf.org/
That would be the library to do it. I used it here to add images to a form and submit it to create a PDF with those images: http://productionlocations.com/locations
The actual code to do it is pretty complex.
I have found PrinceXML very easy to use. It takes your HTML/XML, applies CSS, and converts it into a PDF. The PHP extensions work very well. Unfortunately, it's not free.
One way you can consider is using an online API that converts any HTML to PDF. You can send them a generated HTML (easier to produce) that will contains your user's submitted data, and receive back a high fidelity PDF.
There are quite a few services available on the market. I like to mention PDFShift because it offers a package in PHP that simplifies the work for you.
Once you've installed it (using Composer, or downloaded it directly, depending on your choices) you can quickly convert an HTML document like this:
require_once('vendor/autoload.php');
use \PDFShift\PDFShift;
PDFShift::setApiKey('{your api key}');
PDFShift::convertTo('https://link/to/your/html', null, 'invoice.pdf');
And that's it. There are quite a few features you can implement (accessing secured documents, adding a watermark, and more).
Hope that helps!

Dynamically insert content into pdf files with php

I have an ebook in word that I convert to PDF before distributing to my clients. I'd like to dynamically insert their email address into all links in the ebook to allow them access to the members-only content on my site, and I'd like to do this on the fly, as part of the book download process.
I've briefly looked at http://us.php.net/pdf and FPDF, but I was wondering what specific technique I'd use to insert this data.
I was thinking I'd insert an email token string where I want the email address to go, and then use some function to update those tokens in the PDF document.
Can anyone point me in the right direction? I have php experience, but not with editing / generating pdf documents from php.
EDIT: Yes, this commercial script http://www.setasign.de/products/pdf-php-solutions/setapdf-linkreplacer/ does exactly what I needed.
So far it's looking like this is my best bet:
http://www.setasign.de/products/pdf-php-solutions/setapdf-linkreplacer/
Trying an eval copy of it, will update post with results.
you can do this with FPDI extension for FPDF http://www.setasign.de/products/pdf-php-solutions/fpdi/
it enables fpdf to import existing pdf files, though I'm not sure how can one replace links.
I'd say your best shot would be to generate the whole thing in php, or just save it in html, replace links in html, then convert html to pdf.
Without using the Adobe LiveCycle Designer, the easiest way to generate a custom PDF is to use an FDF file. There are tons of ways to do this, one of which is to download binaries from Adobe and install them on your server. But none of that is really needed. All you need is a pdf with fillable forms and a simple script that makes and FDF file. The FDF simply holds the data that needs to be filled in and a pointer to the pdf file to be filled in. I use this for our timesheets at work. The data goes into a web form, but must come out static and ugly and using a paper from from 30 years ago. Here's what your fdf file will look like (both with code and raw):
$file = "http://www.example.com/blankpdfform.pdf";
$data = "%FDF-1.2\n%âãÏÓ\n1 0 obj\n<< \n/FDF << /Fields [ ";
foreach($datafields as $field => $val) {
$data.='<< /T ('.$field.') /V ('.trim($val).')>> ';
}
$data.="] \n/F (".$file.") /ID [ <".md5(time()).">\n] >>".
" \n>> \nendobj\ntrailer\n".
"<<\n/Root 1 0 R \n\n>>\n%%EOF\n";
The end result being:
%FDF-1.2\n%âãÏÓ\n1 0 obj\n<< \n/FDF << /Fields [<< /T (email) /V (email#address.com)>>
/F ("http://www.example.com/blankpdfform.pdf") /ID [ <"SomeUniqueID">
] >> \nendobj\ntrailer<<
/Root 1 0 R
>>
%%EOF
If you have the PDF template with the email token stored in a file on the webserver, you can do this fairly easily. First you need to read in the file using PHP. You can do this using the file_get_contents method. Then use str_replace to replace the email token with the actual email. Finally, serve the file with the correct content-type.
$pdf = file_get_contents( 'template.pdf' );
$pdf = str_replace( '__EMAIL__TEMPLATE__', $userEmail, $pdf );
header( 'Content-type: application/pdf' );
print $pdf;
Doc links:
http://ca2.php.net/manual/en/function.file-get-contents.php
http://ca2.php.net/manual/en/function.str-replace.php
(I haven't actually tried this and you may run into some issues since PDF is a binary format, but in theory it should work...)
