Is it possible to feed TCPDF or FPDI PDFs as a string? I have an incoming array of PDFs as strings, and I can't write to disk. I wasn't able to find anything in the documentation about this.
If not, is there an efficient way to store/read these PDFs from memory or as objects? as to feed them to FPDI?
If you look at the setSourceFile method documentation, you will see that you can also pass a resource or a StreamReader. What is very interesting with the StreamReader is that it also shares a createByString method. So you can use it like this:
use setasign\Fpdi\PdfParser\StreamReader;
//...
$myData = ... ;
$stream = StreamReader::createByString($myData);
$pdf->setSourceFile($stream);
//...
This will avoid any code duplication... hope this helps someone in the future...
FPDI does not accept strings, but TCPDI, which I just released, has a setSourceData() method in addition to FDPI's setSourceFile(), as I happened to have the exact same requirement. TCPDI has its own parser (tcpdi_parser, based on TCPDF's parser) which supports PDFs above 1.4 without requiring the commercial addon for FPDI - which may also be of benefit when working with existing PDFs.
you can used stream wraper ,..
you can write wraper.php from class link above
header('Content-Type: text/html; charset=utf-8');
require_once('tcpdf/tcpdf.php');
require_once('fpdi/fpdi.php');
require_once('wraper.php');
// Creating new page with PDF as a background
$pdf = new FPDI();
$varInAnyScope = file_get_contents('proposal0.pdf');
$pdf->setSourceFile(VarStream::createReference($varInAnyScope));
$tplIdx = $pdf->importPage(1);
$pdf->AddPage();
$pdf->useTemplate($tplIdx, 0, 0, 0, 0, true);
$pdf->Write(0, "Stack overflow");
ob_clean();
$pdf->Output('WorksheetTest.pdf', 'I');

I am using FPDF to generate PDF contracts, however people in office often forgets to print ToS file with them and they want me to add ToS into every contract, but when I try to use both FPDF and FPDI it shows me err 500, I've never worked with those two so I am not sure if I can use it that way.
Thanks in advance, Lucas.
EDIT:
<?
require_once('_inc/fpdf.php');
require_once('_inc/fpdi/fpdi.php');
$doc = new FPDF();
$tos = new FPDI();
$doc->whtml("blahblah");
$tos->AddPage();
$tos->setSourceFile('ToS.pdf');
$tplIdx = $pdf->importPage(1);
$tos->useTemplate($tplIdx);
$tos->Output();
$doc->Output();
I'm trying to build an header generator for pdf worksheets.
My choice of technologies were:
FPDF and FPDI
Now, I'm transistioning to TCPDF and FPDI, because the powers that be have decided we need water marks (transparencies).
According to the FPDI website, switching is as easy as changing all your require/include statements to say tcpdf.php instead of fpdf.php but in my code below:
//... Code to generate appropriate Graph ...
PDFGenHelper::saveIMG($graph,$imgfilepath);
$filename = "template.pdf";
$pdf = new FPDI();
$pdf->AddPage();
$pdf->setSourceFile($filename);
$tplIdx = $pdf->importPage(1);
$pdf->useTemplate($tplIdx);
$pdf->Image($imgfilepath, 168, 13, 35, 65);
$pdf->Write(5, "This is just a simple text"); //This line
$pdf->Output($dircache.$userID.'_'.$excerciseID.'_package.pdf', 'F');
Seems to generate an error that says:
Warning: Division by zero in Appropriate directory stuff here/lib/fpdf/fpdf.php on line 819
I've removed all the references to fpdf in my code but it seems to still be coming up with that.
Also, when I try to print to the PDF using the inherited methods from FPDF:
$pdf->SetFont('Arial','B',25);
$pdf->Cell(40,10,'Hello World!');
This will generate text. In addition the FPDI website says FPDI has a Dependency on FPDF_TPL file which looking into the file tells me it extends FPDF.
So to my question: How do you configure FPDI to work with TCPDF instead of FPDF?
If the error is rised in lib/fpdf/fpdf.php then you still have required fpdf.php before TCPDF.
Also: If it's just the transparency you're missing, just use AlphaPDF from the script section.
I have a doubt about using TCPDF and FPDI together.
I am working on a project where I need to modify existing PDF file and generate new PDF, actually existing PDF are Greeting card template and I have to print certain data at certain pages (such as Image on first page, message on 3rd page, artwork on 4th page) to generate final PDF.
I googled and found with TCPDF, it is not possible to manipulate existing PDF, they suggested using FPDI for opening and manipulating existing PDF.
That's where i am stuck. I need TCPDF (it methods to print images, transparent images, utf text, embed font etc) to do what I want to do, but, I need FPDI to start with. :(.
Please help me: is it possible to use both FPDI and TCPDF together? so that I can use features offered by both APIs ?
Thanks in advance...

"As of version 1.2.1 FPDI can be used with TCPDF - a derivate of FPDF."
libraries_load('tcpdf');
libraries_load('fpdi');
$pdf = new FPDI();
$pdf->setSourceFile("%local_file_path%");
$tplIdx = $pdf->importPage(1);
$pdf->AddPage('L', array(3.5, 2), FALSE);
$pdf->useTemplate($tplIdx, 0, 0, 3.5, 2, false);
I was using Drupal at the time so I used libraries_load but require_once should work.
I have several PDF templates that I would like to load and modify and output using tcpdf.
Is it possible to load an existing PDF and use it as a starting point in tcpdf?
You want to use FPDI.
There's some example code here.
I have tried the free version of FPDI but does not support PDF version 1.5 or higher.
If someone else is looking for a free solution I have used TCPDI. You can find it on github https://github.com/pauln/tcpdi
If you are using composer, you can find some fork for composer too. Just search tcpdi on github.
Once you add it to your project, the code is quite simple. It is an extension of TCPDF so all your previous code keep working
This is a snippet from my code. I used it to save a copy of the privacy policy (a static pdf) with the user name and agreement date on each page footer.
// Create new PDF document
$pdf = new TCPDI(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
...
// Add the pages from the source file.
$pagecount = $pdf->setSourceFile($policyPdfPath);
for ($i = 1; $i <= $pagecount; $i++) {
$tplidx = $pdf->importPage($i);
$pdf->AddPage();
$pdf->useTemplate($tplidx);
// Add agreement text in document footer
$pdf->SetXY(15,282);
$pdf->Cell(180, 5, "Documento approvato da {$fullName} il {$date}", 0, 0, 'C');
}
// Send PDF on output
$pdf->Output(FOLDER_PATH . DIRECTORY_SEPARATOR . "{$userId}.pdf", 'F');
For anyone else finding this, it does appear a PARSER and import class were built for TCPDF (https://tcpdf.org/docs/srcdoc/TCPDF/source-class-TCPDF_IMPORT/#50-100) but as of 2018 was still under development.
Its also worth noting that the solutions above do not allow the contents of the PDF pages to be edited. In other words you import the page as a whole, you cannot edit text content or images.
You can use fpdf with fpdi. You can’t modify directly a template, but you can add a text cell with a white background to cache the old content (note that the old content can be read by using some tools). Then save your new pdf. This tools are relatively easy to use. To resolve the fact that fpdi not read 1.5 pdf version in the free version, you can convert 1.5 version in 1.4 version by using ghost script with the exec command. I use this and work fine.
Background info:
I got a project to produce a customised PDF on the fly from a given PDF file using PHP. All I need it to do is to replace strings, e.g. search in "template.pdf" for "{Address}", replace with "Street Name".
I've seen links to fpdf/pdfi/dompdf etc., but can't find any useful example code that I could use :s.
Any help / pointers would be greatly appreciated.
fpdf is fantastic, you need to use somthing else to import an exisitng PDF though, See below.
http://www.setasign.de/products/pdf-php-solutions/fpdi/
require_once('fpdf.php');
require_once('fpdi.php');
$pdf =& new FPDI();
$pagecount = $pdf->setSourceFile('TestDoc.pdf');
$tplidx = $pdf->importPage(1, '/MediaBox');
$pdf->addPage();
$pdf->useTemplate($tplidx, 10, 10, 90);
$pdf->Output('newpdf.pdf', 'D');
decided to generate html web page (PHP) then use wkhtmltopdf
(http://code.google.com/p/wkhtmltopdf)
to produce the pdf bit of a work around but less hastle
PDFlib (with the additional PDI) from pdflib.com should be able to do this for you. Admittedly it is pretty pricey, so there may be other options, too :)
