PHPTK has a option that allows library devs to set a background for the pdf that is generated and here is the link - https://github.com/mikehaertl/php-pdftk#add-background-pdf
But in short it tells to add -
$pdf->background('/path/back.pdf')
But when I use this in my code it doesn't work I mean the back.pdf is not a background inside my generated pdf.
public function generate($pdfdata)
{
$pdfname = 'pdf_'.rand(2000, 1200000).'.pdf';
$pdf = new Pdf("./rawpdf/test.pdf");
$pdf->fillForm($pdfdata)
->flatten()
->needAppearances()
->saveAs("./generated/".$pdfname);
return $pdfname;
}
In my thought process I think If i use the background then it should be behind the text or can be said over the generated pdf but those things don't happen by the way if i am using this not correctly please correct me I new to this library.

I am working on a Symfony 1.4 project. I need to make a PDF download link for a (yet to be) generated voucher and I have to say, I am a bit confused. I already have the HTML/CSS for the voucher, I created the download button in the right view, but I don't know where to go from there.
Use Mpdf to create the pdf file

+1 with wkhtmltopdf
I'd even recommand the snappy library.
If you use composer, you can even get the wkhtmltopdf binaries automatically
Having used wkhtmltopdf for a while I've moved off it as 1) it has some serious bugs and 2) ongoing development has slowed down. I moved over to PhantomJS which is proving to be much better in terms of functionality and effectiveness.
Once you've got something like wkhtmltopdf or PhantomJS on your machine you need to generate the HTML page and pass that along to it. I'll give you an example assuming you use PhantomJS.
Initially set what every request parameters you need to for the template.
$this->getRequest->setParamater([some parameter],[some value]);
Then call the function getPresentation() to generate the HTML from a template. This will return the resulting HTML for a specific module and action.
$html = sfContext::getInstance()->getController()->getPresentation([module],[action]);
You'll need to replace the relative CSS paths with a absolute CSS path in the HTML file. For example by running preg_replace.
$html_replaced = preg_replace('/"\/css/','"'.sfConfig('sf_web_dir').'/css',$html);
Now write the HTML page to file and convert to a PDF.
$fp = fopen('export.html','w+');
fwrite($fp,$html_replaced);
fclose($fp)
exec('/path/to/phantomjs/bin/phantomjs /path/to/phantomjs/examples/rasterize.js /path/to/export.html /path/to/export.pdf "A3");
Now send the PDF to the user:
$this->getResponse()->clearHttpHeaders();
$this->getResponse()->setHttpHeader('Content-Description','File Transfer');
$this->getResponse()->setHttpHeader('Cache-Control','public, must-revalidate, max-age=0');
$this->getResponse()->setHttpHeader('Pragma: public',true);
$this->getResponse()->setHttpHeader('Content-Transfer-Encoding','binary');
$this->getResponse()->setHttpHeader('Content-length',filesize('/path/to/export.pdf'));
$this->getResponse()->setContentType('application/pdf');
$this->getResponse()->setHttpHeader('Content-Disposition','attachment; filename=export.pdf');
$this->getResponse()->setContent(readfile('/path/to/export.pdf'));
$this->getResponse()->sendContent();
You do need to set the headers otherwise the browser does odd things. The filename for the generated HTML file and export should be unique to avoid the situation of two people generating PDF vouchers at the same time clashing. You can use something like sha1(time()) to add a randomised hash to a standard name e.g. 'export_'.sha1(time());
Use wkhtmltopdf, if possible. It is by far the best html2pdf converter a php coder can use.
And then do something like this (not tested, but should be pretty close):
public function executeGeneratePdf(sfWebRequest $request)
{
$this->getContext()->getResponse()->clearHttpHeaders();
$html = '*your html content*';
$pdf = new WKPDF();
$pdf->set_html($html);
$pdf->render();
$pdf->output(WKPDF::$PDF_EMBEDDED, 'whatever_name.pdf');
throw new sfStopException();
}

Does anyone know of a good method for editing PDFs in PHP? Preferably open-source/zero-license cost methods. :)
I am thinking along the lines of opening a PDF file, replacing text in the PDF and then writing out the modified version of the PDF?
On the front-end
If you are taking a 'fill in the blank' approach, you can precisely position text anywhere you want on the page. So it's relatively easy (if not a bit tedious) to add the missing text to the document. For example with Zend Framework:
<?php
require_once 'Zend/Pdf.php';
$pdf = Zend_Pdf::load('blank.pdf');
$page = $pdf->pages[0];
$font = Zend_Pdf_Font::fontWithName(Zend_Pdf_Font::FONT_HELVETICA);
$page->setFont($font, 12);
$page->drawText('Hello world!', 72, 720);
$pdf->save('zend.pdf');
If you're trying to replace inline content, such as a "[placeholder string]," it gets much more complicated. While it's technically possible to do, you're likely to mess up the layout of the page.
A PDF document is comprised of a set of primitive drawing operations: line here, image here, text chunk there, etc. It does not contain any information about the layout intent of those primitives.
There is a free and easy to use PDF class to create PDF documents. It's called FPDF. In combination with FPDI (http://www.setasign.de/products/pdf-php-solutions/fpdi) it is even possible to edit PDF documents.
The following code shows how to use FPDF and FPDI to fill an existing gift coupon with the user data.
require_once('fpdf.php');
require_once('fpdi.php');
$pdf = new FPDI();
$pdf->AddPage();
$pdf->setSourceFile('gift_coupon.pdf');
// import page 1
$tplIdx = $this->pdf->importPage(1);
//use the imported page and place it at point 0,0; calculate width and height
//automaticallay and ajust the page size to the size of the imported page
$this->pdf->useTemplate($tplIdx, 0, 0, 0, 0, true);
// now write some text above the imported page
$this->pdf->SetFont('Arial', '', '13');
$this->pdf->SetTextColor(0,0,0);
//set position in pdf document
$this->pdf->SetXY(20, 20);
//first parameter defines the line height
$this->pdf->Write(0, 'gift code');
//force the browser to download the output
$this->pdf->Output('gift_coupon_generated.pdf', 'D');
If you need really simple PDFs, then Zend or FPDF is fine. However I find them difficult and frustrating to work with. Also, because of the way the API works, there's no good way to separate content from presentation from business logic.
For that reason, I use dompdf, which automatically converts HTML and CSS to PDF documents. You can lay out a template just as you would for an HTML page and use standard HTML syntax. You can even include an external CSS file. The library isn't perfect and very complex markup or css sometimes gets mangled, but I haven't found anything else that works as well.
Don't know if this is an option, but it would work very similar to Zend's pdf library, but you don't need to load a bunch of extra code (the zend framework). It just extends FPDF.
http://www.setasign.de/products/pdf-php-solutions/fpdi/
Here you can basically do the same thing. Load the PDF, write over top of it, and then save to a new PDF. In FPDI you basically insert the PDF as an image so you can put whatever you want over it.
But again, this uses FPDF, so if you don't want to use that, then it won't work.
Zend Framework can load and edit existing PDF files. I think it supports revisions too.
I use it to create docs in a project, and it works great. Never edited one though.
Check out the doc here
The PDF/pdflib extension documentation in PHP is sparse (something that has been noted in bugs.php.net) - I reccommend you use the Zend library.
Tcpdf is also a good liabrary for generating pdf in php
http://www.tcpdf.org/
We use pdflib to create PDF files from our rails apps. It has bindings for PHP, and a ton of other languages.
We use the commmercial version, but they also have a free/open source version which has some limitations.
Unfortunately, this only allows creation of PDF's.
If you want to open and 'edit' existing files, pdflib do provide a product which does this this, but costs a LOT
<?php
//getting new instance
$pdfFile = new_pdf();
PDF_open_file($pdfFile, " ");
//document info
pdf_set_info($pdfFile, "Auther", "Ahmed Elbshry");
pdf_set_info($pdfFile, "Creator", "Ahmed Elbshry");
pdf_set_info($pdfFile, "Title", "PDFlib");
pdf_set_info($pdfFile, "Subject", "Using PDFlib");
//starting our page and define the width and highet of the document
pdf_begin_page($pdfFile, 595, 842);
//check if Arial font is found, or exit
if($font = PDF_findfont($pdfFile, "Arial", "winansi", 1)) {
PDF_setfont($pdfFile, $font, 12);
} else {
echo ("Font Not Found!");
PDF_end_page($pdfFile);
PDF_close($pdfFile);
PDF_delete($pdfFile);
exit();
}
//start writing from the point 50,780
PDF_show_xy($pdfFile, "This Text In Arial Font", 50, 780);
PDF_end_page($pdfFile);
PDF_close($pdfFile);
//store the pdf document in $pdf
$pdf = PDF_get_buffer($pdfFile);
//get the len to tell the browser about it
$pdflen = strlen($pdfFile);
//telling the browser about the pdf document
header("Content-type: application/pdf");
header("Content-length: $pdflen");
header("Content-Disposition: inline; filename=phpMade.pdf");
//output the document
print($pdf);
//delete the object
PDF_delete($pdfFile);
?>
I need to export html page to pdf file with everything that's written in it, after I press submit button. It will open new page, with info, and I need for script to automatically make .pdf file (already uploaded to webserver), and get the link from file. Could you give me some easy example (if available, without any plugins, or other features that I must download, I would prefer clean PHP).
Just try this
HTML to PDF with PHP
Using open-source HTML2FPDF project
This solution uses HTML2PDF project (sourceforge.net/projects/html2fpdf/). It simply gets a HTML text and generates a PDF file. This project is based upon FPDF script (www.fpdf.org), which is pure PHP, not using the PDFlib or other third party library. Download [HTML2PDF][1], add it to your projects and you can start coding.
Code example
require("html2fpdf.php");
$htmlFile = "your link";
$buffer = file_get_contents($htmlFile);
$pdf = new HTML2FPDF('P', 'mm', 'Letter');
$pdf->AddPage();
$pdf->WriteHTML($buffer);
$pdf->Output('test.pdf', 'F');
I have a website now and I want to create a button on it to convert this page to PDF.
Is there any code to make this happen? I cannot find it on the internet.
So I want to have a button and when I press on it it converts the page to a .PDF file.
I do not want to use a third party website to generate the PDF's. I want to use it for internal purposes to generate files with PHP. So I need the code what can make a PDF for each page.
I use wkhtmltopdf - works very well - http://code.google.com/p/wkhtmltopdf/ there is a PHP wrapper
Updated based on comments below on usage :
How to use the integration class:
require_once('wkhtmltopdf/wkhtmltopdf.php'); // Ensure this path is correct !
$html = file_get_contents("http://www.google.com");
$pdf = new WKPDF();
$pdf->set_html($html);
$pdf->render();
$pdf->output(WKPDF::$PDF_EMBEDDED,'sample.pdf');
Use FPDF. It's a well-respected PDF-generating library for PHP that is written in pure PHP (so installing it should be dead simple for you).
Try this:
http://www.macronimous.com/resources/Converting_HTML2PDF_using_PHP.asp
It will convert HTML to a PDF using FPDF and HTML2PDF class.
Also found this:
http://www.phpclasses.org/package/3168-PHP-Generate-PDF-documents-from-HTML-pages.html
I'm trying to user HTML2FPDF (http://html2fpdf.sourceforge.net/) to create a PDF of a page, but I can't seem to get it to work properly.
My page consists of jQuery to show a graph. I want the graph and other text on the page to be exported as a PDF.
http://portal.flyingstartlifestyle.360southclients.com/leanne/leanne.php <- the graph with the html2fpdf code at the bottom of the page.
HTML2FPDF code:
function createPDF() {
define('ABSPATH', dirname(__FILE__).'/');
require(ABSPATH.'classes/pdf/html2fpdf.php');
$pdf = new HTML2FPDF();
$pdf->AddPage();
$html = ob_get_contents();
//$html = htmlspecialchars($html);
if ($html) {
$fileName = "testing.pdf";
$pdf->WriteHTML($html);
$pdf->Output("pdfs/".$fileName);
echo "<p>PDF file is generated successfully! Click here to open it.</p>";
} else {
echo "<p>There has been an error in creating your PDF.</p>";
};
};
If I unhide the line "$html = htmlspecialchars($html);" it prints the pdf the text of the page, otherwise it creates an empty PDF. Any ideas how I can transfer my graph to a PDF?
Cheers
A few years back, I've been beating my head against the wall trying to convert HTML into PDF for days. What I wanted to do was really simple - make an invoice for customers into a PDF file. An image (logo) up on top, a few paragraphs, and a table with a list of charges.
The hole shaped like my head on the wall is still there. All of the free libraries that convert things to PDF - they all suck. I found one that sucks the least, it's DomPDF. At least that one ended up doing the job, after a week of suffering and debugging. It's not fast by any means, though (if you want to generate a complex PDF, you might want to do it off-thread).
My page consists of jQuery to show a graph. I want the graph and other text on the page to be exported as a PDF.
jQuery is interpreted by the browser and not by the server. When you send the HTML to be rendered into PDF, it will not run the Javascript. You'll need to find a way to actually generate the image some other way.
I guess I could see a situation where you could use ajax to make a remote call and send all of the html that the js sees.
The remote call then would write a file of that html. The remote call would send back a file name for the pdf to be generated.
Your js then could provide a link to the processing page of the html2pdf that references the file created from the remote call.
This would work, but it might be a bit much.
Regards.
