Hey guys,

i want to use footer in my dynamic generated pdf files with the footer-html option but it doesn't work.
Here is my code:

$footer = url('documents/pdf/footer'); // generate footer url (html output)
PDF::loadView('documents.pdf.offer', $data)->setOption('footer-html', $footer);

If i want to view my pdf i only get an error: Error on load pdf file. :(

When not set the option:

setOption('footer-html', $footer);

the pdf generations works fine.

When I generated pdf I have always mobile version. Where can I set screen size? When I checked in javascript my screen and window size for pdf I have 640px for screen and 0px for windows width. I would like to have normal version (no mobile).

I use foundation for responsive template.

I'm using this to render an HTML file to a pdf. I've built it on a test server and it all works perfectly but when I move it to the live server none of the images show at all. I've tried using png and jpg images as well as relative, absolute and full paths but nothing I do seems to work.

When I go to /home/ubuntu/wkhtmltox/bin/wkhtmltopdf http://www.google.com test.pdf I get this:

Loading pages (1/6)
QSslSocket: cannot resolve SSLv2_client_method ] 10%
QSslSocket: cannot resolve SSLv2_server_method
Counting pages (2/6)

Resolving links (4/6)

Loading headers and footers (5/6)

Printing pages (6/6)
Done

Then it saves a pdf of the homepage (containing the images too) to the server.

I've tried using:

http://{{ domain }}/pdf/images/background_logo.png
http://subdomain.livesite.com/pdf/images/background_logo.png

both of which work on the test server, but not the live one.

The code used to generate the pdf is:

public function generatePdf($app)
{
$products = $this->getRecurringOrderProducts();
if (count($products) > 0) {
$filename = $this->getPdfFilename($app);
if (!file_exists($filename)) {
// Generate HTML
$html = $app['twig']->render('order/pdf.twig', array(
'entry' => $this,
'products' => $products,
'expiry_date' => $this->getExpiryDate(), // Add this line
'content_height' => intval( (8_100_count($products))/95 )+1,
'domain' => $app['config']['domain'],
));
// Generate PDF
$snappy = new Pdf($app['wkhtmltox_bin']);
$snappy->setOption('orientation', 'landscape');
$snappy->generateFromHtml(utf8_decode($html), $filename);
}
}
}

I've spent weeks getting this to work without any luck, if anybody has any suggestions I'm be extremely grateful.

Thank you

I am using the snappy bundle with Symfony2 version 2.1.*

When I call $this->get('knp_snappy.pdf')->getOutputFromHtml($html);

I get this error

"The process stopped because of a "0" signal"

I get the same error if I use

$snappy = new Pdf('/usr/local/bin/wkhtmltopdf');
$snappy->setOption('header-html', false);
$snappy->setOption('footer-html', false);
$snappy->setOption('no-background', true);
$output = $snappy->getOutput('http://www.google.com');

Is the snappy bundle compatible with 2.1.* ?

Thanks

If header-html or footer-html is null, then the tmp files are not created but snappy still tries to unlink them.
#121

Origin of the problem:
7bbb268
The same logic isn't used when deciding to generate as deciding to unlink.

I'm running this class using the code on your site, but it's returning a zero byte empty PDF file.

require_once 'libraries/autoload.php';
use Knp\Snappy\Pdf;

$snappy = new Pdf('/usr/bin/wkhtmltopdf');

header('Content-Type: application/pdf');
header('Content-Disposition: attachment; filename="file.pdf"');
$snappy->generateFromHtml($out1, '/tmp/'.session_id().'.pdf');

I've checked the tmp file and it's there but NOT empty. What gives and why is the downloaded version empty??

Got an Uncaught PHP Exception RuntimeException: "The exit status code '1' says something went wrong when Warning: Failed loading page even with the --load-error-handling ignore. The pdf is correctly generated from the command, but cannot be displayed immediatly after generation because of this RuntimeException. (This is provocated when any asset cannot be loaded (404 for instance)).

This is due to the checkProcessStatus method from Knp\Snappy\AbstractGenerator class, which is only checking if status code === 0.

Catching the Exception isn't enough to get output, since tmp file content isn't retrieved before. Cannot we let the choice to retieve or not the errors and display the pdf by :

• Catching excption internally (generate method)
• Populating an errors array
• Giving the possibility to add the errors array to getOutput($input, array $options = array()) method as reference

So it will result to :

public function getOutput($input, array $options = array(), array &$errors = array())
 {
       $filename = $this->createTemporaryFile(null, $this->getDefaultExtension());

       try {
            $this->generate($input, $filename, $options);
        } catch(RuntimeExcpetion){
            //Populates $errors
        }

        $result = $this->getFileContents($filename);

        $this->unlink($filename);

        return $result;
 }

Idem for LoggableGenerator from KNPSanppyBundle.

Hi there,

can someone explain me how to deal with toc (table of contents) and cover objects ? I believe buildCommand does not support them properly as it seems they are treated like regular options (adding "--" to them) but they are not.

This is almost similar to request #29 because cover and toc are objects just like pages, so if we were able to add several pages to the command, there wouldn't be much work to add support for toc and cover objects either.

The exit status code '1' says something went wrong:
stderr: "Unknown long argument --cover

[...]

(page)? <input url/file name> [PAGE OPTION]...
Options for the page object can be placed in the global options and the page
options areas. The applicable options can be found in the Page Options and
Headers And Footer Options sections.

A cover objects puts the content of a singe webpage into the output document,
the page does not appear in the table of content, and does not have headers
and footers.

cover <input url/file name> [PAGE OPTION]...
All options that can be specified for a page object can also be specified for
a cover.

A table of content object inserts a table of content into the output document.

toc [TOC OPTION]...
All options that can be specified for a page object can also be specified for
a toc, further more the options from the TOC Options section can also be
applied. The table of content is generated via XSLT which means that it can be
styled to look however you want it to look. To get an aide of how to do this
you can dump the default xslt document by supplying the
--dump-default-toc-xsl, and the outline it works on by supplying
--dump-outline, see the Outline Options section.

Thanks

Please add support or a documentation how to install snappy with the new composer.phar install behaviour like in Symfony 2.1.*

Passing large html string to $options['header-html'] & $options['footer-html'] cause handleOptions() to check if those options are uris or files before fallback on creatingTemporaryFile().

This call AbstractGenerator:isFile(), and so php's is_file() with strings which can be too large for many filesystem defaults. Response is false as expected but emit a warning.

We can check for string length in Pdf.php, or in AbstractGenerator.php, or simply ignore the warning.

I've load the current wkhtmltopdf-0.9.9-OS-X.i368 from the developer page (http://code.google.com/p/wkhtmltopdf/) and install SnappyBundle as described at install guide.
Everything looks fine but when I try to generate an pdf throw the snappy bundle I got following error:

The exit status code '5' says something went wrong:
stderr: "dyld: Symbol not found: __cg_jpeg_resync_to_restart

´´´´

When I run the some command from the terminal: command: /usr/bin/wkhtmltopdf 'http://www.google.at' '/Applications/MAMP/htdocs/cosamui/web/data/test.pdf' it works as expected.

What can I do to solve this issue? Anyone other the same problem?

I get the PDF downloaded instantly, and it's not empty either (arround 3KB, single page) but upon opening chrome says "failed to load" and adobe reader says the document is damaged and cannot be opened.
I also noticed that it only gives me the download when I have PHP display errors ON, with them off for some reason the page (The file below) is not available and cannot load but other parts of my application still work witch means my PHP server works (I'm using wamp).
Here's the code:

require_once '/vendor/knplabs/knp-snappy/src/autoload.php';

use Knp\Snappy\Pdf;

$snappy = new Pdf('/vendor/h4cc/wkhtmltopdf-amd64/bin/wkhtmltopdf-amd64');

header('Content-Type: application/pdf');
header('Content-Disposition: attachment; filename="file.pdf"');
echo $snappy->getOutput('http://localhost/Ponudomat%20wSnappy/printRdy.php');

There is an option in wkhtmltopdf that allows converting of more than one URL at a time. Is there a way to do this with snappy? I did not see it in the options class.

Thanks!

What do you think of supporting other pdf generators than wkhtmltopdf ?

I'm thinking about prince xml for example : http://www.princexml.com/

I can manage this if you give me the entry points for a multiple pdf generator backends code modifications.

Using Laravel 4 with wkhtmltopdf installed via Homebrew.

Is it possible to generate the pdf and store it without doing anything further?

This would be really useful where other non-snappy processing needs to take place. E.g Creating a pdf file, then creating some other project files. Zipping them up and then I can output the zip file myself for download.

I have gone through the previous posts for the same topic (Issue #20) and other posts providing solutions for the problem. But nothing seems to work for me. I keep getting :

The file 'bill-123.pdf' was not created (command: /usr/local/bin/wkhtmltopdf --lowquality --no-background '/var/folders/p6/p6c0IfxzHbCVZZR6XsXBB++++TI/-Tmp-/knp_snappy501019a8e558f6.63368539.html' 'bill-123.pdf').

I am using MAMP and Symfony2.1. Although I am able to generate the pdf using the same command in the terminal. Please let me know if I am missing something here. Anticipating your response. Thank you.

Not rendering text when i try to generate pdf

Based on the example in the readme, when I use generateFromHtml I get the following.

If I try to have it send the pdf for download then the pdf is corrupted and wont open.

I have a weird error with background images. In my system, I loop through a number of pages each containing some HTML to output. This is the master page:

<html>
    <head>
        <meta charset="UTF-8">
        <link rel="stylesheet" type="text/css" href="/home/vagrant/code/acme/app/storage/bootstrap.css">
        <style type="text/css">
            div.page:not(:first-child) {
                page-break-before: always;
            }
            div.page {
                background-image: url('/home/vagrant/code/acme/app/storage/bg.jpg');
                background-size: 100% 100%;
                height: 100%;
                width: 100%;
                color: white;
            }
        </style>
    </head>
    <body>
        @foreach($pages as $page)
            {{ $page }}
        @endforeach
    </body>
</html>

However, the output is not as expected: when I have 5 pages in the $pages array, I get 16 pages in the PDF. The first two pages are rendered correctly, but the third spans 2 pages, the fourth spans 4 pages and the fifth spans 8 pages. The content of each $page is just <div class="page">foo</div>.

How can I use background images with snappy?

knp_snappy:
    pdf:
        enabled:    true
        binary:     /usr/local/bin/wkhtmltopdf-amd64
        options:    
          redirect-delay: 1000

throws an invalid option exception

Removing lines 70-72 from Knp\Snappy\AbstractGenerator.php solves the problem but I see that this provides some validation.

How do I set the allowed options using the snappy-bundle?

Fatal error: Class 'Knp\Snappy\Pdf' not found in /Users/joseym/Sites/tests/pdf/index.php on line 6

$snappy->setOption('user-style-sheet','PDFCss.css');
I tried to include the user-defined css to the pdf generated but Css Failed to load.

How to I include external css file????

We are using wkhtmltopdf to export html to pdf. It breaks the HTML

Can anybody confirm how we can insert page break at the time of conversion from html to pdf with wkhtmltopdf?

When I print with wkhtml from the command line, no problem.
When I print with snappy, special characters are not displayed properly.
' becomes ’
é becomes é
and so on.

Maybe its an option that I have to set. Or a php extension that I am missing. Does it work with you to print special characters in snappy?

thanks.

Hi!

First off all, congratulations for your "library", is great!! ;-D

I have been studying the params relationated with "wkhtmltoImage", and one of the params is --run-script, but you only can add js code directly.

Is there any posibility (or do you know) of adding a URL of a 'file.js' in order to create functions or more code in a separated file (like the '-user-style-sheet' param)?

At the moment, I have checked that you can only add js code in one line, and it's a problem if you want to add more code :-(

• I'm using the libwkhtmltox-0.11.0_rc1.zip (Win) and I'll install it in Linux too.

Thank you very much in advance!

Hi,

When i use wkhtmltojpg from the command line it work but when i use it from my application it doesn't. That why i think it come from KnpSnappy.

The error:

The exit status code '1' says something went wrong:
stderr: "wkhtmltopdf: cannot connect to X server

stdout: ""

wkhtmltopdf --version

Any ideas ?

Hello guys

I've been trying to put Snappy to work on Windows (IIS) with no success.

What I've done:

• Installed wkhtmltopdf-0.9.9-installer.exe from http://code.google.com/p/wkhtmltopdf/downloads/list
• Downloaded snappy and copied the src folder to web folder.

My code:

Result:
Shows one pdf file to open or save, but it's corrupted.

P.S: In the command line wkhtmltopdf works well.

I'm doing something wrong?

Thanks in advance,
Pete

Hey there,

I am able to include the autoloader (require_once('snappy/src/autoload.php');) but when I specify the namespace (use Knp\Snappy\Pdf;) I get a fatal error (white screen) but nothing actually comes back in the error log.

Has anyone had any luck using snappy from within the Zend (1.12) framework?

I try to use the toc parameter without success.
The generated command contains --toc instead of toc.

Do you think it can be done easily ?

Thanks

Getting an error while trying to execute this code:

On Windows, I'm using symfony/symfony@fae4523, KnpLabs/KnpSnappyBundle@b8be046, and wkhtmltopdf 0.11.0_rc1. When doing a conversion of a document and adding a footer with the footer-html option, the process is hanging until max_execution_time is reached. After that, the wkhtmltopdf process gets killed and the perfectly rendered PDF file is in the system's temp folder. So the conversion is already done at that moment.

The script is aborted with a timeout referred to

I took another approach by removing the code in

$process = new \Symfony\Component\Process\Process($command);
$process->run();
return array(
    $process->getExitCode(),
    $process->getOutput(),
    $process->getErrorOutput(),
);

to use Symfony's Process class and take advantage of symfony/symfony#4069. But even in this case the process is hanging and the script is aborted referring to https://github.com/symfony/symfony/blob/fae4523f3baf1595b1c632e4953f667e93149f9b/src/Symfony/Component/Process/Process.php#L360.

Without the footer-html option, everything runs fine.

How are values for options

--cookie <name> <value>
--custom-header <name> <value>
--post <name> <value>
--post-file <name> <path>
--replace <name> <value>

meant to be passed to the generator? I couldn't find a proper way.

Could we have a new release tag to include the latest toc & cover option changes?
Thanks

How do you setup a Header and Footer HTML with this class? I can't find the documentation anywhere :(

Sorry to bug you guys. I wish I could figure this out on my own but I'm utterly stuck at this point. I'm running a Mac with MAMP and can run wkhtmltopdf from the command line just fine. In fact I can run the exact command that Snappy is attempting to run (copied and pasted from $command) just fine and get the PDF I'm looking for. I've run chmod a+x and chmod 777 on the executable. I've changed the owner of the executable to the apache account. But when Snappy tries to run the command it fails with exit code 5 and nothing in stderr or stdout. Any ideas?

Snappy create a lot of temporary files but never delete them.
On a production server, this could become problematic since the size of the temp dir could increase very fast.

When the input or the output are stored in a temporary file, these files should be deleted just before the result is returned.

Hi,

I just start to do my own handler of wkhtml2pdf, when someone tell me about this project.

I include wkhtp2pdf as composer require, and as composer repositories as you can see here https://github.com/desarrolla2/php-wkhtmltopdf/blob/master/composer.json

And then i was thinking in initialize the environment as you can see in this constructor method https://github.com/desarrolla2/php-wkhtmltopdf/blob/master/src/Desarrolla2/WKHtml2Pdf/Handler.php

What about if i send PR for include this in this package?

Regards

I have file.html with content below

<div class="Logo">
    <img src="/assets/ui/logo-commoncore.svg">
</div>

I use code below to render pdf

$fileContent = file_get_content('file.html');
$snappy = new Pdf('wkhtmltopdf');
header('Content-Type: application/pdf');
return $snappy->getOutputFromHtml($fileContent );

The image assets/ui/logo-commoncore.svg is not apears

but if i add absolute url it will fix the problem

<div class="Logo">
    <img src="http://mysite.com/assets/ui/logo-commoncore.svg">
</div>

How i can avoid to add sile_url to any image tag in page?
What is the native way to set path to images in php code ?

I am trying to use

$pageUrl = $this->generateUrl('arout', array(), true); 

return new Response(
    $this->get('knp_snappy.pdf')->getOutput($pageUrl),
    200,
    array(
        'Content-Type'          => 'application/pdf',
        'Content-Disposition'   => 'attachment; filename="file.pdf"'
    )
);

It generating the login page of my web application. I am sure 'arout' do not rout to login page.

I installed and tested snappy library for pdf generating.
Everything works fine.
But is there a way to have multiple html url´s or html files as input.

When i try this:
$snappy->generate('http://bag2go.de http://bag2go.de/taschen.php http://bag2go.de/material.php', 'tmp/test-5.pdf');

i get this:
Error: Failed loading page http://bag2go.de/taschen.php http://bag2go.de/material.php

When i try the same on console bash it works:

wkhtmltopdf-i386 http://bag2go.de http://bag2go.de/taschen.php http://bag2go.de/material.php /var/www/upload/test.pdf

Any hints?

I am trying to generate a PDF from twig and I am using the following code

$myTwig= "ABCReportBundle:TestEH:showAsTable.html.twig";
$html1 = $this -> renderView($myTwig, array('portal' => $portal, 'reports' => $reports));
return new Response($this -> get('knp_snappy.pdf') -> getOutputFromHtml($html1), 200, 
                            array('Content-Type' => 'application/pdf', 
                            'Content-Disposition' => 'attachment; 
                            filename="ReportWithChart.pdf"'));

My intention is to produce PDF from the content of the twig file only. But it generating the the whole template. Its not showing any image and CSS is missing.

As nobody seemed to respond to my comment, Ill create it here.
We're passing the following as the path with the symfony2 snappy bundle:

  wkhtmltopdf_bin: 'export DISPLAY=:0;/bin/wkhtmltopdf'

The commit #29866d9 breaks that by enclosing the path in quotes.

I get this error when below code runs

The file '/var/tmp/knp_snappy51db03691aa540.12804579.pdf' was not created (command: [site-dir]/vendor/google/wkhtmltopdf-i386/wkhtmltopdf-i386 --lowquality 'http://www.github.com' '/var/tmp/knp_snappy51db03691aa540.12804579.pdf').

$snappy = Helper::snappyPdf(); #this just returns snappy pdf object
echo $snappy->getOutput('http://www.github.com');

So I tried running wkhtmltopdf as sudo from command line (below code) and got a cannot execute binary error

[site path]/vendor/google/wkhtmltopdf-i386/wkhtmltopdf-i386 --lowquality 'http://www.github.com' '/var/tmp/knp_snappy51db03691aa540.12804579.pdf'

FYI I tried both 32 and 64 bit binaries and I installed wkhtmltopdf using composer

When running HTML to image converter it hangs forever. The exec runs fine, and outputs the file and quits, but Snappy just hangs.

Installing Symfony Process fixes this, but then causes an error:

RuntimeException 0 The exit status code '3' says something went wrong:
