Snappy

Build Status Scrutinizer Code Quality StyleCI

Snappy is a PHP library allowing thumbnail, snapshot or PDF generation from a url or a html page. It uses the excellent webkit-based wkhtmltopdf and wkhtmltoimage available on OSX, linux, windows.

You will have to download wkhtmltopdf 0.12.x in order to use Snappy.

Please, check FAQ before opening a new issue. Snappy is a tiny wrapper around wkhtmltox, so lots of issues are already answered, resolved or wkhtmltox ones.

Build Status

Following integrations are available:

Current maintainer(s)

Installation using Composer

$ composer require knplabs/knp-snappy

Usage

Initialization

<?php

require __DIR__ . '/vendor/autoload.php';

use Knp\Snappy\Pdf;

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

// or you can do it in two steps
$snappy = new Pdf();
$snappy->setBinary('/usr/local/bin/wkhtmltopdf');

Display the pdf in the browser

$snappy = new Pdf('/usr/local/bin/wkhtmltopdf');
header('Content-Type: application/pdf');
header('Content-Disposition: attachment; filename="file.pdf"');
echo $snappy->getOutput('http://www.github.com');

Merge multiple urls into one pdf

$snappy = new Pdf('/usr/local/bin/wkhtmltopdf');
header('Content-Type: application/pdf');
header('Content-Disposition: attachment; filename="file.pdf"');
echo $snappy->getOutput(array('http://www.github.com','http://www.knplabs.com','http://www.php.net'));

Generate local pdf file

$snappy = new Pdf('/usr/local/bin/wkhtmltopdf');
$snappy->generateFromHtml('<h1>Bill</h1><p>You owe me money, dude.</p>', '/tmp/bill-123.pdf');

Pass options to snappy

// Type wkhtmltopdf -H to see the list of options
$snappy = new Pdf('/usr/local/bin/wkhtmltopdf');
$snappy->setOption('disable-javascript', true);
$snappy->setOption('no-background', true);
$snappy->setOption('allow', array('/path1', '/path2'));
$snappy->setOption('cookie', array('key' => 'value', 'key2' => 'value2'));
$snappy->setOption('post', array('key' => 'value'));
$snappy->setOption('cover', 'pathToCover.html');
// .. or pass a cover as html
$snappy->setOption('cover', '<h1>Bill cover</h1>');
$snappy->setOption('toc', true);
$snappy->setOption('cache-dir', '/path/to/cache/dir');

wkhtmltopdf binary as composer dependencies

If you want to download wkhtmltopdf and wkhtmltoimage with composer you add to composer.json:

$ composer require h4cc/wkhtmltopdf-i386 0.12.x
$ composer require h4cc/wkhtmltoimage-i386 0.12.x

or this if you are in 64 bit based system:

$ composer require h4cc/wkhtmltopdf-amd64 0.12.x
$ composer require h4cc/wkhtmltoimage-amd64 0.12.x

And then you can use it

<?php

use Knp\Snappy\Pdf;

$myProjectDirectory = '/path/to/my/project';

$snappy = new Pdf($myProjectDirectory . '/vendor/h4cc/wkhtmltopdf-i386/bin/wkhtmltopdf-i386');

// or

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

N.B. These static binaries are extracted from Debian7 packages, so it might not be compatible with non-debian based linux distros

Some use cases

If you want to generate table of contents and you want to use custom XSL stylesheet, do the following:

<?php
$snappy = new Pdf('/path/to/binary');

$snappy->setOption('toc', true);
$snappy->setOption('xsl-style-sheet', 'http://path/to/stylesheet.xsl') //or local file;

$snappy->generateFromHtml('<p>Some content</p>', 'test.pdf');

Bugs & Support

If you found a bug please fill a detailed issue with all the following points.
If you need some help, please at least provide a complete reproducer so we could help you based on facts rather than assumptions.

  • OS and its version
  • Wkhtmltopdf, its version and how you installed it
  • A complete reproducer with relevant php and html/css/js code

If your reproducer is big, please try to shrink it. It will help everyone to narrow the bug.
