README
This is a basic wrapper around Snappy implemented as Yii application component. Snappy is a PHP library that uses wkhtmltopdf and wkhtmltoimage to render HTML into PDF and various image formats.
Installation
Installation using Composer should be straightforward
% composer require dmitrivereshchagin/yii-snappy
To register components in your application add something like the
following in configuration components
section:
'pdf' => array( 'class' => 'dmitrivereshchagin\\yii\\snappy\\PdfComponent', 'binary' => '/usr/local/bin/wkhtmltopdf', 'options' => array('orientation' => 'landscape'), 'tempdir' => basename(__DIR__).'/runtime/pdf', ), 'image' => array( 'class' => 'dmitrivereshchagin\\yii\\snappy\\ImageComponent', 'binary' => '/usr/local/bin/wkhtmltoimage', 'tempdir' => basename(__DIR__).'/runtime/image', ),
Specifying paths to binaries is mandatory. Optionally you can configure
default command line arguments that can be overridden or adjusted later.
It is also possible to set temporary directory for both components using
snappyTempdir
application parameter.
Usage
Use Yii::app()->pdf
and Yii::app()->image
to generate PDF documents
and images respectively. These components provide access to methods
declared by \Knp\Snappy\GeneratorInterface
.
Here are some examples.
Generate image from an URL
Yii::app()->image->generate('http://example.com', '/path/to/image.jpg');
Generate PDF document from an URL
Yii::app()->pdf->generate('http://example.com', '/path/to/document.pdf');
Generate PDF document from multiple URLs
Yii::app()->pdf->generate( array('http://example.com', 'http://example.org'), '/path/to/document.pdf' );
Generate PDF document from a view
Yii::app()->pdf->generateFromHtml( $this->render('view', array('name' => $value), $return = true), '/path/to/document.pdf' );
Generate PDF document as response from controller
$html = $this->render('view', array('name' => $value), $return = true); Yii::app()->request->sendFile( 'document.pdf', Yii::app()->pdf->getOutputFromHtml($html) );
Generate PDF document with relative URLs inside
$url = Yii::app()->createAbsoluteUrl('controller/action'); Yii::app()->request->sendFile( 'document.pdf', Yii::app()->pdf->getOutput($url) );
