Requirements

The bundle requires PHP in version 8.1 or higher and Symfony in version 5, 6 or 7.

The html-to-pdf-library requires implementations of psr/http-message, psr/http-factory and psr/http-client.

How to install?

The bundle should be installed via composer: pmarien/html-to-pdf.

composer req pmarien/html-to-pdf

How to configure?

If you want to configure the bundle you should add the file config/packages/html_to_pdf.yaml.

Without api key configuration the bundle will act as anonymous client, which leads to a limit of 3 generated PDF files per day.

html_to_pdf:
  apiKey: 'YOUR_API_KEY'
  assetScheme: 'http' #optional to use a different asset location
  assetHost: 'example.com' #optional to use a different asset location

How to use internal assets?

If you want to use assets in your pdf, they have to be public accessible via http for the pdf generator. Sometimes you want to use the assets, but don't want to publish them. For those cases, this bundle comes with an AssetAccessController, which requires a hash for file protection.

The routing have to be enabled via config (config/routes/html_to_pdf.yaml):

HtmlToPdfBundle:
  resource: '@HtmlToPdfBundle/Resources/config/routes.xml'

Asset uris can be build manually (route name: html_to_pdf_get_file, required parameters: filename and hash) or via twig filter:

<img src="{{ '/assets/images/test.png'|pdfAsset }}" alt="Test">

If you build uris manually, the hash can be generated via PMA\HtmlToPdfBundle\Asset\AssetAccessorInterface::getHash (available as symfony service).

How to use?

If you want to generate pdf files directly from html, you should use PMA\HtmlToPdfBundle\Bridge\FoundationBridge as generator. It's available as service in the service container and may be autowired by symfony's dependency injection.

Controller (Inline PDF)

public function showAction(\PMA\HtmlToPdfBundle\Bridge\FoundationBridge $generator):\Symfony\Component\HttpFoundation\Response{
   return $generator->inlineResponse(
        'test.pdf',
        '<html><body><p>This is a test!</p></body></html>'
    );
}

Controller (Download PDF)

public function downloadAction(\PMA\HtmlToPdfBundle\Bridge\FoundationBridge $generator):\Symfony\Component\HttpFoundation\Response{
   return $generator->attachmentResponse(
        'test.pdf',
        '<html><body><p>This is a test!</p></body></html>'
    );
}

Service (Store PDF file)

public function storeFile(\PMA\HtmlToPdfBundle\Bridge\FoundationBridge $generator):void {
    $generator->createFile(
        '/your/project/file-storage/test.pdf',
        '<html><body><p>This is a test!</p></body></html>'
    );
}

Twig

If you want to generate pdf files from twig templates, you should use PMA\HtmlToPdfBundle\Bridge\TwigBridge as generator. It's available as service in the service container and may be autowired by symfony's dependency injection. It requires Twig to be installed in your project.

Controller (Inline PDF file)

public function showAction(\PMA\HtmlToPdfBundle\Bridge\TwigBridge $generator):\Symfony\Component\HttpFoundation\Response{
   return $generator->inlineResponse(
        'test.pdf',
         'pdf-templates/test.pdf.twig',
        [
            'test'=>'Test'
        ]
    );
}

Controller (Download PDF file)

public function downloadAction(\PMA\HtmlToPdfBundle\Bridge\TwigBridge $generator):\Symfony\Component\HttpFoundation\Response{
   return $generator->attachmentResponse(
        'test.pdf',
         'pdf-templates/test.pdf.twig',
        [
            'test'=>'Test'
        ]
    );
}

Service (Store PDF file)

public function storeFile(\PMA\HtmlToPdfBundle\Bridge\TwigBridge $generator):void {
    $generator->createFile(
        '/your/project/file-storage/test.pdf',
        'pdf-templates/test.pdf.twig',
        [
            'test'=>'Test'
        ]
    );
}
