SilverStripe\Core\Injector\Injector: # Create PDF generator as an injector service # This allows you to specify the binary path once and have it set up # automatically by getting the service from the injector. Knp\Snappy\Pdf: constructor: - '/bin/wkhtmltopdf' # Path to your WKTHMLTOPDF binary. Use '`SOME_ENV_VAR`' to define the binary path in .env
use Heyday\SilverStripe\WkHtml; use SilverStripe\Core\Injector\Injector; $generator = WkHtml\Generator::create( // Use Injector->get(Pdf::class) if you don't need to modify options // Use Injector->create() to create a transient service for modifications (e.g. setOption) // Using Injector->get() and making changes will cause changes to be made for all uses of get(Pdf::class) for the entire request Injector::inst()->create(\Knp\Snappy\Pdf::class), WkHtml\Input\Url::create('/'), WkHtml\Output\Browser::create('test.pdf', 'application/pdf') ); return $generator->process();
