Sometimes it’s useful to access Twig templates from a Symfony repository, one could argue that this goes against a repository’s role, but if you think of Twig template files or Twig strings perhaps grabbed from a database as data, then this coincides nicely with the function of a repo.
These arguments aside, whatever your situation, if you need to render Twig from a Symfony repository, you do NOT have to pass the Twig container from a controller to a repo to access Twig — just initialize a new Twig Container object then render it’s contents as illustrated in these two repo methods below.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 | function getEmailHeaderNew(){ $TwigContainer = new \Twig_Environment(new \Twig_Loader_String()); $path = $this->container->getParameter('kernel.root_dir').'/../Resources/views/email-header.html.twig'; $emailHeader=@$TwigContainer->render(file_get_contents($path) ); return @$emailHeader; } function getEmailFooterNew($site=''){ if(empty($site)){ $site=$this->siteCanonical;} $site=str_ireplace('www.','',$site); $TwigContainer= new \Twig_Environment(new \Twig_Loader_String()); $path = $this->container->getParameter('kernel.root_dir').'/../Resources/views/email-footer.html.twig'; $emailHeader=@$TwigContainer->render(file_get_contents($path),array('site'=>$site) ); return @$emailHeader; } |
