问题 I want to use nochso/html-compress-twig extension to compress all html, inline css and js.But it is the first time that I register a new extension on Twig and I am bit confused about where I should add the following lines in my project: $twig = new Twig_Environment($loader); $twig->addExtension(new \nochso\HtmlCompressTwig\Extension()); I was reading the Twig's documentation but it didn't helped me much as they put the same example and just add the following: Twig does not care where you save

问题 I assumed this would be easy but I am stumped. I have a custom content type that includes an id field. I render these with a basic page template. I have written a small module that creates a block which is populated with data from an external API. Everything works except I cannot seem to figure out how to pass the value of the id from the content of a given page to my module so it can make the API call. It would be a couple of lines of code in straight php, it can't be that complicated in
