In my page.html.twig template file, I'm looking to set classes depending on the content type the page is being viewed. I pretty much have two options, if the page being viewed is a program page, then I want one style applied to the div, if it's anything else, then the other style can be applied.

{% 
  set aside_classes = [
    node.content-type is 'program' ? 'program',
    node.content-type is anything else ? 'standard'
  ]
%}

I know the above code is not proper but it's an example of what I'm trying to achieve.

I would then have the following code below on my div:

<div{{ content_attributes.addClass(aside_classes) }}> 

Am I going about this right or is there a better way to achieve this?

EDIT: Here are my kint variables. Not sure if this helps at all?: Kint Variables

  • With default Drupal config, you should see two classes automatically created on the body tag for all page types in Drupal. I would expect you to see the classes ".path-node" and ".node-type-program". This is done in the html.twig template file with {{ attributes.addClass(body_classes) }} on the body tag. Do these not work for your situation? – Prestosaurus Jan 30 '18 at 21:44
  • I see what you're saying but I'd prefer to add the style to the specific div within the body depending on the content type. Would the following work? node_type is 'program' ? 'program'. But how would I tell it to add 'standard' if it's anything else? – ACanadianCoder Jan 30 '18 at 21:56
  • @ACanadianCoder something like this should work {% node.content-type is 'program' ? 'program' : 'standard' %} – cchen Jan 30 '18 at 22:26
  • @cchen that didn't seem to work. Just got a page error. – ACanadianCoder Jan 31 '18 at 15:06
  • @ACanadianCoder sorry that was not the exact working code..I think the answer below should work, you just need to modify it a little bit to make for the page level template. – cchen Jan 31 '18 at 15:37

Not sure about page.html.twig. Would have to dig around...

In node.html.twig:

{%
  set newClassNameVar = [
    node.type.entity.label == 'Program' ? 'Program' : 'Not Program'
  ]
%}

<div{{ attributes.addClass(newClassNameVar) }}></div>

or:

{%
  set newClassNameVar = [
    node.bundle == 'content__type' ? 'set-yes-class' : 'set-no-class'
  ]
%}

<div{{ attributes.addClass(newClassNameVar) }}></div>

use debug such as {{ dump(_context | keys) }} to see what is available and best suits your use case.

  • I've added my kint screengrab to the original post from my page.html.twig file. Does any of that help? – ACanadianCoder Jan 31 '18 at 15:09
  • I ended up just using your method mentioned above but used {% if node.bundle == 'program' %} and that seemed to work. I still think there's a more elegant way of doing it similar to what @cchen had suggested in the above post but this will work for now. Thanks again! – ACanadianCoder Jan 31 '18 at 15:41
  • updated my answer with two options, credit to @cchen too – Prestosaurus Jan 31 '18 at 16:12
  • Awesome...that works and looks much nicer...however, instead of using the label, is there a way of using the machine name? ex. node.type.entity.machine_name == 'program'. Sorry for being so picky. – ACanadianCoder Jan 31 '18 at 16:36

    I was looking myself and will try some more when I can. node.type.entity.machine_name looks like the right idea. Also I am always a fan of {{ dump(node | keys) }}, it's a lot lighter than kint. {{ dump(_context | keys) }} is a quick way to see everything available such as 'node', 'elements', 'content'... – Prestosaurus Feb 1 '18 at 17:15
