Twig theme variables

Question

I am working on creating a theme from scratch for Drupal 8 and I am 90% of the way there. I do have a question on how to access variables in the

{{ dump() | raw }}

I have created a page.html.twig and the {{ page.BLOCKNAME }} is working great. But when I try to place {{ title }}, or any variations, I get NULL or nothing at all.

I can see the title in the dump(), but it has ["string":protected]=> so I am not able to access. I was able to create a new block region and move the title there, but the title will not be in the same place from page to page. I would also like to access the content type, node ID, and node url, with some other custom fields I created, but I can't seem to get to those either.

In summary, how do I use the dump() and actually get to the variables that are presented?

Answer 1

If you wanna see all variables available in your twig template file in Drupal 8 use {{ kint(_context) }}. Don't forget, you must enable kint in devel module settings.

Answer 2

In the page template you shouldn't be printing blocks directly. Blocks should be always printed inside a regions. More information about how to add your custom region can be found here.

If you are printing an already existing region the syntax for that is:

{{ page.region_name }}
