如何根据当前用户的情况显示区块？

Question

I have a Drupal 8.7 site with Drupal Commerce 2.14

I also installed TWIG Tweak module.

I want to display text based on certain conditions of the current user in my TWIG file.

Thanks for your help.

I write a comment for each condition I want.

Here is the code of my page :

Answer 1

Try implementing in a custom module a block plugin and a theme function. In the "build" method of the block plugin, add all your logic and just pass the results as variables to the block template.

Answer 2

You can restrict blocks to custom roles you've created or you could create.
