Module development and code questions

Hello - I was advised that in php.ini, I should set variables_order to "CS" only because we should not use the super global arrays for $_GET, $_POST, $_ENV, and $_REQUEST.  However, if I set variables_order = CS, Drupal core no longer functions correctly.  In particular, the login form on Drupal (core) no longer works.  It does not log in the user and just refreshes the page.  Per php.ini documentation, using those super global arrays creates extra overhead.  Also, per https://www.drupal.org/project/drupal/issues/

I try to port a module that i want to publish, to Drupal 11. 

There have been some changes to the API and i cant get it to work at all. It must be some small detail in namin of something.

I still get:

• 'elif_nofollow' is not a supported key.
• 'elif_noopener' is not a supported key.
• 'elif_noreferrer' is not a supported key.

I have a custom text filter like this:

What are the best ways to audit and review a custom module (or a contrib module) to ensure it is secure, or at least follows best practices?

Hello

I try to add a link appear in /admin for a specific role. This specific role has a few permissions (adding specific content for example) and I would like to hide certain links appear in /admin and to add other links in this same page.

I tried to use the hook MYMODULE_page_attachments_alter but I did not find the way to add links into this.

What solution for this ?

Thanks

What are the steps to follow to add new exposed filter widget for a JSON field added using the Views JSON Source module?

Overview

PHP 8.1 introduced a new data model, Enumerations. Enumerations allow for the creation of custom data models that can only contain a fixed set of allowed values. These enumerations can be very useful when working with Drupal list fields, which are a field type that allows for selection from a predefined set of values. As both enumerations and list field contain a predefined set of values, using Enumerations to back Drupal list field makes for more stable code that is easier to understand, and less likely to fail.
