Module development and code questions

Hi,

I have been asked to work on website personalization. Basically I have to save the selections that the logged in user made in the website, so that when they log in again they dont have to make the same selections again. I have to all this programmatically.

Could you please help me how should I go about it? Any resources would help.

Thanks,

I have a custom module that builds a custom menu depending on an attribute of the node for a basic page. If $nid = 10, then a custom-menu-10 needs to appear in a region for that page. If $nid = 11, then a custom-menu-11 will appear in that same region. In D7, we just threw the custom menu into a menu_tree_all_data and used $variables['my_custom_menu'] to place the html in page.tpl.php.

To learn more in the new D8 theme API, I've created a custom block in mymodule which has the code I need to determine the node-id() and instantiate the custom menu.

I'm a new Drupal user (though decades of other dev experience) looking for advice on best practices.  I need to develop a multi-client web application with defined (but client-extensible) data model, along with forms for managing data entry and API endpoints to use that data.   Basically I need to build an entire web-app that can be deployed multiple times to different independent clients, but still allow them to take upgrades and bug fixes.

Question to drupal ninjas here. Is it possible to make hook_node_grants() to use "AND" condition from realm instead of "OR"?
What I mean is if for example I have realm1 and realm2, the current functionality is that if the user has gid(grant id) to at least 1 realm, the user has a grant view. What I'm trying to do is to change it to an "AND" condition so that the user needs at least 1 gid from realm1 and realm2 to have grant view access.

Thanks a lot!

Hy guy's,

I'm a beginner in the world of Drupal. Currently, I work on a new module with the "quiz" module (from opigno and Drupal 7) for my internship.

Short explanation: The calculation is used to give a small business owners insights on how they are preforming and if they could have done better.
