Drupal 8.x

Hi all,

I am new to drupal.  I created a module called project_1 and using this module I get data from users and push them to the database table called "project_1_table".  Then I created the project_2 module.  In this module, I created a class that extends to the formBase.  Here I tried to get the data from "project_1_table" in the submitForm method.  But the data is not available.  I want to push that data to "project_2_table".  Please help me...  

I have multiple sites(multiple domains designed for various countries) serving almost similar content.

Now, is there a way that while content editing I can mark the content with <link rel="alternate" hreflang="COURNTRY-LANGUAGE"> so, that the applications are not impacted in terms of SEO.

I have Ubercart (8.x-4.0-alpha5 with Drupal 8.7.3) installed - products are set up to with FIle Downloads (either MP3 or PDF).   User can purchase the product and get email to log in to the drupal site BUT nothing shows when the log in on the User page - no Files tab - no Orders info.

Hello everyone,

As part of a migration from drupal 7 to drupal 8, I currently have a rather original node display method that I'm trying to reproduce to Drupal 8, but without success.
Currently on Drupal 7, this method is filled by a custom preprocess that I try to remove in favoir of views / entity reference.
