Drupal 8.x

Hi all,

I'm beginner with Drupal and programming a custom module for my project. I need to remove a value from a multi-value field programmatically (cf my code below). I tried removeItem() function and offsetUnset() function given in ItemList.php but none of them worked.

Hello,
i can't install Drupal8.3.7 with

WAMP 3.0.6
PHP Version 5.6.25
Apache 2.2.23
PostgreSQL 9.2.1.3

Hi!

How can I save my CKEditor configuration? I read that the appropriate file to save is the "config.js" file, but I cannot find it. I am using XAMPP on my local PC to build my site. I've spent a fair amount of time customizing my CKEditor toolbar and don't want to have to re-do all that work again. When I upgraded from Drupal 8.33 to 8.35, my customization was lost.

Thanks,
Richard

Upon creation/saving of a new node in D8, I would like to automatically populate a field, using field values (multiplied) from the latest existing node.

Node A (existing latest node)
Field A1
Field A2
Field A3

Node B (new node, being created)
Field B1
Field B2
Field B3

Field B1 = Field A1 * Field A2 * Field A3

I have been trying to use the Computed Field Module. But I am not sure how to get field value from the latest node into Computed Field.

Any advice would be appreciated.
