Drupal 8.x

Hi all, I currently want to edit the HomePage content type to replace just the image fields with an image field that has a custom URL text link on top of the image field but I don't know how to do complex layering in the Drupal CMS? I am a complete newb so any help would be greatly appreciated.

TIA

Jason

I saw this two value is view:

what is difference between {{ arguments.webform_submission value }} and {{ webform_submission values }}

Feeds is giving me a hard time, producing WSOD with the error:

Trying to search for some modules and every 4 out of 5 modules which I find shows this at the top

'This project is not covered by Drupal’s security advisory policy.'

Seriously, why doesn't drupal just get rid of them.

Can someone tell me how I can install Composer on a One.com website (www.seniorama.one)? I need this because I get the following error: Please install the PHPMailer library by executing 'composer update' in your site's root directory. (Currently using PHPMailer library version Missing).

Hi all

I have a module in D7 that I'm trying to change for D8.
It uses a hook form_alter to fo various things after a particular form is submitted.

I'm struggling to find how I get the submission status in the hook.
So has the form been submitted?

In D7 I used if(isset($form_state['input']['submitted']))

What is the syntax in a hook to check if a form has been submitted? I can't find an example anywhere.
