Module development and code questions

Im trying to change the language switcher on my website to not be text but instead look like flags. I have no idea how to do it. I have languages set up using the language module.

Hi,

I'm new on Drupal Ecosystem. How can i create node programmatically with using editor like VsCode.

Thank you so much.

I have created to submit buttons for webform ( save changes and unsubscribe ) , I need to create two different submit handlers to call API for these buttons .. but how can I call different submit handlers in hook form alter 

My 2 submit handlers have keys actions and actions_01 so I called: 

$form['actions']['submit']['#submit'][] = 'update_subscriber';

$form['actions_01']['submit']['#submit'][] = 'unsubscribe_handler';

but on both button submit 1st handler is called 

array_unshift($form['#validate'], 'bncreports_user_register_form_validate');
array_unshift($form['#submit'], 'bncreports_user_register_form_submit');

I have the above in my bncreports_form_user_register_form_alter function. The validation works but the submit does not. Nothing gets executed. Anyone know why this could happen?

Hi everyone,

i want to ask you something, is diff module available for drupal version 9.3.16? i cant find a way to extend the funcionality of my site with this module!

Thank you in advance!

I've created a new custom module and placed it in a clean D9 app which only runs additionally the examples modules.

Drush will not install this module so I stripped out everything but the info.yml and a bare .module file. That's my understanding of the minimum needed for a Drupal custom module.

I've read many sources on what the module.info.yml should say in a d9 paradigm.
