Module development and code questions

Hello, in Drupal 7, with webform 4.19 module, how can I add multiple working "submit" button that actually submit my webform.

In a custom module, I wrote something like that:

$form['actions']['submit_2'] = array(
  '#type' => 'submit',
  '#value' => t('Submit 2'),
);

Hi,

I have been given a code in which I have been asked to use dependency injection.  The code goes as the following:

/**

public function build() {
$build = [];
$sources = '';

Hi,

I'm using Drupal 8.7.5.

I want to disable or add permission (only administrator can access) to an existing route , path is /node/add/article  because I've built a new form for creating article, I want editors use the new form instead of the default form at url /node/add/article .

How can I do this?

Thank you

I have a site with Drupal, as well as the modules "Message" and "Token".

I created a custom module based on the module "Message example".

I created for entities, a display mode called message_activity_stream.

I created a token to display the rendered entity of the nodes and it works.

Now I want to create a custom token to display the rendered entity of the author of the message.

HI I have a function as follows that returns a form with all the values populated, What I have been doing is then hiding the fields I don't want but was wondering if there is a way to just display the fields I do instead, can anyone assist please, for example how would I display just the title field.

thanks
