I want to alter a form to make the revision log be required. with drupal 8, I am adding this in a module

$form['revision_information']['#required'] = TRUE;

but the field does not become required. What am I missing?

    I believe there was a similar question this month and if there is an attached widget, it also needs to be set as required.... can you post the form item in the question.

    It looks like this is just a details type, not an input

this was the answer:

$form ['revision_log']['widget'][0]['value']['#required']=TRUE;

thanks for the tip about the widget Kevin

I know this is an old case but wanted to share (for those new comers) my experience on how I managed to nail the issue in D7 for the above case.

Sol: $form['FIELD_NAME'][LANGUAGE_NONE][0]['value']['#required'] = TRUE;

Note: Remember to replace the "FIELD_NAME" part with your referring field.

Cheers.

Generally to make a field required on form alter what you need is

$form['FIELD_MACHINE_NAME']['#required'] = TRUE;

In your case it didn't work because it's not the nested field and it's a group

https://www.drupal.org/project/drupal/issues/2177469

$form ['revision_log']['#required'] = TRUE; 

if you want to make the email field required, the following snippet works

$form['account']['mail']['#required'] = TRUE;
