How do you use hook_form_FORM_ID_alter() to alter the USER EDIT form? I'm trying to mark fields on the /user/_uid_/edit screen as disabled.
These are custom fields I've created in /admin/config/people/accounts/fields in D8.

I have this code for another node entity type...

function MODULENAME_form_node_survey_edit_form_alter(&amp;$form, $form_state, $form_id) {
  $form['field_content_type']['widget']['#type'] = 'hidden';
}


This works as expected, and on the node/123/edit screen for a that content type, that field is hidden. (works as expected)

(it gets populated by a migration process, and needs to stay how its set, even if users change other fields...)

My problem is, that I'm trying to disable a field on the USER-EDIT screen, such as /user/123/edit.

I'm trying the EXACT same code structure.

function MODULENAME_form_user_edit_form_alter(&amp;$form, $form_state, $form_id) {
    $form['field_organization_reference']['widget'][0]['target_id']['#attributes']['disabled'] = 'disabled';
}


But it doesn't work.

I've tried throwing in class changes, and other things to alter the input fields, but they don't work.

$form['field_organization_reference']['widget'][0]['target_id']['#attributes']['disabled'] = 'disabled';
$form['field_organization_name']['widget'][0]['value']['#attributes']['disabled'] = 'disabled';    
$form['field_organization_reference']['#attributes']['class'][] = 'borkbork';    
$form['field_organization_name']['#attributes']['class'][] = 'borkbork';
$form['field_organization_name']['widget']['#type'] = 'hidden';


All as attempts to try and change something on the user edit form.

But nothing is working.

Is user-edit the correct form id?   Is there something else I'm missing

Thoughts? Help? Thank you!
Try:

function MYMODULE_form_user_form_alter(&amp;$form, $form_state, $form_id) {
  // Your code...
}


Inspecting element, I see the form id is user-form, which needs to be translated to the machine-readable name user_form

Otherwise, you can always do a standard HOOK_form_alter():

function MYMODULE_form_alter(&amp;$form, $form_state, $form_id) {
  if ($form_id == 'user_form') {
    // Your code...
  }
}


And always clear cache after adding/changing hook names.
