hook_add_form() gets $entity_type and $entity as parameters, but hook_form_alter() does not have any of those parameters.
How do I get the entity type and the entity object in hook_form_alter()in Drupal 7?

I think that it should be possible to do something like this.
if ($form_state->getFormObject() instanceof \Drupal\Core\Entity\EntityFormInterface) {
$entity = $form_state->getFormObject()->getEntity();
$entity_type = $entity->bundle();
}
UPDATE: In Drupal 7 it should be done like this:
$node = $form['#entity_type']; // E.g this could be, (#node, #user etc.)
Take a look at this site, drupal discussion.

You may also want an if like in this answer to make sure you're operating on an entity form before making these calls.– sonfdCommented Apr 30, 2018 at 12:54

1This isn't right - nodes are just one type of entity, you'll never find any other type of entity in
$form['node']– Clive ♦Commented Apr 30, 2018 at 13:26
Entity types each implemented their own form in D7, there wasn't a generic one. You're at the mercy of what the author of each bit of code decided at the time.
For example you can find consistency with some of the core entity types:
- node ->
$form['#node'] - user ->
$form['#user'] - comment ->
$form['#comment']
But not all the way through:
- taxonomy_term ->
$form['#term']
You might find it easier to target the specific types of entity you're interested in, determine what the correct array key is for each, and store them in a map somewhere for later access.
