Is there a hook for node after save?

Question

How do I unpublish translations when the english content is unpublished? I tried to unpublish the language content programmatically when I am unpublishing the english content in the hook_node_update() but it returns below error.

$languages = getLanguageList();
$currLanguage = \Drupal::languageManager()->getCurrentLanguage()->getId();

if (!$node->status->value) {
    foreach ($languages as $languageId => $language) {
        if ($languageId != 'en' && $currLanguage == 'en') {
            if ($node->hasTranslation($languageId)) {
                $transNode = $node->getTranslation($languageId);
                $transNode->setPublished(false);
                $transNode->save();
            }
        }
    }        
}

Error :

Uncaught PHP Exception Drupal\\Core\\Entity\\EntityStorageException: "Update existing 'node' entity revision while changing the revision ID is not supported."

So I guess if I can do this after saving the node it would work. Is there a hook for node after save. Or is there a way to unpublish language contents of a node while unpublishing the source language(English)?

Answer 1

In Drupal 8 you should use hook_entity_update().
This hook runs once the entity storage has been updated.

Answer 2

Could it be this you are looking for:

Entity::postSave(EntityStorageInterface $storage, $update = TRUE)

https://api.drupal.org/api/drupal/core%21lib%21Drupal%21Core%21Entity%21Entity.php/function/Entity%3A%3ApostSave/8.6.x

Answer 3

You could try in hook_pre_save so that should be before the main node has been effected
