I'm trying to access the comment field value in controller. With the following code I'm able to access the particular comment object.

$comment = \Drupal::entityManager()->getStorage('comment')->load($commentID);

When I try print_r for the $comment variable, I can see the fully loaded comment object. enter image description here

I understand I cannot access the values by traversing the object since the values are protected. I tried $comment->get('subject')->value function, this time its looping and doesn't return any results.

How do I achieve retrieving the value of specific fields associated with comment entity?

It is better to use kint() function of the devel module for debugging entities because you will get also a list of available public methods.

You cannot get all comment fields values by looping them as different fields have different array result structure.

Using $comment = \Drupal::entityTypeManager()->getStorage('comment')->load($commentID) you get full comment object.

$comment->get('comment_body)->value you get comment body value as it uses some text format (eg. full html).

You also can covert comment object to array $comment = $comment->toArray().

  • I wouldn't recommend working with the return value of toArray() but it is very useful to use with kint()/debug()/var_dump(). It doesn't contain computed properties like ->entity, though.

  • Thank you @Andrew Nim and Berdir, the kint() function of devel module helps. PHP print_r should not be used for complex object with lot of iterations, I got it.
