Updating parent page when posting comment

[chrisgwynne]

Is there any way to update a field in the parent page when posting a comment?

Yes, you can use a hook to run your logic for specific events, e.g. did-save-comment.

[chrisgwynne]

c::set('comments.hooks.did-save-comment', function ($comments, $comment) { $page = $page->$parent()->update(array('lastupdated' => 'd-m-Y H:i:s')); return false; });

I'm not the best with this unfortunately florian, keeps throwing up errors.

$page is undefined in config.php. You can access the page object using the $comment variable:

c::set('comments.hooks.did-save-comment', function ($comments, $comment, $commentPage) {
  try {
    $comment->page()->update(...);
  } catch (Exception $e) {
    // do something with the exception
    echo $e->getMessage();
  }
});

Some other notes:

• $page->$parent() will never work, the dollar-sign ($) is used only when accessing a variable, not methods and properties: $page->parent().
• I think 'lastupdated' => 'd-m-Y H:i:s' should be 'lastupdated' => date('d-m-Y H:i:s').
• You don’t need to return anything in the did-save-comment hook, as the return value is ignored.
