Hi there, because there isn’t a “Meta Box Block” Forum yet, tagging this in General.

I want to get info on the Active Post WHEN EDITING, so when editing the blocks.

I’ve tried a few options that usually work for me, like get_the_ID(), filter_input( INPUT_GET, 'post', FILTER_SANITIZE_NUMBER_INT ) but they don’t seem to work, because this is an ajax call probably.

Any possibility to let me get to the currently editing post ID?

Yes, that’s right. The plugin uses ajax to render the block, and the post ID isn’t passed to the block. get_the_ID() probably will work only when viewing the post on the front end.

Just curious, why do you need the post ID?

Using my implementation of your Meta Box Block I can enable users to query other parts of the posts data as well. A very simple example for instance is a custom block that will show the terms of a category on the post. But for that, I will need at least the post ID.

Other things might be author of the post, publish-date, or pulling in other custom field (not block) field-data. That last one seems far fetched but why not if it can be done?

As you said, it works when rendering front-end. But that experience is somewhat off when, while using Gutenberg, I can’t get to the post id and use that.

Hi, I got it. I’ll add the post ID in the next version.

Changed line 99 in MetaBox.php into:

call_user_func( $this->render_callback, $attributes, $is_preview , $post_id );

Adding the $post_id does the trick for me. 🙂

Oops, I forgot to pass the param to the render callback function. Thanks for your help!

LOL, was just about to edit my previous comment that I spotted the change in the docs, but not in the actual source-code.

Thanks for the quick fix. It worked out marvelously!
