Reply To: How to get current post ID in block template on edit screen?

Digging through code, it appears that Gutenberg blocks are just custom post type. What’s happening is that block (and so their previews) are standalone: $post_id is actually the block ID! On the frontend, blocks are rendered inside a post, but it’s not always the case. So the problem is a little trickier than I first thought…

I found a temporary workaround though: add this (second line) in /wp-content/plugins/advanced-custom-fields-pro/includes/gutenberg/blocks.php line 403:

`
// render_callback vars
$content = ”;
$is_preview = true;
$block[‘data’][‘post_id’] = acf_maybe_get_POST(‘post_id’);
`

Next edit your custom block template, add this at the top:

`
if(!$GLOBALS[‘post’] && $block[‘data’][‘post_id’]) {
setup_postdata($GLOBALS[‘post’] =& get_post($block[‘data’][‘post_id’]));
}
`

And don’t forget to add this too at the end:

`
wp_reset_postdata()
`

Now you can access current parent post datas. Functions like the_title() work too.

Hope it helps, and hope ACF team will find a cleaner way to add this feature 🙂
