Trying to get property ‘ID’ of non-object

Hi there – great plugin, so a big thank you. I hope this is a helpful piece of feedback…

Previously, an issue was raised about Trying to get property ‘ID’ of non-object. I have stumbled across the same issue, but only in a specific situation…

I’m seeing the following (with debug mode on), but only when looking at a backend admin page for the Pods plugin. The first four errors relate to the Slide Anything plugin, and the fifth one points at the GeneratePress theme.

Notice: Trying to get property 'ID' of non-object in /Users/Michael/mampsites/ks-demo5/wp-content/plugins/slide-anything/php/slide-anything-admin.php on line 437

Here are the corresponding lines of code:

$info_added = get_post_meta($post->ID, 'sa_info_added', true);
$info_deleted = get_post_meta($post->ID, 'sa_info_deleted', true);
$info_duplicated = get_post_meta($post->ID, 'sa_info_duplicated', true);
$info_moved = get_post_meta($post->ID, 'sa_info_moved', true);
if ( $blog_id && (int) $blog_id === (int) $post->ID ) {

I raised this with GeneratePress and they’ve agreed it needs a fix.

Perhaps this is something that could be looked at again?
