[Resolved] Trying to get property ‘ID’ of non-object

[Michael]

I’m seeing the following (with debug mode on), but only when looking at a specific backend admin page (for the Pods plugin). Obviously the first four relate to another plugin, but the fifth one points at the GP 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

Notice: Trying to get property 'ID' of non-object in /Users/Michael/mampsites/ks-demo5/wp-content/themes/generatepress/inc/meta-box.php on line 52

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 ) {

Do you think the error is with GP (and Slide Anything) or Pods?

Many thanks

Hi there,

does the notice still appear if you temporarily disable the Slide Anything plugin ?

[Michael]

Yes the error notice does still appear (but obviously the other four Slide Anything errors aren’t there).

BTW, I do have some PHP functions on the site, but only via Snippets (i.e. nothing in functions.php), and I’ve also tried disabling all those without finding the culprit.

Hi there,

The last one there looks like something we can fix in the next GP version.

The other ones are from that plugin – you’ll need to report it to them.

Thanks for the heads up!

[Michael]

Thanks Tom and David,

Good to know, and yes – I’ll be in touch with Slide Anything.

Cheers

Hello again – re-starting this thread as the same thing is happening for me (line 52 again).
GeneratePress Version 3.0.4
GP Premium Version 2.0.3

It seems to be triggered by the Pods backend admin screens. Here’s some details around the notice (from Query Monitor):

I’ve added it to the 3.1.0 milestone here: https://github.com/tomusborne/generatepress/issues/246

Thanks!
