Trying to update GUID on a attachment using the wp_update_post() function but its not updating GUID nor its throwing any error.
Example code:
$post = [
'ID' => 45,
'guid' => 'https://example.com/foo.png'
];
wp_update_post($post);

Why need to update guid?birgire– birgire2019-03-29 07:20:32 +00:00Commented Mar 29, 2019 at 7:20

I'm not updating GUID for actual post but for attachment. I am planning to serve images from a image hosting site rather than serving from me. It works fine but I need to update GUID for that.Harry– Harry2019-03-29 07:25:30 +00:00Commented Mar 29, 2019 at 7:25

Why? You are aware that the GUID has nothing to do with the post's permalink, right? It's just an identifier. Changing the GUID won't change a post's URL.Jacob Peattie– Jacob Peattie2019-03-29 11:24:33 +00:00Commented Mar 29, 2019 at 11:24

Turns out WordPress do not recommend updating GUID thus its disallowed.
But we can update it using sql query:
global $wpdb;
$wpdb->update($wpdb->posts, ['guid' => $newGUID], ['ID' => $postID]);

I'm sure it would have been intentionally disallowed to prevent changes to it, while it's fine for attachments, preventing changing it in most cases was probably a good idea given it's not supposed to change.majick– majick2019-03-29 09:43:18 +00:00Commented Mar 29, 2019 at 9:43

Yes. changing GUID is not wordpress recommends. But sometimes it has/needs to be changed.Harry– Harry2019-12-22 16:21:02 +00:00Commented Dec 22, 2019 at 16:21
