Using the transition_post_status, I can’t get update_field to save here. Everything else in the function works. For instance, if I uncomment the two lines that are currently commented, I get 13. What am I missing here?
function do_something_on_save( $new_status, $old_status, $post ) {
//echo get_the_ID(); //returns 13
//exit;
update_field(
'notification_record',
'checking',
13
);
}
add_action( 'transition_post_status', 'do_something_on_save', 10, 3 );
Try using the field key instead of the field name. ACF cannot update fields using the field name for fields that do not already have values.
@hube2 Thanks for responding 🙂
I added the following:
$field = get_field_object('notification_record');
var_dump($field["key"]);
exit;
which gave me ‘field_57cee83c43f92’ as the key
so I updated my code here and it’s still not saving 🙁
function do_something_on_save( $new_status, $old_status, $post ) {
//echo get_the_ID(); //returns 13
//exit;
//$field = get_field_object('notification_record');
//var_dump($field["key"]); //returns 'field_57cee83c43f92'
//exit;
update_field(
'field_57cee83c43f92',
'checking',
13
);
}
add_action( 'transition_post_status', 'do_something_on_save', 10, 3 );
Are you sure the post you are updating has an ID of 13? What type of field are you attempting to update? Is the field a sub field of a repeater or flexible content field? Where are you trying to see if it’s been updated?
I switched to the ‘acf/save_post’ hook instead of ‘transition_post_status’, per a support ticket, and it’s saving now 🙂
I got the post id by echoing out get_the_ID() (see code comments); I just hardcoded it to be sure. This was just a basic text field. To test, I was just saving the post and checking to see that the field had been updated from the edit-post view.
Note: For this to work, I set the priority to 20; leaving it as 1 (before post save) didn’t work.
Thanks for the help.
I have the same issue – ACF functions do not seem to work in update_post, regardless of priority.
The solution for me, because I needed to use post_updated to compare old and new post titles and slugs, was to update the value in $_POST[‘acf’]. E.g:
$_POST['acf']['field_5f19d4ad03a30'][] = ['field_5f19d4b503a31' => $old_title]
In this case, I am saving the old title to a repeater. For this to work you must use field keys, not field names.
Howdy! Could you perhaps attach what your final code looked like? I am having the same problem and cannot get this to work!
Try using the native WP function update_post_meta instead, unless you’re sure ACF has loaded at the time you’re trying to use the function:
update_post_meta( $postid, ‘ReleaseY’, $json->Year );
