In 4.1.6 the following works for me (some_json is a simple textfield):
update_field('some_json', json_encode($array), $post_id);
$json = get_field('some_json', $post->ID);
When I update to 4.1.8, get_field() returns false although the JSON is still stored in the Database (the same way as with 4.1.6) and nothing else changed on our end.
It might be a similar issue as it is in http://support.advancedcustomfields.com/forums/topic/get_field-cant-retrieve-new-post-saved-with-update_field-in-acf-4-1-8/ as the field_key is “temp_key_for_some_json”.
How can I achieve that the Key is “some_json” and not “temp_key_for_some_json”? I have created the field “some_json” through PHP and not the GUI.
My Field in the Database “temp_key_for_some_json” is being renamed in 4.1.8.1 to “field_some_json” (when saving that post) and after that I cannot access the fields contents any longer with get_field(‘some_json’). Why not?
Hi @noisyrabbit
Thanks for the bug report.
I’ll do some testing and let you know what I find.
Before you run the update_field function, does the post already have a value for some_json? If so, was that value saved through the ACF interface? Can you confirm that the correct field reference is saved under the value in the database?
Hi @elliot,
Thank you for your response. My problem does still exist.
Before you run the update_field function, does the post already have a value for some_json?
Yes, the post already has a value for some_json.
If so, was that value saved through the ACF interface?
No, I have set it via PHP with update_field(), as described in my first post.
Can you confirm that the correct field reference is saved under the value in the database?
The Key in my database is currently “temp_key_for_some_json”. With 4.1.8.1 is being renamed to “field_some_json” (when saving that post) and after that I cannot access the fields contents any longer with get_field(“some_json”).
It seems that I can fix this weird issue, when I do the following:
update_field(‘some_json’, json_encode($array), $post_id);
update_post_meta($post_id, ‘_some_json’, ‘some_json’, ‘field_some_json’);
After renaming the Value from “field_some_json” to “some_json”, I can access it with get_field(‘some_json’); again.
Hi @noisyrabbit
Thanks for the feedback. I’ll do some testing and find out why the temp field key is stoping the value from being returned.
