I’ve used a function to add photographer name and URL (extra custom meta) to uploaded images.
The added data can be retrieved using get_post_meta($id,'photographer',true), for example.
These two meta fields also display in ACF. Which is great, until I go to edit them. The values are not saved on Publish.
I guess that because these values are not added to the ACF image array, ACF can’t save them.
How would I (can I?) go about adding these key => value pairs to ACF’s image array, or whatever else I’d need to do to make these fields editable and save-able as they appear to be in the UI?
Just one thing. I don’t want to be trapped into having to do little tweaks to an ACF supporting file every time ACF is updated to keep the fix working.
Hi @ht,
Thanks for the post.
To add or update meta within ACF fields, I would recommend you make use of the update_field() function. This functions accepts three parameters, in your case, you will need to pass the field_key, $value and the post id that you want to update the posts to.
Thanks, James. Elliot actually fixed the issue shortly after my question, but your tip could be valuable at another time.
