I'm using the latest version (ids has changed lately) 4.0.3.
And I fill the custom fields automatically with Ajax.
I add new posts with the following kind of URL
then AJAX load the custom fields values that I copy to their fields with the following JS:
jQuery('#acf-field-email').val( question_array['email'] );
For dates I ended up using a text custom fields too. But it's not that disturbing.
Could you tell me how to fill this image custom field please?
I wish I could use the following JS line:
auto_insert_image( question_array['attached_file_id'], question_array['attached_file_src'] );
