I got it figured out , it was actually a theme issue and the way the theme was handling front end submissions. I was able to hook into a custom action hook given by the theme and it worked properly by just hooking acf_save_form(get_the_ID()) into it.
Actually, the acf_form seems to load the values properly only if I’ve saved those values from the backend. It seems the issue is that it simply just doesn’t save to the wp_postmeta table for that post properly so nothing is actually saved , although the data is saved to wp_options instead (confused about this in general) from looking in my database tables and also records the $_POST data to JSON properly upon updating so the culprit seems to lie in the functionality of actually binding the data to the wp_postmeta table.
Anybody know the hooks utilized in this?
Thanks
Updating to 5.3.0+ should fix this issue. The hanging is probably due to an issue with validation_complete inside input.js.
Or possibly is there a way to export the form data that was saved after hitting ‘submit’ to JSON to be utilized elsewhere?
Thanks
