Is it possible to adapt this plugin for version 4? #16

Is it possible to adapt this plugin to version 4? Or can you help me with writing some functionality similar this?))

The reason this does not work on ACF4 is that I call functions that are only available in ACF5 to get the list of field groups attached to a post and get the list of fields in each field group. These functions are acf_get_field_groups() and acf_get_fields(). There would need to be code added to detect the ACF version and do something different depending on that. I don't even know if this can be done in ACF4 or how.

My suggestion would be to build a filter for only the specific fields where you need this functionality. There is a document on the ACF site here https://support.advancedcustomfields.com/forums/topic/2-way-relationships/ and I have an alternate method/example here https://github.com/Hube2/acf-filters-and-functions/blob/master/acf-reciprocal-relationship.php

You can do this for ACF4. You can request the groups for ACF4 using apply_filter('acf/get_field_groups',$array) and loop over the fields-groups using acf_get_fields() to get the fieldinfo.

I use this method to support both ACF4 and ACF5 in my plugin. But only because acf4 uses save_format and acf5 uses return_format on some values.

ACF 5 was released to WP repo some time ago, this should no longer be an issue
