I have imported advanced custom fields from one of my other site and now I want to add few more options to those fields but I can't figure out how to do it via Dashboard? I have imported the field using php export/import option of the plugin. Is there anyway that imported fields shows up in Field Groups section in Dashboard?
Fields added by PHP are not shown in the Dashboard.
Recently, I came across this post in the User Submitted Fields section of ACF forums: PHP Recovery Tool.
The author posted a plugin in GitHub, Advanced Custom Fields Recovery Tool from PHP Export. Haven't tested, though.
Use this plugin to import fieldsets from PHP exports. Do not use this for your workflow of importing and exporting. Use it only as a recovery tool when you lose the original database and XML files.
