modx_user_attributes has extended collumn that stores data in some format like
{"parent_name":"\u0412\u044f\u0447\u0435\u0441\u043b\u0430\u0432\u043e\u0432\u043d\u0430","document":"\u043f\u0441\u043f","document_create":"","number":"21414441","date_create_document":"","ICQ":"","Skype":"","webmoney_ru":"5332545452154","yandexmoney":"","banks":"","sent":"true","login-updprof-btn":" \u0420\u0435\u0434\u0430\u043a\u0442\u0438\u0440\u043e\u0432\u0430\u0442\u044c \u043f\u0440\u043e\u0444\u0438\u043b\u044c "}
probably it is JSON format, but I’m not sure.
And Login.Profile works with this field when you activate extra-fields.
So I need to read\write from\to this field in order to work properly with Login.Profile and modX.
How can I do this?
