despero
нашел готовое решение плагин
http://wordpress.org/plugins/wp-favorite-posts/
но цуко возникли некоторые проблемы он работает с куками и базами данных , куки для незарегистрированных пользователей , БД для зарегистрированных . так вот по ходу с БД работает криво , попробовал пару раз добавить/убрать пост "в мой список" и он перестает фурычить я так понимаю значения для поста в базе записалось и нихуя неменяется или хер его знает . И походу если у меня на блоге дофига зарегистрированных пользователей на кнопочки тыцать будут он мне цуко так базу засрет шо пипец , да собственно опять же с базами работает некорректно может кто подскажет так на вскидку как сделать так что бы он вообще только с куками работал а в БД не лез. Может какую функцию нахер выкинуть из кода
