Проблема с добавлением комментариев

вопрос

Всем привет, у меня проблема с добавлением комментариев :( Если комментарий добавить через phpmyadmin в нужную таблицу, то комментарий выводится без проблем, а добавить его с сайта не получается и не понятно в чем проблема.

PHP функция добавления комментария

и не понятно в чем проблема

поменьше в движке надо ковыряться, тогда все будет прекрасно работать

pavel31 - 2015-02-284 ноября 2013 13:37 - #18678

Цитата: TheImDim

Я в движке не ковыряюсь, у меня в моём модуле комментарии не добавляются.
Если их добавить через phpmyadmin в нужную таблицу, то комментарии выводятся, а из модуля не добавляются :(

vitnet,
От куда я знаю, это ведь не мой код. От куда он взят?

Ура! добавление комментариев я сделал! Теперь осталось ссдать что бы после добавления комментария обновлялась страница, но не перезагружалась! а только обновлялась.

Смотрите js ошибки после добавления комментария, не мешало бы ссылку на сайт оставить

javascript и php работают, но почему-то не обновляется страница ст реком, после добавления комментария, кстати после нажатия на крестик добавления в избранные таже фигня, значек меняется только после повторного захода на страницу трека. По ходу ajax вообще не работает, странно почему?
