Question

У меня есть веб-страницу, я работаю, ссылка:

http://nexusdesign.org.uk/irejobs/training-courses.html

Код, который находится ниже. Теперь в бэкэнде я создал записи для учебных курсов, как показано, но эти arent показ. Из чего я могу отце, их следует вытащить из базы данных db_trainings как здесь, так и в отдельном окне функций ниже,

Может кто-нибудь посоветует whats здесь не так?

Answer 1

Из приведенных выше комментариев:

all of the members tables show advertisementexpiry at 0 

Ваш запрос пытается соответствовать что-нибудь с advertisementexpiry> 0. Это означает, что запрос не будет соответствовать ни одной строки, так как ни один не больше 0.

Answer 2

вам нужно, чтобы сломать этот бит t.MemberID <> '' and t.MemberID = m.MemberID and m.advertisementexpiry > 0 and t.active = 'yes'

тест каждый кусок для отладки

t.MemberID <> '' 

выглядит как его не нужно, как я pursuming каждый элемент имеет идентификатор.
