Недавно я преобразовал старый код mysql в mysqli, и я думаю, что чего-то не хватает. По какой-то причине теперь я ничего не получаю в базе данных mysql, и я не получаю подсказки о каких-либо предупреждениях. У кого-нибудь есть идеи, что мне не хватает?Нет данных, получающих базу данных PHP/MSQLi

Когда вы отлаживаете это, выполняются ли запросы к базе данных вообще? Каков ответ из базы данных? – David
Проконсультируйтесь по следующим ссылкам: http://php.net/manual/en/mysqli.error.php и http://php.net/manual/en/function.error-reporting.php и примените это к своему коду. –
Btw, это недопустимый синтаксис 'if (isset ($ _ SESSION ['user'])! =" ")' И ваш код выглядит очень знакомым. Изменить: Ах, да, здесь http://stackoverflow.com/questions/35069604/login-page-passing-session вместе с несколькими вашими вопросами, которые выглядят одинаково и без решения, но с ответами. –
