Ситуация такая :
на главной странице выводятся все статьи которые есть в базе данных,
Так же есть меню с разделами, каждый раздел отвечает за определенную тематику,
Суть проблемы в том что с БД на главную страницу выводятся, а вот по разделам нет, и пришлось написать в конфиге:
ini_set('display_errors', 'on');
ini_set('error_reporting', E_ALL);
и мне выдало такие вот ошибки:
Notice: Undefined index: view in Z:\home\test.local\www\index.php on line 10
[Денвер: показать возможную причину ошибки]
