[quote author="TheFuzzy0ne" date="1240532914"]Have you enabled hooks in the config.php file?[/quote]

Yup:

Code:

$config['enable_hooks'] = TRUE;

In the hooks.php I have:

Code:

$hook['pre_system'] = array(
    'class'    => '',
    'function' => 'URLRewrite',
    'filename' => 'URLRewrite.php',
    'filepath' => 'hooks'
);

And in the URLRewrite.php file I have:

Code:

<?php
function URLRewrite(){
    if (isset($_GET['view']))
    {
      $redirect = 'Location: '.config_item('base_url').'page/id/'.$_GET['view'];
      header($redirect);
    }
}
?>

This is my first time using hooks so maybe I'm doing something wrong?
