The Notices (not errors) are pretty straight forward. You are using variables without checking they are defined first.

 

Without digging through all your code, a simple example....

 

Instead of....

 

switch ($route['view']) {
  // .. rest of code

 

You ought be using....

 

if (isset($route['view'])) {
  switch ($route['view']) {
    // ..rest of code
}
