Not quite sure what this is supposed to fix, to be honest. The original version in the line changed would return a value right away. All you're ending up doing is assigning that to a variable, inside an if statement. Never been a fan of variable assignment inside if statements myself.

Is this fixing an open issue at all? or just casual looking over of the code?

You can look $page_type never declared before.

Gotcha.

Thank you sir.

You're welcome :)
