Best way to solve unwanted uri characters.

I am assuming this ID is referencing an ID within a table - therefore, you don't just want to determine if it's numeric and allow it to run.

In the model that is returning data for this controller - have it checks the num_rows() and return FALSE if it's 0, then plan accordingly within your controller.

This way, someone can't pass /view/29834798327493249873294798324783274082378047 and your site go "WTF!?"
