A little help understanding the controller

[eluser]intoitdaily[/eluser]
Holy Hell that was easy! It literally took me like 3 minutes to make it work! all I did was add

Code:

$route['blog/:num'] = 'blog/id';

to my routes.php file.
In my controllers I changed all the

Code:

$this->uri->segment(3)

to be

Code:

$this->uri->segment(2)

and in my views I changed all the anchors from

Code:

<?=anchor('blog/id/'. $row->id .'/', $row->title); ?>

to

Code:

<?=anchor('blog/'. $row->id .'/', $row->title); ?>

so simple! The only thing is in a large application, you have to stay on top of your routes if this is something you do often. It can get a little bit confusing if you forget to change a redirect link or something in a view or controller. Thanks again guys!
