how do I prevent error display if missing argument in URL? - El Forum - 08-29-2010

I noticed that if I have this URL like this
www.example.com/profile/id/4
it will display the profile of 4.
But if someone enters with this URL
www.example.com/profile/id
Where id function is missing an argument, it generates an error. I don't want that error displayed at all. I tried "(!isset($id))" condition but it generated the error before it could reach that condition.
How do I stop that? And redirect the page back to the index function of the given class?

You can try giving it a default, use something like
Code:
function id($id = NULL)
{
if($id === NULL){
//redirect
}

I know this is a little bit of an older post but I am using CI 2.0 and found this method to be simpler. This was the first post I found when searching how to do this so I thought I whould share how I'm doing it.
Code:
public function my_function($id='') //set the field here so it won't return false
{
if($id =='') // if it's empty
{
//redirect or show content if empty here
}
}Hope this helps
