Codeigniter没有传递URI段

Question

I'm using codeigniter for a project.

The URL is segmented like this:

example.com/admin/events

example.com/admin/events/add

I have a class called Admin which has a function called events

function events($data)
{
  echo $data;
}

this will echo 'add' for the events/add page but when I try and access the events page alone i get an error

Missing argument 1 for Admin::events()

I thought that I could make two functions, one with a variable being passed and one without but apprently php doesn't allow that.

Fatal error: Cannot redeclare Admin::events() 

How can I make this work? Thanks.

Answer 1

Try that

function events($data = NULL)
{
  echo $data;
}
