Optional Function Parameters Within Controllers

[eluser]blackhalobender[/eluser]
I'd like to make a variable passed from a URL optional without getting the missing argument error


Any ideas?

Code:

if(!$this->uri->segment(4))
{
   // not present
}
else
{
  // present
}

THANKS xwero!!!

Opps, actually I'm getting errors. Where can I put that?

It looks like that has to go INTO the function and I need to remove the param from it?

Using PHP's optional parameter feature also works....

Code:

function myfunction($param1, $param2 = FALSE) {
  if ($param2 === FALSE) {
    // Do something when param2 isn't supplied.
  }
}

In this example, $param2 will be assigned the boolean false if it wasn't in the URL, but you can easily change it to be whatever you like.
