Question

I know this kinda seems like a stupid question and with more research i might be able to find the answer but i have a deadline to please help.

Using codeigniter im trying to see if the ‘ID’ in the url is ‘uID’ (user id) or ‘sID’ (system id).

the code im using is:

    if(isset($this->input->get('uID'))) {
        $getID = $this-input->get('uID');
    } else {
        $getID = $this->input->get('sID');
    }

when i use that i get a server error saying website is temporarily down or under constrcution. Any ideas?

Thanks in advance for the help. Usually i would spend more time searching for the answer myself but i just dont have time tonight.

Answer 1

The warning you’re getting is probably a 500 error — meaning your server is not set up to display errors to you, or you don’t have it enabled in your index.php file.

The error you’re getting, but not seeing is: “Fatal error: Can’t use function return value in write context” because you can’t use isset on a function.

If you could it wouldn’t do what you’re expecting as CI’s $this->input->get('key') always returns a value — it returns false if the key does not exist.

Therefore, to accomplish what it seems you’re trying to do, you’d write:

$getID = $this->input->get('uID') ? $this->input->get('uID') : $this->input->get('sID');

Based on the comment below, I thought I’d also provide it in a way that makes sense to you:

if($this->input->get('uID')) {
  $getID = $this->input->get('uID');
}
else {
  $getID = $this->input->get('sID'):
}

The two solutions are functionally the same.
