$_GET error

Hi, I have a really weird error...

phpfile.php

PHP Code:


			


$year = $_GET['year'];

        

        if(is_numeric($year) || $year == 'current')

        {

        

            $file = 'subs/economy/' . $year;

            

            if(file_exists($temp->getFile($file))) 

            {

            

                $temp->view($file);

                

            }

            

            else

            {

            

                $data['msg'] = 'Sidan finns ej';

                $temp->view('error', $data);

            

            }

            

        }

        

        elseif(!isset($year))

        {

        

            $year = 'current';

            $temp->view('subs/economy/' . $year);

        

        }

        

        else

        {

        

            $data['msg'] = 'Sidan finns ej';

            $temp->view('error', $data);

        

        }

Viewing phpfile.php?year=2009 brings up the template subs/economy/2009.php. Viewing 2008.. well you get the point.

Problem is though, that if I'm just viewing phpfile.php it should set $year = 'current', but it gives me an undefined index error. Any ideas how I can set so if they give no parameter in the url, it should set the parameter to 'current'(it doesn't have to DISPLAY that in the url though)?

You need to check if the year was provided, if not use current as a default.

PHP Code:


			
$year = isset($_GET['year']) ? $_GET['year'] : 'current';

Yea, I tried like this:

PHP Code:


			
if(isset($_GET['year'])) $year = $_GET['year'];

But that didn't work. Your code worked however. So thanks!

His worked because you were not setting a default value if none was found, so PHP was using a[n] ''. <-- {Blank Space}
