Using the Switch Statement Issue...

[phpSensei]

This is my index page for my site...

 

<?php

$action=$_GET['page'];

switch($action){

case '':
index();
break;

case 'view_comments':
echo "here be comments";
break;

}
?>

 

My issue is that when ever a user enters something like this www.localhost.com/?page=dssdasdasdasd,

 

As you can see the "asasasas" is a random string which doesnt exist in my switch statement....

 

HOW can I show an error message for whenever the page doesnt exists?

 

Please try to understand.

Add a default case:

 

<?php

$action=$_GET['page'];

switch($action){

case '':
index();
break;

case 'view_comments':
echo "here be comments";
break;

default:
echo 'Invalid action';
break;
}
?>
