if statement switch - php

Question

<?php
if ($_GET['user_id']) $content = $_GET['user_id'];
else $content = $_GET['content'];
switch($content) {
//The default page
default:
include_once('main.php');
break;
//The news related stuff
case 'news':
include_once('news.php');
break;
//Show the profile of a user
case 'user_id':
include_once('profile.php');
break;
}
?>
index.php?user_id=id won't work. Any ideas?

Answer 1

Maybe you intended this:
if (isset($_GET['user_id'])) $content = 'user_id';
Instead of:
if ($_GET['user_id']) $content = $_GET['user_id'];
else $content = $_GET['content'];
Then the switch would execute the user_id case and include profile.php.

Answer 2

the default case needs to be the last one.
switch($content) {
//The news related stuff
case 'news':
include_once('news.php');
break;
//Show the profile of a user
case 'user_id':
include_once('profile.php');
break;
//The default page
default:
include_once('main.php');
break;
}
Plus, you said that this doesn't work: index.php?user_id=id
The $content variable is being populated by the value of user_id in the _GET string, therefore if you wanted to see something other than the default page, you'd have to do one of these:
index.php?user_id=news
index.php?user_id=user_id
This probably isn't how you want it to behave, but given your code, this is what it's doing...
