[SOLVED] $_GET Problem

[blufish]

So I have a page like

http://www.frozenoven.com/index.php

when someone goes here I want it to check if

$_GET['where'] is set, if not I want it to go to

http://www.frozenoven.com/index.php?where=home

 

heres part of the code I was attempting at:

if (isset($_GET['where']))
{
if (file_exists($_GET['where']))
{
echo file_get_contents($_GET['where']);
}
if (!file_exists($_GET['where']))
{
echo "<h1 align=center>404 File not Found!</h1><p>Either the file you are looking for does not exist or you typed the url wrong.</p><p align=center><a href='http://www.frozenoven.com'>Home</a>";
}
}
else
{
echo ("<script type='text/javascript'>window.location='http://www.frozenoven.com/index.php?where=home';</script>";
}

 

Thanks in advance for the help!

The way I'd do it is have a folder called 'pages'. Then have the following:

 

<?php

$pages = array('home', 'about', 'help'); // Basically, a list of allowed pages

if(isset($_GET['where']) && in_array($_GET['where'], $pages)) {
    echo file_get_contents('pages/'. $_GET['where'] .'.php'); // Change .php to your page extension
} else {
   echo file_get_contents('pages/home.php'); // Else, echo home page.
}

?>

You're working yourself into a redirect loop here.

 

You're checking if where=home, then redirecting to index.php?where=home, which will run your check again, redirecting you again.

Oh yeah, I missed that. Sure you don't want to ignore the redirect?

If I don't redirect I get an error because it can't find a file file to show.

I'm checking to see if someone is at page:

http://www.frozenoven.com/index.php

When they should be at:

http://www.frozenoven.com/index.php?where=home

 

That's not a loop.

<?php
if(!$_GET['where'])
{
    header("Location: index.php?where=home");
}
?>

this is supposed to load whatever page is set at where like

http://www.frozenoven.com/index.php?where=jokes

[paulman888888]

if $_get(where) = ('') then echo // page not found

else echo //blah

 

i know its not in php form that because i don't understand the brackets stuff.
