I am coding navigation for a website and am using this code for every link in the navbar:

<?php
$default = "home.php";
$allowed = array (
'index',
'example',
);
if( isset( $_POST["P"] ) || isset( $_GET["P"] ))
{
$page = isset($_GET["P"]) ? $_GET["P"] : $_POST["P"];

if( in_array( trim ( $page ), $allowed ))
{
$file = $page . ".php";
if( (file_exists( $file )))
{
include( $file );
}
else
{
include( $default );
}
}
else
{
include( $default );
}
}
else
{
include( $default );
}
?>

Currently it searches for files in the folder where index.php. My question is how can I make it search for files in a sub folder? I have all my sub pages in 'pages' folder. Im guessing i have to change this line:

$file = $page . ".php";

But I dont know how to change the path correctly. I think the period in the middle means "current folder" which I have to change to reflect the path..

I got this from: http://scriptplayground.com/tutorials/php/PHP-Navigation/

My knowledge of php is limited so may this be inaccurate.

The . is the string concatenate operator in PHP so $page . ".php" is adding .php on to the end of the page variable which its getting from the post. So + Show Spoiler [code] +
should work for you.

It's also checking the $allowed array to see if its a valid page so make sure all your included pages (just the page name, not folder & .php extension) are included in that array.

Thanks alot! That did the trick, though I had to first remove the first forward slash from "/pages/". -> "pages/". It seems I had confused the . when I was reading about include paths in php.ini

Thanks for your help!

$file = "/pages/" . $page . ".php"

Here you're linking to ROOT/pages/NAME.php, and without the first / you link to HERE/pages/NAME.php

That's how paths work.

What . means in the code is concatenation of strings. So "bubba" . "babba" = "bubbababba".

I'll pay you for SC2, then for the expansion, then for the next expansion, and then for battlenet and then I'll realize you waited too much to give me the game, that I grew too old, and I'll return the hate 1000x times
