Directory Listing Error

[Profector]

Hey I've been messing with this script for the last few days now with no luck figuring out why its not working.

I'm trying to list all files in a directory for download by letter name: ie viewfiles.php?letter=a and all files in downloads/a/ will appear on the website. Here is the script:

<?php
$handle=opendir('UMaps/$HTTP_GET_VARS[letter]/');
while($file=readdir($handle)) {
if ($file == '.' OR $file == '..' OR $file == 'index.php') {
echo "";
} else {
$i = 0;
$ls[$i]=$file;
$i++;
}
}
closedir($handle);
sort($ls);
?>

and where I want the files listed:

<?php
$n=0;

while ($n<$i) {
echo "<a class='php' href='http://www.mapheaven.net/UMaps/$HTTP_GET_VARS[letter]/$ls[$n]'>$ls[$n]</a><br>";
$n++;
}

I call the page with maps.php?letter=something and everytime I do this it gives me the error message directory not found. Is it just not possible to pass a variable into this function???? If anyone has a suggestion, please feel free.

$handle=opendir('UMaps/$HTTP_GET_VARS[letter]/');

Your problem is this line 🙂 You're close though. Use this:

$handle=opendir('UMaps/'.$HTTP_GET_VARS['letter'].'/');

The single quotes make whatever's inside of them a literal string, so it wont replace the $HTTP_GET_VARS[letter] with it's value, but instead actually use the name of the variable. As such, it was trying to open the directory, /UMaps/$HTTP_GET_VARS[letter]/ instead of /UMaps/a/

Hope that helps,
Matt
