open directory, limit results w/NEXT and BACK links?

[f8ball]

I've looked everywhere on this forum for a similar thread, but everyone of them are written for use with MySQL.

I've built a gallery that opens a directory and outputs thumbs 4 across and 'x' down (however many are in the directory). What I need to do is limit the thumbs to 20 per page and if they exceed 20 I need NEXT and BACK links to appear. Is this even possible with a directory listing or is this only doable w/a MySQL database.

yes; the principle is exactly the same the only thing different is the way you retrieve the items. i would read the files into an array and display array elements 0-19, 20-39,... on each page.

Thanks. That makes sense, but I'm still stuck. I found another thread that had a similar script ... so I've been playing with it and no luck. I'm so use to working with database results .. this is driving me crazy.

ok .. now i've got it except for two things

1) the "displaying 'x' to 'x' of 'x' images' needs to be worked out

2) if you are on the first page and click 'next' it kills the first file and reads the last file from the previous page. I think it has to do w/ $filelist[$i-1]. I've been playing with that, but no success. All my files are labeled 01, 02, 03, etc. for testing.

Here's where I'm at now.

$page = (isset($_GET['page'])) ? $_GET['page'] : 0; 
if ($dir = @opendir("my/directory")){
	while (($file = readdir($dir)) !== false){
		if($file != ".." && $file != "."){
			$filelist[] = $file;
			}
		}
	closedir($dir);
	sort($filelist);
} 

print $page."<< PAGE NUMBER<br><br>";

$filecount = count($filelist);
$limit = 20; // allow 20 images per page

if ($filecount > $limit){
	$filelist[$limit] = $file;
}
$from = $limit * $page;
$to = $from + $limit;
$pages = $filecount/$limit;
$start = $page * $limit;
$na = $page + $limit;
$next = $page + 1;
$back = $page - 1;
$last = $last = round($pages, 00) - 1;
$first = 0;

// count current files
for($i=$start; $i<=$to;$i++){
	if($i == $filecount){
	}
}

print "Displaying ".$na." to ".$start." of ".$filecount." images - ".$pages." Pages to show images on<br><br>";
if ($i < $filecount){
print "<a href=\"$HTTP_SERVER_VARS[PHP_SELF]?page=$next\">NEXT</a>          ";
print "<a href=\"$HTTP_SERVER_VARS[PHP_SELF]?page=$last\">LAST</a>          ";
}
if ($page != "0" && $i!= $filecount){
print "<a href=\"$HTTP_SERVER_VARS[PHP_SELF]?page=$back\">BACK</a>          ";
print "<a href=\"$HTTP_SERVER_VARS[PHP_SELF]?page=$first\">FIRST</a>          ";
}
// list files
print "<br><br>";
for($i=$start; $i<=$to;$i++){
	print $filelist[$i-1]."<br>";
	if($i == $filecount){
	print "END";
	}
}
