sort problem

[tgavin]

I'm having a hell of a time sorting this alphabetically. Could somebody help?

$currentdir = SITE_PATH.$directory;
$new_file = null;
@$dir = opendir($currentdir);
while($file = readdir($dir)) {
    if(!is_dir($currentdir."/".$file)) {
        $file = $file . "','";
        $new_file .= $file;
    }
}

Are you just trying to sort the files in a directory alphabetically?

Stick them inside an array, then use asort()

@$dir = opendir($currentdir);
while($file = readdir($dir))
    if(!is_dir($currentdir."/".$file))
         $files[] = $file;
    
asort($files);

Instead of a flat file, any thoughts of creating an array of arrays ? You can then iterate through and use asort().

Thank you.

The problem that I have is that the $new_file var is put into a pulldown, which then displays filenames of images in the dir.

I can't really toy with the code, and what you gave me doesn't work too well. Meaning, instead of each image being an <option>, all of the images in the dir showed up as one <option>. Is there a way to sort with the code that I supplied?

If you want to get all the files inside $new_file spaced with a comma, just use implode

$new_file = implode(",", $files);
//now $new_file = 'file1,file2,file3...' 

or to get each inside an option, loop through the array

foreach($files as $file)
  $dropdown .= "<option>$file</option>";
