Parsing Filenames

[ereptur]

Ok, someone with fresh eyes let me know what I'm doing wrong with this one!

$dir = opendir("./css");
while (($file = readdir($dir)) !== false) {
   if (($file == ".") || ($file == "..")) continue;
   list($filename,$throwaway) = split('.',$file);
   print "<option value=\"$filename\"";
   if ($filename == $pcss) print " selected";
   print ">$filename</option>\n";
}
closedir($dir);

I get nothing back in the option tags, but if I use $file for the option tags I do get the full filenames. However, I am only wanting the filename minus the extension. So, someone smack me and tell me what I'm doing wrong.

Try this, it might work.

$dir = opendir("./css");
while (($file = readdir($dir)) !== false) 
{
   if (($file == ".") || ($file == "..")) continue;
   $filename = substr($file, 0, strpos(".", $file));
   if ($filename == $pcss) { $selected = " selected"; } else { $selected = ""; }
   print "<option value=\"$filename\"$selected>$filename</option>\r";
}
closedir($dir);

that didn't work. It seems that either method should have worked, but for some reason it's not. I wonder if it has something to do with the string that is being returned by readdir(). Any thoughts.

It's a possibility. I'll see what I can do.

Here we go. On mine, I screwed up the order of strpos().

echo "<select>\r";
$dir = opendir(".");
while (false !== ($file = readdir($dir))) 
{
   if (($file == ".") || ($file == "..")) continue;

   $filename = substr($file, 0, strpos($file, "."));
   if ($filename == $pcss) { $selected = " selected"; } else { $selected = ""; }
   print "<option value=\"$filename\"$selected>$filename</option>\r";
}
closedir($dir);
echo "</select>\r";

This worked for me.

Excellent, this worked great. Thanks for your help Thora_fan!
