Filename without extension (explode?)

[owainhunt]

I've got a file upload system on my site but for a new version I'm adding a few features. One of these is a page that automatically creates thumbanils of images and outputs them to the browser.
What I need to be able to do is get the filename of an uploaded (or any) file, without the extension, so I can create my thumbnails and rename the thumbnail with the same name plus "_small".
Example: User uploads "cockatoo.jpg". I create a thumbanail called "cockatoo_small.jpg" and all is well!
How can this be done?

check out the gd lib... here is some code i wrote, but have never gotten the focking chance to use because i can't get jpeg support installed right. argh... anyways i hope it helps.

this assumes that you uploaded the file using a post form, and named the file field "new_photo"

BEGIN CODE *

if($new_photo != 'none') {
if(eregi(".[^.]+$", $new_photo_name, $matches)) $extension = strtolower($matches[0]);
if($extension == ".jpg" || $extension == ".jpeg") {
rename($server_root."employee_photos/".$employee_id.".jpg", $server_root."employee_photos/".$employee_id.".jpg.tmp");
if(copy($new_photo, $server_root."employee_photos/".$employee_id.".jpg")){

			// GD LIB STUFF
				$im = imagecreatefromjpeg($server_root."employee_photos/".$employee_id.".jpg");
			$array = getimagesize($server_root."employee_photos/".$employee_id.".jpg");
			$original_width = $array[0];
			$original_height = $array[1];
			if($original_width > $original_height) {
				$thumbnail_height = round((80 * $original_height) / $original_width);
				$thumbnail_width = 80;
				$employee_photo_height = round((250 * $original_height) / $original_width);
				$employee_photo_width = 250;
			} else {
				$thumbnail_width = round((80 * $original_width) / $original_height);
				$thumbnail_height = 80;
				$employee_photo_width = round((250 * $original_width) / $original_height);
				$employee_photo_height = 250;
			}
			$thumbnail = imagecreate($thumbnail_width, $thumbnail_height);
			$employee_photo = imagecreate($employee_photo_width, $employee_photo_height);
			imagecopyresized($thumbnail, $im, 0, 0, 0, 0, $thumbnail_width, $thumbnail_height, $original_width, $original_height);
			imagecopyresized($employee_photo, $im, 0, 0, 0, 0, $employee_photo_width, $employee_photo_height, $original_width, $original_height);
			imagejpeg($im, $server_root."employee_photos/".$employee_id.".jpg");
			imagejpeg($thumbnail, $server_root."employee_photos/".$employee_id."thumbnail.jpg");
			imagejpeg($employee_photo, $server_root."employee_photos/".$employee_id."employee_photo.jpg");

		} else {
			echo "<p align='center'><b>could not upload new photo</b></p><br />\n";
			rename($server_root."employee_photos/".$employee_id.".gif.tmp", $server_root."employee_photos/".$employee_id.".gif");
		}		
	} else {
		echo "<p align='center'><b>could not upload new photo</b></p><p>only jpg files are allowed</p><br />\n";
}

}

END CODE

again... never tested so probably has a bug or 2, but all the none gd stuff works and the files are created just fine, but no thumbnails 🙁

Cheers. I've already got some working though - worked it out about 10 seconds after posting!
The following code takes a file uploaded through a post form with the file field name 'userfile':

########CODE########
$filename=$HTTP_POST_VARS['userfile']['name'];
$size=getimagesize($filename);
$filesize=$HTTP_POST_VARS['userfile']['size']/1000;
$date=date("j F, Y");
$width_denominator=$size[1]/100;
$new_width=$size[0]/$width_denominator;
$split_name=explode(".", $filename);
$thumb_filename=$split_name[0]."_small";
imagecopyresized($thumb_filename, $filename,0,0,0,0,$new_width,100,$size[0],$size[1]);
rename($filename,$server_root."submissions/".$filename.".jpg");
rename($thumb_filename,$server_root."submissions/".$thumb_filename.".jpg");
fwrite($server_root."submissions/pic_inc.txt","<tr><td align=center valign=top><a href=$filename><img src=$thumb_filename border=0></a></td><td align=left valign=top><ul><li>Creator: <a href=mailto:$email>$name</a></li><li>Dimensions: $size[0]x$size[1]</li><li>Date Submitted: $date</li><li>File size: $filesize</ul></td></tr>");
