UPLOAD SCRIPT (MKDIR)

I have a script that i'm writing for an image upload website that will host images and give the user back a URL where they can be linked to at. The URL will be the Image ID in the Database. Here is my script:

<?php      
                  require("db_fns.php");
                  // 1. Get largest ID from DB.

                  db_connect();
                  $sql      =      "SELECT * FROM FILE_UPLOADS ORDER BY ID DESC LIMIT 1";
                  $result      =      mysql_query($sql);
                  $DirNum =      mysql_fetch_assoc($result);                  

                  // 2. Increment the ID returned by 1 and save into variable $DirID.
                  $CurrentID = $DirNum['ID'];
                  $DirID      =      $CurrentID + 1;
                  
                  // 3. On the file share, MkDir with the name contained in $DirID.
                  
                  $oldmask = umask(0);
                  mkdir ("/" . $DirID);
                  umask ($oldmask);
                  
                  // 4. Upload the file to the new $DirID directory.
                  
                  $filename = $HTTP_POST_FILES['userfile']['name'];
                  if ( $userfile == "none" )
                  {
                        echo "Problem: No file uploaded";
                        exit;
                  }
                  
                  if ( $userfile_size == 0 )
                  {
                        echo "Problem: Uploaded File is Zero Length";
                        exit;
                  }
                  
                  if ( $userfile_type != "image/gif" || $userfile_type != "image/jpg" )
                  {
                        echo "Problem: File is not a valid JPG or GIF file";
                        exit;
                  }
                  if ( !is_uploaded_file($userfile) )
                  {
                        echo "Problem: File already exists in this directory.";
                        exit;
                  }

                  $tempfile = $HTTP_POST_FILES['userfile']['tmp_name'];
                  $destination = $DirID . "/" . $HTTP_POST_FILES['userfile']['name'];
                  
                  if ( !copy($tempfile, $destination))
                  {
                        echo "Problem: Could not move file into this directory";
                        exit;
                  }
                  
                  
                  // 5. Save this new index.php file into the new $DirID directory.
                  $original      =      "/templates/index.php";
                  $new            =      "/" . $DirID . "/index.php";
                  copy ($original, $new);                  
                  
                  // 6. Create and write a new file named "index.php" in the $DirID folder that displays the uploaded file from userfile.
                  
                  $fp      =      "/" . $DirID . "/index.php";
                  $descriptor            =      fopen ($fp, "w+");
                  
                  $image                  =      $HTTP_POST_FILES['userfile']['name'];
                  
                  $content            =      do_index_output($DirID, $image);
                  fwrite($fp, $content);
                  
                  // 7. Build the URL and store the URL and ID # in the DB.
                  
                  $filename      =      $HTTP_POST_FILES['userfile']['name'];                  
                  $url            =      "http://www.diverse-networks.com/" . $DirID;
                  
                  $sql2            =      "INSERT into FILE_UPLOADS ('ID', 'url', 'filename') VALUES('$DirID', '$url', '$filename')";
                  $result            =      mysql_query($sql2);
                  
                  // 8. Return URL to screen for user to log.
                  
                  if(!result)
                  {
                        echo "Problem with storing new Image in the Database.";
                  }
                  else
                  {
                        echo "Your image was uploaded successfully and can be found at: " . $url;
                  }
?>


When I click the upload button on the form, I get this error message:

Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource in /home/diverse/public_html/friz/upload.php on line 8

Warning: mkdir(): open_basedir restriction in effect. File(/1) is not within the allowed path(s): (/home/diverse:/usr/lib/php:/usr/local/lib/php:/tmp) in /home/diverse/public_html/friz/upload.php on line 17
Problem: Uploaded File is Zero Length

WHAT IS IT THAT I'M DOING WRONG?

Thanks,
