UploadPlus : File Name Cleaner


NEW: EXIF header malware/backdoor sanitization!

Filenames on the web are different than those on the desktop. Empty spaces and strange characters doesn’t belong to web space. Enter UploadPlus: you can set your rules and clean your files’ name while they upload. Three basic rules:

  • keep only alphanumeric [A-Za-z] and digits, spaces and strange characters stripped out;
  • convert spaces and strange characters into dashes (-)
  • convert spaces and strange characters in underscores (_)

You can apply website-based or date-based prefix, even a custom prefix. Lowercase or Uppercase? Your choice!
Some default prefix:

  • time/date based timestamps via PHP date()
  • blog name/slug
  • random
  • and many more!

UploadPlus can also transliterate filenames (text conversion from a non-latin script to raw latin characters).
You can preview settings in the media settings page without uploading files.


We’ll do our best to support the plugin on support forum. Paid support and custom coding options are available on the SWERgroup HelpDesk.

If you found this plugin useful or need a new feature feel free to sponsor a coding/support session!
