RedDot UI: Check Filename

Here is yet another user interface extension for you: Assigning file names in RedDot can be a bit tricky – if you choose the same name twice and both pages are published to the same directory, one file overwrites the other (depending on which file gets published first). This extension allows you to check for duplicate file names.

The setup is quite easy:

  1. Install the extension and put its link into your masterpages (documentation is included in the archive)
  2. Assign a filename to your current page
  3. Click the “Check Filename” link to see if the name has already be taken.

That’s all, folks!


With Version 1.1, there are two different operation modes: A HTML popup (default) and a direct text output for AJAX calls. Additionally, you can also check if the given file name is valid (contains only chars, numbers, hyphens, underscores and periods) – no spaces, umlauts or other characters a web server might have problems with.


Latest version can be downloaded/forked at GitHub

  2. Hi – just downloaded this plugin, but there is no xml definition file included. How do I install it?

  3. Why don’t you take a look at the included README.txt? ;)

  5. Is there any possibility of this plugin being updated to work with v10? We’ve become quite reliant on it but v10 seems to have changed how the values it uses are specified.

  6. The RQL part of this plugin is quite simple, so this shouldn’t be the problem.
    So you just have to ask OT for an update of the RQL documentation (or go through the release notes of the v10 builds) to figure out what has changed.
