Hi,
a while ago I made some extensions to the captcha plugin. Maybe it will
be considered useful. The changes are:
- Make the honeypot invisible or not. It doesn't disable the honeypot.
Configurable.
- Show the text "Please fill ..." between the image and the input field.
Configurable.
- Limit the length of the input field of the captcha code. The limit is
the same as 'lettercount' - works but is not perfect. The limit should
be somehow greater than 'lettercount', but not unlimited. Not
Configurable (yet).
I did made a pull request, but a patch is available too:
patchfile: http://ftp.dyndn.es/dokuwiki/captcha-patch-latest.tgz
(version 20170206)
md5sum: http://ftp.dyndn.es/dokuwiki/captcha-patch-latest.md5
Feel free to use it or parts of it. A README is included in the patch,
as well a css file for extended formatting..
Another idea I have realized in a test environment is to make the
'lettercount' flexible inside a definable range. Means, if the
'lettercount' config value is 6, than it will randomly increased to 7 or
8 (depending on the range value) - or maybe not. For those who don't
know: 'lettercount' is the number of letters used by the captcha image.
Would this makes sense?
regards
Kai
