In the search for a contact form for Dokuwiki I only found that of Bob Baddeley. It is quite good, although a bit outdated. You can find this plugin on Github.

It is nearly the same form like that by Bob Baddeley, except:

1. reCaptcha instead of „Enter HUMAN to verify.“
2. Captcha can be disabled.
3. Improved configuration.
4. Improved anti cache work-around.
5. Intelligent email address checkup.
6. No annoying JavaScript-alerts.
7. It jumps back to the form after submitting.
8. Name and email field are filled if user is logged in.

If you have some more ideas, feel free to contact me.

Following languages are available: German, English, Russian (partially), Portuguese (partially), French (partially)

To use this Plugin you need the following system:

• PHP >= 5.1.2
• Dokuwiki >= 2009-02-14b
• reCaptcha keys (optional)

You can receive the needed reCaptcha keys on google.com/recaptcha.

To install this plugin go to Admin → Manage plugins and enter in the following url:

http://downloads.echtzeitraum.de/plugin/dokuwiki/contactmodern.zip

In Admin → Configuration settings you have to set up a valid email address and (if you want) your reCaptcha keys. You can modify and redistribute it under the terms of the GPL Version 3.

The integration is the same as in the plugin by Baddeley. Simply enter this code:

{{contact>}}

This will create a contact form with a „name“,“email address“, „subject“ and „comment“ field. It will send an email to whatever the default value is. If you enabled the captcha by default, than it will also show the well known reCaptcha input fields.

You can also specify several parameters. If you only need one parameter you simply use:

{{contact>subj=Feedback from Site}}

or join multiple of them with a | character:

{{contact>to=profile1|subj=Feedback from Site}}

Available parameters:

Or look at it in the wild .

• Only one contact form per page accepts reCaptcha.
