Description
A CAPTCHA is the standard solution for protecting your forms from robot generated SPAM. This SPAM could mean fake users, countless advertising comments or generally unwanted data filled into your wiki. For more solutions on fighting SPAM in your wiki, see the AntiSpam Guide.
The CAPTCHA Application offers an Administration UI for selecting the default CAPTCHA implementation that your wiki is using.
The currently known implementations are:
- JCaptcha (offline, bundled with the XWiki Standard Flavor)
- Google's reCAPTCHA service (online, installable as an extension)
Once the CAPTCHA implementation is selected, the configuration options (if any) of that implementation are displayed, together with a preview of how the configured CAPTCHA will look like to your users.
Note that this selection only applies to forms in your wiki (standard forms, application forms, custom forms, etc.) that are using the CAPTCHA API. Any custom implementation of a CAPTCHA solution that either does not use the API or uses a fixed CAPTCHA every time will not be affected by a change in this configuration.
See the CAPTCHA API to find our how to easily add a CAPTCHA to your form.
Prerequisites & Installation Instructions
We recommend using the Extension Manager to install this extension (Make sure that the text "Installable with the Extension Manager" is displayed at the top right location on this page to know if this extension can be installed with the Extension Manager). Note that installing Extensions when being offline is currently not supported and you'd need to use some complex manual method.
You can also use the following manual method, which is useful if this extension cannot be installed with the Extension Manager or if you're using an old version of XWiki that doesn't have the Extension Manager:
- Log in the wiki with a user having Administration rights
- Go to the Administration page and select the Import category
- Follow the on-screen instructions to upload the downloaded XAR
- Click on the uploaded XAR and follow the instructions
- You'll also need to install all dependent Extensions that are not already installed in your wiki
