I’m using Symfony2 and the FOSUserBundle to manage registration and logins. I’d like to add a captcha system. Is there are pre-existing bundle or tutorial on this?
Of course, I could try to roll my own using Google re-captcha. In that case, is Google reCaptcha a good choice, or should I use some other API?
There are indeed a bundles for that, take a look at:
CaptchaBundle
Or
EWZRecaptchaBundle
Both got (most likely) all the documentation you need added in the README.md file or extended documentation.
