Spam Challenger is a TYPO3 CMS extension connected with Formhandler aiming to protect a form from spamming using various technique but without the need of a captcha.

Formhandler is a flexible extension for handling form in TYPO3 CMS. It is a swiss army knife for all kinds of mailforms.

It will basically generate a challenge token stored in the Frontend Session. Upon submitting the challenge will be verified. It may be less efficient than the Captcha technique but will still prevent most spams while keeping the form captcha-free.

• Was a User Session created?
• How fast is the User at submitting the form?
• Honey pot fields

<label index="error_spamchallenger_challenge">Spam challenge did not pass. Hey! Who are you?</label>

When setting debug = 1 at the formhandler level, debug messages will be outputted:

plugin.Tx_Formhandler.settings.predef.foo {

        name = bar

        # Global flag for debugging formhandler
        debug = 1

}
