Honeypot Module for Contact Form 7 WordPress Plugin

This simple addition to the wonderful Contact Form 7 (CF7) plugin adds basic honeypot anti-spam functionality to thwart spambots without the need for an ugly captcha.

The principle of a honeypot is simple — bots are stupid. While some spam is hand-delivered, the vast majority is submitted by bots scripted in a specific (wide-scope) way to submit spam to the largest number of form types. In this way they somewhat blindly fill in fields, irregardless of whether the field should be filled in or not. This is how a honeypot catches the bot — it introduces an additional field in the form that if filled out will cause the form not to validate.

Installation

  • Install using the WordPress “Add Plugin” feature — just search for “Contact Form 7 Honeypot”.
  • Confirm that Contact Form 7 is installed and activated. Then activate this plugin.
  • Edit a form in Contact Form 7
  • Choose “Honeypot” from the CF7 tag generator. Recommended: change the honeypot element’s ID.
  • Insert the generated tag anywhere in your form. The added field uses inline CSS styles to hide the field from your visitors.

The fine folks at RoseApple Media put the above video together detailing the simple process of getting up and running with CF7 Honeypot. NOTE: This video was not produced by the CF7 Honeypot developer.

Altering the Honeypot Output HTML [ADVANCED]

While the basic settings should keep most people happy, we’ve added several filters for you to further customize the honeypot field. The three filters available are:

  • wpcf7_honeypot_accessibility_message – Adjusts the default text for the (hidden) accessibility message.
  • wpcf7_honeypot_container_css – Adjusts the CSS that is applied to the honeypot container to keep it hidden from view.
  • wpcf7_honeypot_html_output – Adjusts the entire HTML output of the honeypot element.

For examples of the above, please see this recipe Gist.

Frequently Asked Questions

Will this module stop all my contact form spam?
Probably not. But it should reduce it to a level whereby you don’t require any additional spam challenges (CAPTCHA, math questions, etc.).

Are honeypots better than CAPTCHAs?
This largely depends on the quality of the CAPTCHA. Unfortunately the more difficult a CAPTCHA is to break, the more unfriendly it is to the end user. This honeypot module was created because we don’t like CAPTCHA’s cluttering up our forms. Our recommendation is to try this module first, and if you find that it doesn’t stop enough spam, then employ more challenging anti-spam techniques.

Can I modify the HTML this plugin outputs?
Yep! See the Installation section for more details and this gist for examples.

What is the plugin license?
This plugin is released under a GPL license.
