Contact Form with reCAPTCHA

“Contact Form 7 reCAPTCHA Extension” is a WordPress-Plugin, that connects Contact Form 7 and WP-reCAPTCHA. This provides an additional opportunity to protect your forms from unwanted spam.

Our sites are not the only ones in the world who use WordPress as a platform. Many thousands, if not millions of others use it as well. To offer opportunities to interact frequently with the users of the site forms are used.

A fairly wide range of plugin for this purpose is Contact Form 7. It makes it possible to create forms in a simple manner and bind them to sites or articles. This extension can be embedded in your WordPress instance via the built in WordPress Plugin Manager (Administration page -> Plugins -> Install) or it can be downloaded at the following link:

A major problem in such forms is spam. Messages that are usually written automatically in such a form to serve some ominous advertising purposes only. To protect against such unwanted messages, there are various techniques available. These include the so-called CAPTCHAs. These generated and only human-readable images prevent your form to be automatically read by computers and thus beeing used to send you those unwanted messages.

The Contact Form 7 plugin has its own very simple CAPTCHA. This, in our opinion, does not offer much protection. An also widespread WordPress extension that can turn off this deficiency is WP-reCAPTCHA. This extension can also be installed using the Plugin Manager or can be downloaded from the following page:

The developer of Contact Form 7 had been provided a “module” for integration of WP-reCAPTCHA in forms. But it is not available anymore. Based on that module we have written a plugin for WordPress which provides the capabilities of WP-reCAPTCHA in Contact Form 7.

A problem with this module was that in case of an update of Contact Form 7 you had to copy it over again by hand into the “modules” directory of the plugin. With a real plugin for WordPress this is no longer necessary.

Our plugin is of course available via the Plugin Manager if you search for its name “Contact Form 7 reCAPTCHA Extension” or you can download it from the following page:

If there are questions you are welcome to use the WordPress forums offered at the following address:

We hope that this plugin may limit the amount of spam in your WordPress installation further.
