Contact Form 7 Image Captcha

Description

Add an SVG image captcha and honeypot to your contact form 7 form. This CAPTCHA is GDPR compliant and becuase the images are inline SVG’s, this plugin will not slow down your site with additional header requests like Google’s ReCAPTCHA.

Directions [PLEASE READ]

Add the shortcode [cf7ic] to the form editor where you want the captcha to appear.

You can hide the CAPTCHA until a user interacts with the form, by adding “toggle” to the shortcode.
[cf7ic “toggle”]

FAQ

How do you add the image CAPTCHA to the forms?

Simply add this shortcode [cf7ic] to your contact form

How do you use the toggle feature?

To make it so the CAPTCHA only shows when the form is being filled out, add “toggle” to the shortcode [cf7ic "toggle"] in your contact form.

Toggle is not working

The most likely reason the toggle is not working is because the double quotes around the word toggle has been changed to “smart quotes”, meaning that they are opening and closing quotation marks and not the verticle lines.

To fix, simply delete the quotes and re-add them with your keyboard – do not copy and paste.

Why does the image CAPTCHA not appear?

If the Image CAPTCHA does not appear, please confirm that you are running PHP version 7 or higher.

Why does the styling of the image CAPTCHA look wrong?

If the styling does not look right, you may need to clear your browser cache. If you have any caching plugins or speed optimization plugins installed, you may need to clear your site cache as well.

I found a small bug in this with the http hard links. Developer not only responded in a friendly manner, but had this thing fixed and published to the world within something like 2 hours of me reporting it. Shockingly good. And of course, the plugin works flawlessly in every way imaginable. 6/5 stars from me. We need more developers with this kind of work ethic.

Totally like how user friendly and effective the icon quiz is designed. I can also recommend the pro version which offers more options and features to make it a perfect fit for your website. Great service on top of that, thank you for your quick reply on my request.

After a deluge of spam recently, I almost had to settle for Google ReCaptcha. But the ReCaptcha scripts are not efficient. The image captcha is a perfect solution to the spam problem, being easy and fast to use.
