Add an SVG image captcha and honeypot to your Contact Form 7 or WPForms form. Based on our interpretation this CAPTCHA plugin is GDPR compliant because the images are inline SVGs and no download of external resources happens, in addition no cookies or other storing mechanisms are used on the user’s device, this plugin will not slow down your site with additional header requests like Google’s ReCAPTCHA and respects your users privacy.
<h4>Directions [PLEASE READ]</h4>
Contact Form 7: 
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”]
WPForms: 
Just activate the CAPTCHA for WPForms on the plugin’s settings page.

Image CAPTCHA for Contact Form 7 and WPForms by HookAndHook (DSGVO/GDPR)

All good, but today I've added some WPBakery Tabs block with buttons and have a lot of errors about not existing contact form when click the tab buttons. So I've fixed your script to enable captcha on form focus, now it really works only at CF7. Please replace your existing CF7 script function to my one:



function cf7ic_toggle()
{
 echo '<script type="text/javascript">
 document.addEventListener("focusin", cf7ic_display);

 function cf7ic_display(event){
 if(event.target.form && event.target.form.querySelector(".cf7ic-toggle")) {
 event.target.form.querySelector(".captcha-image").style.display = "block";
 }
 }

 document.addEventListener( "wpcf7mailsent", function( event ) {
 if (event.target.querySelector(".captcha-image")) {
 event.target.querySelector(".captcha-image").style.display = "none";
 document.activeElement.blur();
 }
 }, false );
 </script>';
}

JS needs to be fixed


Love the Plugin in its simplicity. The support is lightning fast!







Thanks So much


Great Support and Great Plugin
