hCaptcha integration | WordPress.org

Maybe try this?

<?php echo do_shortcode( '[hcaptcha auto="true"]' ); ?>

Thanks for your hint. The result is the same as before. The captcha is not a mandatory field…

Here is, how I solved the problem.

Add hCaptcha to the booking form:

<?php echo do_shortcode( '[hcaptcha]' ); ?>

Add validation into function.php:

function em_validate($result, $EM_Event){ 
	$captcha_result = null;
	
	$captcha_result = hcaptcha_verify_post();
	
	if ( null !== $captcha_result ) {
		$EM_Event->add_error('Bitte löse das Captcha-Rätsel.');
		$result = false;
	}

	if (!is_user_logged_in() && $_REQUEST['user_name'] == ''){
		$EM_Event->add_error('Bitte gib deinen Namen an.');
		$result = false;
	}
		
	if (!is_user_logged_in() && $_REQUEST['user_email'] == ''){
		$EM_Event->add_error('Bitte gib deine E-Mailadresse an.');
		$result = false;
	}	
	
	return $result;	
}
add_filter('em_booking_validate','em_validate', 1, 2);

I hope, this will help others to protect the booking form against spam submissions.

Have fun!
