    Hi,
    I’m trying to integrate captcha into Jetpack contact form. I can use the jetpack_contact_form_is_spam filter to mark the form submission as spam if the user fails to solve the captcha. The problem is that the user is not aware of failing to solve the captcha. Is there a better hook where I can check if the captcha is correct and alert the user in case it isn’t?

    Thanks,
    Guy

  • Hi Guy,

    When the captcha validation fails, you can return a WP_Error on the jetpack_contact_form_is_spam filter to abort the process submission and modify the contact form HTML. Example:

    add_filter( 'jetpack_contact_form_is_spam', function ( $is_spam, $submission ) {
    	$is_captcha_valid = false; // Replace by calling your custom validation.

    	if ( ! $is_captcha_valid ) {
    		// My custom error.
    		$error = new \WP_Error( 'captcha_failed', __( 'CAPTCHA verification failed. Please try again.') );

    		// Modify the contact form HTML.
    		add_filter( 'jetpack_contact_form_html', function ( $format_html) use ( $error ) {
    			return '<pre>' . $error->get_error_message() . '</pre>' . $format_html;
    		} );

    		// Return a custom error to abort the form process submission.
    		return $error;
    	}

    	return false;
    }, 10, 2 );

    Please let me know if it works.
