After many different attempts I was finally able to add a working captcha to my bootstrap contact form. I ended up using SecureImage from phpcaptcha.org. It seems to be working fine - it sends the email if the captcha is entered correctly and it does NOT send the email if the captcha is entered incorrectly. However, I cannot get it to display an error message if the incorrect captcha is entered. Instead, it still displays a message saying the email was sent successfully, when in reality it is not. My contact form uses a contact_me.js file with an ajax function to validate and send the form content to a contact_me.php file for processing. The form is validated using jqBoostrapValidation.js in combination with the contact_me.js.
How can I get it to post an error message on the html page (as it does with the other field validations) if the incorrect captcha is entered. I am new to PHP and JS/Ajax and the contact form I am using is a template supplied by startBootstrap.com. I assume I need some kind of callback function to bring the captcha failure result from the PHP back to the contact_me.js file to display the error - but I don't know how to do this. Any help would be greatly appreciated.
