I will post the code for the form and recaptcha not the mess i have been making. <?php // php for recaptcharequire_once('recaptchalib.php'); // reCAPTCHA Library$pubkey = ""; // Public API Key$privkey = ""; // Private API Key if ($_POST['doVerify']) { $verify = recaptcha_check_answer($privkey, $_SERVER['REMOTE_ADDR'], $_POST['recaptcha_challenge_field'], $_POST['recaptcha_response_field']); if ($verify->is_valid) { # Enter Success Code echo "Your response was correct!"; } else { # Enter Failure Code echo "You did not enter the correct words.

you want to chek dynamically captcha first then submit the form. right? you need to use ajax to submit the captcha to php page which will validate the capctha if it matches you can then send the rest of the data of the form. unless you want to do it dynamically you can send all the data with captcha in php page and process it there.

What would be the best why of doing this with ajax or posting the whole form? With ajax will it hold the details of the for until the recaptcha has been validated, and also with ajax will i need a new PHP file to hold the recaptcha PHP verify file.Thank you.

both will work same as functionalty. with ajax it will increase user experiance.ajax is also javascript which makes request to php file and get response from it.there you can start http://w3schools.com/ajax
