Roybot06 Posted August 22, 2007 Share Posted August 22, 2007 I am now creating a CAPTCHA image for my site to use in submitting the contact information from the "Contact Us" section. The problem lies in I don't know how to make the PHP allow for the Submit button/function to be hidden until they get the CAPTCHA image correct. I know it would be in the case somewhere, but how would I make the whole page submittable through a function in the PHP is my first problem and the second would be how do I go about hiding this function until the CAPTCHA is solved. Any input would be greatly valued. Quote Link to comment Share on other sites More sharing options...
cooldude832 Posted August 22, 2007 Share Posted August 22, 2007 That would be javascript. Capctcha sets a session = to the code and then the test is if($_POST['code'] == $_SESION['capctcha']) {// Code matches} Basically in javascript modify that using objects and then make a div with the submit button that says if(Match show that div) although this isn't secure because a bot can raddle off a billion tries to get the code right very quickly because it doesn't require a submit to test the values. And the code would be in the source code making it almost pointless. Just use a second page detection. Quote Link to comment Share on other sites More sharing options...
Roybot06 Posted August 22, 2007 Author Share Posted August 22, 2007 I'm still lost to that, they made it a PHP function. As a matter of fact here is the code: <?php require_once('recaptchalib.php'); $publickey = "..."; $privatekey = "..."; # the response from reCAPTCHA $resp = null; # the error code from reCAPTCHA, if any $error = null; # are we submitting the page? if ($_POST["submit"]) { $resp = recaptcha_check_answer ($privatekey, $_SERVER["REMOTE_ADDR"], $_POST["recaptcha_challenge_field"], $_POST["recaptcha_response_field"]); if ($resp->is_valid) { echo "You got it!"; # in a real application, you should send an email, create an account, etc } else { die("Invalid Input, you must be a spam bot.") # set the error code so that we can display it. You could also use # die ("reCAPTCHA failed"), but using the error message is # more user friendly $error = $resp->error; } } echo recaptcha_get_html($publickey, $error); ?> The problem is the submit function on this only works for submitting that form to test the text. So I need to have a global submit function or something like that to send it if they are right, and stop it all together if they aren't. Or something like I stated earlier, have a trigger from them getting this image correct and causing the actual submit button to appear. Thank you, the Javascript idea does make sense though.

cooldude832 Posted August 22, 2007 Share Posted August 22, 2007 I don't know what version of capcthca you are using but this is how I do it form page <html> <img src="captcha/captcha_image.php" alt="security image" border="0"/> Security Code: <input type="text" name="secure"/></br> <input type="submit" value="Register"/> That creates the image off the php doc which also sets sessions then on the processing page <?php session_start(); if($_SESSION['captcha'] != trim($_POST['secure'])){ $error['secruity'] = "The Secruity code does not match the image provided"; } //I create this array called $error which gets filled with arrays and then say if(empty($error)){ //Submit data no errors } else{ echo "<ol>"; foreach($error as $value){ echo "<li>".$value."</li>"; } echo "</ol>"; } ?> Quote Link to comment Share on other sites More sharing options...
Roybot06 Posted August 22, 2007 Author Share Posted August 22, 2007 I am using a program called reCAPTCHA [http://www.recaptcha.com]; it is some university project that is supposed to be the best CAPTCHA out there. I don't understand too much of PHP, I understand what little it reminds me of C; but I am lost as to what I am going to do about this segment of PHP. So is that exactly what you used to make your CAPTCHA? Quote Link to comment Share on other sites More sharing options...
cooldude832 Posted August 22, 2007 Share Posted August 22, 2007 Yup the img src is a php doc that makes the magic code and draws the image, as being good if you are on a help site I think any version is good enough Quote Link to comment Share on other sites More sharing options...
