reCAPTCHA helper and validation function (easy-to-use captcha) |
[eluser]vendiddy[/eluser]
This is a widely used captcha implementation. It's used at big sites like Facebook and CraigsList. Steps to Use 1. Sign up for an access key at http://recaptcha.net/ 2. Get recaptchalib.php from the zip archive located at http://code.google.com/p/recaptcha/downl...lib-Latest. 3. Rename recaptchalib.php to recaptcha_helper.php and put it in your helpers folder. 4. Add the following function to recaptcha_helper.php: Code: function recaptcha() 4. Add the following function to your MY_Validation class as seen below in the libraries folder. (If you don't already have one a MY_Validation class, make one.) Code: <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed'); 5. Create a recaptcha.php in your config folder and add your public and private keys (the ones you got from registering) as seen below: Code: <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed'); Example usage in a controller: Code: public function register() In the view, you can create the captcha form element by echoing <?= recaptcha() ?> I can package all of this into a zip file upon request.

Try to make sure your domain name matches and that you entered in your public / private keys in correctly into the config file.

Hi PermanaJ, I wrote this helper for version 1.6 of CI. The current version of CI is now 1.7 which uses form_validation instead of validation. Someone else modified it to work with version 1.7 and posted it here: http://ellislab.com/forums/viewthread/96365/ Good luck!

Ohh .. im using 1.7 .. thank a lot for the information ... but the code above work well with 1.7

Hi, I am not a website admin, I am just trying to post a comment into a site that uses Capcha. The Capcha works for everyone else, i.e. they can see an image and a field to enter what they see and are able to click sumbit, but not for me. Instead, I get the same message "This reCAPTCHA key isn't authorized for the given domain. More info" I read the replies but don't understand the cause of the problem, as I'm not very capcha savvy.. can anyone help? thank you

I've made changes to make this work in CI 1.7.x First, rename MY_Validation.php to MY_Form_validation.php then change the code to match this: Code: <?php and thats it. Your recapture should now work with the current form validation class. |
