CAPTCHA control for handling form SPAM

captcha
Recently I used a free utility reCAPTCHA in my website contact form. The commonly accepted approach of handling form SPAM is by using a CAPTCHA control on your forms. reCAPTCHA helps prevent automated abuse of your site
Below are step-by-step instructions for integrating reCAPTCHA in your CI app.
  • Create a reCAPTCHA account
  • Download the reCAPTCHA PHP library
  • Use the library in your project
To change the theme and other options, simply create a dictionary called RecaptchaOptions in a script-tag:


Choose captcha format: Image or Audio
Absolutely, the reCAPTCHA website has detailed instructions for how to alter the look and feel of the reCAPTCHA form control.
