Download this package and uncompress it within application/ directory of your CodeIgniter site. Then activate Session library/driver. GD image processing PHP module should be installed.

This feature has been tested on CodeIgniter 3.1.11 (September 19th, 2019).

A Quick Test

Open with browser the following URL:

http://localhost/site/index.php/captcha_test

http://localhost/site/captcha_test (if you removed the URL-segment index.php).

Usage

Examine code of the controller Captcha_test.php and the views captcha_test.php and captcha_test_ok.php. This would be enough for you to get the idea how captcha feature works.
