Codeigniter Login Attempts Throttle

##Background I was looking for a Codeigniter login throttling library and couldn't find a simple one to use, so I wrote one.

##How it works

• first clean up old logins
• Count matching IP address and type (optional, useful if more than one throttle type. IE: logins, submissions)
• Compare to limit
  • If over limit, show error 503
  • if not over, return number of attempts

##Usage ###install

put files into proper codeigniter directories

• MY_Model [https://github.com/avenirer/CodeIgniter-MY_Model](download from here. The file in the folder will not work.)
• Throttle_model
• Throttle library in correct locations (see file structure above)

###initialize in your controller __construct() or in a function, call

$this->load->library('throttle');

###Use

$attempts = $this->throttle(1); //run throttle check from throttle library, type 1

or

$attempts = $this->throttle(5, 5, 60); //run throttle check from throttle library, type 5, limit 5 attempts every hour

##Requirements CodeIgniter 2 or 3 MySQL database or equivalent MY_Model from avenirer (find it on github. It's great.) or equivalent

database table called throttles with the following:

CREATE TABLE throttles
(
  id INT UNSIGNED PRIMARY KEY,
  ip VARCHAR(64),
  created_at DATETIME,
  updated_at DATETIME,
  type INT UNSIGNED
);
