Anti spam honey pot

It has been a while, but I have recently come a cross an issue with the honey pot.

I never created an expire time for the token.

Update the ./config/config.php file and add

PHP Code:

$config['honey_pot_expire'] = 3600; 


Update the ./core/MY_Security.php file and add the following lines

PHP Code:

protected $_honey_pot_expire; // The time the token remains valid for. Default is 1 hour
...
...

public function __construct() {
   ...
   ...
   $this->_honey_pot_expire = config_item('honey_pot_expire');
}

/**
 * Honey pot Set Cookie
 *
 * @return CI_Security
 */
public function honey_pot_set_cookie() {
 
    $expire = time() + $this->_honey_pot_expire;
    ...
    ...
} 


The code provided in the OP has also been updated
