php – Laravel 4.2验证规则 – 当前密码必须与DB值匹配

目前我有这个：

$rules = array(
    'current_password' => 'required','password'         => 'required|confirmed|min:22'
);

谢谢.

UPDATE

感谢@ChrisForrence和@Ben,我想出了以下内容,效果很好！非常感激.希望这会帮助别人：

Validator::extend('hashmatch',function($attribute,$value,$parameters)
{
    return Hash::check($value,Auth::user()->$parameters[0]);
});
$messages = array(
    'hashmatch' => 'Your current password must match your account password.'
);
$rules = array(
    'current_password' => 'required|hashmatch:password','password'         => 'required|confirmed|min:4|different:current_password'
);

$validation = Validator::make( Input::all(),$rules,$messages );
