not recognizing error messages specified for a custom validation in laravel 4.2 -

i made custom validation in laravel 4.2 , put in app/start/global.php , code there this

validator::extend('captcha', function($attribute, $value, $parameters) {  $captcha = $_session["captcha"];  return $value == $captcha; });  validator::extend('csy', function($attribute, $value, $parameters) {  $appnd = "sy " . $value ."-". ($value + 1);  $chksy = db::table('dbo_schoolyear')           ->where('schoolyear' , '=' , $appnd)           ->count();  if($chksy)  {     return false;  }  else  {     return true;  }  }); 

then in controller here code

$rules = array(         'nsy' => 'required|integer|min:2005|csy'     );        $messages = array(         'nsy.required'  => 'please enter starting year.',         'nsy.integer'   => 'starting year can contain integer values',         'nsy.min'       => 'school year minimum 2005',         'nsy.csy'       => 'school year exists'     ); 

the validation works message declared in messages array not being recognized. dont know why. error outputs validation.c_sy ideas on doing wrong?

it's camelcase issue: csy being interpreted c_sy.

simply change csy csy.
