since $code isn't defined in function or handed parameter, doesn't exist. hence 'undefined variable' error getting.

if send $code view, , want $code when view posts form, add value of $code form-element , read input::get().

view:

  <!-- inside form -->   <input type="hidden" name="code" value="{{ $code }}" /> 

model/controller:

$code = input::get('code'); 

alternatively, create session containing $code , read value once method postresetpassword() called.
