如何在Laravel中验证失败的验证值

Question

I'm trying to pass a value on failed validation in Laravel.

I tried this, but couldn't get the output.

if ($validation->fails()) {
   $errorflag=1;
   return Redirect::back()->withInput()->withErrors($validation)->with('errorflag', $errorflag);
}

I tried to get this value in the view using just a isset() check

<?php 
  if(isset($errorflag)){
      echo $errorflag;
  }
?>

But I'm unable to get the output even though I made a validation error in the form. How can I do this?

No need for a flag or session param, withErrors fills the variable $errors and thus is detectable:

@if($errors->any())
   // do something
@endif
