title: Laravel 5.1 Redirect with variable
body: <p>I am trying to redirect in Laravel like this:</p>
  
  <p>in my controller:</p>
  
  <pre><code>  $state = false;
    return redirect()-&gt;route('newPr')-&gt;with('errorMessageDuration', 'error', $state);
  </code></pre>
  
  <p>and in my view I try to get it like this:</p>
  
  <pre><code>&lt;input id="PrId" type="text" value="{{ isset($state) ? $state : '' }}"&gt;
  </code></pre>
  
  <p>but somehow it does not work, it keeps being empty.</p>
  
  <p>I want it to be saved permanently.</p>
