Laravel身份验证检查

Question

My navbar should display the Sign up and Login buttons only if the user is not authenticated, otherwise a Log out button.

                @if(Auth::check())
                    <li><a class="navbarButton"  href="auth/register"><span class="glyphicon glyphicon-user"></span> Sign Up</a></li>
                    <li><a class="navbarButton" href="auth/login"><span class="glyphicon glyphicon-log-in"></span> Login</a> </li>
                @else
                    <li><a class="navbarButton"  href="auth/logout"><span class="glyphicon glyphicon-log-out"></span> Log out</a></li>
                @endif

I know that the user is authenticated, because I get redirected from the login and register pages, but they are still showing in the navbar.

It seems that you have got your logic the wrong way around here:

@if(Auth::check())
  //this will show if the statement is true (user logged in)
  <li><a class="navbarButton"  href="auth/register"><span class="glyphicon glyphicon-user"></span> Sign Up</a></li>
  <li><a class="navbarButton" href="auth/login"><span class="glyphicon glyphicon-log-in"></span> Login</a> </li>
@else
  //this will show if the statement is false (no user logged in)
  <li><a class="navbarButton"  href="auth/logout"><span class="glyphicon glyphicon-log-out"></span> Log out</a></li>
@endif

If you reverse it to:

@if(Auth::check())
  //this will show if the statement is true (user logged in)      
  <li><a class="navbarButton"  href="auth/logout"><span class="glyphicon glyphicon-log-out"></span> Log out</a></li>
@else
  //this will show if the statement is false (no user logged in)
  <li><a class="navbarButton"  href="auth/register"><span class="glyphicon glyphicon-user"></span> Sign Up</a></li>
  <li><a class="navbarButton" href="auth/login"><span class="glyphicon glyphicon-log-in"></span> Login</a> </li>
@endif
