会话未传递给视图Laravel

Question

I am trying to redirect to a route and pass data and I used with but no go and I also used to just simply set the sessions and then fetch them in the view but no go

Controller code

if($socialUser) {

   Session::put('redirect', 'student-dashboard');
   Session::save();

   return redirect('/register/candidate');
}

View code

<?php if(\Session::get('redirect')) {

        $redirect = session('redirect');
        echo $redirect;
        die();
    } 
?>  

But it never enters this if check and I need data on this view so any advise on this will be helpful.

Please Note :- Session is available in the controller after being sent and I am using Laravel 5.6

Answer 1

Have you tried the code where you then instead set $redirect like you ask the if statement:

$redirect = \Session::get('redirect');

Also if you are using blade templates, you can write the php as;

@php
if (\Session::has('redirect'))
{
    $redirect = \Session::get('redirect');
    echo $redirect;
}
@endphp

The if (Session::has('redirect')) seems to be the proper way to check for whether or not a session exists, according to the Laravel 5.0 documentation, so I'm also leaving that there as a possible change that may help your code work.

I'm not sure u need to use Session::save(); for me its working without it. Try this one.

//controller
if($socialUser) {
   Session::put('redirect', 'student-dashboard');
   return redirect('/register/candidate');
}

//view
@php
    use Session; // or without it just using \Session
    if( Session::has('redirect') ){
      $redirect = Session::get('redirect');
      echo $redirect;
      die();
    }
@endphp

You can also try to use following syntax in controller

 return redirect('/register/candidate')->with('redirect','student-dashboard');

And in view

@php 
   if(session('redirect')){
     //your code here
   }
@endphp

You can't redirect in a view. Redirects have a range of HTTP status codes (3XX). If you've presented a view, then HTTP headers have already been sent (probably with a 200 OK status).

Instead, perform the redirect in your controller:

if ($socialUser) {
    return redirect('student-dashboard');
}

If you need to set the redirect URL in the view for some reason (ie you're passing it to a hidden input) then you'll need to do just that: pass it as a view parameter. Don't try setting it in the session. You won't see any session data set in your controller because the session data is only written after a response has been sent (ie after your view is rendered).
