Use input from one view to print result into another view - php

Question

I want to use input from a form in one view and print results into another view. I get the following error: Undefined variable: users Thanks in advance!
The form (in a view called 'dashboard') that I am using to get email address:
...
<div class="search">
<header><h3>Search Friend</h3></header>
<form action="{{ route('search.friend') }}" method="post">
<div class="form-group">
<input class="form-control" type="text" name="email" id="email" placeholder="Friend's email">
</div>
<button type="submit" class="btn btn-primary">Post</button>
<input type="hidden" value="{{ Session::token() }}" name="_token">
</form>
</div>
...
The route to send data from 'dashboard' to Controller:
Route::post('/searchfriend',[
'uses' => 'FriendController#getSearchFriend',
'as' => 'search.friend',
'middleware' => 'auth'
]);
The controller where I use the email to find user:
class FriendController extends Controller
{
public function getSearchFriend(Request $request)
{
$this->validate($request,[
'email' => 'required | email'
]);
$email = $request['email'];
$users = User::where('email',$email)->get();
return view('userlist',['$users' => $users]);
}
}
The route to send the result to a 'userlist' view:
Route::get('/userlist',[
'uses' => 'FriendController#getSearchFriend',
'as' => 'userlist',
'middleware' => 'auth'
]);
Finally, the 'userlist' view:
#extends('layouts.master')
#section('title')
Users
#endsection
#section('content')
<section class="row new-post">
<div class="col-md-6 col-md-offset-3">
<header><h3>Users</h3></header>
<div class="userlist">
<header><h2>Click to Add Friend</h2></header>
#foreach($users as $user)
Name: {{ $user->username }}
#endforeach
</div>
</div>
</section>
#endsection

Answer 1

Change:
class FriendController extends Controller
{
public function getSearchFriend(Request $request)
{
$this->validate($request,[
'email' => 'required | email'
]);
$email = $request['email'];
$users = User::where('email',$email)->get();
return view('userlist',['$users' => $users]);
}
}
to:
class FriendController extends Controller
{
public function getSearchFriend(Request $request)
{
$this->validate($request,[
'email' => 'required | email'
]);
$email = $request['email'];
$users = User::where('email',$email)->get();
return view('userlist',['users' => $users]);
}
}
You don't need the $ when passing the name of the variable to the view.

Answer 2

#Ryan J Field is correct. Also, you can pass the variable in many different ways. Such as -
return view('userlist')->with('users', $users);
Or,
return view('userlist', compact(users));
