How I can access data property from MySQL in Controller - php

Question

I learning about laravel framework, I don't know how to access property in my controller.
public function uuid(Request $request)
{
if($request->get('uuid') == null) return abort(404);
$uuid = $request->get('uuid');
$users = DB::table('users')->select('*')->where('uuid', $uuid)->get();
$result = array([
'id' => $users['id'],
'username' => $users['username'],
'uuid' => $users['uuid'],
]);
return view ('dashboard')->with('username', $result['username']);
}
in my dashboard.blade.php
{{$username}}
When i come to dashboard it show error like this
ErrorException (E_NOTICE)
Undefined index: username

Answer 1

Use First() instead of get() you'll get object so access data like.
$users = DB::table('users')->select('*')->where('uuid', $uuid)->first();
$result = array([
'id' => $users->id,
'username' => $users->username,
'uuid' => $users->uuid,
]);
return view ('dashboard')->with('username', $result['username']);
Now sort way to do it.
$user = DB::table('users')->select('*')->where('uuid', $uuid)->first();
$username = '';
if(!empty($user)){
$username = $user->username
}
return view ('dashboard',compact('username'));

Answer 2

$users is a collection of users. So you cannot access a property of a user like $users['id'];
If you want to get one user object from the database, you need to call first() instead of get()
Possible Solution
$user = DB::table('users')->select('*')->where('uuid', $uuid)->first();

Answer 3

You can use firstOrFail();
$users = DB::table('users')->select('*')->where('uuid', $uuid)->firstOrFail();
$result = array([
'id' => $users->id,
'username' => $users->username,
'uuid' => $users->uuid,
]);
return view ('dashboard')->with('username', compact('username'));

Answer 4

A possible short version of your solution may be like following
public function uuid(Request $request)
{
$user = User::select('username')->where('uuid', $request->uuid)->firstOrFail();
return view ('dashboard')->with('username', $user->username);
}
