how to dispaly index method in Laravel 5.2 - php

Question

I am going to view My users table data (username,email) in index.blade.php file. I have UsersController.php like this
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Auth;
use App\User;
use App\Http\Requests;
class UserController extends Controller
{
public function index()
{
$users = User::userr()->get();
return view('users.index')->withUser($users);
}
}
My User Model is
<?php
namespace App;
use Auth;
use Illuminate\Foundation\Auth\User as Authenticatable;
class User extends Authenticatable
{
/**
* The attributes that are mass assignable.
*
* #var array
*/
protected $fillable = [
'username', 'email', 'password',
];
/**
* The attributes that should be hidden for arrays.
*
* #var array
*/
protected $hidden = [
'password', 'remember_token',
];
public function getAvatarUrl()
{
return "http://www.gravatar.com/avatar/" . md5(strtolower(trim($this->email))) . "?d=mm&s=40";
}
public function scopeUserr($query)
{
return $query->where('username',Auth::user()->id);
}
}
and index.blade.php is
#if(isset($user))
#foreach($user as $use)
<h1>{ !! $use->username !! }</h1>
#endforeach
#endif
#endsection
routes is
Route::get('/index', function(){
return view('users.index');
});
but when I visit index view is it display empty page (no error) and did not show name and email
how can fix this prob?

Answer 1

Use User::all(); instead to get all datas from users table rather than User::userr()->get();
Also you have sent variable $users to your view and using $user in #foreach loop of blade.
Change #if(isset($user))
#foreach($user as $use)
to
#if(isset($user))
#foreach($user as $use)
on your blade file.Then it should work.

Answer 2

Check if your route has any action at the index (/). If not, set the route for the index to your desired view or controller. Then, from the controller, return the correct view along with the data you wish to send.
In the blade template, use the exact variable name you passed from the controller.
E.g. ,
Route::get('/', function(){
//variable here
return view('view')->with('var', $var);
});
In your blade,
#if(isset($var))
#foreach($var as $use)
//action here
#endforeach
#endif
Hope this helps.

Update your model and give a propper (meaningful) name to your scope
<?php
namespace App;
use Auth;
use Illuminate\Foundation\Auth\User as Authenticatable;
class User extends Authenticatable
{
/**
* The attributes that are mass assignable.
*
* #var array
*/
protected $fillable = [
'username', 'email', 'password',
];
/**
* The attributes that should be hidden for arrays.
*
* #var array
*/
protected $hidden = [
'password', 'remember_token',
];
public function getAvatarUrl()
{
return "http://www.gravatar.com/avatar/" . md5(strtolower(trim($this->email))) . "?d=mm&s=40";
}
public function scopeUsernameEmail($query)
{
return $query->select('username', 'email');
}
}
Your controller gonna look like something like this
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Auth;
use App\User;
use App\Http\Requests;
class UserController extends Controller
{
public function index()
{
return view('users.index', ['users' => User::query()->usernameEmail()->get()]);
}
}
Then update your routes to use the controller method
Route::get('/index', 'UserController#index')->name('users.index');
And finally in your blade file loop over users like this
<table>
<thead>
<tr>
<td>Username</td>
<td>Email</td>
</tr>
</thead>
<tbody>
#if(isset($users))
#foreach($users as $user)
<tr>
<td>{{ $user->username }}</td>
<td>{{ $user->email }}</td>
</tr>
#endforeach
#endif
<tbody>
<table>
