When I'm trying to pass an object through a view with the AppServiceProvider it gives an error an says
Trying to get property of non-object
This is currently my App\Providers:
<?php
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
use App\User;
use Auth;
class AppServiceProvider extends ServiceProvider
{
/**
* Bootstrap any application services.
*
* #return void
*/
public function boot()
{
$users = Auth::user();
view()->share('user','users');
}
/**
* Register any application services.
*
* #return void
*/
public function register()
{
//
}
}
And when I say in the view:
{!! user->name !!}
It throws an error.
you are missing the '$' on users when passing the variable to view. So it can't be rendered on the view.
it must be:
$users = Auth::user();
view()->share('user', $users);

I'm new at Laravel, and I'm trying to make Policies that will prevent user that doesn't have id_level 1 which is admin to access InventarisController, but the InventarisPolicy doesn't send variable to InventarisController.
it's my Inventaris Policies
InventarisPolicy.php
<?php
namespace App\Policies;
use App\{User, Level};
use Illuminate\Auth\Access\HandlesAuthorization;
class InventarisPolicy
{
use HandlesAuthorization;
/**
* Create a new policy instance.
*
* #return void
*/
public function __construct()
{
//
}
public function inventaris_add(User $user)
{
$user->id_level == 1;
// dd($user);
// $user->id_level == 2;
}
}
it's my Inventaris Controller
InventarisController.php
<?php
namespace App\Http\Controllers;
use App\{Inventaris, DetailPinjamanView};
// use Illuminate\Http\Controllers\Auth;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\Facades\Auth;
// use App\Http\Controllers\Auth\Request;
use Illuminate\Foundation\Auth\AuthenticatesUsers;
class InventarisController extends Controller
{
/**
* Create a new controller instance.
*
* #return void
*/
public function __construct()
{
$this->middleware('auth');
}
/**
* Display a listing of the resource.
*
* #return \Illuminate\Http\Response
*/
public function index()
{
// $viewpinjaman = DetailPinjamanView::all();
$this->authorize('inventaris_add', $user);
$inventaris = Inventaris::all();
return view('index', compact('inventaris'));
}
I have a main template file and it's called by different controllers and different views. In footer the list of categories display so how can i pass data from all controller`s method without writing code in all functions and pass data?
get categories in app/Providers/AppServiceProvider.php boot method
namespace App\Providers;
use Illuminate\Support\Facades\View;
use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\Schema;
use Illuminate\Support\Facades\Auth;
use DB;
class AppServiceProvider extends ServiceProvider
{
/**
* Bootstrap any application services.
*
* #return void
*/
public function boot()
{
View::share('key', 'value');
Schema::defaultStringLength(191);
$categories=DB::table('categories')->get();
View::share('categories',$categories);
}
/**
* Register any application services.
*
* #return void
*/
public function register()
{
//
}
}
now you can access categories in all views and controllers in $categories variable
in your footer :
#foreach($categories as $category)
<p>{{$category->name}}</p>
#endforeach
I am trying to get a mailable setup which has a collection of files. Mail controller looks like:
<?php
namespace App\Mail;
use App\Document;
use App\Order;
use Illuminate\Bus\Queueable;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;
use Illuminate\Contracts\Queue\ShouldQueue;
use App\User;
class OrderComplete extends Mailable
{
use Queueable, SerializesModels;
public $user;
public $order;
public $documents;
/**
* Create a new message instance.
*
* #return void
*/
public function __construct(User $user, Order $order, Document $document)
{
//
$this->user = $user;
$this->order = $order;
$this->documents = $document;
}
/**
* Build the message.
*
* #return $this
*/
public function build()
{
return $this->markdown('emails.customers.complete');
}
}
Controller calling the mailable looks like;
use App\Document;
// other code...
$documents = Document::where('order_id', $orderId)
->where('product', 'like', '%response')
->get();
Mail::to($customer)
->send(new OrderComplete($customer, $order, $documents));
But I keep getting this error:
Type error: Argument 3 passed to App\Mail\OrderComplete::__construct() must be an instance of App\Document, instance of Illuminate\Database\Eloquent\Collection given, called in /Users/ap/sites/propair/app/Http/Controllers/OrderController.php on line 253
I'm pretty confused as I thought this should work?
thanks
This function declaration:
public function __construct(..., Document $document)
means PHP will enforce that $document is an instance of App\Document.
If you want to pass it a collection instead, you'll need to do:
public function __construct(..., \Illuminate\Database\Eloquent\Collection $documents)
Im working on a Laravel 5 app and im trying to set up a ComposerServiceProvider to pass data to a couple of views (im trying now to add it to the layout/app.blade.php).
I did this following the documentation but the data im trying to add is still undefined..
In my config/app.php I added to the providers:
App\Providers\ComposerServiceProvider::class,
On ComposerServiceProvider.php
boot method:
View::composer(['layouts.app'], 'App\ViewComposers\LayoutAppComposer');
On the new created LayoutAppComposer.php
compose(View $view) method:
$metaTitle = 'MetaTitle';
$view->with('metaTitle', $metaTitle)
But When i access the url I still get:
Undefined variable: metaTitle (View: .../resources/views/layouts/app.blade.php)
Am I missing something here??
ServiceProvider
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\View;
class ComposerServiceProvider extends ServiceProvider
{
/**
* Bootstrap the application services.
*
* #return void
*/
public function boot()
{
View::composer(['layouts.app'], 'App\ViewComposers\LayoutAppComposer');
}
/**
* Register the application services.
*
* #return void
*/
public function register()
{
}
}
LayoutAppComposer
<?php
namespace App\ViewComposers;
use Illuminate\Support\Facades\Session;
use Illuminate\View\View;
class LayoutAppComposer {
protected $metaTitle;
public function __construct($metaTitle)
{
$this->metaTitle = $metaTitle;
}
/**
* Bind data to the view.
*
* #param View $view
* #return void
*/
public function compose(View $view) {
$this->metaTitle = 'MetaTitle';
$view->with('metaTitle', $this->metaTitle);
}
}
Try changing:
$metaTitle = 'MetaTitle';
$view->with('metaTitle', $metaTitle)
to
$this->metaTitle = 'metaTitle';
$view->with('metaTitle', $this->metaTitle)
setup $this->metaTitle as a protected class member and assign it in the composer constructor. it may be that $metaTitle is getting garbage collected before you use it since this being resolved at the service provider level.
Since you're registering the composer with your app layout, instead you may need to use the wildcard character in place of app.layout like such:
View::composer('*', function ($view) {
//
});
To resolve $metaTile for the View Composer, try binding in your AppServiceProvider:
$this->app->bind('metaTitle', 'the string i want displayed across all views');
I have an error when simply put this
->paginate(15);
what is wrong with my code below
<?php namespace App\Http\Controllers;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use App\Order;
use Illuminate\Http\Request;
use Illuminate\Pagination\LengthAwarePaginator;
use Illuminate\Pagination\Paginator as Paginator;
class OrderController extends Controller {
/**
* Create a new controller instance.
*
* #return void
*/
public function __construct()
{
$this->middleware('auth');
}
/**
* Display a listing of the resource.
*
* #return Response
*/
public function index()
{
$orders = Order::with('customer')->get()->paginate(5);
return view('order.index', compact('orders'));
}
}
appreciate if you someone can highlight to me what have I done wrong?
Remove the get() when you use paginate()
$orders = Order::with('customer')->paginate(15);
