Laravel 5 fails to pass variable to all views - php

I have a problem with passing variable (data) to all Views. I created BaseController that extends default Laravel controller and "global" variables are defined there. When I extend other controller with BaseController i got error that variable is not defined. Does someone knows where's the problem?
Here is code:
namespace App\Http\Controllers;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use Sentry;
use Illuminate\Http\Request;
use View;
class BaseController extends Controller {
public function __construct() {
$obavijesti="Other data";
$izbornici="Some data";
View::share ( 'izbornici', $izbornici );
View::share ( 'obavjesti', $obavjesti );
}
}
class AdminController extends BaseController {
.
.
.
echo '<pre>';var_dump($izbornici);echo '</pre>';//Error pop ups here
.
.
.
}

You are doing something wrong here. view::share() is used for sharing a piece of data across all views not controller.
namespace App\Http\Controllers;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use Sentry;
use Illuminate\Http\Request;
use View;
//If you wish to get these variables in your other controllers you do this:
class BaseController extends Controller {
public $obavijesti="Other data";
public $izbornici="Some data";
public function __construct() {
View::share ( 'izbornici', $this->izbornici );
View::share ( 'obavjesti', $this->obavjesti );
}
}
class AdminController extends BaseController {
//if you have a constructor in other controllers you need call constructor of parent controller (i.e. BaseController) like so:
public function __construct(){
parent::__construct();
}
public function Index(){
echo $this->obavijesti;
}
}
You can also use a composer to share variables to views
//1. Create a composer file at app\Composers\AdminComposer.php
//NB: create "app\Composers" if does not exists
//2. Inside AdminComposer.php add this.
<?php namespace App\Composers;
class AdminComposer
{
public function __construct()
{
}
public function compose($view)
{
//Add your variables
$view->with('izbornici', 'Other data')
->with('obavjesti', 'Some other data');
}
}
//3. In you controller do this:
<?php namespace App\Http\Controllers;
//NB: I removed your BaseController because I believe the issue is coming from //there
use App\Http\Requests;
use App\Http\Controllers\Controller;
use Sentry;
use Illuminate\Http\Request;
use View;
class AdminController extends Controller{
public function __construct(){
//Lets use AdminComposer to share variables to adminpage.blade.php view
View::composers([
'App\Composers\AdminComposer' => array('adminpage')
]);
}
public function Index(){
return view('adminpage');
}
}

Ideally you're going to want a combination of what you have, and the other answer posted here.
<?php
class BaseController extends Controller {
protected $obavijesti = 'Other data';
protected $izbornici = 'Some data';
public function __construct() {
View::share('obavjesti', $this->obavjesti);
View::share('izbornici', $this->izbornici);
}
}
Then in all of your views, you have access to the variables $obavjesti and $izbornici. Now in your other controllers, anything that extends BaseController can do the following:
class AdminController extends BaseController {
public function index() {
echo $this->ixbornici;
echo $this->obavjesti;
}
}

How to create a method that you can call in all other controllers in Laravel 7

Greetings guys i'm having a challenge figuring out how to make this method in the base controller so that i initialize it there and call it in all other controllers that i wish.
I want to create this in the base controller , then call it in other controllers
$paynow = new Paynow(
'9644',
'7e3bebb4-6dbf-4f8f-9e10-aceafd02c8db',
'Return_url',
'Result_url'
);
Images
1.This is what i have done in the base controller
Image 2. This is where im trying to use it to call its member functions
Image 3. Is the error that im getting
<?php
namespace App\Http\Controllers;
use Illuminate\Foundation\Auth\Access\AuthorizesRequests;
use Illuminate\Foundation\Bus\DispatchesJobs;
use Illuminate\Foundation\Validation\ValidatesRequests;
use Illuminate\Routing\Controller as BaseController;
class Controller extends BaseController
{
use AuthorizesRequests, DispatchesJobs, ValidatesRequests;
protected function callPayNow()
{
return new Paynow(
'9644',
'7e3bebb4-6dbf-4f8f-9e10-aceafd02c8db',
'Return_url',
'Result_url'
);
}
}
In your AnyController
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class AnyController extends Controller
{
public function anyMethod()
{
$this->callPayNow();
}
}
if I undersend you well,
Maybe the best approach is to create new controller that extends BasController:
class Controller extends BaseController
{
public function payNow()
{
return new Paynow(
'9644',
'7e3bebb4-6dbf-4f8f-9e10-aceafd02c8db',
'Return_url',
'Result_url'
);
}
}
And then in your other controller you can extend your new controller:
class UserController extends Controller
{
//For example
public function show($id, Request $request)
{
$payNow = $this->payNow();
$payment = $payNow->createPayment($currentOrder, $request->get('email'));
return response()->json("done");
}
}
Paynow will be called in every controller that extends this controller.

Class App\Http\Controllers\Panel does not exist

I'm following the Laracasts series and have run into an issue on the episode Laravel 5.4 From Scratch: Route Model Binding.
Laravel version:
Laravel Framework 5.6.13
The error:
Class App\Http\Controllers\Panel does not exist
This shows on both the /panel and /panel/1 pages
App\Http\Controllers\PanelController.php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
// Code works if I uncomment below line, and change the show function to "show($panel)"
//use App;
class PanelController extends Controller
{
public function index()
{
$panels = Panel::all();
return view('panel/index', compact('panels'));
}
public function show(Panel $panel)
{
return $panel;
return view('panel/show', compact('panel'));
}
}
routes/web.php
// Main panel view
Route::get('/panel', 'PanelController#index');
// Individual panel view
Route::get('/panel/{panel}', 'PanelController#show');
App/Panel.php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Panel extends Model
{
public static function activePanels()
{
return static::where('status', 1)->get();
}
}
Add this line in panel controller before the class
use App\Panel;
You need to add use App\Panel; to top of class
Or call it by full namespace $panels = App\Panel::all();
You don't included your model to class.
Add App\Panel to main include section:
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Panel;
class PanelController extends Controller
{
public function index()
{
$panels = Panel::all();
return view('panel/index', compact('panels'));
}
public function show(Panel $panel)
{
return $panel;
return view('panel/show', compact('panel'));
}
}
or load model in your class method manually:
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class PanelController extends Controller
{
public function index()
{
$panels = App\Panel::all();
return view('panel/index', compact('panels'));
}
public function show(Panel $panel)
{
return $panel;
return view('panel/show', compact('panel'));
}
}

Why I didnt see the result in my extended constructor in Laravel

I have few classes which extends from the abstract class
And Class MenuController Extends from SiteAdminController
I need to call MenuController and receive authenticated user id
<?php
namespace App\Http\Controllers\SiteAdmin;
use App\Http\Categories;
use Illuminate\Http\Request;
use Gate;
use App\Category;
use App\Http\Controllers\MenuController;
use App\Site_categories;
use Auth;
class SiteAdminController extends \App\Http\SiteEntity implements Categories
{
protected $host;
public $user;
public function __construct()
{
parent::__construct();
$this->middleware('auth:admin');
}
protected function menu() {
return $data_nav['menu'] = MenuController::index('admin_categories');
}
Other one extends from SiteAdminCntroller
<?php
namespace App\Http\Controllers\SiteAdmin;
use Illuminate\Http\Request;
use Gate;
use Auth;
use App\Category;
class MenuController extends SiteAdminController
{
public $category_menu;
public $user_categories;
public $user;
public function __construct(Auth $auth)
{
//parent::__construct();
$this->user_categories=$this->CategoriesMenu();
$this->user=$auth::guard('admin')->user()->id;
dd($this->user);
//dd($this->user_categories);
}
I think the constructor in the MenuController run befor the middlware in SiteAdminController
Thats why I have such error
http://prntscr.com/hwfifx
Please Explaine what have I do to see result from me dd() function?
I was trying even to call parent::__construct but it not helping
You are correct that the the code in the constructor runs before the middleware: https://github.com/laravel/framework/issues/15072
The easiest way to get around this is to use the middleware method in the controller:
MenuController
public function __construct()
{
parent::__construct();
$this->middleware(function () {
$this->user_categories = $this->CategoriesMenu();
$this->user = auth()->guard('admin')->user()->id;
});
}
First of all check if the class see another class that must be extended with.
Then try below approach (it s just example):
class ConceptController extends \SiteAdminController {
public function __construct(SiteAdminController $siteAdmin) {
parent::__construct($siteAdmin);
}
}

How to Access to Laravel 5 with Pingpong-Modules to a specific Module

I am new to Laravel 5 and Pingpong-Modules https://github.com/pingpong-labs/modules
I want to Access from an outsite of the Modules-Directory to a Specific Module-Function.
My Actual Configuration is:
I want to access to the Method "test()" from the DashboardController - what is here the best practice?
Code of Controller 1:
<?php namespace App\Http\Controllers\Admin;
use App\Http\Controllers\AdminController;
use App\News;
use App\NewsCategory;
use App\User;
use App\Video;
use App\VideoAlbum;
use App\Photo;
use App\PhotoAlbum;
use \Pingpong\Modules\Facades\Module;
use App\Helpers\ModulesHelper;
class DashboardController extends AdminController {
public function __construct()
{
parent::__construct();
}
public function index()
{
$title = "Dashboard";
$news = News::count();
$newscategory = NewsCategory::count();
$users = User::count();
$photo = Photo::count();
$photoalbum = PhotoAlbum::count();
$video = Video::count();
$videoalbum = VideoAlbum::count();
return view('admin.dashboard.index', compact('title','news','newscategory','video','videoalbum','photo',
'photoalbum','users'));
}
Code of Controller 2:
<?php namespace Modules\Users\Http\Controllers;
use Illuminate\Routing\Controller;
use Illuminate\Support\Facades\View;
class UsersController extends Controller {
public function index()
{
return View::make('users::index');
}
public function test() {
return "TEST";
}
}
Put this block wherever you want in DashboardController:
$usersController = App::make('Modules\Users\Http\Controllers\UsersController');
$usersController->test();

Laravel 5 - Where to define functions and call them in views & controllers

I have following function and want to call it from view. Basically i want to put all common functions in one file. I am not sure where to create that file and how to call it inside controller and view.
<?php namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use DB;
class CommonController extends Controller {
public function BytesToMB($bytes=0)
{
if(empty($bytes))
return 0;
$kb = ceil($bytes/1024);
$mb = ceil($kb/1024);
return $mb;
}
}
So far i have created CommonController.php in app/Http/Controllers and put above function in it.
Then in other controller i have tried to call it following way:
use App\Http\Controllers\Common;
class SongsController extends Controller {
public function index($id)
{
echo Common::BytesToMB('7012187');
}
}
But i am getting error:
Class 'App\Http\Controllers\Common' not found
Ok, new try. You missed to use the complete class name and add the static keyword:
<?php
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use DB;
class CommonController extends Controller {
public static function BytesToMB($bytes=0)
{
if(empty($bytes))
return 0;
$kb = ceil($bytes/1024);
$mb = ceil($kb/1024);
return $mb;
}
}
And then:
<?php
namespace App\Http\Controllers;
// You do not need to define this, if you are in the same namespace
use App\Http\Controllers\CommonController;
class SongsController extends Controller {
public function index($id)
{
echo CommonController::BytesToMB('7012187');
}
}
Another and more OOP solution is to use the function from the parent class:
<?php
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use DB;
class CommonController extends Controller {
protected function BytesToMB($bytes=0)
{
if(empty($bytes))
return 0;
$kb = ceil($bytes/1024);
$mb = ceil($kb/1024);
return $mb;
}
}
And then:
<?php
namespace App\Http\Controllers;
// You do not need to define this, if you are in the same namespace
use App\Http\Controllers\CommonController;
class SongsController extends CommonController {
public function index($id)
{
echo $this->bytesToMB('7012187');
}
}
