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'));
}
}

I am trying to execute simple CRUD operation using laravel. but it gives an error code 500 , when I try to fetch data from table either by laravel framework as well as with plain PHP.
Here is my controller class.
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\BookModel;
use \DB;
class AdminController extends Controller
{
function getItems()
{
$data = DB::select('select * from book');
$data = BookModel::all();
echo($data);
return compact('data');
}
}
axiom , which is been used. ---> "https://unpkg.com/axios/dist/axios.min.js"
Model Class:
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class BookModel extends Model {
protected $table = "book";
public $timestamps = false;
}
It is returning no result from the table.
It worked after I changed my controller to
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\BookModel;
use \DB;
class AdminController extends Controller
{
function getItems()
{
$data = BookModel::all();
return $data;
}
}
But it was giving null result when I was doing something like below
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\BookModel;
use \DB;
class AdminController extends Controller
{
function getItems()
{
$data = BookModel::all();
return view('admin')->withTasks($data);
}
}
Can someone explain why it was not working earlier?
Anyways , Thanks everyone for your help.
Cheeeeeeeeerrsssss!!!!!!!
You need to add response() to return data without view.
Like below the code returns the JSON data from your BookModel that sometimes we need through the ajax request like axios.
class AdminController extends Controller
{
function getItems()
{
$data = BookModel::all();
return response()->toJson($data);
}
}
With view you can do the following:
class AdminController extends Controller
{
function getItems()
{
$data = BookModel::all();
return view('admin', compact('data'));
}
}
Where you can access the BookModel data through $data variable in your admin.blade.php
I created a Mailable called Class UserRequest
I'm trying to call it from inside a controller buy this is the error I get:
Class 'App\Http\Controllers\UserRequest' not found
I also tried ->send(new \UserRequest($msgdata)); but it still doesn't work.
Controller:
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Mail;
class ContactController extends Controller
{
public function index()
{
return view('contact');
}
public function sendemail(Request $request)
{
$msgdata = array('subject'=>$request->subject,'email'=>$request->email, 'name'=>$request->name,'body'=>$request->body);
try
{
Mail::to('dddddddd#dddsdsf.com')
->send(new UserRequest($msgdata));
}
catch(Exception $e)
{
}
}
}
Include your class at the top like this
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Mail;
use App\Mail\UserRequest; // including your class
class ContactController extends Controller
{
public function index()
{
return view('contact');
}
public function sendemail(Request $request){
$msgdata = array('subject'=>$request->subject,'email'=>$request->email,
'name'=>$request->name,'body'=>$request->body);
try {
Mail::to('dddddddd#dddsdsf.com')->send(new UserRequest($msgdata));
}catch(Exception $e){
// Log your exception
}
}
}
add 'App\Http\Controllers\UserRequest' to the head
use App\Http\Controllers\UserRequest;
at the top.
You will need to add the right path to the top as stated by other.
Also check the namespace in the UserRequest class
I am using laravel 5.2,
I have created admin controller and added logic to check admin role in constructor
namespace App\Http\Controllers;
use Sentinel;
class AdminController extends Controller
{
public function __construct()
{
if(Sentinel::check())
{
if(!Sentinel::inRole('admin'))
{
return redirect("login");
}
}
else
{
return redirect("login");
}
}
}
and I extends this controller on some admin controller
namespace App\Http\Controllers;
use Request;
use App\Http\Controllers\AdminController;
use App\Http\Requests;
use Sentinel;
use App\User;
use DB;
class UserController extends AdminController
{
function __construct()
{
parent::__construct();
}
}
When I call user controller admin constructor is called but return function is not working properly, if I add die; before return it get die, but after return notthing is affected.
so it doesn't return redirect function properly.
The ugly workaround would be to pass a boolean param to Papa indicating that you do not wish to parse the code contained in it's constructor. i.e:
// main class that everything inherits
class Grandpa extends Controller
{
public function __construct()
{
}
}
class Papa extends Grandpa
{
public function __construct($bypass = false)
{
// only perform actions inside if not bypassing
if (!$bypass) {
}
// call Grandpa's constructor
parent::__construct();
}
}
class Kiddo extends Papa
{
public function __construct()
{
$bypassPapa = true;
parent::__construct($bypassPapa);
}
}
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 $this->obavjesti;
}
}
I have following function and want to call it from view. Basically i want to put all common functions in one file. I am not sure where to create that file and how to call it inside controller and view.
<?php namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use DB;
class CommonController extends Controller {
public function BytesToMB($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');
}
}
