I have a model config which has the following at the top:
<?php
namespace App;
use DB;
use Illuminate\Database\Eloquent\Model;
class Config extends Model
{
protected $table = 'config';
public function getConfigVariables()
{
$config = DB::table('config')->where('is', '1')->first();
session()->put('name',$config['name']);
session()->put('infoemail',$config['infoemail']);
session()->put('copyrightowner',$config['copyrightowner']);
and I wish to call this in a controller to set up the session so in the route for the top level I set set up
Route::get('/',
[
'uses' => 'ConfigController#ConfigVariables',
'as' => 'home'
]);
The config controller method which does not work is:
public function ConfigVariables()
{
Config::getConfigVariables();
session()->put('thisyear',ReturnCurrentYear());
$footer = "© ".session()->get('thisyear').", ".session()->get('name');
session()->put('footer',$footer);
return view('welcome');
}
but this does not work and I am stuck!
Change
public function getConfigVariables()
to
public static function getConfigVariables()
You might want to read up how object oriented works, basically when you do Config::getConfigVariables(); you are trying to call a static method, without instantiating the class.
A good start would be here, the concept applies everywhere.

I am trying to add data to a layout variable via a controller constructor. The reason I want to do this is because I always need to add categories to the topmenu when this controller is called.
No success so far. I add data to a layout via a view composer like this.
namespace App\Http\ViewComposers;
use Illuminate\View\View;
use App\Menu;
class MenuComposer
{
public function compose(View $view)
{
if (in_array($view->getName(), ['layouts.master', 'layouts.master-post', 'layouts.error']))
{
$menu = Menu::menu('topmenu');
view()->with('topmenu', $menu);
// view()->share('topmenu', $menu); not working either
}
}
}
I want to extend the data in a Controller constructor.
namespace App\Http\Controllers\Post;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use Illuminate\View\View;
class PostController extends Controller {
public function __construct(View $view)
{
$view->offsetGet('topmenu');
// $view->gatherData() not working either
}
Whatever I try, Laravel throws an exception:
Target [Illuminate\Contracts\View\Engine] is not instantiable while building [App\Http\Controllers\Post\PostController, Illuminate\View\View].
What I did in the serviceprovider boot function:
view()->share('topmenu', [
'items' => $newItemsToAdd
]);
In the viewComposer I did:
$extraItems = view()->shared('topmenu');
if (!empty($extraItems)) {
$items = aray_merge($items, $extraItems);
}
}
How to share one method to all controllers with different DI, view and parameters? I need something like this:
public function method(Model $model)
{
$baseData = [
'model' => $model,
'route' => route('$route', [$param => $model]),
];
return view($view);
}
All controllers extend App\Http\Controllers\Controller so you can just place it there
<?php
namespace App\Http\Controllers;
use Illuminate\Database\Eloquent\Model;
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;
public function method(Model $model, $route, $param, $view)
{
// Declared but not used
$baseData = [
'model' => $model,
'route' => route($route, [$param => $model]),
];
return view($view);
}
}
And use it with $this->method()
For example in HomeController
<?php
namespace App\Http\Controllers;
use App\User;
class HomeController extends Controller
{
/**
* Show the application dashboard.
*
* #return \Illuminate\Contracts\Support\Renderable
*/
public function index()
{
$user = User::first();
return $this->method($user, 'home', 'user', 'welcome');
}
}
Now accessing domain.tld/home will return the welcome view
If you want to share function to all controller best way will make service in service folder of app.
step to make service:-
1.create service using artisan command
php artisan make:service service_name and define function that to share to all controller in your project.
after making service your have to register this service with provider.make a provider using artisan command.
php artisan make provider:provider_name and you will see 2 function register and boot
register function is used to register your created service and boot for call already register service
register service like this
public function register()
{
$this->app->bind('App\Services\servicename', function( $app ){
return new serviceclassname;
});
}
3.Go config folder ,open app.php where you will get providers array. In this provider you have to define you provider like App\Providers\providerclassname::class,
call this service in controllers like use App\Services\serviceclassname;
public function functionname(serviceclassname serviceobject)
{
serviceobject->functionname();
}
After creating several Apps with Laravel and using softDelete properties I realized that methods like destroy(), restore() and kill() are exactly the same among several controllers. Therefore I am trying to put themn in a trait and use it from diferent Controllers.
My code is as follows:
ProfilesController.php
<?php
namespace App\Http\Controllers;
use App\Profile;
class ProfilesController extends Controller
{
public function destroy(Profile $profile)
{
Profile::del($profile, 'profiles');
return redirect()->route('profiles.index');
}
public function trashed()
{
Profile::trash('Profile');
}
}
Profile.php (model)
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;
class Profile extends Model
{
protected $fillable = ['user_id', 'role_id', 'title', 'subtitle', 'slug', 'birthday', 'about'];
use SoftDeletes, Helpers, commonMethods;
public function getRouteKeyName()
{
return 'slug';
}
// ... more code here
}
trait file: commonMethods.php
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\Facades\Auth;
use App\Profile;
use Session;
trait commonMethods
{
public static function del($element, $page_name)
{
$element->delete();
Session::flash('success', $element . ' successfully deleted!');
}
public static function trash($model)
{
$total = $model::onlyTrashed()->get();
$total_tr = count($total);
$all_tr = $model::all();
return view('partials.templates.trashed', compact('total', 'total_tr', 'all_tr'));
}
// ...more code here
}
The problem:
I try to visit the view "Trashed" that will list all elements "softdeleted" but not "killed", the method.
I pass the $model variable with the method trash($model)
I get the following error:
Class App/Profile does not found. Try to call App/Profile
I have debugged and the $model variable contains exactly what I need, the string 'Profile' which is what I need to build the Query:
$total = Profile::onlyTrashed()->get();
This query works while in the ProfilesController, but does not work while in a trait, since the model class is not found.
Any idea how could I make it work?
I am using Laravel 6.
If you need to use a class as a string you will want to use its full name. 'App\Profile' instead of 'Profile'.
$model = 'Profile';
new $model; // will use `\Profile`
$model = 'App\Profile';
new $model; // will use '\App\Profile';
In your controller( ProfilesController ) write :
use App\Profile;
In your model write :
use App\commonMethods;
My project is multi language, so in most route I add parameter "locale". But latter I do not need to pass "locale" parameter to my controllers. I try to remove this parameter using forgetParameter() method but when I use this method then I have error "Route not bound".
So what I'm doing wrong.
How to remove "locale" from all routes?
Laravel 5.8
My route file.
Route::group(['prefix' => '{locale}','where' => ['locale' => '[a-zA-Z]{2}']], function() {
Auth::routes([app()->getLocale()]);
Route::get('/', 'HomeController#index')->name('mainPage');
Route::get('/user/{id}','UserController#showUser')->name('getUserProfile')->forgetParameter('locale');
Route::get('/user/{id}/edit','UserController#editUser')->name('editUserProfile')
->middleware('can:editUser,App\User,id')->forgetParameter('locale');
Route::patch('/user/{id}/edit','UserController#updateUser')->name('updateUserProfile')
->middleware('can:updateUser,App\User,id')->forgetParameter('locale');
});
It's not duplicate with this question - Laravel 5.4: How to DO NOT use route parameter in controller
Solution in that question doesn't work in my case. And my question is why "forgotParamter()" throw an error?
Other question is, why I can't use this construction in middleware:
$request->route()->forgetParameter('locale')
I have following error:
Call to a member function is() on null
Thank you.
Try to forget the parameter in an inline middleware in the controller's constructor. Actually, I would use a base controller: 1, get the route value; 2, set to a protected property, so inherited controllers can access to the value; 3, forget the parameter.
<?php
// Localized/Controller.php
namespace App\Http\Controllers\Localized;
use App\Http\Controllers\Controller as ControllerBase;
use Illuminate\Http\Request;
class Controller extends ControllerBase
{
protected string $currentLocale;
public function __construct()
{
$this->middleware(function ($request, $next) {
// If you need to access this later on inherited controllers
$this->currentLocale = $request->route('locale') ?? 'en';
// Other operations, like setting the locale or check if lang is available, etc
$request->route()->forgetParameter('locale');
return $next($request);
});
}
}
<?php
// Localized/UserController.php
namespace App\Http\Controllers\Localized;
use Illuminate\Http\Request;
// Extends the our base controller instead of App\Http\Controllers\Controller
class UserController extends Controller
{
public function show(Request $request)
{
// No need of string $locale arg
dd($this->currentLocale);
}
}
In laravel i have defined a route like this
Route::get('/', array(){
'as' => 'index',
'uses' => 'HomeController#index'
});
The function index() in the HomeController contains
public function index(){
$index = new ExampleModel;
$data = $index->getExampleList();
return View::make('public.index');
}
Now the problem is i have a master layout called happypath inside layouts folder in my views which yields this public.index content and i need to pass this $data to layouts.happypath. How do i do this ?
You can use a view composer for example:
namespace App\Providers;
use App\ExampleModel;
use Illuminate\Support\ServiceProvider;
class ComposerServiceProvider extends ServiceProvider
{
protected $exampleModel;
public function __construct(ExampleModel $exampleModel)
{
$this->exampleModel = $exampleModel;
}
public function boot()
{
view()->composer('layouts.happypath', function ($view) {
$view->with('publicIndex', $this->exampleModel->getExampleList());
});
}
public function register()
{
//
}
}
So, every time you use/render the layouts.happypath the $publicIndex variable will be attached within the layout. Also you need to add the ComposerServiceProvider class in your config/app.php file in the providers array. You may access/reference the data using $publicIndex variable in your layout. There are other ways like global shared $information using view()->share(...) method to share a peace of data all over the views but this may help you.
I could not figure out the ComposerServiceProvider View::composer thing. So i basically solved it like this in Laravel 4.2. Added this code to the BaseController.php
protected $menuList;
public function __construct() {
$response = API::pool([
['GET', API::url('level')],
]);
$index = new Index();
$index->setCourseList($response[0]->json()['Category']);
$result = $index->getCourseList();
View::share('result', $result); //This line shares the $result globally across all the views in laravel 4.2
}
This can be done with a Service Provider. You can either use an existing one or create a new one.
<?php
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
use App\ExampleModel;
class ViewServiceProvider extends ServiceProvider
{
public function boot()
{
$index = new ExampleModel;
$data = $index->getExampleList();
view()->share('public.index', $data);
}
public function register()
{
}
}
