I am trying to write some custom helper functions for my Laravel 9 app using the advice given in the second answer (written by heisian) to this question. I think I've imitated everything faithfully but when I try to use the new function, intelephense says "Undefined type 'Helper'.
Here is my Helper.php (stored in app/Helpers/Helper.php):
<?php
namespace App\Helpers;
class Helper {
public static function hello() {
return "Hello!";
}
}
?>
Here is the only section I changed in config/app.php:
'aliases' => Facade::defaultAliases()->merge([
// 'ExampleClass' => App\Example\ExampleClass::class,
'Helper' => App\Helpers\Helper::class
])->toArray(),
Here is the part of my code where I actually use the new hello() function:
<?php
namespace Database\Factories;
use Illuminate\Database\Eloquent\Factories\Factory;
use Helper;
/**
* #extends \Illuminate\Database\Eloquent\Factories\Factory<\App\Models\Listing>
*/
class ListingFactory extends Factory
{
/**
* Define the model's default state.
*
* #return array<string, mixed>
*/
public function definition()
{
$this->faker = \Faker\Factory::create();
/* Choose a single job title at random from the collection of job titles. */
// $titlesCollection = collect(['Junior Laravel Developer', 'Intermediate Laravel Developer', 'Senior Laravel Developer', 'Laravel Project Leader']);
// $randomTitleString = $titlesCollection->random();
$randomTitleString = Helper::hello();
Intelephense highlights the final line of this excerpt by putting a red squiggly line under Helper. I can make the error go away by changing:
use Helper;
to
use app\Helpers\Helper;
However, if I then try to execute php artisan migrate:refresh --seed I get a different error. However, the refresh/seed WORKS with use Helper; despite the error and the hello() function does exactly what I've told it to do. (I should mention that I have done the composer dump-autoload on my terminal as per the instructions in the linked question.)
Ultimately, the only real problem here is that Intelephense doesn't recognize the Helper class for what it is. Short of uninstalling Intelephense from my copy of VS Code, is there anything I can do to make it recognize that Helper is a legitimate class?
I am using Laravel 8 and I have installed InertiaJS, but in my directory resources/views/ I have a single file called index.blade.php which I plan to use with InertiaJS.
By default, InertiaJS looks for a file inside that directory called app.blade.php. I know writing the following statement:
\Inertia\Inertia::setRootView('index');
Change the rootView and allow me to use the file I have created. It may seem like a stupid question, but as far as I see it, I can do 2 things ..
Rename file index.blade.php to app.blade.php
Write the previous sentence .. in one of the ServiceProviders that I have
I wonder the following:
InertiaJS-Laravel does not allow publishing a ServiceProvider with the command php artisan vendor:publish? (the output of this command does not show me anything to publish regarding this package)
To solve my problem I should create a ServiceProvider like: php artisan make:provider InertiaServiceProvider and then register it?
Or just add the previous statement to one of the ServiceProvider that already exist? Like in app/Http/Providers/RouteServiceProvider.php
What do you recommend that would be better?
I want to seek the largest possible organization in my project. Thank you very much in advance...
Update; after my initial answer (on 20-09-2020), Inertia introduced middleware to handle your Inertia requests.
As described in the answers below, you can use the command php artisan inertia:middleware to generate this middleware. You can set the root index with:
// Set root template via property
protected $rootView = 'app';
// OR
// Set root template via method
public function rootView(Request $request)
{
return 'app';
}
You can find more info in the docs.
Even tighter, just override the rootView method in App\Http\Middleware\HandleInertiaRequests like this...
public function rootView(Request $request)
{
if ($request->route()->getPrefix() == 'admin') {
return 'layout.admin';
}
return parent::rootView($request);
}
You can do this inside your controller on the fly.
<?php
namespace App\Http\Controllers;
use App\Models\User;
use Illuminate\Http\Request;
use Inertia\Inertia;
class NewsController extends Controller
{
public function index()
{
Inertia::setRootView('layouts.news');
$users = User::all();
return Inertia::render('News/Index', compact('users'));
}
}
Replace in the App\Http\Middleware\HandleInertiaRequests
protected $rootView = 'app';
with:
public function rootView(Request $request): string
{
if ($request->route()->getPrefix() === '/admin') {
return 'admin.app';
}
return 'app';
}
I think it would be easier to change it in App\Http\Middleware\HandleInertiaRequests.
Be sure to run php artisan inertia:middleware during inertia server-side installation.
Also include it in your web middleware group.
Then go to App\Http\Middleware\HandleInertiaRequests and change the $rootView property to the name of the blade file you want to use. Example:
protected $rootView = 'index';
Extended #Olu Udeh answer
overwrite handle method of App\Http\Middleware\HandleInertiaRequests middleware
public function handle(Request $request, Closure $next)
{
if($request->route()->getPrefix() == 'admin'){
$this->rootView = 'layouts.admin';
}
return parent::handle($request, $next);
}
In laravel 8 this work for me
App\Http\Middleware\HandleInertiaRequests
Code
public function rootView(Request $request)
{
if(request()->is('admin/*') or request()->is('admin'))
{
return 'admin';
}
return parent::rootView($request);
}
I am building an app where each company have multiple users. And all users can upload documents/images/xls etc. I want to keep all company data in company separate folder. To complete this I am checking the company detail for every user and then upload data to company specific folder. Can I check company database once per user login and share user's company details to all controller and can easily access.
Use view composer in your AppServiceProvider
App\Providers\AppServiceProvider.php
class AppServiceProvider extends ServiceProvider
{
public function boot()
{
view()->composer('*',function($view) {
if(auth()->user()) {
$comanyData = App\Company::where('user_id',auth()->user()->id);
$view->with('companyData', $companyData);
}
});
}
}
You can make the helper function to use in controllers or blades files.
Let’s create a helper!
Create a simple PHP file.
Create Helper.php inside the app directory or wherever directory you want.
<?php
/**
* get company data
*
*/
function companyData()
{
// Create logic of company data
// return company data
}
Autoload Composer
After we created our helper, Laravel won’t recognize our file so we need to register the helper file to our composer.json. Add File array inside the autoload section. It may look like this:
"autoload": {
"classmap": ["database"],
"psr-4": {"App\\": "app/"},
"files" : ["app/Helper.php"]
}
Then don’t forget to run
composer dumpautoload
Using helper function
Our helper is autoloaded now, so we should be able to use our helper immediately on different controllers. Just call our function in any class
$companyData = companyData();
or in blade view
{{ companyData() }}
Let me know if you are facing an issue.
Below is how to share a variable with your entire application via the AppServiceProvider, You can also do this inside of your base controller in the construct method.
File: App\Providers\AppServiceProvider.php
<?php
namespace App\Providers;
use View;
use Illuminate\Support\ServiceProvider;
class AppServiceProvider extends ServiceProvider
{
/**
* Register any application services.
*
* #return void
*/
public function register()
{
//
}
/**
* Bootstrap any application services.
*
* #return void
*/
public function boot()
{
View::share('key', 'value');
}
}
You can then access $key inside of any view.
With the release of Laravel 5.7 the Illuminate\Notifications\Notification class started offering a locale method to set the desired language. The application will change into this locale when the notification is being formatted and then revert back to the previous locale when formatting is complete. Here is an example of this feature:
$user->notify((new InvoicePaid($invoice))->locale('ar'));
I just need to use this feature in lumen (latest version) but when I implement that Like documentation said I got an error
Call to undefined method Laravel\Lumen\Application::getLocale()
and this because there is no getLocale or setLocale methods in lumen application.. so any ideas to solve this.
Difference between Lumen and Laravel is that in Laravel you call Application->setLocale().
This does three things, as outlined above:
Set config app.locale
Set Locale on the translator
Fire the locale.changed event
In Lumen though, you would call the translator directly with app('translator')->setLocale() or App::make('translator')->setLocale(),
so the difference here is that the config variable will not be set automatically and the locale.changed event will not be fired.
Laravel's Application class also updates the config and fires an event:
public function setLocale($locale)
{
$this['config']->set('app.locale', $locale);
$this['translator']->setLocale($locale);
$this['events']->fire('locale.changed', [$locale]);
}
and in Laravel, getLocale is just reading the config variable:
public function getLocale()
{
return $this['config']->get('app.locale');
}
For translations thought, it's the translator that matters. Laravel's trans helper looks like this:
function trans($id = null, $parameters = [], $domain = 'messages', $locale = null)
{
if (is_null($id)) {
return app('translator');
}
return app('translator')->trans($id, $parameters, $domain, $locale);
}
You need to make your application extends another class with the above 3 methods
You can Extend your Laravel\Lumen\Application in a new class and make $app variable take an instance from your new class in your bootstrap\app.php file
1- create the new class like this:
<?php namespace App\Core;
use Laravel\Lumen\Application as Core;
class Application extends Core
{
/**
* #param $locale
*/
public function setLocale($locale): void
{
$this['config']->set('app.locale', $locale);
$this['translator']->setLocale($locale);
$this['events']->fire('locale.changed', [ $locale ]);
}
public function getLocale()
{
return $this['config']->get('app.locale');
}
}
2- make an instance from your new class ex:
$app = new App\Core\Application(
realpath(dirname(__DIR__) . '/')
);
In Laravel I have a table settings and i have fetched complete data from the table in the BaseController, as following
public function __construct()
{
// Fetch the Site Settings object
$site_settings = Setting::all();
View::share('site_settings', $site_settings);
}
Now i want to access $site_settings. in all other controllers and views so that i don't need to write the same code again and again, so anybody please tell me the solution or any other way so i can fetch the data from the table once and use it in all controllers and view.
Okay, I'm going to completely ignore the ridiculous amount of over engineering and assumptions that the other answers are rife with, and go with the simple option.
If you're okay for there to be a single database call during each request, then the method is simple, alarmingly so:
class BaseController extends \Controller
{
protected $site_settings;
public function __construct()
{
// Fetch the Site Settings object
$this->site_settings = Setting::all();
View::share('site_settings', $this->site_settings);
}
}
Now providing that all of your controllers extend this BaseController, they can just do $this->site_settings.
If you wish to limit the amount of queries across multiple requests, you could use a caching solution as previously provided, but based on your question, the simple answer is a class property.
At first, a config file is appropriate for this kind of things but you may also use another approach, which is as given below (Laravel - 4):
// You can keep this in your filters.php file
App::before(function($request) {
App::singleton('site_settings', function(){
return Setting::all();
});
// If you use this line of code then it'll be available in any view
// as $site_settings but you may also use app('site_settings') as well
View::share('site_settings', app('site_settings'));
});
To get the same data in any controller you may use:
$site_settings = app('site_settings');
There are many ways, just use one or another, which one you prefer but I'm using the Container.
Use the Config class:
Config::set('site_settings', $site_settings);
Config::get('site_settings');
http://laravel.com/docs/4.2/configuration
Configuration values that are set at run-time are only set for the current request, and will not be carried over to subsequent requests.
In Laravel, 5+ you can create a file in the config folder and create variables in that and use that across the app.
For instance, I want to store some information based on the site.
I create a file called site_vars.php,
which looks like this
<?php
return [
'supportEmail' => 'email#gmail.com',
'adminEmail' => 'admin#sitename.com'
];
Now in the routes, controller, views you can access it using
Config::get('site_vars.supportEmail')
In the views if I this
{{ Config::get('site_vars.supportEmail') }}
It will give email#gmail.com
Hope this helps.
EDiT-
You can also define vars in .env file and use them here.
That is the best way in my opinion as it gives you the flexibility to use values that you want on your local machine.
So, you can do something this in the array
'supportEmail' => env('SUPPORT_EMAIL', 'defaultmail#gmail.com')
Important - After you do this, don't forget to do this on production env
php artisan config:cache
In case, there's still some problem, then you can do this (usually it would never happen but still if it ever happens)
php artisan cache:clear
php artisan config:cache
In your local env, always do this after this adding it
php artisan config:clear
It's always a good practice not to cache config vars in local. in case, it was cached, this would remove the cache and would load the new changes.
I see, that this is still needed for 5.4+ and I just had the same problem, but none of the answers were clean enough, so I tried to accomplish the availability with ServiceProviders. Here is what i did:
Created the Provider SettingsServiceProvider
php artisan make:provider SettingsServiceProvider
Created the Model i needed (GlobalSettings)
php artisan make:model GlobalSettings
Edited the generated register method in \App\Providers\SettingsServiceProvider. As you can see, I retrieve my settings using the eloquent model for it with Setting::all().
public function register()
{
$this->app->singleton('App\GlobalSettings', function ($app) {
return new GlobalSettings(Setting::all());
});
}
Defined some useful parameters and methods (including the constructor with the needed Collection parameter) in GlobalSettings
class GlobalSettings extends Model
{
protected $settings;
protected $keyValuePair;
public function __construct(Collection $settings)
{
$this->settings = $settings;
foreach ($settings as $setting){
$this->keyValuePair[$setting->key] = $setting->value;
}
}
public function has(string $key){ /* check key exists */ }
public function contains(string $key){ /* check value exists */ }
public function get(string $key){ /* get by key */ }
}
At last I registered the provider in config/app.php
'providers' => [
// [...]
App\Providers\SettingsServiceProvider::class
]
After clearing the config cache with php artisan config:cache you can use your singleton as follows.
$foo = app(App\GlobalSettings::class);
echo $foo->has("company") ? $foo->get("company") : "Stack Exchange Inc.";
You can read more about service containers and service providers in Laravel Docs > Service Container and Laravel Docs > Service Providers.
This is my first answer and I had not much time to write it down, so the formatting ist a bit spacey, but I hope you get everything.
I forgot to include the boot method of SettingsServiceProvider, to make the settings variable global available in views, so here you go:
public function boot(GlobalSettings $settinsInstance)
{
View::share('globalsettings', $settinsInstance);
}
Before the boot methods are called all providers have been registered, so we can just use our GlobalSettings instance as parameter, so it can be injected by Laravel.
In blade template:
{{ $globalsettings->get("company") }}
View::share('site_settings', $site_settings);
Add to
app->Providers->AppServiceProvider file boot method
it's global variable.
Most popular answers here with BaseController didn't worked for me on Laravel 5.4, but they have worked on 5.3. No idea why.
I have found a way which works on Laravel 5.4 and gives variables even for views which are skipping controllers. And, of course, you can get variables from the database.
add in your app/Providers/AppServiceProvider.php
class AppServiceProvider extends ServiceProvider
{
public function boot()
{
// Using view composer to set following variables globally
view()->composer('*',function($view) {
$view->with('user', Auth::user());
$view->with('social', Social::all());
// if you need to access in controller and views:
Config::set('something', $something);
});
}
}

In Laravel 5+, to set a variable just once and access it 'globally', I find it easiest to just add it as an attribute to the Request:
$request->attributes->add(['myVar' => $myVar]);
Then you can access it from any of your controllers using:
$myVar = $request->get('myVar');
and from any of your blades using:
{{ Request::get('myVar') }}
In Laravel 5.1 I needed a global variable populated with model data accessible in all views.
I followed a similar approach to ollieread's answer and was able to use my variable ($notifications) in any view.
My controller location: /app/Http/Controllers/Controller.php
<?php
namespace App\Http\Controllers;
use Illuminate\Foundation\Bus\DispatchesJobs;
use Illuminate\Routing\Controller as BaseController;
use Illuminate\Foundation\Validation\ValidatesRequests;
use Illuminate\Foundation\Auth\Access\AuthorizesRequests;
use App\Models\Main as MainModel;
use View;
abstract class Controller extends BaseController
{
use AuthorizesRequests, DispatchesJobs, ValidatesRequests;
public function __construct() {
$oMainM = new MainModel;
$notifications = $oMainM->get_notifications();
View::share('notifications', $notifications);
}
}
My model location: /app/Models/Main.php
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
use DB;
class Main extends Model
{
public function get_notifications() {...
I have found a better way which works on Laravel 5.5 and makes variables accessible by views. And you can retrieve data from the database, do your logic by importing your Model just as you would in your controller.
The "*" means you are referencing all views, if you research more you can choose views to affect.
add in your app/Providers/AppServiceProvider.php
<?php
namespace App\Providers;
use Illuminate\Contracts\View\View;
use Illuminate\Support\ServiceProvider;
use App\Setting;
class AppServiceProvider extends ServiceProvider
{
/**
* Bootstrap any application services.
*
* #return void
*/
public function boot()
{
// Fetch the Site Settings object
view()->composer('*', function(View $view) {
$site_settings = Setting::all();
$view->with('site_settings', $site_settings);
});
}
/**
* Register any application services.
*
* #return void
*/
public function register()
{
}
}
If you are worried about repeated database access, make sure that you have some kind of caching built into your method so that database calls are only made once per page request.
Something like (simplified example):
class Settings {
static protected $all;
static public function cachedAll() {
if (empty(self::$all)) {
self::$all = self::all();
}
return self::$all;
}
}
Then you would access Settings::cachedAll() instead of all() and this would only make one database call per page request. Subsequent calls will use the already-retrieved contents cached in the class variable.
The above example is super simple, and uses an in-memory cache so it only lasts for the single request. If you wanted to, you could use Laravel's caching (using Redis or Memcached) to persist your settings across multiple requests. You can read more about the very simple caching options here:
http://laravel.com/docs/cache
For example you could add a method to your Settings model that looks like:
static public function getSettings() {
$settings = Cache::remember('settings', 60, function() {
return Settings::all();
});
return $settings;
}
This would only make a database call every 60 minutes otherwise it would return the cached value whenever you call Settings::getSettings().
You can also use Laravel helper which I'm using.
Just create Helpers folder under App folder
then add the following code:
namespace App\Helpers;
Use SettingModel;
class SiteHelper
{
public static function settings()
{
if(null !== session('settings')){
$settings = session('settings');
}else{
$settings = SettingModel::all();
session(['settings' => $settings]);
}
return $settings;
}
}
then add it on you config > app.php under alliases
'aliases' => [
....
'Site' => App\Helpers\SiteHelper::class,
]
1. To Use in Controller
use Site;
class SettingsController extends Controller
{
public function index()
{
$settings = Site::settings();
return $settings;
}
}
2. To Use in View:
Site::settings()
A global variable for using in controllers; you can set in AppServiceProvider like this :
public function boot()
{
$company=DB::table('company')->where('id',1)->first();
config(['yourconfig.company' => $company]);
}
usage
config('yourconfig.company');
using middlwares
1- create middlware with any name
<?php
namespace App\Http\Middleware;
use Closure;
use Illuminate\Support\Facades\View;
class GlobalData
{
public function handle($request, Closure $next)
{
// edit this section and share what do you want
$site_settings = Setting::all();
View::share('site_settings', $site_settings);
return $next($request);
}
}
2- register your middleware in Kernal.php
protected $routeMiddleware = [
.
...
'globaldata' => GlobalData::class,
]
3-now group your routes with globaldata middleware
Route::group(['middleware' => ['globaldata']], function () {
// add routes that need to site_settings
}
In file - \vendor\autoload.php, define your gobals variable as follows, should be in the topmost line.
$global_variable = "Some value";//the global variable
Access that global variable anywhere as :-
$GLOBALS['global_variable'];
Enjoy :)
I know I am super late to the party, but this was the easiest way I found.
In app/Providers/AppServiceProvider.php, add your variables in the boot method. Here I am retrieving all countries from the DB:
public function boot()
{
// Global variables
view()->composer('*',function($view) {
$view->with('countries', Country::all());
});
}
There are two options:
Create a php class file inside app/libraries/YourClassFile.php
a. Any function you create in it would be easily accessible in all the views and controllers.
b. If it is a static function you can easily access it by the class name.
c. Make sure you inclued "app/libraries" in autoload classmap in composer file.
In app/config/app.php create a variable and you can reference the same using
Config::get('variable_name');
Hope this helps.
Edit 1:
Example for my 1st point:
// app/libraries/DefaultFunctions.php
class DefaultFunctions{
public static function getSomeValue(){
// Fetch the Site Settings object
$site_settings = Setting::all();
return $site_settings;
}
}
//composer.json
"autoload": {
"classmap": [
..
..
..
"app/libraries" // add the libraries to access globaly.
]
}
//YourController.php
$default_functions = new DefaultFunctions();
$default_functions->getSomeValue();
