'How to pass data to all views in Laravel 5?

I want to have some default data accessible in all views in my Laravel 5 application.

I have tried to search for it but only find results for Laravel 4. I have read the documentation 'Sharing Data With All Views' here but I can't understand what to do. Where should the following code be placed?

View::share('data', [1, 2, 3]);

Thanks for your help.

Solution 1:^[1]

This target can achieve through different method,

1. Using BaseController

The way I like to set things up, I make a BaseController class that extends Laravel’s own Controller, and set up various global things there. All other controllers then extend from BaseController rather than Laravel’s Controller.

class BaseController extends Controller
{
  public function __construct()
  {
    //its just a dummy data object.
    $user = User::all();

    // Sharing is caring
    View::share('user', $user);
  }
}

2. Using Filter

If you know for a fact that you want something set up for views on every request throughout the entire application, you can also do it via a filter that runs before the request — this is how I deal with the User object in Laravel.

App::before(function($request)
{
  // Set up global user object for views
  View::share('user', User::all());
});

You can define your own filter

Route::filter('user-filter', function() {
    View::share('user', User::all());
});

and call it through simple filter calling.

Update According to Version 5.*

3. Using Middleware

Using the View::share with middleware

Route::group(['middleware' => 'SomeMiddleware'], function(){
  // routes
});



class SomeMiddleware {
  public function handle($request)
  {
    \View::share('user', auth()->user());
  }
}

4. Using View Composer

View Composer also help to bind specific data to view in different ways. You can directly bind variable to specific view or to all views. For Example you can create your own directory to store your view composer file according to requirement. and these view composer file through Service provide interact with view.

View composer method can use different way, First example can look alike:

You could create an App\Http\ViewComposers directory.

Service Provider

namespace App\Providers;
use Illuminate\Support\ServiceProvider;
class ViewComposerServiceProvider extends ServiceProvider {
    public function boot() {
        view()->composer("ViewName","App\Http\ViewComposers\TestViewComposer");
    }
}

After that, add this provider to config/app.php under "providers" section.

TestViewComposer

namespace App\Http\ViewComposers;

use Illuminate\Contracts\View\View;

class TestViewComposer {

    public function compose(View $view) {
        $view->with('ViewComposerTestVariable', "Calling with View Composer Provider");
    }
}

ViewName.blade.php

Here you are... {{$ViewComposerTestVariable}}

This method could help for only specific View. But if you want trigger ViewComposer to all views, we have to apply this single change to ServiceProvider.

namespace App\Providers;
use Illuminate\Support\ServiceProvider;
class ViewComposerServiceProvider extends ServiceProvider {
    public function boot() {
        view()->composer('*',"App\Http\ViewComposers\TestViewComposer");
    }
}

Solution 2:^[2]

You can either create your own service provider (ViewServiceProvider name is common) or you can use the existing AppServiceProvider.

In your selected provider, put your code in the boot method.

public function boot() {
    view()->share('data', [1, 2, 3]);
}

This will make a $data variable accessible in all your views.

If you rather want to use the facade instead of the helper, change view()-> to View:: but don't forget to have use View; at the top of your file.

Solution 3:^[3]

I found this to be the easiest one. Create a new provider and user the '*' wildcard to attach it to all views. Works in 5.3 as well :-)

<?php

namespace App\Providers;

use Illuminate\Http\Request;
use Illuminate\Support\ServiceProvider;

class ViewServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap the application services.
     * @return void
     */
    public function boot()
    {
        view()->composer('*', function ($view)
        {
            $user = request()->user();

            $view->with('user', $user);
        });
    }

    /**
     * Register the application services.
     *
     * @return void
     */
    public function register()
    {
        //
    }
}

Solution 4:^[4]

The best way would be sharing the variable using View::share('var', $value);

Problems with composing using "*":

Consider following approach:

<?php
// from AppServiceProvider::boot()
$viewFactory = $this->app->make(Factory::class);

$viewFacrory->compose('*', GlobalComposer::class);

From an example blade view:

  @for($i = 0; $i<1000; $i++)
    @include('some_partial_view_to_display_i', ['toDisplay' => $i])
  @endfor

What happens?

The GlobalComposer class is instantiated 1000 times using App::make.
The event composing:some_partial_view_to_display_i is handled 1000 times.
The compose function inside the GlobalComposer class is called 1000 times.

But the partial view some_partial_view_to_display_i has nothing to do with the variables composed by GlobalComposer but heavily increases render time.

Best approach?

Using View::share along a grouped middleware.

Route::group(['middleware' => 'WebMiddleware'], function(){
  // Web routes
});

Route::group(['prefix' => 'api'], function (){

});

class WebMiddleware {
  public function handle($request)
  {
    \View::share('user', auth()->user());
  }
}

Update

If you are using something that is computed over the middleware pipeline you can simply listen to the proper event or put the view share middleware at the last bottom of the pipeline.

Solution 5:^[5]

In the documentation:

Typically, you would place calls to the share method within a service provider's boot method. You are free to add them to the AppServiceProvider or generate a separate service provider to house them.

I'm agree with Marwelln, just put it in AppServiceProvider in the boot function:

public function boot() {
    View::share('youVarName', [1, 2, 3]);
}

I recommend use an specific name for the variable, to avoid confussions or mistakes with other no 'global' variables.

The documentation is hear https://laravel.com/docs/5.4/views#view-composers but i will break it down

Look for the directory app\Providers in the root directory of your application and create the file ComposerServiceProvider.php and copy and past the text below into it and save it.

<?php
    namespace App\Providers;
    use Illuminate\Support\Facades\View;
    use Illuminate\Support\ServiceProvider;

    class ComposerServiceProvider extends ServiceProvider
    {
        /**
        * Register bindings in the container.
        *
        * @return void
        */
    public function boot()
    {
        // Using class based composers...
        View::composer(
            'profile', 'App\Http\ViewComposers\ProfileComposer'
        );

        // Using Closure based composers...
        View::composer('dashboard', function ($view) {
            //
        });
    }

    /**
    * Register the service provider.
    *
    * @return void
    */
    public function register()
    {
        //
    }
}

From the root of your application open Config/app.php and look for the Providers section in the file and copy and past this 'App\Providers\ComposerServiceProvider', to the array.

By doing this, we have created the Composer Service Provider. When you run your application with the view Profile like so http://yourdomain/something/profile, the service provider ComposerServiceProvider is called and the class App\Http\ViewComposers\ProfileComposer is instantiated calling the method Composer due to the code below inside the boot method or function.

 // Using class based composers...
 View::composer(
   'profile', 'App\Http\ViewComposers\ProfileComposer'
 );

If you refresh your application you will get an error because the class App\Http\ViewComposers\ProfileComposer does not exist yet. Now lets create it.

Go to the directory path app/Http

Create the directory called ViewComposers

Create the file ProfileComposer.php.

class ProfileComposer
{
    /**
    * The user repository implementation.
    *
    * @var UserRepository
    */
    protected $users;

    /**
    * Create a new profile composer.
    *
    * @param  UserRepository  $users
    * @return void
    */
    public function __construct(UserRepository $users)
    {
        // Dependencies automatically resolved by service container...
        $this->users = $users;
    }

    /**
    * Bind data to the view.
    *
    * @param  View  $view
    * @return void
    */
    public function compose(View $view)
    {
        $view->with('count', $this->users->count());
    }
}

Now go to your view or in this case Profile.blade.php and add

{{ $count }}

and that will show the count of users on the profile page.

To show the count on all pages change

// Using class based composers...
View::composer(
    'profile', 'App\Http\ViewComposers\ProfileComposer'
);

// Using class based composers...
View::composer(
    '*', 'App\Http\ViewComposers\ProfileComposer'
);

Solution 7:^[7]

You have two options:

1. Share via ?Boot function in App\Providers\AppServiceProvider:

public function boot()
{
  view()->share('key', 'value');
}

And access $key variable in any view file.

Note: Remember that you can't access current Session, Auth, Route data here. This option is good only if you want to share static data. Suppose you want to share some data based on the current user , route, or any custom session variable you won't be able to do with this.

2. Use of a helper class:

Create a helper class anywhere in your application and register it in Alias array in app.php file in config folder.

 'aliases' => [ 
   ...,
  'Helper' => App\HelperClass\Helper::class,
 ],

and create Helper.php in HelperClass folder within App folder:

namespace App\HelperClass;
    
class Helper
{
    public static function Sample()
    {
        //Your Code Here
    }
}

and access it anywhere like Helper::Sample().

You will not be restricted here to use Auth, Route, Session, or any other classes.

I think that the best way is with View Composers. If someone came here and want to find how can do it with View Composers way, read my answer => How to share a variable across all views?

Solution 9:^[9]

The documentation is here https://laravel.com/docs/5.4/views#view-composers but i will break it down 1.Look for the directory Providers in your root directory and create the for ComposerServiceProvider.php with content

Solution 10:^[10]

Inside your config folder you can create a php file name it for example "variable.php" with content below:

<?php

  return [
    'versionNumber' => '122231',
  ];

Now inside all the views you can use it like

config('variable.versionNumber')

Solution 11:^[11]

1) In (app\Providers\AppServiceProvider.php)

// in boot function
       view()->composer('*', function ($view) {
            $data = User::messages();
            $view->with('var_messages',$data);
        });

2) in Your User Model

  public static function messages(){ // this is just example
        $my_id = auth()->user()->id;
        $data= Message::whereTo($my_id)->whereIs_read('0')->get(); 
        return $data; // return is required
    }

3) in Your View

 {{ $var_messages }}

Solution 12:^[12]

Laravel 5.6 method: https://laravel.com/docs/5.6/views#passing-data-to-views

Example, with sharing a model collection to all views (AppServiceProvider.php):

use Illuminate\Support\Facades\View;
use App\Product;

public function boot()
{
    $products = Product::all();
    View::share('products', $products);

}

Solution 13:^[13]

for example you can return list of all tables in database to the all views of Controller like this :

public function __construct()
{
    $tables = DB::select('SHOW TABLES'); // returns an array of stdObjects
    view()->share('tables', $tables);
}

Solution 14:^[14]

In Laravel 5 and above versions , you can edit boot function in AppServiceProvider.php to access variable in all views

public function boot()
{
    \View::composer('*', function($view){
        $view->with('key', 'value');
    });
}

"Key" represents the name of the variable which you want to set, so that you can use it later in any .blade.php file and "value" represents the value represented by the variable... For Example :

//setting user role to be accessed by all blade.php files

public function boot(){
//
View::composer('*', function($view){
view->with('role', Auth::user()->infouser->role);
 });
}

Solution 15:^[15]

If are you using Laravel 8 you can do this like that,

class Controller extends BaseController{
use AuthorizesRequests, DispatchesJobs, ValidatesRequests;

public function __construct(){
    $categories = Category::where('show_menu', '=', 1)->where('status', '=', 'approved')->get();
    view()->share('categories', $categories);
}}
