How to pass data to all views in Laravel 5?

Question

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.

Answer 1

The documentation is hear 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

Answer 2

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()
    {
        //
    }
}

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.

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

1. 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()
       {
           //
       }
   }
   

2. 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'
 );

3. 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'
);

To

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