- Sharing Data with all Views
Understanding Views
Views (or Templates) in Laravel are stored in the "resources/views" directory. They are '.php' files that describe how some output should look, and can contain HTML, CSS, JavaScript, and PHP content.In Laravel, there are two formats of view you can use: Blade (with ".blade.php" extension in file name) rendered with the Blade engine; or simple ".php" (which will not parse the Blade Template statements).
- Example of a simple Blade view:
1. Copy the following code and save it in a resources/views/light.blade.php file.
<html> <body> <h1>View is an effect, Vision is the source</h1> </body> </html>2. Add the following line in routes/web.php file to set the route for the above view.
Route::get('/light', function(){
return view('light');
});
3. Visit the following URL to see the output of the view.
//localhost:8000/light
- The output will appear as shown in the following image.
If the view file is into a sub-folder in "resources/views" directory, for example "resources/views/pages/name.blade.php", add the sub-folder name before file name:
return view('pages.name');
If you need to determine if a view exists, you may use the exists() method of the View facade. The method return true if the view exists:
use Illuminate\Support\Facades\View;
if(View::exists('pages.test')){
//
}
Passing Data to Views
You can use variables in the view template file, with this syntax: {{$variable_name}} , then pass an array with key/value pairs as a second argument in the view() method.The "key" in array must be the same as the name of the variable in template.
- Example of a simple Blade view:
1. Copy the following code and save it in a resources/views/greeting.blade.php file.
<html>
<head>
<title>{{$title}}</title>
</head>
<body>
<h1>Hello {{$name}}</h1>
</body>
</html>
2. Add the following line in routes/web.php file to set the route for the above view.
Route::get('/greeting', function(){
$vars =['title'=>'Greetings', 'name'=>'Me'];
return view('greeting', $vars);
});
3. Visit the following URL to see the output of the view.
//localhost:8000/greeting
- The output will appear as shown in the following image.
Sharing Data with all Views
If you want to pass same data to all the views, use the view()->share() method.The share() method will take two arguments: key and value.
Typically share() method can be called from boot() method of service provider.
We can use any service provider, like: AppServiceProvider or our own service provider.
- Example:
1. Create two view files: test.blade.php and test2.blade.php with the same code, in the "resources/views/" directory.
- Copy the following code in both the files.
<html>
<body>
<h1>Share {{$state}}</h1>
<h2>Receive {{$gift}}</h2>
</body>
</html>
2. Change the code of boot() method in the file app/Providers/AppServiceProvider.php as shown below. (Here, we have used the share() method, and the data that we have added will be shared with all the views).
<?php
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
class AppServiceProvider extends ServiceProvider {
//Bootstrap any application services.
//@return void
public function boot(){
view()->share('state', 'Peace');
view()->share('gift', 'Love');
}
//Register any application services.
//@return void
public function register(){
//
}
}
3. Add the following lines in routes/web.php file.
Route::get('/test', function(){
return view('test');
});
Route::get('/test2', function(){
return view('test2');
});
4. Visit the following URLs:
//localhost:8000/test //localhost:8000/test2- The output for both URLs will appear as shown in the following image.
