In MVC framework, the letter “V” stands for Views. It separates the application logic and the presentation logic. Views are stored in resources/views directory. Generally, the view contains the HTML which will be served by the application.
Example
Observe the following example to understand more about Views −
Step 1 − Copy the following code and save it at resources/views/test.php
<html> <body> <h1>Hello, World</h1> </body> </html>
Step 2 − Add the following line in app/Http/routes.php file to set the route for the above view.
app/Http/routes.php
Route::get('/test', function() {
return view('test');
});
Step 3 − Visit the following URL to see the output of the view.
http://localhost:8000/test
Step 4 − The output will appear as shown in the following image.
Passing Data to Views
While building application it may be required to pass data to the views. Pass an array to view helper function. After passing an array, we can use the key to get the value of that key in the HTML file.
Example
Observe the following example to understand more about passing data to views −
Step 1 − Copy the following code and save it at resources/views/test.php
<html> <body> <h1><?php echo $name; ?></h1> </body> </html>
Step 2 − Add the following line in app/Http/routes.php file to set the route for the above view.
app/Http/routes.php
Route::get('/test', function() {
return view('test',[‘name’=>’Virat Gandhi’]);
});
Step 3 − The value of the key name will be passed to test.php file and $name will be replaced by that value.
Step 4 − Visit the following URL to see the output of the view.
http://localhost:8000/test
Step 5 − The output will appear as shown in the following image.
Sharing Data with all Views
We have seen how we can pass data to views but at times, there is a need to pass data to all the views. Laravel makes this simpler. There is a method called share() which can be used for this purpose. 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, AppServiceProvider or our own service provider.
Example
Observe the following example to understand more about sharing data with all views −
Step 1 − Add the following line in app/Http/routes.php file.
app/Http/routes.php
Route::get('/test', function() {
return view('test');
});
Route::get('/test2', function() {
return view('test2');
});
Step 2 − Create two view files — test.php and test2.php with the same code. These are the two files which will share data. Copy the following code in both the files. resources/views/test.php & resources/views/test2.php
<html> <body> <h1><?php echo $name; ?></h1> </body> </html>
Step 3 − Change the code of boot method in the file app/Providers/AppServiceProvider.php as shown below. (Here, we have used share method and the data that we have passed will be shared with all the views.) app/Providers/AppServiceProvider.php
<?php namespace App\Providers; use Illuminate\Support\ServiceProvider; class AppServiceProvider extends ServiceProvider { /** * Bootstrap any application services. * * @return void */ public function boot() { view()->share('name', 'Virat Gandhi'); } /** * Register any application services. * * @return void */ public function register() { // } }
Step 4 − Visit the following URLs.
http://localhost:8000/test http://localhost:8000/test2
Step 5 − The output will appear as shown in the following image.
