Routing in Laravel
Hello everyone, welcome to justlaravel.com. Here we ‘ll see about routing in laravel. All laravel routes are defined in routes.php file (located at app/Http/routes.php).
Routing is very simple, clear and one of the coolest features in laravel, we can see all the pages, where they are linked in a single place.

We will see 4 different types of routing,
- Route returning a view
- Route returning some static text
- Routing to a controller which returns a view
- Routing to a controller which returns data from database and renders in a view
Route returning a view:
When we open routes.php file, we can see a default route which returns a view, it looks like the snippet below,
Route::get ( '/', function () {
return view ( 'welcome' );
} );
when we open the browser and type localhost:8000/, it returns the default view named ‘welcome’
Route returning some static text:
We ‘ll define another simple route to display some sample text when that particular route is called,
Route::get ( '/hello', function () {
return 'Hello World!';
} );
When we open the browser and type localhost:8000/hello, it will return the text ‘Hello World!’ we just gave,
Routing to a controller which returns a view:
We ‘ll define one more route, this time it calls the controller, and that controller simply returns a view,
Route::get ( '/callController', 'IndexController@index' );
The controller logic for index function would be,
public function index() {
return view ( 'welcome' );
}
When we open the browser, and type localhost:8000/callController, it returns the default view named ‘Welcome’
Routing to a controller which returns data from the database and renders in a view:
We ‘ll define another route, it calls the controller, and this controller interacts with model and collects some data from the database, now we ‘ll render that obtained data in the view,
Route::get ( '/callControllerDb', 'IndexController@getFromDb');
The controller logic for getFromDb function would be,
public function getFromDb() {
$users = User::all();
return view('sample')->withDetails($users);
}
the view file, sample.blade.php would be,
<!DOCTYPE html>
<html lang="en">

@foreach($details as $user)
<tr>
<td>{{$user->name}}</td>
<td>{{$user->email}}</td>
</tr>
@endforeach

When we open the browser and type, localhost:8000/callControllerDb, it calls to index controller, which gets data from the database and renders it in the view,

Thank you for such an easy implementation of the search function! My function displays results fine, however, when the search returns no results, the redirect to a different page works, but the message does not show. Any suggestions?
Did you redirect it with a message.
thanks for the amazing explanation, the foreach duplicate the value.
when i run this code in my code, not for user for a search result
@foreach($details as $user)
{{$user->name}}
{{$user->email}}
@endforeach
it appears as three duplicated rows.
