04. Routes

Methods

For web: routes/web.php:

Route::get('/', function () {
    return view('welcome');
});

Route::post('/send-email', function () {
    return view('contact-us');
});

All available router methods:

Route::get($uri, $callback);
Route::post($uri, $callback);
Route::put($uri, $callback);
Route::patch($uri, $callback);
Route::delete($uri, $callback);
Route::options($uri, $callback);

Several methods at once:

Route::match(['get', 'post'], '/about', function () {
    return view('welcome');
});

Any method:

Route::any('/about', function () {
    return view('welcome');
});

Without a closure

Route::view('/hello', 'about-us', ['name' => 'Andrew']);

Names for routes

Route::get('/', function () {
    return view('welcome');
})->name('home');

No we can use it in the route() function:

{{ route('home') }}

Redirect

Route::redirect('/about', '/contact'); // default status = 302
## Permanent redirect:
Route::redirect('/about', '/contact', 301); // default status = 301
Route:permanentRedirect('/about', '/contact');

Parameters

Parameters are positioned (we can name them like we want, only the order matters).

Route::get('/post/{id}', function($id) {
    return "Post $id";
});

Route::get('/post/{id}/{slug}', function($id, $slug) {
    return "Post $id";
});

Make a parameter optional:

Route::get('/post/{id}/{slug?}', function($id, $slug = null) {
    return "Post $id";
});

Filters:

Route::get('/post/{id}/{slug}', function($id, $slug) {
    return "Post $id";
})->where('id', '[0-9]+');

Route::get('/post/{id}/{slug}', function($id, $slug) {
    return "Post $id";
})->where([
    'id'    => '[0-9]+',
    'slug'  => '[A-Za-z0-9-]+',
]);

Global filters (in app/Providers/RouteServiceProvider.php):

public function boot() {
    Route::pattern('id', '[0-9]+');
    Route::pattern('slug','[A-Za-z0-9-]+');
...

Chaning how a parameter named in a resource:

Route::resource('/posts', 'PostController', [
    'parameters' => ['posts' => 'id'],
]);

Grouping URLs

Route::prefix('admin')->group(function () {

    Route::get('/posts', function () {
        return 'Posts List';
    });

    Route::get('/post/create', function () {
        return 'Post Create';
    });

    Route::get('/post/{id}/edit', function ($id) {
        return "Edit Post $id";
    });
});

Render a view

Function view() looks for a view file in resources/views/, for example:

resources/views/welcome.blade.php

Passing variables:

Route::get('/', function () {
    return view('welcome', [
        'name' => 'Andrew',
    ]);
});

Route::get('/', function () {
    return view('welcome')->with('name', 'Andrew');
});

Getting a route URL

Route::get('/', function () {
    return view('welcome');
})->name('home');

route('home')

If a route has parameters:

route('home', ['id' => 1, 'name' => 'Andrew'])

Group with a name:

Route::prefix('admin')->name('admin.')->group(function () {
    Route::get('welcome', function () {
        return "Welcome";
    })->name('welcome');
});

## route URL:
route('admin.welcome')

Route for absent URLs:

Route::fallback(function() {
    return redirect()->route('home');
});

Abort function:

Route::fallback(function() {
    abort(404, 'Oops! Page not found.');
});

In this case views should be in resources/views/errors/404.blade.php

<h1>{{ $exceptions->getMessage() }}</h1>

Calling controllers

Route::get('/', 'HomeController@index');

Route::get('/', 'Admin\PostController@index');

Resource controllers:

Route::resource('/photos', 'PhotoController');
