lecture 2 Routing

Routing - Basic Routing

	Route::get('foo', function () {
    return 'Hello World';
    });

Routing 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);

Routing View Routes

    Route::view('/welcome', 'welcome');

    Route::view('/welcome', 'welcome', ['name' => 'Taylor']);

Routing Parameters

Required Parameters

    Route::get('posts/{post}/comments/{comment}', function ($postId, $commentId) {
        //
    });

Optional Parameters

	Route::get('user/{name?}', function ($name = null) {
    return $name;
    });

    Route::get('user/{name?}', function ($name = 'John') {
        return $name;
    });

Routing Regular Expression Constraints

    Route::get('user/{name}', function ($name) {
        //
    })->where('name', '[A-Za-z]+');

    Route::get('user/{id}', function ($id) {
        //
    })->where('id', '[0-9]+');

    Route::get('user/{id}/{name}', function ($id, $name) {
        //
    })->where(['id' => '[0-9]+', 'name' => '[a-z]+']);

Global Constraints

define these patterns in the boot method of your RouteServiceProvider:
```php
/**
* Define your route model bindings, pattern filters, etc.
*
* @return void
*/
public function boot()
{
    Route::pattern('id', '[0-9]+');

    parent::boot();
}
```

Routing Named Routes

    Route::get('user/profile', function () {
        //
    })->name('profile');

    Route::get('user/profile', 'UserProfileController@show')->name('profile');

Generating URLs To Named Routes

  // Generating URLs...
  $url = route('profile');

  // Generating Redirects...
  return redirect()->route('profile');

# If you want to Show  route:list :
  > 	php artisan route:list

  > 	php artisan make:controller EmpController

Route::resource('emps', 'EmpController');
