[Laravel4] Routing examples

There is some sample code example recorded for an reference only. Let use my case as an example, there is the default root page if I set nothing

http://localhost/laravel4.2/foldername/public/

------------------------
Sample 1) simple  route

Route::get('/', function(){
    return "All dogs";
});

If http://localhost/laravel4.2/foldername/public/ (root page), the root page display text “All dogs only”

 ------------------------
Sample 2) with route parameters

Route::get('cats/{id}', function($id){
    return "Cat #$id";
});

If visiting "http://localhost/laravel4.2/foldername/public/cats/123", text “Cat#123” shown

  ------------------------
Sample 3) route with route parameters and condition

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

If visiting http://localhost/laravel4.2/foldername/public/cats/123, shown text “Cat#123” :


However, if you visit the url where parameters aren’t in number: (for e.g: http://localhost/laravel4.2/foldername/public/cats/abc) , would display 404 errors page:

------------------------
Sample 4) redirect with route

Route::get('/', function(){
    return "All dogs";
});
Route::get('/dogs', function(){
    return Redirect::to('/');
});

If visiting the page http://localhost/laravel4.2/foldername/public/dogs, it would redirect you to http://localhost/laravel4.2/foldername/public/


------------------------
Sample 5) Returning views

Route::get('welcome', function(){
return View::make('hello');
});

This sample is for returning view but not the text only, in this sample used the default hello view (at app\views\hello.php) provided by Laravel framework.
if you entering the "http://localhost/laravel4.2/foldername/public/welcome", the screen shows this page:

------------------------
Sample 6) Returning views with data

Create a php file named “about.php” at “/app/views” directory and add these code:

<h2>About this site</h2>

There are <?php echo $number_of_dogs; ?> dogs on this site.

And then add code at route :

Route::get('about', function(){

return View::make('about')->with('number_of_dogs', 500);

});

When visit the uri : http://localhost/laravel4.2/foldername/public/about, you would see content of the view “about.php” and also the number_of_dogs valuable defined at route.php

------------------------
Sample 7) Returning views with data 2 (data from url)
This is an example returning a view and shows numbers from url params:

Route::get('about_params/{num_of_dogs}', function($num_of_dogs){
    return View::make('about')->with('number_of_dogs', $num_of_dogs);
})->where('id','[0-9]+');
