Laravel 4 basic routing reference
Please note that this is not tutorial. I'm treating this article as quick reference for myself.
Creating routes in Laravel is quite easy, just open app/routes.php and start writting in here is quick reference on the ways to get started, it's by no means comprehensive guide to Laravel routing, but just quick reference for myself. If you want full blown guide into routing please check Laravel docs.
The simplest route possible will be:
Route::get('/', function(){
return "hello world!";
});
The first parameter is where one would define route in this case it's the root of the app, if the app is hosted under example.com domain it would be accessed by http://www.example.com/, the second parameter in this case is closure which processes route and returns string `hello world!`.
To pass parameter to route one would use following syntax in the first Route::get argument: '/foo/{bar}', to pass optional parameter one could pass '/foo/{bar?}' to work with arguments you need to pass them to closure like this function($bar), if the parameter is optional you can define default parameter like this function($bar = "baz"). So the final route will look like this:
Route::get('/foo/{bar?}', function($bar = "baz")
{
return "hello {$baz}";
});
There is one more thing regarding passing parameters to route one can supply regex for route parameter matching:
Route::get('/foo/{bar}', function($bar){})->where('bar', '[A-Za-z]+');
//multiple param pattern matching is done by chaining where():
Route::get()->where('p1', 'pattern')->where('p2', 'pattern');
you can also give alias to controller using following syntax:
Route::get('/', ['as'=>'home',function]);
One can also attach routes to controllers in the following manner:
// attach to non-namespaced controller method:
Route::get('/foo', 'barController@baz');
// attach to namespaced controller method:
Route::get('/foo', 'my\namespace'barController@baz');
// attach controller to route also add alias:
Route::get('/foo', ['as' => 'bar', 'uses' => 'fooController@baz']);
There is much more to cover regarding routing such as filtering returning views etc. But as I said I'm treating this article as quick reminder to myself. I will continue covering laravel basics. As I will get more grasp on them.
