FuelPHP series (2) ------ route routing

In FuelPHP, it can be accessed through /controller_name/function_name by default, or through custom routes.

Routes are configured in the /fuel/app/config/routes.php file.

First, the simplest routing settings, in the form of key-value pairs.

　　return array(
    　　'article'   => 'article/index',
    　　'article/add' => 'article/create',
    　　'article/edit'   => 'article/edit',
　　);

　　The key name is the content entered in the URL, and the corresponding value is the method in the requested controller.

2. Add some rules to the routing

`:any`	Can match any character, but cannot be empty
`:everything`	matches any character
`:segment`	matches a part of the URL, which can be any character,
`:num`	match any number
:alpha	match greek letters
`:alnum`	matches any letter and number

　　return array(
    　　'article/(:any)'          => 'article/indexxxxx', 
    　　'article(:everything)'    => 'article/add',
    　　'(:segment)/article'      => 'test/article',
　　　　'(:segment)article'        => 'test1/article',
    　　'(\d{2})/item' => 'site2/item', 
　　);
　　　　'blog/:year/:month/:id'    => 'blog/entry',

3. According to different request methods, there are GET, POST, DELETE and so on to route the URL to the controller.

　　return array(
    　　'blog' => array(array('GET', new Route('blog/all')), array('POST', new Route('blog/create'))),
　　　　'blog/(:any)' => array(array('GET', new Route('blog/show/$1'), true)),
　　);

　　This can also be used in conjunction with the rules above.

Fourth, set up a route with a name

　　return array(
    　　'admin/start/overview' => array('admin/overview', 'name' => 'admin_overview'),
　　);

　　In the static page, you can use the route name to realize the click jump

　　echo Html::anchor(Router::get('admin_overview'), 'Overview');

　　<a href="{Router::get('admin_overview')}">Overview</a>

5. The Route class in the core directory

　　1. add( $path , $options = null , $prepend = false , $case_sensitive = null ) to add a route

　　　　The method of the controller the $path route points to

　　　　Parameters in the $options route

　　　　$prepend true route prepares already loaded routes

　　　　$case_sensitive is case sensitive

　　Router::add('this/that', 'something/else');　　// similar to a simple key-value pair in one

　　2. get( $name , $named_params = array ()) Get the route through the defined route name

　　　　$name the defined route name

　　　　$named_params route parameters

　　//1、
　　return array(
    　　'thread/(?P<thread_id>\d+?)/post' => array('post', 'name' => 'post'),
　　);

　　// Based on the routes defined above, the following will return 'thread/1/post': 
　　echo Router::get('post', array ('thread_id' => 1 ));
　　echo Router::get('post' , array ('$1' => 1 ));
　　echo Router::get('post', array (1 ));

　　//2、
　　return array(
    　　'country/(?P<country>\d+?)/state/(?P<state>\d+?)/location' => array('location', 'name' => 'location'),
　　);

　　// Based on the routes defined above, the following will return 'country/japan/state/tokyo/location': 
　　echo Router::get('location', array ('country' => 'japan', 'state' => 'tokyo' ));
　　echo Router::get('location', array ('$1' => 'japan', '$2' => 'tokyo' ));
　　echo Router::get('location', array ( 'japan', 'tokyo' ));
　　echo Router::get('location', array ('country' => 'japan', 'tokyo' ));
　　echo Router::get('location', array (' $1' =>'japan', 'tokyo'));

　　3. delete( $path , $case_sensitive = null ) delete the defined route

　　　　$path route URL

　　　　$case_sensitive is case sensitive

　　// delete route 'this/that' 
　　Router::delete('this/that' );

　　// 删除路由 'this/that' 和'some/other'
　　Router::delete(array('this/that', 'some/other'));

　　// Set routing case sensitive 
　　Router::delete('this/that', true );

　　// Delete all routes of the module controller 
　　Router::delete('module/controller(:any)');

return array(
    'about'   => 'site/about',
    'contact' => 'contact/form',
    'admin'   => 'admin/login',
);
