Hi, first sorry for the late reply, but I am on vacations and offline most
of the time.
Here is an example on how we use the Yii2 framework router:
'urlManager' => [
'class' => \frontend\components\UrlManager::className(),
'enablePrettyUrl' => true,
'showScriptName' => false,
// 'suffix' => '.daxs',
'rules' => [
//contact
['pattern' => 'contact', 'route' => '/site/contact/',
'defaults' => ['lang' => 'en-US']],
['pattern' => 'contactarme', 'route' => '/site/contact/',
'defaults' => ['lang' => 'es']],
//about
['pattern' => 'en/about', 'route' => '/blog/post/view/',
'defaults' => ['lang' => 'en-US', 'postSlug' => 'about']],
['pattern' => 'es/acerca-de', 'route' =>
'/blog/post/view/', 'defaults' => ['lang' => 'es', 'postSlug' =>
'acerca-de']],
//curriculum
['pattern' => 'en/curriculum', 'route' =>
'/blog/post/view/', 'defaults' => ['lang' => 'en-US', 'postSlug' =>
'curriculum-2']],
['pattern' => 'es/curriculum', 'route' =>
'/blog/post/view/', 'defaults' => ['lang' => 'es', 'postSlug' =>
'curriculum']],
//feed
['pattern' => 'en/feed', 'route' => '/blog/post/feed',
'defaults' => ['lang' => 'en-US'], 'suffix' => ".xml"],
['pattern' => 'es/canal', 'route' => '/blog/post/feed',
'defaults' => ['lang' => 'es'], 'suffix' => ".xml"],
//categories
['pattern' => 'en/<categorySlug>', 'route' =>
'/blog/post/category', 'defaults' => ['lang' => 'en-US']],
['pattern' => 'es/<categorySlug>', 'route' =>
'/blog/post/category', 'defaults' => ['lang' => 'es']],
//articles
['pattern' => 'en/<categorySlug>/<postSlug>', 'route' =>
'/blog/post/view', 'defaults' => ['lang' => 'en-US']],
['pattern' => 'es/<categorySlug>/<postSlug>', 'route' =>
'/blog/post/view', 'defaults' => ['lang' => 'es']],
]
]
As you can see, there is no need of routes in and routes out, it
automatically build in and out based on the rules, the 'defaults' key on
each rule defines the variables, and the tags (<varName>) in the rules
pattern are mapped as variables too, so calling:
http://myweb.com/contact will call controller site, function contact and
pass variable lang with value en-US
and
url(c="site", f="contact", vars={lang:"en-US"}) will build
http://myweb.com/contact
http://myweb.com/contactarme will call controller site, function contact
and pass variable lang with value es
and
url(c="site", f="contact", vars={lang:"es"}) will build
http://myweb.com/contactarme
http://myweb.com/en/curriculum will call controller post (of blog module),
function view and pass variable lang with value en-US and variable postSlug
with value curriculum-2
and
url(c="blog/post", f="view", vars={lang:"en-US", postSlug="curriculum-2"}
will build http://myweb.com/en/curriculum
http://myweb.com/es/curriculum will call controller post (of blog module),
function view and pass variable lang with value es and variable postSlug
with value curriculum
and
url(c="blog/post", f="view", vars={lang:"es", postSlug="curriculum"} will
build http://myweb.com/es/curriculum
http://myweb.com/my-category/my-post will call controller post (of blog
module), function view and pass variable lang with value en-US and variable
categorySlug with value my-category and variable postSlug with value my-post
and
url(c="blog/post", f="view", vars={lang:"es", postSlug="my-post",
categorySlug="my-category"} will build http://myweb.com/my-category/my-post
In that way we can move the code to a new application, and use a complete
different urls without change one single line of code.
Greetings.
