Default route arguments in Slim
A friend of mine recently asked how to do default route arguments and route specific configuration in Slim, so I thought I’d write up how to do it.
Consider a simple Hello route:
|
1 2 3 4 |
$app->get("/hello[/{name}]", function ($request, $response, $args) { $name = $request->getAttribute('name'); return $response->write("Hello $name"); }) |
This will display “Hello ” for the URL /hello and “Hello Rob” for the URL /hello/Rob.
If we wanted a default of “World”, we can set an argument on the Route object that is returned from get() (and all the other routing methods):
|
1 2 3 4 |
$app->get("/hello[/{name}]", function ($request, $response, $args) { $name = $request->getAttribute('name'); return $response->write("Hello $name"); })->setArgument('name', 'World'); |
This works exactly as you would expect.
The route arguments don’t have to be placeholder and you can set multiple route arguments. For example:
|
1 2 3 4 5 6 7 8 |
$app->get("/hello[/{name}]", function ($request, $response, $args) { $name = $request->getAttribute('name'); $foo = $request->getAttribute('foo'); return $response->write("Hello $name, foo = $foo"); })->setArguments([ 'name' => 'World, 'foo' => 'bar', ]); |
Now, we have a foo attribute in our request, which is a per-route configuration option that you can do with as you wish – e.g. setting acl rules like this:
|
1 |
$app->get("/users", App\HelloAction::class)->setArgument("role", "userAdministrator"); |
Hi ROB @akrabat !!!
my question is…
in my old route:
$app->get('/', function ($request, $response, $args) {
// Render index view
$res = $this->renderer->render($response, 'site/index.php', $args);
});
and
$app->get('/profile/{user_name}', function ($request, $response, $args) {
$res = $this->renderer->render($response, 'site/username_template.php', $args);
});
this was working without problem….
but in the new requeriment… they want….
$app->get('/{user_name}', function ($request, $response, $args) {
$res = $this->renderer->render($response, 'site/username_template.php', $args);
});
without prefix . . .
but the also want . . .
$app->get('/{user_name}/orders', function ($request, $response, $args) {
$res = $this->renderer->render($response, 'site/orders_template.php', $args);
});
$app->get('/{user_name}/products', function ($request, $response, $args) {
$res = $this->renderer->render($response, 'site/products_template.php', $args);
});
and
$app->get('/cart', function ($request, $response, $args) {
$res = $this->renderer->render($response, 'site/cart_template.php', $args);
});
$app->get('/cart/detail', function ($request, $response, $args) {
$res = $this->renderer->render($response, 'site/cart_details_template.php', $args);
});
**How can we create these rules and considering that the {user_name} is dynamic, is in the database the user UNIQUE user, how to do so that you can interpret that and the routes ( /cart and /cart/detail )at the same time**
