Retrieve routing parameters passed by url outside controller, symfony2 - php

I am trying to access my slug parameters outside my controller.
I have a Routing YML like this:
adgroup:
pattern: /adgroup/{id}
defaults: { _controller: ExampleBundle:AdGroup:index }
requirements:
id: \d+
..and a URL like this:
http://example.com/adgroup/25
I need a way to access the {id} variable without getting it from my controller, my controller is working perfectly. However, I am trying to build an Object that will rely heavily based on which Slugs are being passed in.
So far scouring the docs and many, many examples has left me no where.
What Ive tried:
I've var_dumped the entire Request::createFromGlobals method, and it's children to see if its stored in there in anyway. It does not appear so.
Also, since I am on a development environment, the debug toolbar in symfony clearly shows Request: id: 25 in the profiler.
So the question is... How do I get my slugs / slug values from outside the controller?
I have way too many controllers to attempt to pass them in from there 1 by 1, and hacking it from exploding the URL is just a bad idea. :-)
I imagine there is some method I am unaware of to access these?

I think this code will help you
$params = $container->get('request')->attributes->get('_route_params');
$id = $params['id'];

Is it possible to construct a Symfony path using only parameters?

I would like to reduce the number of repetitive code and give a canonical URL in my Drupal 8 application. Since the routing system is built on Symfony, I included it in the title.
I am constructing paths under routes in my mymodule.routing.yml file. I want to match a specified number of different strings in the first argument, and a slug which can be any string in the second argument. It looks like this:
entity.my_entity.canonical:
path: '/{type}/{slug}'
defaults:
_controller: '\namespace\PostController::show'
requirements:
_permission: 'perm'
type: different|strings|that|can|match|
Now, when I try to access using for example /match/some-slug then it just says "Page not found".
If I something static to the path, for example path: '/j/{type}/{slug}', then it works as expected when I open /j/match/some-slug in the browser.
My boss doesn't like any unnecessary characters in the URL though, so I would like to achieve this by using two parameters, like shown in the first example.
As Yonel mentioned in the comments you can use debug:router to check all your routes. I don't see anything wrong with your code.
Try running bin/console router:match "/match/blaaa" and if you see some controller that isn't the one you want then you'll need to change the route. It shouldn't be the case though because you're getting a 404.
Here's my exact setup that works
routing.yml:
entity.my_entity.canonical:
path: '/{type}/{slug}'
defaults:
_controller: 'MyBundle:Something:foo'
requirements:
type: different|strings|that|can|match|
Inside MyBundle\SomethingController:
public function fooAction($id)
{
return new Response("bar");
}
Then going to http://localhost/match/fom shows the "bar" response.
I have read the documentation again (RTM), and found out that it is not possible in Drupal 8, while it is possible in Symfony.
Note that the first item of the path must not be dynamic.

CodeIgniter routes with the same name

I have two different controllers which I want to route to the same URL.
For example,
$route['dashboard/(:any)'] = 'admin/crud/$1';
$route['dashboard/(:any)'] = 'admin/dashboard/$1';
But this is causing 404 errors.
I guess there is some issue with the :any wildcard.
Is there an alternative to use?
CodeIgniter doesn't map controllers to URLs, it maps URLs to controllers. See URI Routing.
You are trying to map two same exact URLs to go to different places. This doesn't make sense.
Also, since $route is just an associative array, you are overwriting the value instead of adding an additional route.
$route['dashboard/(:any)'] = 'admin/crud/$1';
$route['dashboard/(:any)'] = 'admin/dashboard/$1'; //Immediately over writes the previous value
So, it looks like you just have a problem with the second route:
$route['dashboard/(:any)'] = 'admin/dashboard/$1';
Since, admin is the folder, double check that the value being passed in by the route actually is a method in your dashboard controller class.
Also, check out this question and accepted answer: routing controllers in sub folders - codeigniter I think it provides an example of what you are attempting to do.

Symfony 2 #Route annotation case-sensitive

I'm trying to create a url with annotations of the route.
The problem is that I can write any URL large, small or different.
#Route("/{staat}/", name="showStaats",requirements={"location" = "berlin|bayern|brandenburg"})
This URL can be accessed both from www.example.com/berlin and under www.example.com/Berlin.
I would, however, that it is attainable only under www.example.com/berlin.
Answering the question "How to make case-insensitive routing requirement":
You can add case-insensitive modifier to requirement regexp like so:
(?i:berlin|bayern|brandenburg)
You have "/{staat}/", but your requirements set "location" = ..., these should match, so maybe that's the cause of your problem.
If you don't want to hardcode the list of states in your route, you could inject a service containter parameter with a list of states. Just see How to use Service Container Parameters in your Routes in the documentation for how to do that.
If you just want to check, whether that state is all lower-cased you could try the following requirement:
staat: "[a-z-]+"
This should match only lowercase characters and dash (e.g. for "sachsen-anhalt"). But I'm not entirely sure if this will work as the router's regex-detection is a bit quirky.
You could also create a custom Router Loader which will create routes programmatically, e.g. by fetching the list of states from a database or file.
edit:
As I wrote in my comment I would add the list of params as a Service Container parameter, e.g. %my_demo.states% containing a list of states. I'm not sure however if this will work with annotations. So here is a quick workaround how to get it working.
In your app/config/config.yml you append the %my_demo.states% parameter:
my_demo:
states: ["berlin", "brandenburg", "sachsen-anhalt", ... ]
In your app/config/routing.yml there should be something like this:
my_demobundle:
resource: "#MyDemoBundle/Controller/"
prefix: /
type: annotation
The type: annotation and #MyDemoBundle is the relevant part. Add the following route before this one, to make sure it takes precedence:
showStaats:
path: /{state}
defaults: { _controller: MyDemoBundle:State:index }
requirements:
state: %my_demo.states%
This will add a route which will apply before your annotations using the list of states as parameters. This is a bit crude, as you are mixing yml/annotation-based routing, but it's imo still better than cramming a list of 16 states in the annotation, not to mention its easier to maintain.

Symfony2 routing: How to request that the route will be taken from only one template

I heve an embedded controller in my base template. It's a search bar.
For the search bar controller, I have a route "myProject/search".
What I would like is that this route will be taken only when the template where I am embedding the controller (base.html.twig) will call it, and not when i manually put in the browser: "myproject/search".
Any idea on how to do that.
I think, since some time you can't do it:
http://symfony.com/doc/current/book/templating.html#embedding-controllers
quote from the docs:
Even though this controller will only be used internally, you'll need
to create a route that points to the controller
(...)
Since Symfony 2.0.20/2.1.5, the Twig render tag now takes an absolute
url instead of a controller logical path. This fixes an important
security issue (CVE-2012-6431) reported on the official blog. If your
application uses an older version of Symfony or still uses the
previous render tag syntax, you should upgrade as soon as possible.
Anyway, I guess, you can try do it yourself by passing some "secret" argument to search action when you call it from your template. Next in the action you check if the argument was passed to it, and if not you throw 404.
Another way to achieve your goal is use .htaccess file.
You can restrict your route to a certain method by _method option in your routing configuration:
your_rote:
pattern: /myProject/search
defaults: { _controller: YourBundle:YourController:YourAction }
requirements:
_method: POST

MVC - No Controller in the URI?

Let's pretend I'm trying to learn CI, and as my test project I am building a group-buying site.
What I'd like is to have a different page for each city, e.g.:
http://www.groupon.com/las-vegas/
http://www.groupon.com/orlando/
I'd also like to have different pages such as:
http://www.groupon.com/learn
http://www.groupon.com/contact-us
If I am building this in CI and following the MVC ideology, how would this work? I'm having difficulty seeing how to accomplish the desired URL's with the concept of:
http://www.domain.com/controller/view/segment_a/segment_b/etc...
What I would do is create a custom 404 controller that acts as a catch-all for non-existent routes.
It would take the URI, possibly validate it, and re-route it to the (e.g.) "city" controller.
If the city controller can't find the city (whatever string was specified), then it needs to issue a proper 404. Otherwise, you're good to display your information for that city.
Also, once you create your custom 404 controller, you can send all 404 errors to it by specifying a route named '404_override'.
That's where URI Routing comes in. But in your case you'll probably will have to be carefull defining your routes as the first and only part of your route is a variable part already.
This really has nothing to do with MVC, and much more to do with good URL.
You're looking for URLs that are both (a) clear from the user's point of view and (b) that give hints to your application as to how it's meant to be handled.
What I'd do in this case is redesign your URLs slightly so that rather than:
http://www.groupon.com/las-vegas/
http://www.groupon.com/orlando/
You would have URLs that looks like this:
http://www.groupon.com/destinations/las-vegas/
http://www.groupon.com/destinations/orlando/
The bit at the beginning--/destinations/--can be used by your URL routing code to decide what controller should be dealing with it. If your routing code is URL-based, you might have an array like this:
$routes = array(
'/destinations/' => 'on_destination_list',
'/destinations/(.+)' => 'on_destination',
'/(.*)' => 'on_page');
// Basic URI routing code based off of REQUEST_URI
foreach ($pattern => $func) {
if (preg_match("`^$pattern$`", $_SERVER['REQUEST_URI'], $placeholders)) {
array_shift($placeholders);
call_user_func($func, $placeholders);
}
}
Keep in mind that I wrote that routing code off the top of my head and it may not be absolutely correct. It should give you the gist of what you need to do.
Doing things this way has the added benefit that if somebody goes to http://www.groupon.com/destinations/, you'll have the opportunity to show a list of destinations.
