I'm reading the Laravel documentation and it is saying that it is possible to add a pattern based filter to a route
Route::filter('admin', function()
{
//
});
Route::when('admin/*', 'admin');
I want to know how to specify if the filter is executed before or after the request?
Pattern filters are always called before and cannot be called after a routes execution.
You can see it being called in the source (4.1.24) on GitHub.
A solution to this is to have all your admin routes inside a route group and apply the filter to the entire group.

I am developing an application in the Laravel 5.2 which must have a friendly URL-s. This is not problem with the regular way, where the {slug} wildcard is handled by a controller but I want to make it in a different way.
For now I have only two controllers:
ProductsController#show to show details product
CategoriesController#show to show selected category with listing products which are assigned to it
And routes:
Route::get('product/{product}', 'ProductsCategory#show')->name('product.show');
Route::get('category/{category}', 'CategoriesController#show')->name('category.show');
So when I want to echo a just use route('product.show', compact('product'))
Nothing special until I want to handle different URL-s which are fetched from a database. I thought it will be possible to make an another routes which are assigned to existing and when I use a route(...) helper it will be handled automatically. But it is not. So for example I have a new URL:
domain.com/new-url-for-product.html
so by route it should be assigned to the regular 'product.show' route with some ID, which is handled by route model binder for {product} wildcard. The same for route(..) helper it should print friendly URL-s.
I don't know if my strategy is good. How do you handle with the similar problems?
of course route will handle this automatically. have a look into this. I am just giving you example, you have to set this code as per your need.
route('product.show', 'product'=>'new-url-for-product.html');
will generate this
domain.com/new-url-for-product.html
route('product.show', 'product'=>'new-url2-for-product.html');
will generate this URL
domain.com/new-url2-for-product.html
and so on, and then you have to handle all this in your controller method.
eg: your controller method for this route is ProductsCategory#show which is
public function show($product){
if($product == 'new-url-for-product.html'){
//perform this
}
if($product == 'new-url2-for-product.html'){
//perform this
}
}
this just an example, you have to map this according to your need
Edited Here is the example I tested it
Route::get('/product/{product}.html', ['as'=>'product.show', 'uses'=>'ProductsCategory#show']);
I'm using Laravel 5.1 and am building a service that can be seen as JSON or HTML. This approach is already done by sites like reddit.
Example
Normal view: http://www.reddit.com/r/soccer
JSON view: http://www.reddit.com/r/soccer.json
As you can see, they simply add .json to an URL and the user is able to see the exact same content either as HTML or as JSON.
I now wanted to reproduce the same in Laravel, however I'm having multiple issues.
Approach 1 - Optional parameter
The first thing I tried was adding optional parameter to all my routes
Route::get('/{type?}', 'HomeController#index');
Route::get('pages/{type?}', 'PageController#index');
However, the problem I was facing here, is that all routes were caught by the HomeController, meaning /pages/?type=json as well as /pages?type=json were redirected to the HomeController.
Approach 2 - Route Grouping with Namespaces
Next I tried to add route groupings with namespaces, to seperate backend and frontend
Route::get('pages', 'PageController#index');
Route::group(['prefix' => 'json', 'namespace' => 'Backend'], function(){
Route::get('pages', 'PageController#index');
});
However, this doesn't work either. It does work, when using api as prefix, but what I want, is that I can add .json to every URL and get the results as json. How can I achieve that in Laravel?
You can apply regular expressions on your parameters to avoud such catch-all situation as you have for HomeController#index:
Route::get('/pages{type?}', 'PageController#index'->where('type', '\.json'));
This way it type will only match, if it is equal to .json.
Then, to access it in your controller:
class PageController {
public function index($type = null) {
dd($type);
}
}
and go to /pages.json
I'm trying to set up a routing prefix in cakephp 3 so any URLs starting with /json/ get the prefix key set and I can change the layout accordingly in the app controller. Other than that, they should use the usual controller and action. I have added the following to routes.php
$routes->prefix('json', function($routes) {
$routes->connect(
'/:controller/:action/*',
[],
['routeClass' => 'InflectedRoute']
);
});
I want to direct all requests with json as first url segment to controller specified in second url segment. e.g. /json/users/add_account_type/ goes to users controller. However when accessing this URL I get the message:
Error: Create the class UsersController below in file:
src/Controller/Json/UsersController.php
whereas I want it to be using
src/Controller/UsersController.php
I think this should be possible but I can't quite see what I'm doing wrong when consulting the book. Have partly based my code on: CakePHP3.x controller name in url when using prefix routing
Thanks a lot in advance
That's simply how prefix routing now works in 3.x, as explained in the docs, prefixes are being mapped to subnamespaces, and thus to separate controllers in subfolders.
http://book.cakephp.org/3.0/en/development/routing.html#prefix-routing
If you'd wanted to change that behavior (I don't really see why), one way would be to implement a custom ControllerFactory dispatcher filter.
http://book.cakephp.org/3.0/en/development/dispatch-filters.html
On a side note, the RequestHandler component supports layout/template switching out of the box, so maybe you should give that a try.
http://book.cakephp.org/3.0/en/controllers/components/request-handling.html
http://book.cakephp.org/3.0/en/views/json-and-xml-views.html
Prefix routing is a way of namespacing parts of your routes to a dedicated controller. It seem that what you want is a scope and not a prefix, for what you describe:
Router::scope('/json', function($routes) {
$routes->fallbacks('InfledtedRoute')
});
So we have a load of content within the database, let's call these Articles. The paths for the Articles start from the application root and can contain slashes. So we want to search the DB to see if we match an Article, and if not skip the route and give other routes the opportunity to respond.
In Sinatra (which I believe has inspired the routing within Laravel) you have the option to pass to the next route. It might be this that's leading me astray.
Route::get( '{uri}', function( URI $uri ) {
// check database, if we find a record we'll need to pass it to the appropriate controller
// we'll have a class that handles this responsiblity
// pass if we don't find anything
} )->where('uri', '.*');
Route::get( 'other/page', 'OtherController#sayHello' );
The issue Allow skip the route based on conditions #1899 talks about this, although I can't see how filters cater for this, they will simply intercept and give you an opportunity to stop route execution (throw exception, redirect to route specifically etc.), you can't return FALSE; without error. There is an example chaining a condition method to a route, although this method doesn't seem to exist (in 4.2).
Any ideas?
In addition to this, we're also are thinking about containing this logic within a package so it can be shared across applications, and wonder if you can influence the order of execution of routes provided by package?
You can have a group of routes, which you contain within all the routes that match it. If it fails that group then it skips to the next section.
Route::group(array('before' => 'auth'), function()
{
Route::get('/', function()
{
// Has Auth Filter
});
Route::get('user/profile', function()
{
// Has Auth Filter
});
});

I'm wondering if it is possible to use optional parameters in a group prefix.
Using it with {parameter?} like in any other route doesn't work:
Route::group(array('prefix' => 'foo/{foo_id?}'), function() {
Route::any('bar', 'ApiFooController#bar');
});
I would like to catch both foo/bar and foo/2/bar.
As much as I can see, it only works without the questionmark but then foo/bar(without the parameter) throws an error.
I would like to avoid defining two seperate groups which would be a workaround. Maybe Important to note: bar is a custom function in addition to a resource so I'm not trying to define a resource (like foo.bar).
I think you might have to define the route twice, but you don't have to create another group.
Does this work for you?
Route::group(array('prefix'=>'foo'),function() {
Route::any('bar', 'ApiFooController#bar');
Route::any('{foo_id}/bar', 'ApiFooController#bar');
});
