I got this error-->'NotFoundHttpException in RouteCollection.php line 161'..When i try to call my additional controller in laravel 5.2..Already I did php artisan serve to activate localhost:8000..can you please explain the basic layout of routing with controller in laravel?
NotFoundHttpException occurs when no given route is matched to your given request to a certain endpoint/url.
Make sure you are sending the request to the correct url which is correctly defined in your routes.php (web.php for laravel 5.3+) with it's correct verb, (GET, POST, PATCH, etc).
Basic flow goes like this:
In your routes.php, you'd define a route like:
Route::get("/users", "UsersController#show");
then in your Http folder define that given controller with it's name which you referred in above call and anything proceeding # symbol is a callback function which gets called automatically.
So in your http/UsersController.php, you'd have:
public function show(Request $request) {
//Do something with your request.
return "Something"; //could be an array or string or
//whatever since laravel automatically casts it into JSON,
//but it's strongly recommended to use transformers and compact method.
}
For more information try looking at laravel docs, they provide an amazing way to get started tutorial. Laravel Docs

I faced a weird issue in Laravel today, the version am using is Laravel 5.5 and I have defined a route as below in the application.
Route::get('getplaylist/{playlistid}/{page}', 'Mycontroller#getplaylist');
And in my controller am trying to fetch the parameters, weirdly
dd($request->all()); // results in empty array []
whereas the below one works,
dd($request->playlistid);
Any help would be appreciated on what is happening behind the scenes. The issue am facing is am not able to validate the request since an empty '[]' array is resulted.
Route parameters, like playlistid and page in your example, can be used with the $request->route() method.
Example:
$request->route('playlistid')
You can also fetch all route parameters using $request->route()->parameters().
As #erikgaal already mentioned, these are route parameters, not request parameters.
But, as is written in the docs, it is one of the most basic and core parts of Laravel, that these route parameters get injected into the controller method. Therefore, with your route:
class Mycontroller
{
public function getplaylist(Request $request, $playlistid, $page)
{
// Do stuff
}
}
I am creating APIs for an app. Now app developer wants me to create a fixed base url and pass the ROUTE NAME (Which will point to controller function) as POST variable. Example:
http://example.com/Api
and POST variables like:
action=>'ROUTE_NAME'
But in laravel we can define the routes based upon the url parts as:
http://example.com/Api/ROUTE_NAME
I have tried using a single controller and loading the other controllers based upon SWITCH statements. But that doesn't seem to be a standard practice as i need to add switch condition every time I'll create a new API. Also middleware will not work on the loaded controllers dynamically.
Is there a way in laravel to achieve this? I am using laravel 5.4
You could implement a middleware that listens on the /Api route, which gets the ROUTE_NAME from the $request, then you could use the Route() helper function to find the url of that named route, then redirect the request to that route.
Something like:
// Generating ROUTE_NAME url...
$url = route($request->route_name);
// Redirect to that route...
return redirect()->route($url);
Obviously you'll need to add code to handle if it doesn't find a route etc, maybe return a json response back with a proper error code etc.
I am new to Laravel 5 and I am trying to use the new Form Request to validate all forms in my application.
Now I am stuck at a point where I need to DELETE a resource and I created a DeleteResourceRequest for just to use the authorize method.
The problem is that I need to find what id is being requested in the route parameter but I cannot see how to get that in to the authorize method.
I can use the id in the controller method like so:
public function destroy($id, DeletePivotRequest $request)
{
Resource::findOrFail($id);
}
But how to get this to work in the authorize method of the Form Request?
That's very simple, just use the route() method. Assuming your route parameter is called id:
public function authorize(){
$id = $this->route('id');
}
You can accessing a Route parameter Value via Illuminate\Http\Request instance
public function destroy($id, DeletePivotRequest $request)
{
if ($request->route('id'))
{
//
}
Resource::findOrFail($id);
}
Depending on how you defined the parameter in your routes.
For my case below, it would be: 'user' not 'id'
$id = $this->route('user');
Laravel 5.2, from within a controller:
use Route;
...
Route::current()->getParameter('id');
I've found this useful if you want to use the same controller method for more than one route with more than one URL parameter, and perhaps all parameters aren't always present or may appear in a different order...
i.e. getParameter('id')will give you the correct answer, regardless of {id}'s position in the URL.
See Laravel Docs: Accessing the Current Route
After testing the other solutions, seems not to work for laravel 8, but this below works
Route::getCurrentRoute()->id
assuming your route is
Route::post('something/{id}', ...)
I came here looking for an answer and kind of found it in the comments, so wanted to clarify for others using a resource route trying to use this in a form request
as mentioned by lukas in his comment:
Given a resource controller Route::resource('post', ...) the parameter you can use will be named post
This was usefull to me but not quite complete. It appears that the parameter will be the singular version of the last part of the resource stub.
In my case, the route was defined as $router->resource('inventory/manufacturers', 'API\Inventory\ManufacturersController');
And the parameter available was manufacturer (the singular version of the last part of the stub inventory/manufacturers)
you will get parameter id if you call
request()->route('id')
OR
$this->route('id')
if you're using resource routing, you need to call with the resource name
// eg: resource
Route::resource('users', App\Http\Controllers\UserController::class);
$this->route('user')
in Terminal write
php artisan route:list
to see what is your param name
Then use
$this->route('sphere') to get param
I'm just new to Laravel but I immediately fell in love with it. As a not so super experienced php developer I do find the official documentation, although very expansive, somewhat complicated to use and find everything I need.
My question is about the Routing component. As the documentation states you can assign a route to a controller with the Route::controller method. So if I want a Blog controller for all /blog/ routes I assign it like this:
Route::controller('blog', 'BlogController');
So then if I'd like to acces all my blog posts I acces the the getIndex method by www.foo.com/blog or www.foo.com/blog/index
But let's say I'd like to be able to display categories via a getCategory method. My url would look like www.foo.com/blog/category and if, for example, I want to get the news category from the DB by slug, I'd like to use: www.foo.com/blog/category/news as the URI.
My question now is, how do I pass the slug to the url and access it in the getCategory method? Do I need specify it via Route::get('blog/category/{slug}', 'BlogController#getCategory') or is there a way to use Route::controller('blog', 'BlogController') and to send and acces parameters from the URL in the getCategory method?
I already tried to find it via google and in the official documentation, but I couldn't find a crystal clear answer to this problem...
You can simply add parameters to your getCategory method:
public function getCategory($category) {
die($category);
}
If you initialize it to null in the parameter list, it becomes optional. Alternatively, you can always pull parameters from the Input object but they would need to be passed in querystring format:
$category = Input::get('category');
With that said, I'd caution against using the Controller route. It's handy and mimics traditional MVC frameworks, but I believe it's planned to be deprecated -- and honestly, you miss out on some pretty flexible features.
using Route::controller('blog', 'BlogController'); allows you to define a single route to handle every action in a controller using REST naming conventions.then you have to add methods to your controller, prefixed with the HTTP verb they respond to. That means if you have a method called getIndex() it will be executed when there is a GET request to the url "yoursite.com/blog".
To handle POST requests to the same url add a method prefixed with post(ex: postComment()) and so on for other http verbs PUT, PATCH and DELETE.
I think you want something more customized, so you can use a resource controller:
Route::resource('blog', 'BlogController');
This will generate some RESTful routes around the blog resource, run php artisan routes in your project folder to see the generated routes, it should be something like this:
Verb Path Action Route Name
GET /blog index blog.index
GET /blog/create create blog.create
POST /blog store blog.store
GET /blog/{blog} show blog.show
GET /blog/{blog}/edit edit blog.edit
PUT/PATCH /blog/{blog} update blog.update
DELETE /blog/{blog} destroy blog.destroy
in the action column are the functions that you should have in the controller.
If you want to define more routes you can simply do it with Route::get or Route::post in the routes.php file
I hope this will make it more clear for you, enjoy routing with Laravel!!!
I've had this working but now a route is no longer found and I can't see why.
In a javascript function I am making an ajax post to the function with this url:
url: '/customers/storeajax',
In my routes.php file I have the following routes:
Route::post('customers/storeajax', array('as'=>'storeajax', 'uses' => 'CustomersController#storeAjax'));
Route::post('customers/updateajax/{id}', array('as'=>'updateajax','uses' => 'CustomersController#updateAjax'));
Route::resource('customers', 'CustomersController');
Now when I try to POST to the storeajax route I get a ModelNotFoundException which to me means the route could not be found so it defaults to the default customers controller show method - in the error log I can see the following entry:
#1 [internal function]: CustomersController->show('storeajax')
confirming its treating the storeajax as a parameter.
I've placed my additional routes above the default resource route
I've had this working before I can't see where I've gone wrong.
In addition these routes are placed in a group:
Route::group(array('before' => 'sentryAuth'), function () {}
which simply ensures user is logged on. To test though I've removed outside the group and at the top of the file but still they don't work.
The url in my browser is coming up correctly as: http://greenfees.loc/customers/storeajax (which I can see in firebug console
I'm using POST as the ajax method - just to confirm
Can anyone see why this route doesn't work and what I've missed?
Update:
Here's the method inside the controller:
public function storeAjax()
{
$input = Input::all();
$validation = Validator::make($input, Customer::$rules);
if ($validation->passes())
{
$customer = $this->customer->create($input);
return $customer;
}
return Redirect::route('customers.create')->withInput()
->withErrors(validation)
->with('message', 'There were validation errors.');
}
I'm 99% certain though that my route is not reaching this method (i've tested with a vardump inside the method) and the issue relates to my route customer/storeajax cannot be found.
What I think is happening is as customer/storeajax is not found in the list of routes starting with customer it is then defaulting to the resource route that appears on the list and thinks this is a restful request and translating it as customer route which defualts to the show method and using the storeajax as the parameter which then throws the error modelnotfoundexception because it cant find a customer with an id of 'storeajax'
This is evidence by the log detailing a call to the show method as above.
So for some reason my route for '/customers/storeajax' cannot be found even though it appears to be valid and appears before the customers resource. The modelnotfoundexception is a red herring as the cause is because of the routes defaulting to the resource constroller of customers when it cant find a route.
A route not being found raises a NotFoundHttpException.
If you are getting a ModelNotFoundException is because your route is firing and your logic is trying to find a Model, wich it can't somehow, and it is raising a not found error.
Are you using FindOrFail()? This is an example of method that raises this exception. BelongsToMany() is another one that might raise it.
I solved this by renaming the method in the controller to 'newAjax' and also updating the route to:
Route::post('customers/new', array('as'=>'newajax','uses' => 'CustomersController#newAjax'));
the terms store I assume is used by the system (restful?) and creating unexpected behaviour. I tested it in a number of other functions in my controller - adding the term store as a prefix to the method then updating the route and each time it failed.
Something learned.
