How can I get current controller & action in Lumen
Let say I have a User resource in the routing.
Then if I access the user/show/id, can I get the current controller name & action name in the Controller?
class Controller extends BaseController
{
public function __construct()
{
$controllerName = ???;
$actionName = ???
}
}
Here is one simple trick to get action and controller name
class Controller extends BaseController
{
public function __construct()
{
$this->_request = app('Illuminate\Http\Request');
list($controllerName ,$actionName)=explode('#',$this->_request->route()[1]['uses']);
print_r($controllerName);
print_r($actionName);
}
}
With this you will have Action and Controller name (just name with no route):
class Controller extends BaseController
{
public function __construct()
{
list($controllerName, $actionName) = explode('#', substr(strrchr($request->route()[1]['uses'], '\\'), 1));
}
}
I have used and checked in Laravel / Lumen 8 version to get controller and action name in controller:
public function getControllerActionName(){
$this->_request = app('Illuminate\Http\Request');
list($controllerName ,$actionName) = explode('#',$this->_request->route()[1]['uses']);
$controllerName = strtolower(str_replace("App\Http\Controllers\\",'',$controllerName));
$actionName = strtolower($actionName);
return array('controller' => $controllerName, 'action' => $actionName);
}
It worked for me. I hope, this will also help you. Thanks for asking this question.

how can i manage url in address bar after posting a form or after loading a page after submission.
Is it possible to manage with routing ?
<?php
public function index(){
$this->load->view('login');
}
public function login_process(){
....... code......
if($login==true){
$this->load->view('dashboard'); // Url is not changing but view is loaded
}else{
$this->load->view('login');
}
}
?>
Hope this will help you :
Use redirect() method from url helper , make sure you load it in controller or in autoload.php
public function login_process()
{
....... code......
if($login === TRUE)
{
redirect('controller_name/dashboard','refresh');
/*$this->load->view('dashboard'); */
}
else
{
redirect('controller_name/index','refresh');
/*$this->load->view('login');*/
}
}

You should create another method called dashboard and you should redirect to it like following
class Example_Controller extends CI_Controller {
public function index(){
$this->load->view('login');
}
public function dashboard(){
$this->load->view('dashboard');
}
public function login_process(){
// Your Code
redirect('Example_Controller/' . (($login==true) ? 'dashboard' : 'index'));
}
}
replace Example_Controller with your controller name.
and add following lines in routes.php
$route['login'] = 'Example_Controller/index';
$route['dashboard'] = 'Example_Controller/dashboard';
Been at this for ages, can't find a solution. I've searched and none of the posts help, possibly me not getting it as I'm new to Laravel (5.4)
I want to be able to be able to access $site_settings from one controller to another. Also $site_settings need to be accessible on all controllers and views. I also need to get variable from URL (hence Request in __construct( Request $request ) ) but it doesn't work either.
Would really appreciate any assistance.
Thanks.
See code below:
//BaseController
class BaseController extends Controller {
public function __construct( Request $request )
{
$slug = $request->slug;
$site_settings = \DB::table('sites_settings')->where('slug', $slug)->first();
View::share( 'site_settings', ['slug' => $slug, 'color' => $color] );
}
}
class SettingsController extends BaseController
{
// SettingsController
public function index( )
{
//how do I access $site_settings here and pass it on to the view?
// return view('settings.index');
}
}
---- UPDATE with Session ----
//BaseController
class BaseController extends Controller {
public function __construct()
{
$slug = Route::input('slug');
if(Session::get('slug') == $slug)
{
dd(Session::get('slug'));
}
else
{
$site_settings = \DB::table('sites_settings')->where('slug', $slug)->first();
Session::put('slug', $site_settings->slug);
}
}
}
I have to build an api.
It has one route. The client is sending a POST request with an XML.
Based on that xml, I have to decide witch controller#action to be called.
And I have a lot of controllers.
Unfortunately I can't modify the client side.
Do you have any suggestion how can i do that in a Laravel way?
For example
POST["body"] =
"...
<controller>content</controller>
<action>index</action>
..."
I want to call a ContentController::index()
Thx!
Thx for the reflection stuff. It is a big magic, worth the effort to look into it deeper.
I have no problem to parse the xml. So here is a simplier example
URL: /api/request/content/show
Routes.php
Route::get('api/request/{controller}/{action}', 'ApiController#request');
ApiController.php
class ApiController extends Controller
{
public function request($controller, $action)
{
//some error check
$controller = 'App\Http\Controllers\\' . ucfirst($controller) . 'Controller';
$params = "Put some params here";
$reflectionMethod = new \ReflectionMethod($controller, $action);
$reflectionMethod->invoke(new $controller, $params);
}
}
ContentController.php
class ContentController extends Controller
{
public function show($params)
{
dd($params);
}
}
And it is working!
Thx a lot!
A better option is to use App::call(); invoking controller with ReflectionMethod might not let you use response() inside your new forwarded controller and other laravel goodies.
Here is my try on this: /api/request/content/show
Routes web.php or api.php
use App\Http\Controllers\ApiController;
Route::get('api/request/{controller}/{action}', [ApiController::class, 'request']);
ApiController.php
class ApiController extends Controller
{
public function request($controller, $action)
{
//some error check
return App::call('App\Http\Controllers\\'.ucfirst($controller).'Controller#'.$action);
}
}
ContentController.php
use Illuminate\Http\Request;
class ContentController extends Controller
{
public function show(Request $request)
{
dd($request);
}
}
This will allow you more freedom.
I have a controller in Laravel 4, with a custom variable declared within it.
class SampleController extends BaseController{
public $customVariable;
}
Two questions: Is there any way I can call within a route filter:
The controller object where the filter is running at.
The custom variable from that specific controller ($customVariable).
Thanks in advance!
as per this post:
http://forums.laravel.io/viewtopic.php?pid=47380#p47380
You can only pass parameters to filters as strings.
//routes.php
Route::get('/', ['before' => 'auth.level:1', function()
{
return View::make('hello');
}]);
and
//filters.php
Route::filter('auth.level', function($level)
{
//$level is 1
});
In controllers, it would look more like this
public function __construct(){
$this->filter('before', 'someFilter:param1,param2');
}
EDIT:
Should this not suffice to your needs, you can allways define the filter inside the controller's constructor. If you need access to the current controller ($this) and it's custom fields and you have many different classes you want to have that in, you can put the filter in BaseController's constructor and extend it in all classes you need.
class SomeFancyController extends BaseController {
protected $customVariable
/**
* Instantiate a new SomeFancyController instance.
*/
public function __construct()
{
$ctrl = $this;
$this->beforeFilter(function() use ($ctrl)
{
//
// do something with $ctrl
// do something with $ctrl->customVariable;
});
}
}
EDIT 2 :
As per your new question I realised the above example had a small error - as I forgot the closure has local scope. So it's correct now I guess.
If you declare it as static in your controller, you can call it statically from outside the controller
Controller:
class SampleController extends BaseController
{
public static $customVariable = 'test';
}
Outside your controller
echo SampleController::$customVariable
use:
public function __construct()
{
$this->beforeFilter('auth', ['controller' => $this]);
}
I'm not CI programmer, just trying to learn it. Maybe this is wrong approach, please advice.
my controller(not in sub directory) :
class Users extends CI_Controller {
function __construct() {
parent::__construct();
}
public function index($msg = NULL) {
$this->load->helper(array('form'));
$data['msg'] = $msg;
$this->load->view('user/login' , $data);
}
public function process_logout() {
$this->session->sess_destroy();
redirect(base_url());
}
}
And a route for login :
$route['user/login'] = 'users/index';
Problem is when I wanna logout, it shows me 404 because I do not have it in my route :
$route['user/process_logout'] = 'users/process_logout';
and in my view I put logout
When I add that, it works, and that is stuppid to add a route for everything. What I'm I doing wrong, please advice.
Thank you
Don't know why you are trying to implement login feature in index() function. However since you said you are learning CI I'm telling something about _remap() function.
Before that. You can try the following routing:
$route['user/:any'] = 'users/$1';
$route['user/login'] = 'users/index';
If you want to take value immediately after controller segment you need to use _remap() function and this function may be solve your routing problem, i mean you don't need to set routing. Lets implement your code controller 'users' using _remap() function.
class Users extends CI_Controller {
private $sections = array('login', 'logout');
function __construct() {
parent::__construct();
}
public function _remap($method)
{
$section = $this->uri->segment(2);
if(in_array($section, $this->sections))
call_user_func_array(array($this, '_'.$section), array());
else show_404(); // Showing 404 error
}
private function _login()
{
$msg = $this->uri->segment(3);
$this->load->helper(array('form'));
$data['msg'] = $msg;
$this->load->view('user/login' , $data);
}
public function _logout() {
$this->session->sess_destroy();
redirect(base_url());
}
}
