I tried to call a function on the controller and the function I have created a route, but how to create a route that has uri-> segement ?
Example
$route['select-item'] = 'select_item';
Controllers
function select_item() {
$item = $this->uri->segment(3);
$data = array ('get_item' => $this->Model->My_item($item));
$this->load->view('Myview');
}
Views
<?php echo $row->item;?>
I suggest you use codeigniters wildcards on routes, You can go ahead and set your route to:
$route['select-item/(:any)'] = 'select_item/$1';
then on your controller, just do:
function select_item($item) {
$data = array ('get_item' => $this->Model->My_item($item));
$this->load->view('Myview',$data);
}
And the link in your view should work properly.

I have used a code from Internet to call controller action dynamically. Here is the code for that, and is used in web.php. But I dont fully understand what it does.
Route::match(['get', 'post'], '{controller}/{action?}/{params1?}/{params2?}', function ($controller, $action = 'index', $params1 = '',$params2 = '') {
$params = explode('/', $params1);
$params[1] = $params2;
$app = app();
$controller = $app->make("\App\Http\Controllers\\" . ucwords($controller) . 'Controller');
return $controller->callAction($action, $params);
})->middleware('supadminauth');
Can someone explain?
Route::match(['get', 'post'], '{controller}/{action?}/{params1?}/{params2?}', function ($controller, $action = 'index', $params1 = '',$params2 = '') {
The first line looks at the request to see whether it is a get or post request, if it is some other types of request that means it does not match and will not proceed further. Then the url are separated into 4 parts corresponding by their name and passed into variables with the same name i.e. $controller, $action, $param1 and $params2 where the last 3 variables do not need to be present (with ? at the end of the name).
$params = explode('/', $params1);
$params[1] = $params2;
I believe this is a crude way to create an array of parameters as $params where the following would be more appropriate.
$params = [$params1, $params2];
.
$app = app();
$controller = $app->make("\App\Http\Controllers\\" . ucwords($controller) . 'Controller');
Then load the relevant controller.
return $controller->callAction($action, $params);
And run the corresponding action and passing all the parameters with it.
Hope this makes sense.
This is example of use it:
If you have controller like bellow:
class AdminController extends Controller {
public function index(){ //sample 0, sample 1
...
}
public function view($param1){ //sample2 , sample3
...
}
}
There is some sample route for calling them
sample0: yoursite.com/admin
sample1: yoursite.com/admin/index
sample2: yoursite.com/admin/view
sample3: yoursite.com/admin/view/5
Notice in your question ? in {action?} means it can either have value or not. Other things is simple and clear. Do you need more explaination?
I'm sending an URL hashed and when i get it i have to show a view on Laravel, so i have those functions on the controller and also some routes:
This are my routes:
Route::post('/sendLink', 'Payment\PaymentController#getPaymentLink');
Route::get('/payment?hash={link}', 'Payment\PaymentController#show');
And this are the functions i have on my controller:
public function getPaymentLink (Request $request){
$budgetId = $request['url.com/payment/payment?hash'];
$link = Crypt::decryptString($budgetId);
Log::debug($link);
//here to the show view i wanna send the link with the id hashed, thats why i dont call show($link)
$view = $this->show($budgetId);
}
public function show($link) {
$config = [
'base_uri' => config('payment.base_uri'), ];
$client = new Client($config);
$banking_entity = $client->get('url')->getBody()->getContents();
$array = json_decode($banking_entity, true);
return view('payment.payment-data')->with('banking_entity', $array);
}
And this is getting a "Page not found" message error.
What i want to to is that when i the client clicks on the link i send him that has this format "url.com/payment/payment?hash=fjadshkfjahsdkfhasdkjha", trigger the getPaymentLink function so i can get de decrypt from that hash and also show him the view .
there is no need to ?hash={link} in get route
it's query params and it will received with $request
like:
$request->hash
// or
$request->get('hash')
You need to define route like this:
Route::get('/payment/{hash}', 'Payment\PaymentController#show');
You can now simply use it in your Controller method like below:
<?php
public function getPaymentLink (Request $request,$hash){
$budgetId = $hash;
// further code goes here
}
<?php
namespace App\Http\Controllers;
use Illuminate\Support\Facades\DB;
use App\News;
use App\User;
use App\Event;
public function index()
{
$datanews['newss'] = News::orderBy('created_at','desc')->get();
$dataevent['events'] = Event::orderBy('created_at','desc')->get();
$user['users'] = User::all();
return view('user/aktuelles.index',$datanews, $dataevent,$user);
}
this is a part of my controller, i can show news and events in my view but everytime it says it can not find the variable user?
i dont know why because i dont know why it shows me the other variables but not the user variable???
in my view i can see the other variables like this:
#foreach ($newss as $news)
{{$news->newstitel}}
#endforeach
but i want to show user like this:
{{$user[1]->avatar}}
i tried everything so i tried so look my controller like this:
$user = DB::table('users')->get();
or get the variable via compact
and i tried exactly the same so like this
$user['users'] = User::orderBy('created_at','desc')->get();
and a foreach in my view but it can not found the variable user??
i dont know why
this is the error
Undefined variable: users
return view('user.aktuelles.index', compact('datanews', 'dataevent', 'user');
I am not sure how the helper view() handles the 4th parameter you are passing. According to the docs you can pass data like this:
return view('user/aktuelles.index',[
'datanews' => $datanews,
'dataevent' => $dataevent,
'user' => $user,
]);
or
return view('user/aktuelles.index')->with([
'datanews' => $datanews,
'dataevent' => $dataevent,
'user' => $user,
]);
Maybe give this way a try.
Edit:
The view() helper accepts 3 Parameters: $view = null, $data = [], $mergeData = [] so the 4th parameter you are trying to pass is not even working. You have to pass your data as second parameter or with the chained function with(array $data).
You have to return value in view like below method:
Change this line
$user['users'] = User::orderBy('created_at','desc')->get();
To
$user = User::orderBy('created_at','desc')->get();
return view('user/aktuelles.index', ['datanews' => $datanews,'dataevent'=> $dataevent,'users'=>$user]);
Now, You will get result inside your view using 'users'.
You are not passing variables to view correctly use with or compact to pass variables to view.
i prefer compact as it is simple and easier.
Passing data to view using compact:
namespace App\Http\Controllers;
use Illuminate\Support\Facades\DB;
use App\News;
use App\User;
use App\Event;
public function index()
{
$datanews = News::orderBy('created_at','desc')->get();
$dataevent = Event::orderBy('created_at','desc')->get();
$user = User::all();
return view('user.aktuelles.index',compact('datanews', 'dataevent','user'));
}
Passing variables to view using with:
public function index()
{
$datanews = News::orderBy('created_at','desc')->get();
$dataevent = Event::orderBy('created_at','desc')->get();
$user = User::all();
return view('user.aktuelles.index)->with(['datanews' => $datanews,'dataevent'=> $dataevent,'users'=>$user]);
}
You should try this:
use Illuminate\Support\Facades\DB;
use App\News;
use App\User;
use App\Event;
public function index()
{
$data['news'] = News::orderBy('created_at','desc')->get();
$data['events'] = Event::orderBy('created_at','desc')->get();
$data['users'] = User::all();
return view('user/aktuelles.index', $data);
}
Is there any other best way to use session_data in website.
How i set session in my project:
$sess_array = array('id' => $row->user_id,'name'=>$row->user_name,'email'=>$row->email,'condition'=>'','balance'=>$row->balance,'did_alloted'=>$row->did_alloted,'create_date'=>$row->create_date);
$this->session->set_userdata('logged_in', $sess_array);
when it comes to controller:
$data['id'] = $session_data['id'];
$data['name'] = $session_data['name'];
$data['email'] = $session_data['email'];
$data['balance']=$session_data['balance'];
$data['did_alloted']=$session_data['did_alloted'];
$data['create_date']=$session_data['create_date'];
$this->load->view('san-reception', $data);
and in my view. I use <?php echo $name ?> to get session_data.
So is there any method by which i can directly access session_data in view without including as $data.
$this->session->userdata('logged_in'); will be available directly in views and hence you just need to assigned this to a variable and then use that as array like bellow.
$userdata=$this->session->userdata('logged_in');
now variable $userdata contain all array field that you set in controller and hence you can use it as $userdata['id'], $userdata['name'] etc
public function __construct()
{
parent::__construct();
$data['session_data']=$this->session->user_data('logged_in');
}
public function some_function(){
$data['dummy']="";
$this->load->view('someview3',$data)
}
public function some_function1(){
$data['dummy']="";
$this->load->view('someview1',$data)
}
public function some_function2(){
$data['dummy']="";
$this->load->view('someview2',$data)
}
If you assign that into the constructor then it will call by automatically whenever a function calls in the controller.
you can view it in you view page by,
print_r($session_data);
I'm more or less new to Laravel 4. I've never used routes before but normally what I'm used to is url/controller/action and then the backend routing for me. I've read the documentation for routes and controllers a few times as well as read through some tutorials and so, I'm trying to figure out how to get this to work without writing a route for every controller and action.
I tried something like
Route::get('{controller}/{action}', function($controller, $action = 'index'){
return $controller."#".$action;
});
Now then, I know this is wrong since it doesn't work, but what am I missing? On most tutorials and stuff I'm seeing an route for more or less every controller and action like:
Route::get('/controller/action' , 'ControllerName#Action');
Which seems silly and like a waste of time to me.
Is there anyway to achieve what I want?
If you are looking for a more automated routing, this would be the Laravel 4 way:
Route:
Route::controller('users', 'UsersController');
Controller (in this case UsersController.php):
public function getIndex()
{
// routed from GET request to /users
}
public function getProfile()
{
// routed from GET request to /users/profile
}
public function postProfile()
{
// routed from POST request to /users/profile
}
public function getPosts($id)
{
// routed from GET request to: /users/posts/42
}
As The Shift Exchange mentioned, there are some benefits to doing it the verbose way. In addition to the excellent article he linked, you can create a name for each route, for example:
Route::get("users", array(
"as"=>"dashboard",
"uses"=>"UsersController#getIndex"
));
Then when creating urls in your application, use a helper to generate a link to a named route:
$url = URL::route('dashboard');
Links are then future proofed from changes to controllers/actions.
You can also generate links directly to actions which would still work with automatic routing.
$url = URL::action('UsersController#getIndex');
app\
controllers\
Admin\
AdminController.php
IndexController.php
Route::get('/admin/{controller?}/{action?}', function($controller='Index', $action='index'){
$controller = ucfirst($controller);
$action = $action . 'Action';
return App::make("Admin\\{$controller}Controller")->$action();
});
Route::get('/{controller?}/{action?}', function($controller='Index', $action='index'){
$controller = ucfirst($controller);
$action = $action . 'Action';
return App::make("{$controller}Controller")->$action();
});
I come from .Net world and routing is typically done:
/{Controller}/{action}/{id}
Which looks like:
/Products/Show/1 OR /Products/Show/Beverages
In Laravel I accomplish this routing like so:
Route::get('/{controller?}/{action?}/{id?}', function ($controller='Home', $action='index', $id = null) {
$controller = ucfirst($controller);
return APP::make("{$controller}Controller")->$action($id);
});
The controller would look roughly like so:
class ProductsController extends BaseController {
public function Show($id) {
$products = array( 1 => array("Price" => "$600","Item" => "iPhone 6"),
2 => array("Price" => "$700", "Item" => "iPhone 6 Plus") );
if ($id == null) {
echo $products[1]["Item"];
} else {
echo $products[$id]["Item"];
}
}
}
