I want to send my data from controller to xedit.blade.php, but I get the same error:
Undefined variable: users
in controller:
public function index3()
{
$users=User::all();
return view('xedit')->with('users' => $users);
}
Routes:
Route::get('admin/edit', function () {
return view('xedit');
})->name('edit');
Route::get('edit','Admin\UsersController#index3');
and I want to use $users in blade.Maybe there is a Route problem?
You have to change
Route::get('edit','Admin\UsersController#index3')->name('edit');
Use this code.
Route::get('/admin/edit','AdminController#index3')->name('edit');
It calls the AdminController's index3() and the function returns the view.
public function index3()
{
$users=User::all();
return view('xedit')->with('users' => $users);
}
The below code won't call the index3() in AdminController but returns
the view directly with empty data.
Route::get('admin/edit', function () {
return view('xedit');
})->name('edit');
maybe this route
Route::get('admin/edit', function () {
return view('xedit');
})->name('edit');
This route doesn't contain $users, maybe this is why it's undefined.
The problem is you are using the same view xedit for both of your routes admin/edit & /edit .
So, when you visit admin/edit $users variable in the xedit view file getting no value which means it's undefined. Try to check if $users variable is defined before using that.

im trying to call a function from another route in laravel php.
I have the route "welcome"
Route::get('/', function () {
return view('welcome');
});
where im calling this extends (sidebar)
#extends('layouts.guestnavbar')
i want to see if my table notifications is empty or not so i made this controller
class GuestNavbarController extends Controller
{
public function isempty(){
$notif = Notification::first();
if(is_null($notif)) {
return view('layouts.guestnavbar')->with("checkempty", "empty");
}else {
return view('layouts.guestnavbar')->with("checkempty", "not empty");
}
}
}
and i called the variable {{ $checkempty }} in my route guestnavbar
Route::get('/guestnavbar', [GuestNavbarController::class, 'isempty']);
and it works when im in the route guestnavbar
but doesnt work when im in the route welcome because i call the function in the route guestnavbar and in welcome he doesnt recognize the variable: checkempty
i need this function to be in the guestnavbar because i have to call it on other pages, not just in welcome page
I appreciate any help.
You don't need isempty inside controller, just add method isempty inside Notification model, you can use something like this inside Notification model:
public static function isEmpty(){
return Notification::first() ? true : false;
}
And then where you need to check if notification table is empty just call Notification::isEmpty()
I am using Laravel AdminLTE and I have it all configured, there is just one part I do not understand. I made my route like so:
Route::get('/admin/painlevel', function () {
return view('painlevel');
});
and I have this method in app/Http/Controllers/v1/PainLevelController.php
public function index()
{
return PdTpainlevel::select('pkpainlevel as id', 'painlevel_name as name')->get();
}
How would I call that method and display the data in my painlevel view?
Your current route is merely returning the view('painlevel') directly.
You need to update your route to:
Route::get('/admin/painlevel', 'V1\PainLevelController#index');
In your controller:
public function index()
{
$data = PdTpainlevel::select('pkpainlevel as id', 'painlevel_name as name')->get();
return view('painlevel', compact('data'));
}
You might want to start glancing through the documentations, start with Route, Controller and View
route create like this
Route::get('/administrator', 'administrator\LoginController#index');
and controller create like this
public function index()
{
$data['title']="Admin | DashBoard";
$data['name']="Dilip Singh Shekhawat";
view('administrator/menu_bar',$data);
return view('administrator/dashboard',$data);
}
its working .
I am very obviously a noob to Laravel and hope that someone can help me out.
The about screen is accessed through the route
Route::get('/about', array('as' => 'about', function()
{
return View::make('about')->with('title','About Screen')->with('class','about');
}));
The variables $title and $class are accessible in about.blade.php by {{ $title }} and {{ $class }}. If instead, I have a Controller in between,
Route::get('hello/create', array('as' => 'create', 'uses' =>
'HelloController#create', function()
{
return View::make('hello/create')->with('title','Create')->with('class','hello.create');
}));
How do I access $title and $class in the HelloController.php code (so that I can propagate the values to the coming View)?
P.S. I do know about the /hello/create/{name of variable} which is the answer on nearly all questions similar to this, but don't know how to use it to transmit variables NOT keyed onto the Http Request.
$title and $class are the values you are manually giving to the blade. These aren't the values that you are receiving in GET parameters in your route. So, you would do it the same way as you did in the closure.
Your route:
Route::get('hello/create', array('as' => 'create', 'uses' => 'HelloController#create'));
Controller method:
class HelloController{
public function create(){
return View::make('hello/create')->with('title','Create')->with('class','hello.create');
}
}
UPDATE:
From what I understood, you can also call controller's method inside the route's closure and pass parameters to the controller and call the view with these values inside the controller's method.
Your route file:
use App\Http\Controllers\HelloController;
Route::get('hello/create',function(){
$hello_obj = new HelloController();
return $hello_obj->create('create','hello.create');
});
Controller method:
class HelloController{
public function create($title,$class){
return View::make('hello/create')->with('title',$title)->with('class',$class);
}
}
First you need to clear your flow. You are -at the moment- manually setting the variables to be returnet to the view, so your route should look like this:
Route::get('hello/create', 'HelloController#create');
Then, your controller handles the logic:
public function create(Request $request)
{
return view('hello.create')->with('title','Create')->with('class','hello.create');
}
Now, if you need to send parameters from your frontend to your controller, you have two options:
Define route parameters.
Use query params.
Option 1
For the first option, you'll need to define your required/optional parameters in the route itselft:
Route::get('hello/create/{a_variable}', 'HelloController#create');
Then you access this parameter in any of this ways:
public function create(Request $request)
{
return view('hello.create')->with('a_variable', $request->a_variable);
}
or injecting the variable in the method:
public function create(Request $request, $a_variable)
{
return view('hello.create')->with('a_variable', $a_variable);
}
Option 2
For the use of query params, you should include this options when making the request. If your route looks like this:
Route::get('hello/create', 'HelloController#create');
You could specify query params like this:
GET www.my-domain.com/hello/create?first_parameter=value_1&second_parameter=value_2
So in your controller you access this values like this:
public function create(Request $request)
{
$value_1 = $request->get('first_parameter');
$value_2 = $request->get('second_parameter');
return view('hello.create')
->with('value_1', $value_1)
->with('value_2', $value_2);
}
You are alreading sending data to view using with().
Echo it in your view file using $variablename set in with() Example: <?php echo $title; ?>
how can i use same route for two different controller function methods in laravel
first controller
public function index()
{
$comproducts = Comproduct::paginate(6);
$items = Item::orderBy('name')->get();
return view('computer', compact(['comproducts', 'items']));
}
second controller
public function index()
{
return view('search.index');
}
i want to use these two different controller functions for one route.
This is my route name
Route::get('/computer', [
'uses' => 'ComputerProductsController#index',
'as' => 'computer.list'
]);
laravel needs somehow to identify which exactly method you want. for example you can pass the parameter, which will identify which method to call.
public function index(Request $request)
{
// if param exists, call function from another controller
if($request->has('callAnotherMethod')){
return app('App\Http\Controllers\yourControllerHere')->index();
}
$comproducts = Comproduct::paginate(6);
$items = Item::orderBy('name')->get();
return view('computer', compact(['comproducts', 'items']));
}
You can't. If you want to add search functionality to your first controller's index page, you should determine which page to show inside your controller.
A possible example controller:
public function index(Illuminate\Http\Request $request)
{
// If the URL contains a 'search' parameter
// (eg. /computer?search=intel)
if ($request->has('search')) {
// Do some searching here and
// show the search results page
return view('search.index');
}
$comproducts = Comproduct::paginate(6);
$items = Item::orderBy('name')->get();
return view('computer', compact(['comproducts', 'items']));
}
I keep getting errors on this line of code and I am not sure what the problem is?
Here is the route:
Route::get('/samples', 'TestsController#index');
Here is the controller line that is causing the error:
public function index()
{
return $this->makeView('samples.create');
}
Here is the error: Method [makeView] does not exist.
try with
public function getIndex()
{
return View::make('samples.create');
}
It should be
public function index()
{
return $this->make::View('samples.create');
}
You forgot the :: between make and View.
Im not aware of a 'makrView' method, but this is how a view is traditionally rendered.
$templateVars = array('varOne' => $templateVariableOne, 'varTwo' => $templateVariableTwo);
return View::make('samples.create', $templateVars);
Assuming you're using Laravel 4, you don't need $this to make a View in a controller.
public function index()
{
return View::make('samples.create');
}
Also you got View and make the wrong way round.
