How to pass database value from controller to dashboard in Laravel 9 - php

I have a method in my controller, PostsController:
public function index()
{
$post = Posts::where('id', '1')->get(['post']);
return $post;
}
web.php
Route::get('test', [PostsController::class, 'index']);
into test.blade.php in my views folder, and show it with
{{ $post }}
This works perfectly. However, when I try to do the exact same thing to the dashboard.blade.php, I get
Undefined variable $post
When trying to get this data on dashboard, I use this in app.php instead.
Route::get('dashboard', [PostsController::class, 'index']);
I was expecting to get the same data on the dashboard as in test.blade.php, but it cannot find the variable anymore as soon as I change the view in the route. What am I doing wrong?

try this
return view('test', [
'post' => Posts::where('id', '1')->get()
]);
and if your test.blade is not directly inside the views folder you need to specify the folder like that: view('folderName.test', ...)
and for more information, you can check the documentation https://laravel.com/docs/9.x/controllers

How do I give route name to a closure route in Lumen?

Hi I have the following Lumen Route
$router->get('/end', function (\Illuminate\Http\Request $request) use ($router) {
$controller = $router->app->make('App\Http\Controllers\Legacy\EndLegacyController');
return $controller->index($request);
});
I am trying to give it a route name so that I can use redirect to redirect to this route like redirect()->route('name_of_route')
so far I have tried
})->namedRoute['end'] = '/end'; // No Effect
})->name('end') //Undefined function
but it didn't work
here's a list of present routes
Edit
Because of my certain requirement, I can't use ['as' => 'end', 'uses'=> 'ControllerName#Action']
you can use the following syntax: $router->get('/end', ['as'=>'name_here', function()]);

Redirect to a controller action, action not defined

I'm using Laravel 5.5.
My objective is to redirect to another method on the same controller to display a view with data.
class SeancesController extends Controller {
...
public function getRecommandations(Request $request) {
...
$data = [
'recommandationAutresActiviteMemeDateHeure' => $recommandationAutresActiviteMemeDateHeure,
'recommandationsMemeActiviteMemeHeure' => $recommandationsMemeActiviteMemeHeure,
'recommandationsMemeActiviteMemeDate' => $recommandationsMemeActiviteMemeDate
];
return redirect()->action('SeancesController#showRecommandations', $data);
}
public function showRecommandations(Request $request) {
return view('listeRecommandations', $request->data);
}
}
It is the right way to do this? Because I get this error :
InvalidArgumentException: Action App\Http\Controllers\SeancesController#showRecommandations not defined. in file /home/nicolas/public_html/M1_CSI/vendor/laravel/framework/src/Illuminate/Routing/UrlGenerator.php on line 338
I need to use action because I use an ajax call to access at getRecommandations().
I used this doc : http://laraveldaily.com/all-about-redirects-in-laravel-5/.
I didn't add a route that points to showRecommendations on my routing file. It's a problem?
Thank's for help!
I didn't add a route that points to showRecommendations on my routing file. It's a problem?
yes , it is a problem. because the redirector checks the routes that are assigned to the action and redirects the user to the route.

Call to a member function name() on null in laravel 5.4

When pressing my send button it's giving error like this-
Here is my routes web.php bellow-
Route::group(['prefix'=>'ajax', 'as'=>'ajax::'], function() {
Route::resource('message/send', 'MessageController#ajaxSendMessage')->name('message.new');
Route::delete('message/delete/{id}', 'MessageController#ajaxDeleteMessage')->name('message.delete');
});
Here is my controller MessageController.php bellow:
public function ajaxSendMessage(Request $request)
{
if ($request->ajax()) {
$rules = [
'message-data'=>'required',
'_id'=>'required'
];
$this->validate($request, $rules);
$body = $request->input('message-data');
$userId = $request->input('_id');
if ($message = Talk::sendMessageByUserId($userId, $body)) {
$html = view('ajax.newMessageHtml', compact('message'))->render();
return response()->json(['status'=>'success', 'html'=>$html], 200);
}
}
}
Resource routes should be named differently:
Route::prefix('ajax')->group(function () {
Route::resource('messages', 'MessageController', ['names' => [
'create' => 'message.new',
'destroy' => 'message.destroy',
]]);
});
Resource routes also point to a controller, instead of a specific method. In MessageController, you should add create and destroy methods.
More info at https://laravel.com/docs/5.4/controllers#restful-naming-resource-routes
You can't name a resource. Laravel by default name it, if you want to name all routes you must specify each one explicitly. It should be like this:
Route::group(['prefix'=>'ajax', 'as'=>'ajax::'], function() {
Route::get('message/send', 'MessageController#ajaxSendMessage')->name('message.new');
Route::delete('message/delete/{id}', 'MessageController#ajaxDeleteMessage')->name('message.delete');
});
Update
Another mistake of yours was trying to resource a single method. A Route::resource() is used to map all basic CRUD routes in Laravel by default. Therefore, you have to pass the base route and the class i.e:
<?php
Route::resource('message', 'MessageController');
Look at web.php line 28.
Whatever object you think has a name() method, hasn't been set, therefore you try and call a method on null.
Look before that line and see where it is (supposed to be) defined, and make sure it is set to what it should be!

Laravel 4: Unable to generate a URL, as such route does not exist

Here is my routes.php:
Route::group(['prefix' => 'mine'], function () {
Route::get('/first', ['as' => 'mine.first', 'uses' => 'MyApp\Controllers\MyController#first']);
});
Here is my HTML/Twig file:
{{ form_open({'action': 'mine.first'}) }}
{{ form_submit('Start') }}
{{ form_close }}
And here is my controller:
class MyController extends BaseController {
public function first()
{
\View::make('stuff.mine.first'); //in folder app/views/stuff/mine
}
}
The error is "An exception has been thrown during the rendering of a template ("Unable to generate a URL for the named route "MyController#first" as such route does not exist.") in "stuff.show" at line 130."
All the answers on this topic that I've seen are to name the route, but I've already done that.
Also, when I go to the URL manually (localhost/mine/first), the screen is blank even though there is HTML in that file.
Any idea what's going on? Thanks.
mine.first is a route name, not an action.
Use:
{{ form_open({'route': 'mine.first'}) }}
As for the view, controller action need to return a Response (the View generates one), so you just need add the proper keyword:
public function first()
{
return \View::make('stuff.mine.first');
}

Unable to generate a URL

I am currently trying to create a link on the index page that'll allow users to create an item. My routes.php looks like
Route::controller('items', 'ItemController');
and my ItemController looks like
class ItemController extends BaseController
{
// create variable
protected $item;
// create constructor
public function __construct(Item $item)
{
$this->item = $item;
}
public function getIndex()
{
// return all the items
$items = $this->item->all();
return View::make('items.index', compact('items'));
}
public function getCreate()
{
return View::make('items.create');
}
public function postStore()
{
$input = Input::all();
// checks the input with the validator rules from the Item model
$v = Validator::make($input, Item::$rules);
if ($v->passes())
{
$this->items->create($input);
return Redirect::route('items.index');
}
return Redirect::route('items.create');
}
}
I have tried changing the getIndex() to just index() but then I get a controller method not found. So, that is why I am using getIndex().
I think I have set up my create controllers correctly but when I go to the items/create url I get a
Unable to generate a URL for the named route "items.store" as such route does not exist.
error. I have tried using just store() and getStore() instead of postStore() but I keep getting the same error.
Anybody know what the problem might be? I don't understand why the URL isn't being generated.
You are using Route::controller() which does generate route names as far as I know.
i.e. you are referring to "items.store" - that is a route name.
You should either;
Define all routes specifically (probably best - see this blog here)
Use Route::resource('items', 'ItemController'); see docs here
If you use Route::resource - then you'll need to change your controller names
The error tells you, that the route name is not defined:
Unable to generate a URL for the named route "items.store" as such route does not exist.
Have a look in the Laravel 4 Docs in the Named Routes section. There are several examples that'll make you clear how to use these kind of routes.
Also have a look at the RESTful Controllers section.
Here's an example for your question:
Route::get('items', array(
'as' => 'items.store',
'uses' => 'ItemController#getIndex',
));
As The Shift Exchange said, Route::controller() doesn't generate names, but you can do it using a third parameter:
Route::controller( 'items',
'ItemController',
[
'getIndex' => 'items.index',
'getCreate' => 'items.create',
'postStore' => 'items.store',
...
]
);
