So i have a problem that has been bugging me for a few days now. I want to display my posts on my homepage that is already displaying on my other pages. I think i have found why the information is not displaying and this is due to the Routes of the page. The view is looking fine and works correctly, however my controllers are the issue:
Web.php
Route::get('/', 'PageController#index');
Route::get('/welcome', 'HomeController#index1');
Route::get('/services', 'PageController#services');
Route::get('/register', 'PageController#register');
Route::get('/Create', 'PageController#Create');
Route::get('/search', 'PageController#search');
Route::get('/payment', 'PageController#Payment');
Route::resource('posts', 'PostsController');
Route::resource('search', 'SearchController');
Route::resource('reviews', 'ReviewsController');
Route::resource('postings', 'HomeController');
HomeController.php
public function index()
{
return view('home');
}
public function index1()
{
$postings = Post::all();
return view('Pages.welcome', compact('postings'));
}
Welcome.blade.php
#if(count($postings) > 1)
#foreach($postings as $post)
<h2>{{$post->title}}</h2>
#endforeach
#else
</p>no posts found</p>
#endif
The issue is in my WEB.PHP. PageController#index directs the page to the homepage, with HomeController being the controller that holds index. I then decided to create a function within that HomeController that allows me to display posts, however i keep getting error 'undefined error'. To conclude how would i insert a function in an existing controller that already has index.
You don't have $postings variable in your view, don't access it. This does not mean you can not do what you want.
You can abuse how if statements are resolved. If you have && operator in your if statement it will not check secondary conditions if first condition fails.
Will fail
#if ($postings)
Will work
#if (false && $postings)
To check if a variable is present without accessing it, you can use isset(), that is a PHP function. This will create the preferred statement that will not access $postings if it is not there. So try with the following code.
#if(isset($postings) && count($postings) > 1)
#foreach($postings as $post)
<h2>{{$post->title}}</h2>
#endforeach
#else
</p>no posts found</p>
#endif

So I have a little project, in it, there's the possibility to upload banners images to be shown on the main page. All the stuff related to the DB are already created and the option to create a banner is working, it creates the banner and then stores the image on the DB for use later. Now I'm trying to work on an edit function so I can change the description under the bannners. I have an Edit route in my controller which returns a view where I edit said banner then it calls the update function on the controller. But no matter what I put here, I'm always getting the Missing Required Parameters error once I try to Save the edit and open my controller through the Update function. Here's the code as it is now:
The route definition:
Route::resource('banner', 'BannerController');
The edit function on my controller:
public function edit($id)
{
return view('admin/edit-banners',['id'=>$id]);
}
The update function has not been implemented because I always start with a dd() function to check if everything is working fine:
public function update(Request $request, $id)
{
dd($request);
}
And here's the form line in my edit view that is trying to call the update route:
<form class="card-box" action="{{ route('banner.update',[$banner]) }}">
I also added this at the beginning of the view to store the data from the DB into a variable:
#php
use\App\Banner;
$banner = Banner::where('id','=',$id)->get();
#endphp
The $banner variable contains all the information on the banner being edited, and I can get the new description at the controller with the $request variable, so I honestly don't know what should I put here as parameters, any ideas?
The $banner variable is not a Model instance, it is a Collection.
Adjust your controller to pass this to the view instead of dong the query in the view:
public function edit($id)
{
$banner = Banner::findOrFail($id);
return view('admin.edit-banners', ['banner' => $banner]);
}
You could also use Route Model Binding here instead of doing the query yourself.
Remove that #php block from your view.
The form should be adjusted to use method POST and spoof the method PUT or PATCH (as the update route is a PUT or PATCH route) and you should adjust the call to route:
<form class="card-box" action="{{ route('banner.update', ['banner' => $banner]) }}" method="POST">
#method('PUT')
If you include $id in your function declaration then when you call the route helper it expects you to give it an id parameter. Try with
<form class="card-box" action="{{ route('banner.update',['id' => $id]) }}">
You should be able to retrieve the form data just fine form the $request variable. More info here.
The code below should be the error source. $banner variable then is an array but the update function accept object or id.
#php
use\App\Banner;
$banner = Banner::where('id','=',$id)->get();
#endphp
You should try to replay this code by this one...
#php
use\App\Banner;
$banner = Banner::find($id);
//you should put a dd here to view the contain of $banner if you like
#endphp
Hop it help...
Hello im trying to get information about user on my view.
Here is my UserController
public function getUser(Request $request, $id)
{
$user = User::findOrFail($id);
return view('admin.user', ['user' -> $user]);
}
here is my web.php
Route::get('admin/user/{id}', "UsersController#getUser");
and my user view
#extends('admin.layouts.app')
#section('contents')
<h1>User {{ $user }} </h1>
#endsection
I am trying to display user information in this view, like name etc, but im recives 404
Not Found page. What im doing wrong. Im using Laravel 6
404 error may refer to a User not being found, since you have a findOrFail() query. It may have nothing to do with your routes.
Just double check with:
php artisan route:list
just to make sure the route is being registered correctly.
I think you firstly use any prefix for this route.For this it will give you an error.To check route list.
php artisan route:list
it will give you all route.
And Here you don't need (Request $request) because here you just need the id.it not the problem..i give you just this suggestion
public function getUser($id)
{
$user = User::findOrFail($id);
return view('admin.user', ['user'=> $user]);
}
why you use '-> ' you should use '=>'
I'm trying to receive data on a sidebar that is included in the blade template but i'm not getting any data delivered. I've tried adding #include('admin.sidebar',['message_counter' => $message_counter]) and in the sidebar view show as {{$message_counter}}. I'm getting a Undefined variable: message_counter.
My router:
Route::get('/admin/sidebar', [
'uses' => 'MessagesController#counter',
'as' => 'admin.sidebar'
]);
My controller
use App\Message;
public function counter()
{
$message_counter = Message::where('status', 0)->get();
return view('admin.sidebar')->with('message_counter', $message_counter);
}
My View
<span class="menu-collapsed">Messages <span class="badge badge-pill badge-primary ml-2"> {{$message_counter}} </span></span>
What i ultimately intend to do is to show the amount of unread messages in the sidebar of the administrator backend, which is #includein every page.
It may be because i'm accessing two different controllers everytime I enter any page on the admin backend.
I've looked into Including Sub-Views but i'm probably missing something silly or not understanding some key concept, help is appreciated!
Thank you!
Note: I think this is inconvenient and unrecommendable. This is just to answer the question, you can scroll down to see other answers or approach.
Controller
public function counter()
{
$message_counter = Message::where('status', 0)->get();
return view('admin.sidebar');
}
View
#php
$message_counter = App\Message::where('status', 0)->get();
#endphp
Messages <span class="badge badge-pill badge-primary ml-2"> {{$message_counter}} </span></span>
You can try like this way
In Route:
Route::get('/admin/sidebar', 'MessagesController#counter');
In Controller
use App\Message;
public function counter()
{
$message_counter = Message::where('status', 0)->get();
return view('admin.sidebar', compact('message_counter));
}
And your view is ok.. Try this and if it is not working please let me know....
With a View Composer: add this to App\Providers\AppServiceProvider#boot()
View::composer('admin.sidebar', function ($view) {
$message_counter = Message::where('status', 0)->get();
$view->with([''message_counter' => $message_counter]);
});
I'm developing an application with Laravel 5.8. In my application, I have a controller that handles backend articles, and it works. I want to display my user-side information in such a way that a user can click on a link and see the detail of an article. For that, I have created a new controller a with a new namespace for the function show my redirection of navigation in different page does not focus that it is en route or URL with Laravel 5.8. Below is the function.
namespace App\Http\Controllers\Cybernaut;
use App\History;
use App\Http\Controllers\Controller;
class HistoryController extends Controller
{
public function show($id)
{
$history = History::find($id);
return view('show_history', compact('history'));
}
}
At the level of the home page I wanted to have my links like these:
<li><a data-hover="history" href="{{route('history.show',$history→id)}}"><span>history</span></a></li>
Error
ErrorException (E_ERROR) Property [id] does not exist on this
collection instance. (View:
C:\laragon\www\venome\resources\views\layouts\partial\header.blade.php)
And here is the route used for the show function.
Route::group(['namespace'=>'cybernaut'], function (){
Route::get('/history/{slug}','HistoryController#show')->name('history.show');
});
Try after modifying the thing I have these at the route level now.
Route::get('/', 'FrontController#index')->name('index');
Auth::routes();
Route::get('/home', 'HomeController#index')->name('home');
Route::get('/admin/dashboard', 'DashboardController#index')->name('admin.dashboard');
Route::group([], function () {
Route::get('/history', 'HistoryController#index')->name('history.index');
Route::get('/history', 'HistoryController#create')->name('history.create');
Route::get('/history/edit', 'HistoryController#update')->name('history.update');
Route::get('/history', 'HistoryController#destroy')->name('history.destroy');
});
Route::group(['namespace' => 'cybernaut'], function () {
Route::get('/history/{history}', [
'as' => 'show',
'uses' => 'HistoryController#show'
]);
});
At the level of the homepage I wanted to put my link like those here now;
#foreach($history as $history)
<li><a data-hover="history" href="{{url('/history/'.$history->id)}}"><span>history</span></a></li>
#endforeach
I have this error now:
Trying to get property 'id' of non-object (View:
C:\laragon\www\venome\resources\views\layouts\partial\header.blade.php)
I want an internaut to be able to navigate between the pages.
You have a conflict of variables on your homepage.
#foreach($history as $history)
should be
#foreach($histories as $history)
where $histories is filled in in your FrontController.
$histories = History::all();
When actually getting your single history object, I agree with Sapnesh's answer that you best doublecheck whether or not the object actually exists.
The error occurs because find() returns NULL when a model is not found.
find($id) takes an id and returns a single model. If no matching model
exist, it returns null.
findOrFail($id) takes an id and returns a single model. If no matching
model exists, it throws an error.
In your show() method,
Change:
$history = History::find($id);
To:
$history = History::findOrFail($id);
I want to pass custom validation messages to my view using a custom request when storing a role.
I have create a new Request called StoreRoleRequest
<?php
namespace App\Http\Requests;
use App\Http\Requests\Request;
use Illuminate\Contracts\Validation\Validator;
class StoreRoleRequest extends Request
{
public function authorize()
{
return true;
}
public function rules()
{
return [
'name' => 'required'
];
}
protected function formatErrors(Validator $validator)
{
return $validator->errors()->all();
}
public function messages()
{
return [
'name.required' => 'the name of the Role is mandatory',
];
}
}
And then pass this custom Request to my store function in the RoleController like this:
public function store(StoreRoleRequest $request)
{
Role::create($request->all());
return redirect(route('role.index'));
}
I have a view that show the create role form where the validation seems to work properly but without showing me error even if i call them into the view like this:
{!! Former::open()->action(route('role.store')) !!}
#if (count($errors->all()))
<div class="alert alert-danger">
#foreach ($errors->all() as $error)
<li>{{ $error }}</li>
#endforeach
</div>
#endif
{!! Former::text('name')->label('Groupe name') !!}
{!! Former::text('display_name')->label('Displayed name') !!}
{!! Former::text('description')->label('Description') !!}
{!! Former::actions( Button::primary('Save')->submit(),
Button::warning('Clear')->reset() ,
Button::danger('Close')->asLinkTo('#')->withAttributes(['data-dismiss' => 'modal'])
)!!}
{!! Former::close() !!}
Has anyone an idea why the errors doesn't appear into the view ? am I looping something inside the custom Request ?
EDIT
NB: Even in the login and the registration form the errors doesn't appear anymore.
In this case i have change my middlware that was pointed to web ['middleware' => ['web'] to this:
Route::group(['middleware' => []], function ()
{
// other routes
Route::resource('role', 'RoleController');
});
and all my errors displayed perfectly.
have you locate the root cause about this issue ?
After your question update it seems, you have newer version of Laravel application (don't confuse it with Laravel framework).
To verify this, open file app/Providers/RouteServiceProvider.php and verify method what's the content of map method. In case it launches mapWebRoutes it means that you have 5.2.27+ application which applies web group middleware automatically.
In case web middleware is applied automatically you shouldn't apply web middleware in your routes.php file because it will cause unexpected behaviour.
So you should either remove web middleware from your routes.php in case you have mapWebRoutes defined in your RouteServiceProvider class or you can modify your RouteServiceProvider class to not apply web group middleware automatically. It's up to you which solution you choose.
Just for quick reference:
RouteServiceProvider for Laravel application 5.2.24
RouteServiceProvider for Laravel application 5.2.27
Try to ask if errors exists by this way:
#if($errors->any())
// Your code
#foreach($errors->all() as $error)
<li>{{ $error }}</li>
#endforeach
// More code
#endif
Also remove the formatErrors function from the request... You don't need it...
The function messages() is responsible for returning your custom messages...
Regards.
