I got an error says undefined variable data referring to my foreach in my blade
so my errors is :
Undefined variable: data (View: C:\Users\adila\Desktop\onlineshop\onlineshop\resources\views\user\product.blade.php)
so this is my blade file :
<div class="latest-products">
<div class="container">
<div class="row">
<div class="col-md-12">
<div class="section-heading">
<h2>Latest Products</h2>
view all products <i class="fa fa-angle-right"></i>
</div>
</div>`enter code here`
#foreach($data as $product)
<div class="col-md-4">
<div class="product-item">
<img src="assets/images/product_06.jpg" alt="">
<div class="down-content">
<h4>{{$product->title}}</h4>
<h6>$ {{$product->harga}}</h6>
<p>{{$product->deskripsi}}</p>
</div>
</div>
</div>
#endforeach
</div>
</div>
</div>
and this is my controller :
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use App\Models\User;
use App\Models\Product;
class HomeController extends Controller
{
public function redirect(){
$usertype = Auth::user()->usertype;
if($usertype=='1'){
return view('admin.home');
}
else{
return view('user.home');
}
}
public function index(){
if(Auth::id()){
return redirect('redirect');
}
else{
$data = Product::all();
return view('user.home',compact('data', $data));
}
}
}
and my Route :
Route::get('/', [HomeController::class, 'index']);
Please help me
Please remove $data from compact() function
return view('user.home',compact('data'));
You passed the variable $data to the view('user.home', compact('data')) but you have an error in the product.blade I think the problem is on the product. blade file. check that file
You error is in the product.blade.php view and in your controller you're returning the home.blade.php view.
You can avoid the Undefined variable error in your product.blade.php adding an isset in your view like this :
#if(isset($data))
#foreach($data as $product)
(...)
#endforeach
#endif

I created a Model, Controller, Factory and dataTable files, but laravel keeps showing me the error $dataTable is undefined
How come? Is it a routing issue or I'm not linking the controller to the blade correctly?
My controller:
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\DataTables\DataEntry\ReportsDataTable;
class ReportsController extends Controller
{
public function index(ReportsDataTable $dataTable)
{
return $dataTable->render("pages.dataEntry.reports.index");
}
}
The Route:
// Data Entry pages
Route::prefix('dataEntry')->name('dataEntry.')->group(function () {
Route::resource('reports', ReportsController::class)->only(['index']);
});
index.blade:
<x-base-layout>
<!--begin::Card-->
<div class="card">
<!--begin::Card body-->
<div class="card-body pt-6">
<!--begin::Table-->
{{ $dataTable->table() }}
<!--end::Table-->
{{-- Inject Scripts --}}
{{ $dataTable->scripts() }}
</div>
<!--end::Card body-->
</div>
<!--end::Card-->
</x-base-layout>
public function index()
{
return ReportsDataTable::all()->render("pages.dataEntry.reports.index");
}
I was trying to show the name who have posted the post. It was working well. But after a few days, It is showing an error (ErrorException Trying to get property 'name' of non-object). I was searching for a solution for the last few days. And I have found laravel 8 introduced jetstream for authentication purposes. But I have already started with the laravel ui.
I have checked the model of mine. But I could not find anything which could solve the problem. Here are my codes.
view

I have a DB with multiple tables. I want to display the DB data on my laravel application. I want to display two tables data on the same page. I have created the model, view, and controller for the app but I am being able to display only one table. I cannot show the other table.
I think I need to define a model with multiple relationships which I am not getting how to do.
My tables are called posts and videos I have nothing on my model. the controller and the view is given below.
Controller
namespace App\Http\Controllers;
use App\Post;
use App\Video;
use Illuminate\Http\Request;
class PostsController extends Controller
{
public function index()
{
$posts = Post::all();
return view('landing')->with('posts', $posts);
}
}
View
#extends('layouts.app')
#extends('layouts.navbar')
#section('title')
Landing Page
#endsection
#section('content')
<main class="py-4">
<div class="container">
<div class="row">
<div class="col-md-8">
<h3>Section 1</h3>
#foreach ($posts as $post)
<ul class="list-group">
<li class="list-group-item">
<a href="/posts/{{ $post->id }}">
{{ $post->title }}
{{ $post->brief }}
{{ $post->body }}
{{ $post->cover_image }}
</a>
</li>
</ul>
#endforeach
</div>
<div class="col-md-4">
<h3>Section 2</h3>
#foreach ($videos as $video)
<ul class="list-group">
<li class="list-group-item">

{{ $video->title }}
</a>

Route on the web.php
<?php
use App\Http\Controllers\PagesController;
use Illuminate\Support\Facades\Route;
Route::get('/', 'PostsController#index');
Route::get('/', 'VideosController#index');
Route::get('/posts/{post}', 'PostsController#show');
Route::resource('posts', 'PostsController');
Route::resource('videos', 'VideosController');
Auth::routes();
Controller for videos data table
<?php
namespace App\Http\Controllers;
use App\Video;
use Illuminate\Http\Request;
class VideosController extends Controller
{
public function index()
{
$videos = Video::all();
return view('landing')->with('videos', $videos);
}
}
On this code I see this problem
If I remove the route for videos on my web.php I could see posts data.
So how could I display both the posts and the videos data at the same time?
Pass both Model together :
<?php
namespace App\Http\Controllers;
use App\Video;
use App\Post;
use Illuminate\Http\Request;
class VideosController extends Controller
{
public function index()
{
$videos = Video::all();
$posts = Post::all();
return view('landing', compact('videos','posts'));
}
}
public function profile($id)
{
$id = Crypt::decrypt($id);
$measurements = DB::select( DB::raw("SELECT * FROM measurements WHERE custom_id = '$id'") );
$customers = DB::table('customers')->where('customer_id', '=', $id)->get();
return view('measurements.profile', compact('measurements','customers'));
}
Could someone let me know why I get this error:
"Undefined variable: listings (View: \app\views\pages\listings.blade.php)"
Controller
class ListingsController extends BaseController {
public function showListings() {
$listings = Listing::paginate(10);
return View::make('pages.listings', $listings);
}
}
View
<div class="container">
<div id="main">
<div class="row">
<div class="span9">
<h1 class="page-header">Listings</h1>
#foreach($listings as $listing)
{{ $listing->address }}
#endforeach
</div>
</div>
</div>
</div>
#include('includes.footer')
Try doing like this:
return View::make('pages.listings')->with('listings', $listings);
or
return View::make('pages.listings', array('listings' => $listings));
or even
return View::make('pages.listings', compact('listings'));
