date('d-m-Y', strtotime($articles->from_date));

I am trying to execute simple CRUD operation using laravel. but it gives an error code 500 , when I try to fetch data from table either by laravel framework as well as with plain PHP.
Here is my controller class.
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\BookModel;
use \DB;
class AdminController extends Controller
{
function getItems()
{
$data = DB::select('select * from book');
$data = BookModel::all();
echo($data);
return compact('data');
}
}
axiom , which is been used. ---> "https://unpkg.com/axios/dist/axios.min.js"
Model Class:
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class BookModel extends Model {
protected $table = "book";
public $timestamps = false;
}
It is returning no result from the table.
It worked after I changed my controller to
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\BookModel;
use \DB;
class AdminController extends Controller
{
function getItems()
{
$data = BookModel::all();
return $data;
}
}
But it was giving null result when I was doing something like below
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\BookModel;
use \DB;
class AdminController extends Controller
{
function getItems()
{
$data = BookModel::all();
return view('admin')->withTasks($data);
}
}
Can someone explain why it was not working earlier?
Anyways , Thanks everyone for your help.
Cheeeeeeeeerrsssss!!!!!!!
You need to add response() to return data without view.
Like below the code returns the JSON data from your BookModel that sometimes we need through the ajax request like axios.
class AdminController extends Controller
{
function getItems()
{
$data = BookModel::all();
return response()->toJson($data);
}
}
With view you can do the following:
class AdminController extends Controller
{
function getItems()
{
$data = BookModel::all();
return view('admin', compact('data'));
}
}
Where you can access the BookModel data through $data variable in your admin.blade.php
I'm working on the Excel exports in my laravel project. Now I get this error:Class 'App\Export\UsersExport' not found I made 3 others and they worked. This one doesn't and I can't seem to figure out what causes this error. I'm using "Maatwebsite's Laravel-Excel".
My exports controller:
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
//exports
use App\Export\UsersExport;
use App\Exports\StudyClassExport;
use App\Exports\EducationsExport;
use App\Exports\IntakesExport;
use Maatwebsite\Excel\Facades\Excel;
use App\Http\Controllers\Controller;
class ExportsController extends Controller
{
public function users()
{
return Excel::download(new UsersExport, 'gebruikers.xlsx');
}
public function educations()
{
return Excel::download(new EducationsExport, 'opleidingen.xlsx');
}
public function classes()
{
return Excel::download(new StudyClassExport, 'klassen.xlsx');
}
public function intakes()
{
return Excel::download(new IntakesExport, 'intakes.xlsx');
}
}
UsersExport:
<?php
namespace App\Exports;
use App\User;
use Maatwebsite\Excel\Concerns\FromCollection;
class UsersExport implements FromCollection
{
/**
* #return \Illuminate\Support\Collection
*/
public function collection()
{
return User::all();
}
}
I have no idea what causes this error. The others work but this one doesn't
You have a typo:
use App\Export\UsersExport;
use App\Exports\UsersExport;

I'm trying to display data in my views in Laravel 5.6.9, but I keep getting this error.
Error
Code snippet
TodosController
<?php
namespace App\Http\Controllers;
use\App\Todo;
use Illuminate\Http\Request;
class TodosController extends Controller {
public function index()
{
$todos = Todo::all();
return view('todos')->with('todos', '$todos');
}
}
Browser gave this error
<div class="title m-b-md">
<?php $__currentLoopData = $todos; $__env->addLoop($__currentLoopData); foreach($__currentLoopData as $todo): $__env->incrementLoopIndices(); $loop = $__env->getLastLoop(); ?>
<?php echo e($todo->todo); ?>
<br>
In your controller, you must remove the single quotes around the $todos variable:
return view('todos')->with('todos', $todos);
You should change your controller code like:
namespace App\Http\Controllers;
use App\Todo;
use Illuminate\Http\Request;
class TodosController extends Controller
{
public function index() {
$todos = Todo::get();
return view('todos',compact('todos'));
}
}
A wiser approach to the situation would be to use compact. Compact is a PHP function that creates an array containing variables and their values.
When returning a view, we can easily use compact to pass some data.
One can use compact like this:
$data = Data::all();
return view('viewname')->with(compact('data'));
So in your script:
<?php
namespace App\Http\Controllers;
use\App\Todo;
use Illuminate\Http\Request;
class TodosController extends Controller {
public function index()
{
$todos = Todo::all();
return view('todos')->with(compact('todos'));
}
}
If you wish to do it the way you tried it in the first place, you should do it like this:
<?php
namespace App\Http\Controllers;
use\App\Todo;
use Illuminate\Http\Request;
class TodosController extends Controller {
public function index()
{
$todos = Todo::all();
return view('todos')->with('todos', $todos);
}
}
Mind that there are no apostrophes around the variable $todos.
I'm following the Laracasts series and have run into an issue on the episode Laravel 5.4 From Scratch: Route Model Binding.
Laravel version:
Laravel Framework 5.6.13
The error:
Class App\Http\Controllers\Panel does not exist
This shows on both the /panel and /panel/1 pages
App\Http\Controllers\PanelController.php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
// Code works if I uncomment below line, and change the show function to "show($panel)"
//use App;
class PanelController extends Controller
{
public function index()
{
$panels = Panel::all();
return view('panel/index', compact('panels'));
}
public function show(Panel $panel)
{
return $panel;
return view('panel/show', compact('panel'));
}
}
routes/web.php
// Main panel view
Route::get('/panel', 'PanelController#index');
// Individual panel view
Route::get('/panel/{panel}', 'PanelController#show');
App/Panel.php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Panel extends Model
{
public static function activePanels()
{
return static::where('status', 1)->get();
}
}
Add this line in panel controller before the class
use App\Panel;
You need to add use App\Panel; to top of class
Or call it by full namespace $panels = App\Panel::all();
You don't included your model to class.
Add App\Panel to main include section:
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Panel;
class PanelController extends Controller
{
public function index()
{
$panels = Panel::all();
return view('panel/index', compact('panels'));
}
public function show(Panel $panel)
{
return $panel;
return view('panel/show', compact('panel'));
}
}
or load model in your class method manually:
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class PanelController extends Controller
{
public function index()
{
$panels = App\Panel::all();
return view('panel/index', compact('panels'));
}
public function show(Panel $panel)
{
return $panel;
return view('panel/show', compact('panel'));
}
}
I have following function and want to call it from view. Basically i want to put all common functions in one file. I am not sure where to create that file and how to call it inside controller and view.
<?php namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use DB;
class CommonController extends Controller {
public function BytesToMB($bytes=0)
{
if(empty($bytes))
return 0;
$kb = ceil($bytes/1024);
$mb = ceil($kb/1024);
return $mb;
}
}
So far i have created CommonController.php in app/Http/Controllers and put above function in it.
Then in other controller i have tried to call it following way:
use App\Http\Controllers\Common;
class SongsController extends Controller {
public function index($id)
{
echo Common::BytesToMB('7012187');
}
}
But i am getting error:
Class 'App\Http\Controllers\Common' not found
Ok, new try. You missed to use the complete class name and add the static keyword:
<?php
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use DB;
class CommonController extends Controller {
public static function BytesToMB($bytes=0)
{
if(empty($bytes))
return 0;
$kb = ceil($bytes/1024);
$mb = ceil($kb/1024);
return $mb;
}
}
And then:
<?php
namespace App\Http\Controllers;
// You do not need to define this, if you are in the same namespace
use App\Http\Controllers\CommonController;
class SongsController extends Controller {
public function index($id)
{
echo CommonController::BytesToMB('7012187');
}
}
Another and more OOP solution is to use the function from the parent class:
<?php
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use DB;
class CommonController extends Controller {
protected function BytesToMB($bytes=0)
{
if(empty($bytes))
return 0;
$kb = ceil($bytes/1024);
$mb = ceil($kb/1024);
return $mb;
}
}
And then:
<?php
namespace App\Http\Controllers;
// You do not need to define this, if you are in the same namespace
use App\Http\Controllers\CommonController;
class SongsController extends CommonController {
public function index($id)
{
echo $this->bytesToMB('7012187');
}
}
