How to Show Data After Login in Laravel

Tags: , , ,

After successfully login from auth, I wan to show the data from database. But I got an error like this.

Undefined variable: barangs (View: C:xampp7htdocsexample-appresourcesviewsbarang.blade.php) in c1126675c0e1af0f5c253b69d8a8d64d968d987a.php line 188

and this is the login controller

    class loginController extends Controller
   function auth(Request $req){

        $username = $req->input('your_name');
        $password = md5($req->input('your_pass'));

        $chekLogin = DB::table('user')->where(['username'=>$username,'password'=>$password])->get();
        if(count($chekLogin) > 0 ){
         return view('barang');
        else {
           echo " Login Failed, Wrong Data";



and this is my barangController

    class barangController extends Controller
   public function data(){

        $barangs = DB::table('barang')->get();
        //return $barangs;
        return view('barang',['barangs'=>$barangs]);

this is my barang.blade.php

<div class="x_content">
                  <p class="text-muted font-13 m-b-30">
                   Info Barang
                  <table id="datatable" class="table table-striped table-bordered">
                        <th>Kode Barang</th>
                        <th>Nama Barang</th>
                      @foreach ($barangs as $item)
                        <td><a href="" class="btn btn-primary btn-sm"><i class="fa fa-pencil"></i></a>

and this is my route

Route::get('/', function () {
    return view('index');

Route::get('databarang', 'barangController@data');

please help me,I dont know why barang is not defined in here, may I forgot to add something? Thankyou before


The error is because you’re not including the barangs data when you return your view in the auth function.

Instead of returning a view from your auth, redirect the user:

if(count($chekLogin) > 0 ){
    return redirect(url('databarang'));

What this will do is redirect your user to the route which then returns your view('barang') but includes the missing barangs data.
