THis is my controller file which i try to display data of particular user which is loggin at the time
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Stock;
use Auth;
class StockController extends Controller
{
/**
* Display a listing of the resource.
*
* #return \Illuminate\Http\Response

public function index()
{
$stocks = Stock::all()->toArray();
return view('stock.index', compact('stocks'));

Answer 1

there are 2 ways. first is like #Keepon said: create a relationship between the user and the stock table
2:
$user = Auth::user();
$stocks = Stock::where('user_id','=',$user->id)->get();

Answer 2

Please change you index function
/**
* Display a listing of the resource.
*
* #return \Illuminate\Http\Response
*/
public function index()
{
$stocks = Stock::where('user_id', Auth::id())->get();
return view('stock.index', compact('stocks'));
}
And than in your blade
#foreach($stocks as $stock)
<tr>
<td>{{$stock->product_name}}</td>
<td>{{$stock->product_code}}</td>
<td>{{$stock->details}}</td>
<td>{{$stock->price}}</td>
<td>{{$stock->cost}}</td>
<td>{{$stock->quntity}}</td>
<td ></i>
</td>
<td>
<form id="my_form" method="post" class="delete_form" action="{{action('StockController#destroy', $stock->id)}}">
{{csrf_field()}}
<input type="hidden" name="_method" value="DELETE" />
<i class="fa fa-trash"></i>
</form>
</td>
</tr>
#endforeach

Answer 3

The best practice is to make a MODEL RELATIONSHIP.
To make a user and stocks relationship you need to determine what relationship would you build.
In this case I will build a relationship base on what I under stand a One To Many relationship
DATABASE
Stocks Migration
Schema::create('users', function (Blueprint $table) {
$table->bigIncrements('id');
$table->unsignedBigInteger('user_id');
...
$table->timestamps();
$table->foreign('user_id')->references('id')->on('users')->onDelete('cascade');
});
It should be look like the above code.
Then in your model you can connect the relationship of user and stocks
MODEL
User Model
class User extends Authenticatable
{
use Notifiable;
/**
* The attributes that are mass assignable.
*
* #var array
*/
protected $fillable = [
'name', 'email', 'password',
];
/**
* The attributes that should be hidden for arrays.
*
* #var array
*/
protected $hidden = [
'password', 'remember_token',
];
/**
* The attributes that should be cast to native types.
*
* #var array
*/
protected $casts = [
'email_verified_at' => 'datetime',
];
public function stocks() {
return $this->hasMany(Stock::class);
}
}
Stock Model
class Stock extends Model
{
protected $guarded = [];
public function user() {
return $this->belongsTo(User::class);
}
}
Then you can query on your controller the user stocks.
CONTROLLER
Stocks Controller
public function index() {
$stocks = auth()->user()->stocks;
return view('index', compact('stocks'));
}

Answer 4

add this function in User Model
public function stocks() {
return $this->hasMany(Stock::class);
}
in Stocks Controller
public function index()
{
$stocks = auth()->user()->stocks;
return view('stock.index', compact('stocks'));
}
in index.blade.php
#foreach($stocks as $row)
<tr>
<td>{{$row['product_name']}}</td>
<td>{{$row['product_code']}}</td>
<td>{{$row['details']}}</td>
<td>{{$row['price']}}</td>
<td>{{$row['cost']}}</td>
<td>{{$row['quntity']}}</td>
<td ></i>
</td>
<td>
<form id="my_form" method="post" class="delete_form" action="{{action('StockController#destroy', $row['id'])}}">
{{csrf_field()}}
<input type="hidden" name="_method" value="DELETE" />
<i class="fa fa-trash"></i>
</form>
</td>
#endforeach
