Model function :
class Cart extends Model
{
public static function cart()
{
$id = \Auth::user()->id;
$count = Cart::where('user_id' , $id)->sum('quantity');
return $count;
}
}
But it shows Trying to get property 'id' of non-object at view page. Please help me how to solve this?
You can use Auth::User()->id; to get current user id.
You have multiple options:
1) use Illuminate\Support\Facades\Auth;
Auth::user()->id;
2) auth()->user()->id;
3) if (Auth::check())
{
//check if a user is logged in, now get the id
Auth::user()->id
}
4) Auth::id();
Try this
pass $userId rather then auth()
it's not good practice to call auth function inside model
because auth is applyed on controller so from controller you can send auth user id
model will also work but good practice is keep auth inside your controller
class Cart extends Model
{
public static function cart($userId)
{
$count = Cart::where('user_id' , $userId)->sum('quantity');
return $count;
}
}
``
Your error not depends to :
$id = \Auth::user()->id;
Its ok. Your problem is ther you call record of Cart in this line:
$count = Cart::where('user_id' , $id)->sum('quantity');
Use dd($id) and dd($count) to see that probably there is no Cart record with that feature in database. :)
