    if($order && $ord){
    $order->notify(new orderSuccessfullNotification($ord->orderNumber,$bookgetter1,$bookgetter2));
    //Here i want to update my books database cart field values should be 0
    //Books::where('cart')->values('0);
    }
      return response()->json(['message'=>'order created successfully','orderID'=>$ord->orderNumber]);
  }



  }

Answer 1

you simply use update query inside if condition

if($order && $ord){
    $order->notify(new orderSuccessfullNotification($ord->orderNumber,$bookgetter1,$bookgetter2));
  
    ModelsBooks::Where('cart','1')->update((['cart'=>'0']));
  }

Answer 2

You can do this through Eloquent:

ModelsBooks::where('cart','1')->update(['cart'=>'0']);

Or DB Query Builder:

DB::table('models_books')->where('cart', 1)->update(['cart' => '0']);

Answer 3

You can try to use Laravel Mass Updates:

ModelsBooks::where('id',1)->update(['cart'=>0]);

Make sure the cart field in Books Model is included in your $fillable

class Books extends Model
{
 /**
  * The attributes that are mass assignable.
  *
  * @var array
  */
  protected $fillable = ['cart'];
}

Update:

Credit to the Accepted Answer:

ModelsBooks::where('id',1)->update((['cart'=>0]));

Answer 4

First solution its simple just get the model whichever you want

$book = Book::where("condition")->first();
$book->fill(['book_price'=>25 // just example])
$book->update();

Second If you want to create then you could use updateorcreate method simply
