This is my Controller...

public function Addtocart(Request $request){ $p_id = $request['id']; $product = Products::find($p_id); $quantity = $request['quantity']; Cart::add(array( 'id' => $p_id, 'name' => $product->title, 'price' => $product->price, 'qty' => $quantity, 'image' => $product->image )); echo " alert('good'); "; return redirect('/admin/store/cart')->with('message', 'Product added to Cart');

}

public function cart(){
    $cart = Cart::content();
    return view('/admin/store/cart', ['products' => $cart]);
}

public function Removeitem($id){
    $item = Cart::search($id);
    Cart::remove($item);
    return redirect()->back()->with('message', 'Product deleted from Cart');

}
