如何让用户无法将产品添加到来自不同商店的购物车会话？

Question

所以，我想做 if else 语句，如果 $cart 会话有不同的 sponsor_id 值，用户不能从另一个 sponsor_id

添加产品

这是我的 CartController

public function addToCart(Request $request, $id)
{
    $cart = session("cart");
    $produk = Produk::detail_produk($id);

    if (isset($cart[$id])) {
        $cart[$id]["qty"]++;
        session()->put('cart', $cart);
    } else {
        $cart[$id] = [
            "sponsor_id" => $produk->sponsor_id,
            "nama_produk" => $produk->nama_produk,
            "harga_produk" => $produk->harga_produk,
            "berat" => $produk->berat,
            "gambar" => $produk->gambar,
            "qty" => $request->qty
        ];
    }
    session(["cart" => $cart]);
    return redirect()->back()->with('success', 'Produk Berhasil dimasukkan ke keranjang !!');
}

因此，用户必须先完成交易，然后才能将另一个 sponsor_id 的产品添加到购物车

我认为这段代码将通过循环之前的产品数据来完成。

public function addToCart(Request $request, $id)
{
    $cart = session("cart");
    $produk = Produk::detail_produk($id);

    if (isset($cart[$id])) {
        $cart[$id]["qty"]++;
        session()->put('cart', $cart);
    } else {
        $num = count($cart);
        if($num > 0){
          $this_sponsor_id = $produk->sponsor_id;
          foreach($cart as $produk_id => $produk_data){
            if($produk_data->sponsor_id != $this_sponsor_id){
              return false;
            }
          }
        }
        $cart[$id] = [
            "sponsor_id" => $produk->sponsor_id,
            "nama_produk" => $produk->nama_produk,
            "harga_produk" => $produk->harga_produk,
            "berat" => $produk->berat,
            "gambar" => $produk->gambar,
            "qty" => $request->qty
        ];
    }
    session(["cart" => $cart]);
    return redirect()->back()->with('success', 'Produk Berhasil dimasukkan ke keranjang !!');
}

我也在想，也许你可以将物品存放在单独的购物车中，按赞助商 ID 分组。然后您可以在结账时单独为正确的商品收费。

public function addToCart(Request $request, $id)
{
    $newcart  = session("cart");
    $produk = Produk::detail_produk($id);
    $newcart = session("newcart");
    if(!isset($newcart[$produk->sponsor_id])){
      $newcart[$produk->sponsor_id] = [];
    }
    if(isset($newcart[$produk->sponsor_id][$id])){
      $newcart[$produk->sponsor_id][$id]["qty"]++;
      session()->put('newcart', $newcart);
    } else {
      $newcart[$produk->sponsor_id][$id] = [
          "sponsor_id" => $produk->sponsor_id,
          "nama_produk" => $produk->nama_produk,
          "harga_produk" => $produk->harga_produk,
          "berat" => $produk->berat,
          "gambar" => $produk->gambar,
          "qty" => $request->qty
      ];
    }
    session(["newcart" => $newcart]);
    return redirect()->back()->with('success', 'Produk Berhasil dimasukkan ke keranjang !!');
}

我的情况变化不大。如果有人和我有同样的问题

public function addToCart(Request $request, $id)
{
    $cart = session("cart");
    $produk = Produk::detail_produk($id);
    $num = count(array($cart));
    if (isset($cart[$id])) {
        $cart[$id]["qty"]++;
        session()->put("cart", $cart);
    } else {
        if ($num > 0) {
            $this_sponsor_id = $produk->sponsor_id;
            foreach ($cart as $produk_id => $produk_data) {
                if ($produk_data["sponsor_id"] != $this_sponsor_id) {
                    return redirect()->back()->with('error', 'Bersihkan Keranjang sebelum Membeli dari Booth Lain');
                }
            }
        }
        $cart[$id] = [
            "sponsor_id" => $produk->sponsor_id,
            "nama_produk" => $produk->nama_produk,
            "harga_produk" => $produk->harga_produk,
            "berat" => $produk->berat,
            "gambar" => $produk->gambar,
            "qty" => $request->qty
        ];
    }
    // dd($cart);
    session(["cart" => $cart]);
    return redirect()->back()->with('success', 'Produk Berhasil dimasukkan ke keranjang !!');
}
