Membuat link daftar order ke WhatsApp di Laravel

public function checkout(Request $request)
    {
        $request->validate([
            'name' => 'required',
            'alamat' => 'required',
            'wa' => 'required',
            'kota' => 'required'
        ]);
        $product = Product::findOrFail($request->productId);

        $name = rawurlencode($request->name);
        $alamat = rawurlencode($request->alamat . ", Kecamatan " . $request->kota);
        $productname = rawurlencode($product->name);
        $price = rawurlencode($product->price);
        $linkproduct = url()->previous();

        $url     = "https://api.whatsapp.com/send?phone=6281239276070&&text=Nama%20%3A%20$name.%0ANo.Wa%20%3A%20$request->wa.%0A*Alamat*%20%3A%20$alamat.%0A%0A%0ANama%20Produk%20%3A%20$productname.%0AHarga%20%3A%20Rp." . number_format($price) . ".%0A%0A%0AURL%20%3A%20" . $linkproduct;
        return redirect()->to($url);
    }

contoh lain:

        $order->update();

        $selectPayment = $request->selectPayment;
        $payment = new Payment;
        $payment->order_id = $order->id;
        $payment->method = "manual";

        $payment->va_number = "";
        $payment->vendor_name = $selectPayment;

        // Membuat array dari atribut-atribut payment

            'vendor_name' => $payment->vendor_name,
            'transaction_token' => $payment->transaction_token,
        ];

        // Mengonversi array ke JSON dan menyimpannya di dalam kolom payloads
        $payment->payloads = json_encode($paymentData);
        $payment->save();

        $orderDetailString = "Assalamuaikum Wr. Wb.\nSaya Ingin Order produk berikut:\n";
        foreach ($orderdetail as  $index => $detail) {
            $orderDetailString .= "*(" . ($index + 1) . ") - Nama Produk: " . $detail->products->nama . "*\n"; // Sesuaikan dengan nama kolom yang sesuai
            $orderDetailString .= "*- Qty: " . $detail->qty . "*\n";
            $orderDetailString .= "*- Subtotal: Rp. " . $detail->jumlah_harga . "*\n\n";

        // Menambahkan informasi total ke string
        $orderDetailString .= "*Total = Rp. " . $order->grand_total . "*\n";

        $orderDetailString .= "*Atas Nama: " . $profil->nama . "*\n";
        $orderDetailString .= "*Alamat: " . $address->alamat_detail . "*\n";

        // Membuat URL dengan informasi order detail
        $url = urlencode($orderDetailString);
        // Mengambil nomor WhatsApp dari .env
        $whatsappNumber = env('WHATSAPP_NUMBER');

        // Membuat URL WhatsApp dengan nomor yang diambil dari .env
        $baseurl = "https://wa.me/{$whatsappNumber}?text=" . $url;
        return redirect($baseurl);

contoh lain yang lebih baik:

    public function processWhatsApp()
    {
        if (\Cart::isEmpty()) {
            return redirect()->route('cart.index');
        }

        \Cart::removeConditionsByType('shipping');

        $items = \Cart::getContent();
        $message = "Halo, saya ingin membeli produk:";
        foreach ($items as $item) {
            $message .= "\r\n*" . "$item->name*" . "\r\n*" . "Jumlah:* $item->quantity" . "\r\n*" . "Harga:* $item->price" . "\r\n--------------------------";
        }
        $whatsappLink = "https://api.whatsapp.com/send?phone=6282268591403&text=" . urlencode($message);

        return Redirect::away($whatsappLink);
