在asp.net中發送購物車總量變量到PayPal

2013-04-03 33 views

當將Paypal與自定義內置系統集成時，我設法設置它來發送設置值，例如25英鎊，但是不是籃子中的變量，例如， 「GrandTotal」，這是依賴於什麼客戶已經進入購物車（我已經創建了自己的車。）在asp.net中發送購物車總量變量到PayPal

請參考下面的代碼：

<%@ page language="C#"%> 
<%@ Register TagPrefix="webxelcart" Namespace="WebXelCart" Assembly="WebXelCart" %> 
<script runat="server"> 

void btnCheckout_Click(object sender, System.EventArgs e) 
{ 
WriteToDB1.Save(); 
} 

void WriteToDB1_RecordInserted(object sender, WebXelCart.RecordInsertedEventArgs e) 
{ 
Cart1.OrderID = e.Identity; 
SaveOrder1.Save(); 
} 

    protected void Page_Load(object sender, EventArgs e) 
    { 

    } 
</script> 

<!doctype html> 
<head> 
<meta charset="utf-8"> 
<meta name="viewport" content="width=device-width, initial-scale=1"> 


<script runat="server"> 
    void Cart1_Load(object sender, System.EventArgs e) 
    { 
    if(Cart1.GrandTotal > 100){Cart1.CarriageCost = 0;} 
    else{Cart1.CarriageCost = 15;} 
    } 
    </script>

     }

任何關於如何把'GrandTotal'變量的幫助，並將其發送到貝寶將不勝感激。

你不能在ASP.Net頁面創建多個form tag（除非IFRAME），因爲ASP.Net只允許在一個頁面一個表單標籤。

你想在後面的代碼中類似這樣。它基本上收集用戶輸入的金額和數量，然後將其發回PayPal。

protected void btnCheckout_Click(object sender, EventArgs e) { 

string paypalUrl = IsTestMode ? 
    "https://www.sandbox.paypal.com/us/cgi-bin/webscr" : 
    "https://www.paypal.com/us/cgi-bin/webscr"; 

var builder = new StringBuilder(); 

builder.Append(paypalUrl); 

builder.AppendFormat("?cmd=_xclick&business={0}", 
    HttpUtility.UrlEncode([email protected])); 

builder.Append("&lc=US&no_note=0&currency_code=GBP"); 

builder.AppendFormat("&item_name={0}", 
    HttpUtility.UrlEncode(YourItemName)); 

builder.AppendFormat("&amount={0}", AmountTextBox.Text); 

builder.AppendFormat("&return={0}", 
    HttpUtility.UrlEncode("http://mysite.cm/ReturnUrl")); 

builder.AppendFormat("&cancel_return={0}", 
    HttpUtility.UrlEncode("http://mysite.cm/CancelUrl")); 

builder.AppendFormat("&undefined_quantity={0}", QuantityTextBox.Text); 

HttpContext.Current.Response.Redirect(builder.ToString()); 

}
