Question

我在第一页上有一个登录表单供用户登录，在登录表单上我有3个文本字段，即电子邮件，密码和代码。当用户输入正确的凭据并输入其代码时，登录将成功。我在第二页上所做的是使用Request.Form（＆＃34; Code＆＃34;）请求用户输入的代码，我将其分配给第2页的文本字段。但是当你输入正确的文件并使用代码时，我无法在文本字段中收到第2页上的代码。

我熟悉此代码，因为它是Dreamweaver＆＃34;登录用户＆＃34;服务器行为。您无法通过＆＃34; Request.Form＆＃34;来获取该代码。因为登录不是将登录数据发布到下一页。

使用此代码时会发生什么情况：创建会话"MM_Username"和"MM_UserAuthorization"（如果您使用用户级别）。

你可以做什么（我为我的许多网站做了这个），如果通过在设置Session("MM_Username")之后添加此行，登录有效，它会为你的代码创建一个额外的会话/ p>

 If Not MM_rsUser.EOF Or Not MM_rsUser.BOF Then 
' username and password match - this is a valid user
Session("MM_Username") = MM_valUsername
' Here is your new code session
Session("MM_code") = Request.Form("code")

然后，在下一页上，要检索代码，只需输入：

<%=Session("MM_code")%>

我刚发布之前测试了这个，它可以正常工作。：）
