ASP Object Example - Passing Values between Pages

This section provides a tutorial example on how to pass values from one page to another. This example is a very simple registration application with two ASP pages.

There are many ways to pass values from one pages to the next pages:

In the following example, I have two ASP pages working together as a registration process. Here is the fist ASP page, reg_form.asp:

<script language="vbscript" runat="server">
'  reg_form.asp
'- Copyright (c) 1998 All Rights Reserved.
'  This ASP page presents a registration form, and collects the input
'  data.
  submit = request.QueryString.Item("submit")
  if submit = "Submit" then
    ' Collecting the input data
    session.Contents("url") = request.QueryString("url")
    session("email") = request.QueryString("email")
    application("first_name") = request.QueryString("first_name")
    response.Redirect("reg_done.asp?last_name=" & _
    ' Presenting the registration form 
    response.write("<b>Registration Form</b>:<br>")
    response.write("<form action=reg_form.asp method=get>")
    response.write("First Name:")
    response.write("<input type=text size=16 name=first_name><br>")
    response.write("Last Name:")
    response.write("<input type=text size=16 name=last_name><br>")
    response.write("<input type=text size=32 name=email><br>")
    response.write("<input type=text size=32 name=url><br>")
    response.write("<input type=submit name=submit value=Submit><br>")
    response.write("Your session ID is " & session.SessionID & "<br>")
  end if

Here is the second ASP page, reg_done.asp:

<script language="vbscript" runat="server">
'  reg_done.asp
'- Copyright (c) 1998 All Rights Reserved.
'  This ASP page confirms a registration.
   ' Save the data here
   response.write("<b>Thank you registering with us</b>:<br/>")
   response.write("First Name:")
   response.write(application("first_name") & "<br/>" & vbNewLine)
   response.write("Last Name:")
   response.write(request.QueryString("last_name") & "<br/>" _
      & vbNewLine)
   response.write(session("email") & "<br/>" & vbNewLine)
   response.write(session("url") & "<br/>" & vbNewLine)
   response.write("Your session ID is " & session.SessionID & "<br/>")

Request reg_form.asp with IE, and fill in the form with:

First Name: Bill
Last Name: Smith

Then click the Submit button, you will get the output of reg_done.asp:

Thank you registering with us:
First Name:Bill
Last Name:Smith
Your session ID is 42285894
