Passing Values between Pages

This section provides a tutorial example on how to pass values from one ASP page to another using the 'session' object.

There are 3 ways to pass values from one page to the next page:

In the following example, I have two ASP pages working together as a registration process and using "session" object to pass data across pages. Here is the fist ASP page, reg_form.asp:

<script language="vbscript" runat="server">
'  reg_form.asp
'  Copyright (c) 2002 by Dr. Herong Yang
'  This ASP page presents a registration form, and collects the input
'  data.
'
   response.write("<html><body>")
   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=" & _
         request.QueryString("last_name"))
   else
      ' 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("Email:")
      response.write("<input type=text size=32 name=email><br/>")
      response.write("URL:")
      response.write("<input type=text size=32 name=url><br/>")
      response.write("<input type=submit name=submit value=Submit></br>")
      response.write("</form>")
      response.write("Your session ID is " & session.SessionID & "<br/>")
   end if
   response.write("</body></html>")
</script>

Here is the second ASP page, reg_done.asp:

<script language="vbscript" runat="server">
'  reg_done.asp
'  Copyright (c) 2002 by Dr. Herong Yang
'  This ASP page confirms a registration.
'
   response.write("<html><body>")
   ' Save the data here
   response.write("<b>Thank you registrating 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("Email:")
   response.write(session("email") & "<br/>" & vbNewLine)
   response.write("URL:")
   response.write(session("url") & "<br/>" & vbNewLine)
   response.write("Your session ID is " & session.SessionID & "<br/>")
   response.write("</body></html>")
</script>

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

First Name: Bill
Last Name: Smith
Email: bill@smith.com
URL: www.smith.com

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

Thank you registrating with us:
First Name:Bill
Last Name:Smith
Email:bill@smith.com
URL:www.smith.com
Your session ID is 42285894
