I am trying to display the old varible in the text field and after the user changes the varible in the text field, the new varible will display here

please look at my code:

<html>
<body>
<form action="a.asp" method="post">
Your name: <input type="text" name="fname" size="20" value="<% response.Write(fname) %>" />
<input type="submit" value="Submit" />
</form>
<%
session fname
fname=Request.Form("fname")
If fname<>"" Then
Response.Write("Hello " & fname & "!<br />")
Response.Write("How are you today?")
End If
%>
</body>
</html>

Without doing all the work for you... it looks like when you write the value into the textfield there is nothing there.

This is because the value is empty.

Why is it empty?

your codes back to front...

you need to create the session at the top of the page

code wrote:

<html>
<%session fname
fname=Request.Form("fname")
%>
<head></head>
<body>
<form action="a.asp" method="post">
Your name: <input type="text" name="fname" size="20" value="<% response.Write(fname) %>" />
<input type="submit" value="Submit" />
</form>
<%
If fname<>"" Then
Response.Write("Hello " & fname & "!<br />")
Response.Write("How are you today?")
End If
%>
</body>
</html>

also i think it should be...

code wrote:

<%
if request.form("fname") <> "" then
session("fname")= Request.Form("fname")
end if
%>

for an actual session

what you've done there is just create a string

so the rest of your code would look like as follows:

code wrote:

<%
If fname<>"" Then%>
Hello <%=session("fname")%>!<br />
How are you today?
<%
End If
%>

and like this:

code wrote:

<form action="a.asp" method="post">
Your name: <input type="text" name="fname" size="20" value="<%=server.htmlencode(session("fname"))%>" />
<input type="submit" value="Submit" />
</form>
