If ...Then...
Let's modify the above two pages:
first.asp:
<html>
<body>
<form action="second.asp" method="post">
User Name: <input type="text" name="user">
Password: <input type="password" name="pass">
<input type="submit" value="Send Query String">
</form>
</body>
</html>
second.asp:
<html>
<body>
<%
u=request("user")
p=request("pass")
if ((u="John") and (p="John123")) then
response.write "Hi" & u & ", your login is valid."
else
response.write "Sorry, invalid login"
end if
%>
</body>
</html>
Open first.asp on web brower, enter some values as user name and password in
the boxes, then submit. You will see, if you entered "John" for the
user name and "John123" for the password, then the output on second.asp
is:
Hi John, your login is valid
Otherwise, you will see the message:
Sorry, invalid login
The basic syntax of "If... then..." is:
if ... then
...
end if
You can use "else" or "elseif .. then" to make more choices:
if ... then
...
elseif ... then
...
else
...
end if
