There is a script that control a part of code in a conditional statement example if login fails redirect in other section of the page like this site dmxzone.com?
In this site when you put a wrong login and password in the right of the page appear a message in the same place:

<b><font color=red>Invalid Username or password! </b></font id=red>
Username:
Password:

Save Password?

Forgot your Password?
Sign up / register

Can we help me to write the script of the conditional statement if login fails changes only the right portion of the page with message (INVALID USERNAME OR PASSWORD) and the other portion of the page like section left and center do not change?

Thanks a lot (sorry for my bad english)

Hi

Are you using the 'Log In User' server behaviour? If you are then set the 'If Login Fails, Go To:' field to the name of your login page and ?err=1, like this:

myLoginPageName.asp?err=1

You can then check for 'err=1' in the quesrystring and display text if it exists, like this:

<%
If Request.QueryString("err"

= "1" Then
Response.Write("Invalid Username or Password"

End If
%>

Thanks Digga

But If the users wants logging in every moment I must set a page for error logging, there is a way where the user when insert username and password in every moment (each section of the site) change only the include file which contains username and password fields like this site?

If you want I send you the code!

Thanks a lot

I'm sorry but I do not understand what you want, I've answered your original question, well I thought I had, maybe you don't understand the answer.

Then again I probably don't understand your question.

Ok, I try to rewrite the question the most clear I can.
When you see this topic at URL

www.dmxzone.com/forum/topic.asp?TOPIC_ID=29474&FORUM_ID=544&CAT_ID=2&Topic_Title=IF+LOGIN+FAILS&Forum_Title=%2A%2A%2A+Macromedia+MX+%2A%2A%2A

you can see both you are logged and not.
In first case if you are logged in the right section of the page appear the USER STATS and active user.

<img src="www.studioarletti.it/2.jpg" border=0>

In the second case if you are not logged appear the form field with username and password.

<img src="www.studioarletti.it/1.jpg" border=0>

Now if you want to login in anytime, only the right section of the page changes, and the URL is the same.
How I can do this?
There is a way to don't set a redirect URL, but only redirect an other section of the page wich contain a LOGIN FAIL or a LOGGED SUCCESSFULLY?

Thanks a lot

Ric

Hi Pulls

Okay I understand I think.

The answer I gave will do want you want but the 'Log In User' server behaviour will need to be changed when a user fails to login correctly, set the 'If Login Fails, Go To:':

<% Request.ServerVariables("HTTP_REFERER"

& "&err=1" %>

instead of:

myLoginPageName.asp?err=1

And use the code below to check and display the error message:

<%
If Request.QueryString("err"

= "1" Then
Response.Write("Invalid Username or Password"

End If
%>

Hi Ric

Sorry my mistake.

You need to insert this code your asp page above the MM_redirectLoginFailed line:

<%
Dim myRedirect, myReferer

myReferer = Request.ServerVariables("HTTP_REFERER"

If (InStr(1, myReferer, "?", 1) = 0 And Request.QueryString <> ""

Hi

I've quickly checked the code and you've put this code at the bottom of the page:

<%
Dim myRedirect, myReferer

myReferer = Request.ServerVariables("HTTP_REFERER"

If (InStr(1, myReferer, "?", 1) = 0 And Request.QueryString <> ""

Then
myRedirect = myReferer & "?err=1"
Else
myRedirect = myReferer & "&err=1"
End If

%>

I advised you to put it before the MM_redirectLoginFailed line....

<BLOCKQUOTE id=quote><font size=1 face="Verdana, Arial, Helvetica" id=quote>quote:<hr height=1 noshade id=quote>You need to insert this code your asp page <b>above the MM_redirectLoginFailed</b> line:

Then
myRedirect = myReferer & "?err=1"
Else
myRedirect = myReferer & "&err=1"
End If

%>

And change the MM_redirectLoginFailed to:

MM_redirectLoginFailed = myRedirect

If you are still having problems, then post your code.
