Why the user always faced the different page when click back button?

[wish]

Dear all,

I would to ask that why the user always faced the different page when user click the back button instead back to page2.php but it go to page5.php..I remember in asp, we use the global.asa to solve this problem because the server will confuse when many user login the system as a member and every members go different pages.

So may i have anyone to guide me?

Hi wish.

Could you show us your code? There are several different ways of doing what I think you are attempting, and each of them can fail in more ways than I can imagine.
It is very hard to debug code you can not see :)

Hi,

I just have asp language code but i dun know is same as php?

This is the code in asp and called it as global.asa

<script language="VBScript" Runat="server">
sub Session_OnStart()
   session("userid")=""
   session("isuser")="false"
end sub
 
sub Session_OnEnd()
   session("userid")=""
   session("isuser")="false"
end sub
</script>
 

with this page, then the user will not faced the problem in asp.But in php, i dun know this code can apply in or not?

Hi.

Please use [code] tags when posting code. It's impossible to read it without them.

That said...
I'm still not understanding the problem. As far as I can tell the ASP code you posted is meant to reset those two session variables when the session starts and when it ends.
But how does that affect where your user is redirected when he presses the back button?
Why would you want to reset those variables when the sessions starts and when it ends?
Couldn't you then just as well use regular global variables?

The code you posted can be easily re-written in PHP. I am not very good with ASP, however, so I don't know if your subroutines get called by some automatic ASP mechanism or manually by your.
In PHP you would have to call them manually.

Hi,

Let say the application is run at the server now and got two people are access the application and one user is browse page2.php and another user browse is page5.php. When the first user in page2.php click back button then the first user cant back the original page but the page is back on the first user pc is the page that browse by the second user.

My problem is solve the confuse in multiuser in application.

Can u give me ur guideline?

[Atli]

Ok, I'm trying to understand what you mean.

What you are saying is...
Your first user is viewing page 2. The second user is viewing page 5.
I'm assuming they both stated at page 1, so when they press the back button, that would be where they should end up?

Now when the first user clicks back, he is sent to the page the second user is currently viewing?

Am I understanding correctly?

Hi Atli,

U r absolutely right. Both users come from the same start page. How the problem can occurs?

[Atli]

Thats weird.

The back button in a browser should not be affected by anything your PHP code is doing, unless you are redirecting it, and certainly not by anything other users are doing. It should go straight back to the last URL it was viewing.
Could the content of that URL be changing?

Unless it is a back button in your web application? That could well send the user somewhere it is not supposed to if there is a error in the code.

How does you application work? Can you give us an example of what the URL looks like on each page? And if you coded the button used to send users back, could you post that code?

Hi,

i just simply write the javascript code and the code in php is

<script>draw_button<"butback","manufaclist.php","" ,"","",""></script>

the problem is no always occur but sometime it will.
