if ($HTTP_GET_VARS["step"] == "detail")
{
echo("
<h1>here's a detail for user</h1>
<a href='?who=user'>home</a><hr />
new item detail<hr />
");
}

}
}


?>


why is it opening up the next information on the same page? and when i click on the user view detail, it goes back a step.
does anyone understand the code, or me?!

thanks for your time everyone.

Okay, here's the logical blocks of your code:

if ($_GET["who"] == "admin")
{
	//output default admin page

	if ($_GET["step"]  == "list")
	{
		//output admin list stuff
	}
}
else 
{
	//output default user page
	if ($_GET["step"]  == "list")
	{
		//output user list stuff
	
		if ($_GET["step"]  == "detail")
		{
			//output user detail stuff
		}
	}
}

If who is "admin", the script will always output the default admin page. If the step is "list", the script additionally outputs the list.

If the who is "user", the script will always output the default page. If step is "list", it will also output the list. However, the detail section will never be run, as that section of code is nested inside the if-block that outputs the list. Step cannot be both "list" and "detail".

What is it you want this thing to do?

Also there is no else to catch other events.

eg.

if ($_GET["who"] == "admin")
{[b]
    //output default admin page
    if (!isset($_GET["step"]))
    {
        $_GET["step"] = "list";
    }
[/b]
    if ($_GET["step"]  == "list")
    {
        //output admin list stuff
    }
    else
    {
         echo "you bad boy!";
    }
}
...

wait, this one is better:

    if ($_GET["step"]  == "list" || !isset($_GET["step"]))
    {
        //output admin list stuff
    }

I suspect that our questioner hasn't got the intended logic straight in his own head.

hmm, maybe so..
My eyes burn, my eyes burn.. (after reading the red fontcolor on blue bgcolor)

I think that some colors should be banned from this forum, or maybe just all colors.

Some exceptions though, as if they are inside the code-tags, they might be usefull, if not abusefull.
