[SOLVED] about the query redirection

[ted_chou12]

Below is my script:
[code]
<?php $page = "{$_SERVER['PHP_SELF']}?{$_SERVER['QUERY_STRING']}";//when I try only $_SERVER['PHP_SELF'], the redirection works, but when I try it with query, it only to the page name without the query.
}
break;
case "login":
$username = isset($_POST["username"])?$_POST["username"]:"";
$password = isset($_POST["password"])?$_POST["password"]:"";

if ($username=="" or $password=="" )
{
echo "<h1>Username or password is blank</h1>";
clearsessionscookies();
header("location: $page?returnurl=$returnurl");
}
else
{
if(confirmuser($username,$password))
{
createsessions($username,$password);
if ($returnurl<>"")
header("location: $returnurl");
else
{
header("location: /users/confirm.php");
}
}
else
{
echo "<h1>Invalid Username and/Or password</h1>";
clearsessionscookies();
header("location: $page?returnurl=$returnurl");
}
}
break;
case "logout":
clearsessionscookies();
header("location: index.php");
break;
}
?>[/code]

What do you see if your echo $page?

[ted_chou12]

opps sorry, i think is because i have the confirm.php at the bottom...
yeap when i see echo page, its fine, is this:
header("location: /users/confirm.php");
thats having the problem
but now I changed it to this
header("location: $page");
it doesnt work at all now, it redirects to the index.php after login, no matter whan $page is...
Can you help me with this?
Thanks Ted

What do you see if your echo $page?

[ted_chou12]

what is 'HTTP_REFERER'? i checked the manual, but i dont understand...
The address of the page (if any) which referred the user agent to the current page. This is set by the user agent. Not all user agents will set this, and some provide the ability to modify HTTP_REFERER as a feature. In short, it cannot really be trusted.
does it give me the previous url? if not, what does give me the previous filename of the page? i need the previous page filename eg. "/test.php?id=test" <<< something like this would work.

Can you read?

[ted_chou12]

Nope, it doesnt work, I dont understand, why doesnt this work?
[code]
<?php  $page = "{$_SERVER['PHP_SELF']}?{$_SERVER['QUERY_STRING']}";//Get the page url
echo $page;// echo page
}
break;
case "login":
$username = isset($_POST["username"])?$_POST["username"]:"";
$password = isset($_POST["password"])?$_POST["password"]:"";

if ($username=="" or $password=="" )
{
echo "<h1>Username or password is blank</h1>";
clearsessionscookies();
header("location: $page?returnurl=$returnurl");
}
else
{
if(confirmuser($username,$password))
{
createsessions($username,$password);
if ($returnurl<>"")
header("location: $returnurl");
else
{
header("location: $page");//redirects to page after login
}
}
else
{
echo "<h1>Invalid Username and/Or password</h1>";
clearsessionscookies();
header("location: $page?returnurl=$returnurl");
}
}
break;
case "logout":
clearsessionscookies();
header("location: index.php");
break;
}
?>
[/code]
when i try echo $page it shows me this:
/users/confirm.php?confirm=gbedit
but after login, it does redirect to this but it redirects to the index.php of that folder, i dont understand why..

[trq]

The Location header requires a fully qualified url to be reliable. Meening....

[code]
http://yoursite.com/users/confirm.php?confirm=gbedit
[/code]

[ted_chou12]

nope doesnt work, because the user folder will always be included, so i did this:
http://mysite.com$page
but it doesnt work, it just redirects me to http://mysite.com and no $page, but when I echo, the $page comes out right.

[trq]

Your not defining $page within the same case. Also... you cannot echo ANYTHING to the screen prior to a call to header().

[ted_chou12]

okay, is no problem now, i think is because I am having some paging problems, because confirm.php includes this page i posted (login.php) so the variables cannot be passed while the login.php is checking the login, because the url is already so messed up so ive set a session to it:
$_SESSION['page'] = $page;
in order to pass the variable to the next page,
header("location:  {$_SESSION['page']}");
so now the header redirection works fine :)
so happy now i got it right, Thanks thorpe
