Hello Devey,
$v_dec["page_no"] = $page_no; Which means that $v_dec will always equal nothing, because at the point at which the file is included, $page_no hasn't been set to anything at all. You mean this will unset $v_dec["page_no"]?This explains why at reload of index.php happens what happend. But how to solve it? I _have_ to store some variables anywhere. The session management at this point is rudimentary. I wrote it that way, that it works for now, i.e. building the query pages. This is of course not the final session management. At login I just write the session_id() into the table without checking if the user already owns a session. I left it to the end of work. So maybe it is not a problem of login_status()? function check_user($check_name, $check_passw) { $connect = @OCILogon("", "", ""); if(!$connect)
{
$err_oci = OCIError();
echo "(2) No connection - OCIError(): ".$err_oci["message"];
echo "<p>";
}
else
{
$sql_check = "SELECT count(*) AS count FROM user_web
WHERE user_name = '".$check_name."' AND user_pass = '".$check_passw."'";
$stmt = OCIParse($connect, $sql_check);
OCIExecute($stmt);
while(OCIFetch($stmt))
{
$res_check = (int) OCIResult($stmt, "COUNT");
}
if(!$res_check == 1)
{
OCIFreeStatement($stmt);
OCILogOff($connect);
return(false);
}
else
{
$sql_check = "SELECT user_pid FROM user_web
WHERE user_name = '".$check_name."' AND user_pass = '".$check_passw."'";
$stmt = OCIParse($connect, $sql_check);
OCIExecute($stmt);
while(OCIFetch($stmt))
{
$user_pid = (int) OCIResult($stmt, "USER_PID");
}
OCIFreeStatement($stmt);
OCILogOff($connect);
return($user_pid);
}
}
}
function login($user_pid, $session_id)
{
$connect = @OCILogon("", "", "");
if(!$connect)
{
$err_oci = OCIError();
echo "(2) No connection - OCIError(): ".$err_oci["message"];
echo "<p>";
}
else
{
$sql_login = "UPDATE user_web SET user_session = '".$session_id."'
WHERE user_pid = '".$user_pid."'";
$stmt = OCIParse($connect, $sql_login);
OCIExecute($stmt);
}
OCIFreeStatement($stmt);
OCILogOff($connect);
}
function login_status($session_id)
{
$connect = @OCILogon("", "", "");
if(!$connect)
{
$err_oci = OCIError();
echo "(2) No connection - OCIError(): ".$err_oci["message"];
echo "<p>";
}
else
{
$sql_session_id = "SELECT count(user_session) FROM user_web
WHERE user_session = '".$session_id."'";
$stmt = OCIParse($connect, $sql_session_id);
OCIExecute($stmt);
while(OCIFetch($stmt))
{
$res_status = OCIResult($stmt, "COUNT(USER_SESSION)");
}
if(!$res_status == 1)
{
return(false);
}
else
{
return($res_status);
}
}
OCIFreeStatement($stmt);
OCILogOff($connect);
}
Now I changed $page_no to $v_dec["page_no"] with the same result.
If through submitting a form index.php is reloaded, but the value in $v_dec["page_no"] get lost.
#manage.php
<?php
$session_id = session_id();
include('variables.php');
include('functions.php');
if(!isset($v_dec["page_no"]))
{
$v_dec["page_no"] = "login";
}
if(!(login_status($session_id)) == 1)
{
$v_dec["page_no"] = "login";
}
/* User logged in? */
if(!($v_dec["page_no"] == "login"))
{
include('head.php');
}
else
{
if(isset($_POST['login']))
{
if(!($_POST['user'] == "") && !($_POST['passw'] ==""))
{
$user_pid = check_user($_POST['user'], $_POST['passw']);
if(($user_pid != false) && (login_status($user_pid) == false))
{
login($user_pid, $session_id);
$res_login = 1;
$v_dec["page_no"] = "start_auswahl";
}
else
{
$res_login = 0;
$res_login_text = "Login incorrect.";
}
}
else
{
$res_login = 0;
$res_login_text = "Insert Login AND Passwort.";
}
}
else
{
$res_login = 0;
}
if($res_login == 0)
{
include('b_login.php');
}
}
