Ole Chat problemer

Sjovt, prøver jeg at logge ind igen, så er mit nick optaget... Den er altså forbindelse til databasen, -kan jeg lige konkludere...

Min config:

<?
# ------------------------------------------
#  Server variables
$db_server = "localhost";
$db_user = "(min user)";
$db_pass = "(mit pass)";
$db_db = "chat";

# ------------------------------------------
#  The longest time messages are kept in DB
$maxAge = 60*10; // seconds

# ------------------------------------------
#  Variables used for rendering of messages
$maxNumMsgs = 50;  // Max numbers of lines showed
$hiCol = "#ffffff"; // Highlight row-color
$loCol = "#ededed"; // Lolight row-color

# ==========================================
#  Functionality used globaly (don't alter)
$connection = mysql_connect($db_server, $db_user, $db_pass) or die (mysql_error());
$do_connect = mysql_select_db($db_db, $connection) or die (mysql_error());

if ( !empty($_SESSION) ) {
    extract($_SESSION);
} else if ( !empty($HTTP_SESSION_VARS) ) {
    extract($HTTP_SESSION_VARS);
}

if ( !empty($_GET) ) {
    extract($_GET);
} else if ( !empty($HTTP_GET_VARS) ) {
    extract($HTTP_GET_VARS);
}

if ( !empty($_POST) ) {
    extract($_POST);
} else if ( !empty($HTTP_POST_VARS) ) {
    extract($HTTP_POST_VARS);
}
?>

min login.php:

<?
include ( "config.php" );
if ( isset($user) && $user<>"" && strlen($user)<=15 ) {
    $oldStamp = time() - $maxAge;
    $sql = "delete from messages where stamp<$oldStamp";
    mysql_query( $sql );
    $user = addslashes( $user );
    $sql = "insert into users set user='$user'";
    $res = mysql_query( $sql );
    if ( mysql_affected_rows()>0 ) {
        $msg = "<b>Ny bruger logget på</b>";
        $stamp = time();
        $sql = "insert into messages ( user, msg, stamp ) values ( '$user', '$msg', '$stamp' )";
        mysql_query( $sql );
        session_start();
        session_register( "user_name" );
        $user_name = $user;
        Header ( "Location: index.php" );
    } else {
        $err_msg = "<div style=\"color:#ff0000;font-weight:bold;text-align:center;\">Dette nick er allerede optaget</div>";

Den hedder alså OleBole:O)

hehe, ja.. tror desværre bare ikke det løser problemet :)

I er en hel masser som her logget på kan jeg se... Det virker da heller ikke for jer vel?

hvilken php-version bruger du??
hvilken database??
og har du slået sessions til i config.inc.php -filen?? Altså så du kan bruge disse i dine php-scripts? (evt. en anden side hvor du bruger sessions?!?)

selvfølgelig i din php.ini fil.. ;)

Apache 2.0.45
MySQL 4.0.12
PHP 4.3.1

Hvad hedder indstillingen i config.inc.php?

ja, altså den cirka under /windows/

[Session]
; Handler used to store/retrieve data.
session.save_handler = files

; Argument passed to save_handler.  In the case of files, this is the path
; where data files are stored. Note: Windows users have to change this
; variable in order to use PHP's session functions.
; As of PHP 4.0.1, you can define the path as:
;    session.save_path = "N;/path"
; where N is an integer.  Instead of storing all the session files in
; /path, what this will do is use subdirectories N-levels deep, and
; store the session data in those directories.  This is useful if you
; or your OS have problems with lots of files in one directory, and is
; a more efficient layout for servers that handle lots of sessions.
; NOTE 1: PHP will not create this directory structure automatically.
;        You can use the script in the ext/session dir for that purpose.
; NOTE 2: See the section on garbage collection below if you choose to
;        use subdirectories for session storage
session.save_path = C:\Program Files\Webserver\php\sessiondata    ; argument passed to save_handler

; Whether to use cookies.
session.use_cookies = 1

; This option enables administrators to make their users invulnerable to
; attacks which involve passing session ids in URLs; defaults to 0.
; session.use_only_cookies = 1

; Name of the session (used as cookie name).
session.name = PHPSESSID

; Initialize session on request startup.
session.auto_start = 0

; Lifetime in seconds of cookie or, if 0, until browser is restarted.
session.cookie_lifetime = 0

; The path for which the cookie is valid.
session.cookie_path = /

; The domain for which the cookie is valid.
session.cookie_domain =

; Handler used to serialize data.  php is the standard serializer of PHP.
session.serialize_handler = php

; Define the probability that the 'garbage collection' process is started
; on every session initialization.
; The probability is calculated by using gc_probability/gc_dividend,
; e.g. 1/100 means 1%.

session.gc_probability = 1
session.gc_dividend    = 100

; After this number of seconds, stored data will be seen as 'garbage' and
; cleaned up by the garbage collection process.
; WARNING: Your filesystem must store access times.  Windows FAT does
;          not.  So, see session_set_save_handler() and write your own
;          session handler with a different mechanism for cleaning up sessions.
session.gc_maxlifetime = 1440

; NOTE: If you are using the subdirectory option for storing session files
;      (see session.save_path above), then garbage collection does *not*
;      happen automatically.  You will need to do your own garbage
;      collection through a shell script, cron entry, or some other method.
;      For example, the following script would is the equivalent of
;      setting session.gc_maxlifetime to 1440 (1440 seconds = 24 minutes):
;          cd /path/to/sessions; find -cmin +24 | xargs rm

; PHP 4.2 and less have an undocumented feature/bug that allows you to
; to initialize a session variable in the global scope, albeit register_globals
; is disabled.  PHP 4.3 and later will warn you, if this feature is used.
; You can disable the feature and the warning seperately. At this time,
; the warning is only displayed, if bug_compat_42 is enabled.

session.bug_compat_42 = 1
session.bug_compat_warn = 1

; Check HTTP Referer to invalidate externally stored URLs containing ids.
; HTTP_REFERER has to contain this substring for the session to be
; considered as valid.
session.referer_check =

; How many bytes to read from the file.
session.entropy_length = 0

; Specified here to create the session id.
session.entropy_file =

;session.entropy_length = 16

;session.entropy_file = /dev/urandom

; Set to {nocache,private,public,} to determine HTTP caching aspects
; or leave this empty to avoid sending anti-caching headers.
session.cache_limiter = nocache

; Document expires after n minutes.
session.cache_expire = 180

; trans sid support is disabled by default.
; Use of trans sid may risk your users security.
; Use this option with caution.
; - User may send URL contains active session ID
;  to other person via. email/irc/etc.
; - URL that contains active session ID may be stored
;  in publically accessible computer.
; - User may access your site with the same session ID
;  always using URL stored in browser's history or bookmarks.
session.use_trans_sid = 0

; The URL rewriter will look for URLs in a defined set of HTML tags.
; form/fieldset are special; if you include them here, the rewriter will
; add a hidden <input> field with the info which is otherwise appended
; to URLs.  If you want XHTML conformity, remove the form entry.
; Note that all valid entries require a "=", even if no value follows.
url_rewriter.tags = "a=href,area=href,frame=src,input=src,form=,fieldset="

lukker...
