Lidt Problemer Med Sessions. Argh .

Fjern din session_start hvis det er en fil som includeres.

<?
include("sql.php");

$hej = mysql_query("SELECT * FROM brugere WHERE id='$_SESSION[id]'");
$vis = mysql_fetch_array($hej);

echo " $vis[id]";
?>

sql.php er kun den som forbinder til min db .. der er kun 4 linier i den ..

sql.php :

<?
@mysql_connect ("localhost" , "root" , "");
@mysql_select_db ("mindb");
?>

Ja, men prøv fjern session_start :-)

nu er der intet output.. nu er skærmen helt blank ..

<?
include("sql.php");

$hej = mysql_query("SELECT * FROM brugere WHERE id='$_SESSION[id]'");
$vis = mysql_fetch_array($hej);

echo " $vis[id]";
echo " $_SESSION[id]";
?>

Den fil "retprofil.php" bliver den included fra en index.php fil?

Hvis ja - så fjern session_start() og include("sql.php"); og sæt det op i toppen af index.php filen fremover.

man sendes til retprofil.php via et hyperlink ..

<li><a href=\"retprofil.php\" title=\"Ret Din Profil\">Ret Profil</a></li>

Det skal lige siges at jeg tester via WAMP5 .. men det burde da ikk ha nogen ting at sige ?

Hmm - er du sikker på session_start(); ikke er sat i dokumentet et andet sted?
Ellers skal du huske den skal være øverst i dokumentet.

Desuden hvis det ikke virker, så skal du ind og rette i din php.ini fil ( tror jeg ) det har jeg ikke forstand på!

Det her er hvad jeg kunne finde i min php.ini angående sessions .. skal noget af det rettes ?

; 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
;
; The file storage module creates files using mode 600 by default.
; You can change that by using
;
;    session.save_path = "N;MODE;/path"
;
; where MODE is the octal representation of the mode. Note that this
; does not overwrite the process's umask.
session.save_path = "c:/wamp/tmp"

; 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_divisor,
; e.g. 1/100 means there is a 1% chance that the GC process starts
; on each request.

session.gc_probability = 1
session.gc_divisor    = 100

; After this number of seconds, stored data will be seen as 'garbage' and
; cleaned up by the garbage collection process.
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

; Select a hash function
; 0: MD5  (128 bits)
; 1: SHA-1 (160 bits)
session.hash_function = 0

; Define how many bits are stored in each character when converting
; the binary hash data to something readable.
;
; 4 bits: 0-9, a-f
; 5 bits: 0-9, a-v
; 6 bits: 0-9, a-z, A-Z, "-", ","
session.hash_bits_per_character = 4

; 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="

intet brugbart svar ... :(
