Hvad er der lige galt her

Linie 22 er de 2 øverste linier

Det ser ellers ok ud syntes jeg, læg et par linier mere evt. fra 'if'

Du mangler vel at starte din {

Fejlen ligger i koden der ligger lige før det du har vist her

<?php
include("common.php");

if(!($link_id = mysql_connect($Host, $User, $Pass))) die(mysql_erorr());
mysql_select_db($DB);

/*This is were the actual log in takes place.  We tell mysql to select the ID where the Name is exactly like the Name from the Form
where is Password is exactly like the encryption values of the password from the form.*/
$sql = "SELECT ID FROM " . $Table . " WHERE Name='" . addslashes($_POST['Name']) . "' AND Password='" . md5($_POST['Password']) . "' LIMIT 1";
if(!($result = mysql_query($sql))) die(mysql_error());

/*This is were we check the result.  We check to see how many rows were in the result of the query. If there is 1 one row in the result, that means
there is one username with the right information, so that would mean they are logged in.*/
if(mysql_num_rows($result) == 1) {
    /*Here we set a cookie that tells if the user has logged in and set it to last for a day.  The cookie is used on the members page to check
    If they cookie is there they can see the page, if not they can't.*/
 
    setcookie("LoggedIn, TRUE, time()+(3600 * 24));


    /*You could also do the header() here just like I explained before.*/
    echo "Continue to the <a href=members.php>Members</a> page.";
} else {
    echo "Login failure";
}
?>

hvad er linje 21?

en forklaring

prøv poste hele den kode som du får fejl i.

det er den du ser

Efter registreing af et brugernavn samt password bliver man sendt videre til logindelen derefter skulle man så gå til den beskyttede side, men der kommer altså fejl i login.php linie 22 og det er den du ser her.

der må vel også være en if() før den kode du har postet

her er fejlen

Parse error: parse error in /usr/www/borbjerg-sk_dk/public_html/login.php on line 22

setcookie("LoggedIn, TRUE, time()+(3600 * 24));

setcookie her en dobbelt-quote, skal der ikke være 2 ?

Fra php documentation:
--------------------------------
Example 307. setcookie() send examples
copy to clipboard
setcookie ("TestCookie", $value);
setcookie ("TestCookie", $value,time()+3600);  /* expire in 1 hour */
setcookie ("TestCookie", $value,time()+3600, "/~rasmus/", ".utoronto.ca", 1);

--------------------------------

sådan skal den vist være:
setcookie("LoggedIn", TRUE, time()+(3600 * 24));

Først registreringen. Login.php har du set

<?php
/* Include the DB connection Parameters */
include("common.php");

/*Connect to the DB using the info in common.php*/
if(!($link_id = mysql_connect($Host, $User, $Pass))) die(mysql_erorr());
mysql_select_db($DB);

/*Here is where the actual work is done. We add slashes to the username
to prevent errors in the query.  Then we encrypt the password.  This password is NEVER decryptable.  Never,
so users can have a sense of security.  We insert, and then we say they are registered.  The Period as joins the strings
togther, so we can join the returns of fucntions to that string without creating a new variable foreach one.*/
$sql = "INSERT INTO " . $Table . " VALUES('', '" . addslashes($_POST['Name']) . "', '" . md5($_POST['Password']) . "')";
if(!($result = mysql_query($sql))) {
    die(mysql_error());
} else {
    /*You can redirect them instead of just giving them a link, to do this:
    you would replace the code below with header("location: login.html");
    Be warned, you can't send headers after text is outputted, so if you wanted
    to have the message, and have them be forwareded, you would have to put the function
    ob_start() at the very first line of this file, and call ob_end_flush() at the very end.*/
    echo "Your user account has been created!<br>";
    echo "<a href=login.html>Continues</a> to the login page";
}

?>

Virkede mit svar ikke ?

Fejlen kommer ikke i cookielinien, men i 24, hvor linket er

Det hjalp en smule, men nu kommer denne her

Warning: Cannot add header information - headers already sent by (output started at /usr/www/borbjerg-sk_dk/public_html/common.php:13) in /usr/www/borbjerg-sk_dk/public_html/login.php on line 18
Continue to the Members page.

Nogle gange melder php fejl i linien efter fejlen, og JO der ER fejl i setcookie funktionen.

Ja, men det virker nu bortset fra at jeg får denne "warning"

Ja det er fordi at du udskriver html før din session_register(); det må man ikke.

Jeg kan ikke se din session_register(); men den må næsten ligge i common.php
