Are you sure you don't have a file included above that script called member.php? If you do, make sure you don't already have session_start already called in that file.

Nope I dont know whats going on ill send ya the code of the script

 

<?php

$usernamea=$_POST['username'];

$title=$usernamea;

?>

<title>

Welcome <?php echo $title; ?>!

</title>

<?php

include_once("includes/config.php");

mysql_select_db($data,$connect) or die ("Cannot Connect to Database Server");

$username=$_POST['username'];

$password=$_POST['password'];

// Connections

$sql="SELECT * FROM users WHERE username='$username' && password='$password'";

$query=mysql_query($sql);

$row=mysql_fetch_assoc($query);

$totalRow=mysql_num_rows($query);

// If username is correct

if ($username = $row['username']) {

// If password is correct

if ($password = $row['password']) {

?>

<?php

session_start();

session_register('user_id');

// store session data

$_SESSION['username'];

//retrieve session data

echo "Welcome". $_SESSION['username'];

?>

 

<?php

echo "Password is Incorrect! <a href='index.php'>Try Again</a>";

}

echo "Wrong Password or the User does not exist! <a href='index.php'>Try Again</a>";

}

mysql_free_result($query);

You Are declaring session_register(); Before your session_register. Try:::

 

<?php
session_start();
$usernamea=$_POST['username'];
$title=$usernamea;
?>
<title>
Welcome <?php echo $title; ?>!
</title>
<?php
require_once("includes/config.php");
mysql_select_db($data,$connect) or die ("Cannot Connect to Database Server");
$username=$_POST['username'];
$password=$_POST['password'];
// Connections
$sql="SELECT * FROM users WHERE username='$username' && password='$password'";
$query=mysql_query($sql);
$row=mysql_fetch_assoc($query);
$totalRow=mysql_num_rows($query);
// If username is correct
if ($username = $row['username']) {
// If password is correct
if ($password = $row['password']) {
?>
<?php
session_register('user_id');
// store session data
$_SESSION['username'];
//retrieve session data
echo "Welcome". $_SESSION['username'];
?>

<?php
} else {
echo "Password is Incorrect! <a href='index.php'>Try Again</a>";
if (session_is_registered('username'){
session_unregister('username')
}
}
} else {
echo "Wrong Password or the User does not exist! <a href='index.php'>Try Again</a>";
if (session_is_registered('username'){
session_unregister('username')
}
}
mysql_free_result($query);
?>

 

Hope this helps Andrew?

Oops sorry error in my code. Try:

 

<?php

$usernamea=$_POST['username'];
$title=$usernamea;
?>
<title>
Welcome <?php echo $title; ?>!
</title>
<?php
require_once("includes/config.php");
mysql_select_db($data,$connect) or die ("Cannot Connect to Database Server");
$username=$_POST['username'];
$password=$_POST['password'];
// Connections
$sql="SELECT * FROM users WHERE username='$username' && password='$password'";
$query=mysql_query($sql);
$row=mysql_fetch_assoc($query);
$totalRow=mysql_num_rows($query);
// If username is correct
if ($username = $row['username']) {
// If password is correct
if ($password = $row['password']) {
?>
<?php
session_register('user_id');
// store session data
$_SESSION['username'];
//retrieve session data
echo "Welcome". $_SESSION['username'];
?>

<?php
} else {
echo "Password is Incorrect! <a href='index.php'>Try Again</a>";
if (session_is_registered('username'){

echo "Wrong Password or the User does not exist! <a href='index.php'>Try Again</a>";
if (session_is_registered('username'){
session_unregister('username');
}
}
mysql_free_result($query);
?>

 

Cuase you get a:

Parse error: syntax error, unexpected '{' in C:\xampp\htdocs\newsite\member.php on line 35

It's because session_start() has to be called at the very top of your script.

[Crew-Portal]

I already made that mod in the scripts just above you. lolz

[pocobueno1388]

Oops, sorry...I didn't see that

[Crew-Portal]

Thats no problem. I was talkin' to the guy on MSN (Andrew I mean) And I belive he got his problem fixed. But I guess we'll wait till tommorrow for a response
