Sessions question

badgoat

Hello!

I have set up sessions on my script. A user must enter a username and password which checks a SQL table. Upon successful entry, the user is allowed in. All works! The problem: I cannot figure out how to echo the user_name in a header after the user has logged in.

Welcome, '.$user_name.'

Doesn't echo anything. What am I overlooking?

is the username coming from a form using the POST method? if so then:

echo 'Welcome ' . $_POST['user_name'];

Um.... echo()

echo 'Welcome '.$user_name;

Or even

echo 'Welcome '.$_SESSION['user_name'];

I am not quite THAT noobish :p
POST and SESSION didn't work either.. Here's a portion of the script which takes two variables from the preceding form:

<?
	include ("config.php");

   $user_name=$_POST['user_name'];
   $user_password=$_POST['user_password'];

$query="SELECT * FROM users WHERE user_name='$user_name' and user_password='$user_password'";
$result=mssql_query($query);
$count=mssql_num_rows($result);
if($count==1){
session_register("user_name");
header("location:../index.php");}
else {
echo '<font color="red"><b>Wrong Username or Password</b></font>';}
?>

From the Manual

Caution:
If you want your script to work regardless of register_globals, you need to instead use the $SESSION array as $SESSION entries are automatically registered. If your script uses session_register(), it will not work in environments where the PHP directive register_globals is disabled.

So replace this

session_register("user_name");

with this

$_SESSION['user_name'] = $_POST['user_name'];

then you can use

echo 'Welcome '.$_SESSION['user_name'];
