Adding to database?

[gk20]

I have a php file where I allow users that are logged in to add to the database.I am using session_start() and session_checker() to see of the user is logged in before allowing them access to this page. That works fine. But when I add their info to the database I also want to add their username with it, to associate this informtion with them without asking them for it again??? Is there anyway I could use their loginname from login.php in the placead.php file?
Heres login.php

$login = $_POST['login'];
$pass = $_POST['pass'];
...
...
session_register('login');
$_SESSION['loginname'] = $login;

session_register('pass');
$_SESSION['password'] = $pass;

heres placead.php

$itemname = $_POST['itemname'];
$description = $_POST['description'];
$category = $_POST['category'];
$cost = $_POST['cost'];
$location = $_POST['location'];

when I'm storing these values can I how can I store the username of that person with the information??
Please help, I've tried looking in to sessions, but I can't seem to understand it!!!

You start placead.php with

Session_start()

Then you can call up the variable $_SESSION['loginname'] anytime after that and it will give you that value.

Sorry, I have tried this. In my placead.php file i have this at top

<?php include 'db.inc.php'; ?>
<?php
session_start();
session_checker();
?>
.......
.......
session_register('loginname');
$itemowner = $_SESSION['loginname'];

so when I'm adding to database: insert into item set ..... itemowner = '$itemowner'
but it still leaves itemowner field blank!

would it have anything to do with db.inc.php file??
......
function session_checker()
{
if(!session_is_registered('loginname'))
{
if(!session_is_registered('loginpass'))
{
echo "<p>You must be logged in to view this page</p>";
echo "<b><br><br/><a href=login.php?loginuser=1>Login</a></b>";
exit();
}
}
}

Its really bugging me, it should be easier!!!

Try this way ok.


If session_start () is not at the very top of a page with no text above it should work, i say agin no text above it.

Also chage this ok
include ('db.inc.php');

To this save page to database.php
include ('database.php');




good luck.


[code]
<?php session_start();


session_checker();

// this needs to be saved as database.php not what you had.
include ('database.php');


//session_register('loginname');
$itemowner = $_SESSION['loginname'];

//so when I'm adding to database: insert into item set .....
$itemowner = '$itemowner'
//but it still leaves itemowner field blank!

//would it have anything to do with db.inc.php file??

function session_checker()
{
if(!session_is_registered('loginname'))
{
if(!session_is_registered('loginpass'))
{
echo "<p>You must be logged in to view this page</p>";
echo "<b><br><br/><a href=login.php?loginuser=1>Login</a></b>";
exit();
}
}
}
?>
