I have been trying to update & fix the errors.
With the new code (That I will post at the end), I'm only getting one
error and that is that it can't start the session because that it has
been started.
CODE:
<?php
session_start();
if(isset($_POST['username']) && isset($_POST['passwd']))
{
$username = $_POST['username'];
$passwd = $_POST['passwd'];
/* Connecting to database */
$db = pg_connect ("
dbname=auth
user=auth
hostaddr=127.0.01
");
$query = "SELECT * FROM auth_user
WHERE name='$username'
AND
password='$passwd'";
/* Running query */
$result = pg_query($db,$query);
//$rows = pg_num_rows($result);
//$rows->pg_num_rows($result);
if($rows = pg_num_rows($result) > 0)
{
$_SESSION['valid_user'] = $name;
}
else
{
echo 'Failed';
}
}
?>

if(isset($_SESSION['valid_user']))
{
echo 'You are logged in as: '.$_SESSION['valid_user'].'<br>';
}
else
{
if(isset($username))
{
echo 'Could not log you in';
}
else
{
echo 'You are not login in.<br>';
}
echo '<form method="post" action="login.php">';
echo 'User Name:';
echo '<input type="text" name="username">';
echo 'Password:';
echo '<input type="text" name="passwd">';
echo '<input type="submit" value="Log in">';
echo '</font>';
}
?>
</td>
</tr>
</table>
</body>
</html>
