[RESOLVED] Loging In

[fmsguy06]

I am trying to make a login that allows me to greet who logged in, i.e. saying "Hello [person who logged in]!"

I think I am close, using

authenticate.php

<?php

session_start();

require_once('database.php');

$username = $_POST['username'];
$password = $_POST['password'];

$sql = "SELECT * FROM users WHERE username='".$username."' AND password='".$password."'";
$run = mysql_query($sql);
$row = mysql_fetch_array($run);

if (mysql_num_rows($run) ==1)
	{
		$_SESSION['logged_in'] = true;
		$_SESSION['id'] = $row['id'];
		$_SESSION['name'] = $row['name'];

header("Location: index.php");
}
	else
	{

	header("Location: login.php");
}
?>

and login.php

<?php



?>

<form action="authenticate.php" method="post">
	Username: <input type="text" name="username" /><br />
	Password: <input type="password" name="password" /><br />
	<input type="submit" value="Login" />
</form>

But in index.php, I am trying to show Hello [login]:

<?php

session_start();

if($_SESSION['logged_in'])
	{
?>

<h3>Hello <?= $_SESSION['name'] ?> (<?= $_SESSION['id'] ?>), </h3>
<h3>You are logged in.</h3>
<a href="logout.php">logout</a>

<?php
}
	else
	{
?>

<h3>You are not logged in.</h3>
<a href="login.php">login</a>

<?php

}

?>

It will show: Hello ( )

Are my parenthesis wrong in index.php? I thank you in advance!

The only difference I see is short-open tags versus long-open tags. Change <?= to <?php echo and see if that helps.

That worked! I certainly thank you!

Hmm...thought of something though. How would I clear a user&#700;s session, so as to log them out?

[bpat1434]

[man]session_destroy/man

or reset it like so:

$_SESSION = array();

Or both:

$_SESSION = array();
session_destroy();

Interestingly enough, the php manual has an example on logging someone out on the session_destroy page 😉

Well I certainly thank you, and I plan on befriending my reading on php manuals even more 🙂
