where would u go for a simple login form tutorial

personally I wouldn't mind going to cuba for one .. but I'm not sure they'd have one there


How simple do you want ?

Does it pull from a database or it it simply to hide some in page info ...

Could you use .htaccess for the pages which might be simpler

Hi,

In my opinion, you should go right here for a login form tutorial!

<?php

// Use this at the top of every page you want to retain the user's login state
session_start();

// This function returns true (and stores some info in the session) if we have a valid user and returns false if not.
function validUser($username,$password)
{

// Connect to your database (replace hostname, username, password, dbname with your own database details)
mysql_connect('hostname','username','password') or die ('Can\'t connect to database server');
mysql_select_db('dbname') or die ('Can\'t use database');

// Escape nasty characters to preven sql injection (never trust user input)
$username = mysql_real_escape_string($username);
$password = mysql_real_escape_string($password);

// You will have had to set up a user table in the database
// Change the table, Username and Password to suit your database structure
$query = "SELECT COUNT(*) AS count FROM table WHERE Username='" . $username . "' AND Password='" . $password . "'";
$result = mysql_query($query);

// If we have found one row, the user is a valid user
if(mysql_num_rows($result) == 1){

// Store some data in the session for use later if you want
$_SESSION['loggedIn'] = 1;
$_SESSION['username'] = $username;

return TRUE;

// If there are zero or more than 1 rows the user is not a valid user.
// You will have to prevent the same user creating multiple accounts with the same details in your registration form code
} else {

return FALSE;

}

}

// If the login form was submitted...
if(isset($_POST['login'])){

// If we don't have a valid user, display an error message
if(!validUser($_POST['username'],$_POST['password'])){

echo '<p>You did not provide valid login details</p>';

// If we do have a valid user, display a welcome message
} else {

echo '<p>Thanks, you are now looged in!</p>';

}

}

?>

<form name="login" method="post" action="">
<p><label>Username:</label><input type="text" name="username" id="username" /></p>
<p><label>Password:</label><input type="text" name="password" id="password" /></p>
<p><input type="hidden" name="login" value="1" /><input type="submit" value="Login" /></p>
</form>

Copy all that code above into your code editor so you can read it easier with syntax highlighting, I still haven't figured out how to display php code with syntax highlighting in this forum!

Make sure you use session_start(); at the top of all pages where you want to check for logged in users with a bit of extra code...

<?php

session_start();

if($_SESSION['loggedIn'] != 1){

echo 'You must be logged in to view this page';
exit();

}

?>
