username and password!!

[ilikephp]

Hello!!

 

In my website, I need to create a php form that contains username and passwords, so the users can sign up automatically and they get their own username and password,

 

How can I do it plz? and how can I make a link to the database so it will check if the username is taken or not and it can display all the username and passwords.

 

Thanks in advance!!

I created a flat-file db login system if you'd like to modify it for your needs.

 

INDEX.PHP

<?PHP

include("main.php");

$login->secure();

echo "You are in the member zone!<br /><a href=\"logout.php\">Logout!</a>";

?>

 

MAIN.PHP

<?PHP

session_start();

include("loginclass.php");
$login = new login();

?>

 

LOGINCLASS.PHP

<?PHP

class login {		

public function checklogin() {
	$detailsarray = $this->getdetails();
	if ($_POST['username'] == $detailsarray[0] && md5($_POST['password']) == $detailsarray[1]) {$this->grant_session(); return true;}	
}

public function is_submit() {
	if ($_POST['submit']) return true;
}

public function is_session() {
	if ($_SESSION['login']) return true;
} 

public function getdetails() {
	$details = file_get_contents("details.php");
	$both = explode(":", $details);
	return $both;
}

public function grant_session() {
	$_SESSION['login'] = true;
}	

public function logout() {
	session_destroy();
}

public function redirect() {
	header("Location: {$_SESSION['FROM']}");
}

public function saveref() {
	$_SESSION['FROM'] = $_SERVER['PHP_SELF'];
}

public function showform() {
	print '
	<form action="'.$_SESSION['FROM'].'" method="post">
	<input type="text" name="username"><br />
	<input type="password" name="password"><br />
	<input type="submit" name="submit">
	</form>';
}

public function secure() {
	$this->saveref();
	if (!$this->is_session()) {
		if ($this->is_submit()) {
			if ($this->checklogin()) $this->redirect(); else echo "Wrong username/password!";
		} else $this->showform(); die;
	}			
}


}

?>

 

LOGOUT.PHP

<?PHP

include("main.php");

$login->logout();
$login->redirect();

?>

 

DETAILS.PHP

admin:21232f297a57a5a743894a0e4a801fc3 //admin:admin

 

It will be pretty easy for this point.

Thanks for helping me!!

 

I created all the scripts but in the details.php I left it empty.

 

So when I put the username and password and I got: Wrong username/password!

 

So till now I think everything is OK.

 

So the second step, how can I create a username and password?

 

Thanks!!
