我的login.php

HI I''m trying make a Diary application where people can log in and submit to their daily diary. I have created. I have started to create the login page and once the user is logged in he will be directed to a members page.
What Im having a hard time with is getting the users name to display on the members page. Im not sure how to get the user name. I have been doing the php tutorials. here''s what I have so far and hope some of you guys can point me to the right directions.

my login.php

<?php
include 'conn.php';

if (loggedin()==TRUE)
	header("Location: usersarea.php");

if ($_POST['login'])
{
	//get data
	$username = $_POST['username'];
	$password = $_POST['password'];
	$rememberme = $_POST['rememberme'];
	// $login = $_POST['login'];
	
	
	if ($username&&$password)
	{
	
	$login = mysql_query("SELECT * FROM users WHERE username='$username'");
	while ($row = mysql_fetch_assoc($login))
	{
		$db_password = $row['password'];
		if(md5($password)==$db_password)
		$loginok = TRUE;
		else
		$loginok = FALSE;
		if ($login==TRUE)
		{
			if($rememberme== 0)
			setcookie("username", $username, time()+7200);
			else if($rememberme== 1 )
			$_SESSION['username']=$username;
			
			header("Location: usersarea.php");
			exit();
			
		}
		else
			echo("incorrect username/password.");
		
	}
		
	}
	else{
		echo("Wrong");
	}
}

}



?>

我的数据库

my db

<pre lang="text">
CREATE TABLE `users` (
  `id` int(25) NOT NULL AUTO_INCREMENT,
  `username` varchar(65) NOT NULL DEFAULT '''',
  `password` varchar(32) NOT NULL DEFAULT '''',
  `EmailAddress` varchar(255) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=4 DEFAULT CHARSET=latin1;

推荐答案

_POST ['login']) { //获取数据

_POST['login']) { //get data

用户名=

_POST ['username'];

_POST['username'];
