Hi guys, can someone help me out please; I try to put the login page (login.php), index page and register page all on one page. I wonder if that possible or good idea?
Here are my code:
index.php

<title>Untitled Document</title>
</head>
<body>
<!--form action="<?php echo $_SERVER['PHP_SELF'];?>" method="post"-->
<form action="login.php" method="post">
Username: <input type="text" name="username" /><br />
Password: <input type="password" name="password" /><br />
<input type="submit" value="Log in" />
</form> <p>
<a href="register.php">Register?</a>
</body>
</html>
login.php
<?php
$username = (isset($_POST['username'])) ? $_POST['username'] : '';
$password = (isset($_POST['password'])) ? $_POST['password'] : '';
if($username && $password) {
$connect = mysql_connect("localhost", "root", "") or die ("Couldn't connect!");
mysql_select_db("friendsdb") or die ("Couldn't find the DB");
$query = mysql_query ("SELECT * FROM `user` WHERE username = '$username'");
$numrows = mysql_num_rows($query);
if ($numrows != 0){
while ($row = mysql_fetch_array($query)) {
$dbusername = $row['username'];
$dbpassword = $row['password'];
}
//Check to see if they are match!
if ($username == $dbusername && md5($password) == $dbpassword) {
echo "You are in! <a href = 'member.php'> Click </a> here to enter the member page!";
$_SESSION['username'] = $username;
}
else
echo "Incorrect password!";
//code of login
}else
die("That user does not exist!");
//echo $numrows;
}
else
die ("Please enter a username and password!");
?>
