1.pertama kita harus membuat databasenya terlebih dahulu,kira" kayak gini
kodingnya,kurang lebih seperti berikut:
<?php
mysql_connect('localhost','root','')or die('anda gagal');
mysql_select_db('input')or die('database salah');
?>
3.kita membuat form loginnya ,kira-kira seperti dibawah ini:
<<!DOCTYPE html>
<html>
<head>
<title>login</title>
</head>
<body>
<h1>login</h1>
<form action="" method="port">
<label>username<tr/>:</label>
<input id="name" name="username" placeholder="username" type="text"><br/>
<label>password<tr/>:</label>
<input id="password" name="pass" type="password" placeholder="password">
<br>
<input type="submit" name="submit" id="submit" value="login">
<input type="reset" name="hapus" id="reset" value="hapus">
</body>
</html>
4.jika sudah sekarang kita buat lagi cek_login.php
<?
include"koneksi.php";
$user=$_POST['username'];
$pass=$_POST['password'];
$login=mysql_query("select*from login where
username='$username' and passwor='$password'");
$ini=mysql_num_rows($login);
$itu=mysql_fetch_array($login);
if($ini > 0)
{
session_start();
session_register('username');
session_register('password');
$_SESSION[username]=$ itu[username];
$_SESSION[password]=$ itu[password];
echo"<script>window.location='selamat.php';</script>";
}
else
{
echo"<br><center>Login anda gagal, silahkan<br>
<a href=login.php>Ulangi Lagi!</a></center>";}
?>
4.langkah selanjutnya tinggal membuat file selamat.php
<?
session_start();
if(empty($_SESSION[username]) AND
empty($_SESSION[password]))
{
echo"maf anda haarus login";
echo"<a href=login.php>login!</a></center>";
}
else
{
?>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
<title>::Administrator::</title>
<style type="text/css">
<!--
body {
background-image: url(images/bg.jpg);
}
</head>
<body>
<h2><marquee behavior="alternate"direction="left">
<span class="style7"><br />
Selamat Datang di halamanadministrator FOUR I_Q BAND
</span>
</marquee>
< a href=”logout.php”>Logout</a>
</body>
</html>
<?php
}?>
5.okech,sekarang tinggal membuat file logout.php
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html;charset=iso-8859-1" />
<title>Untitled Document</title>
</head>
<body>
<?
session_start();
session_unregister(' username ');
session_unregister(' password ');
session_destroy();
echo"<meta http-equiv='refresh' content='0;url=index.php'>";
exit;
?>
</body>
</html>
okech demikian dulu ya dari anee,jika ada kekurangan mohon dimaklumi , dan jika ada kelebihan silahkan diambil saja ,kita kan masih sama sama belajar,
