di mysql jangka

PHP Code:

 ALTER TABLE members ADD hash TEXT ;  ALTER TABLE members ADD accountstatus TINYINT ( 1 ) default 0 ;

kemudian buat file baru yang disebut activate.php

di yang menempatkan

PHP Code:

 <?php // activate.php

Ok, kita langsung masuk saja ke scriptnya. Pertama, buat dulu databasenya dengan nama logreg. Kemudian buat tabel seperti dibawah ini :

 CREATE TABLE `anggota` (
`nama` VARCHAR( 50 ) NOT NULL ,
`email` VARCHAR( 25 ) NOT NULL ,
`userid` VARCHAR( 25 ) NOT NULL ,
`password` VARCHAR( 25 ) NOT NULL ,
PRIMARY KEY ( `userid` )
);

Setelah itu kita buat file untuk koneksi ke database. Ketik script dibawah ini lalu simpan dengan nama connect.php.

<?php
$host = "localhost";
$user = "root"; 
$pass = ""; 
$db = "relogin";  
$konek = mysql_connect($host, $user, $pass) or die ('Koneksi Gagal!');
mysql_select_db($db);
?>

Variabel host,user,pass dan db disesuaikan dengan punya kamu. Host itu adalah nama hostnya, trus user,pass dan db masing-masing adalah username,password dan nama database mysql kamu.
Ok, kalo udah buat juga file-file berikut ini
index.php

<?php
  session_start();
  if(!isset($_SESSION['userid'])) {
  header('location:login.php'); }
  else { $usr = $_SESSION['userid']; }
  require_once("connect.php");
 
  $query = mysql_query("SELECT * FROM anggota WHERE userid = '$usr'");
  $hasil = mysql_fetch_array($query);
?>

 <?php 
  echo "<h2>Selamat Datang, $usr</h2>";

Penjelasan script :
Pada halaman index.php fungsi dari script :

if(!isset($_SESSION['userid'])) {
  header('location:login.php'); }

yakni jika user belum login maka ketika mengakses halaman ini user akan dialihkan ke halaman login.php, sedangkan pada halaman login dan register terdapat script :

if(isset($_SESSION['userid'])) {
  header('location:index.php'); }

berfungsi mengalihkan user yang telah login ke halaman index.php ketika mengakses halaman ini.
