Sebelum memulai pastikan
apache2 apt install apache2
mariadb apt install mariadb-server
dns server apt install bind9
dan
php apt install php php-{fpm,common,mbstring,xmlrpc,soap,gd,xml,intl,mysql,cli,mcrypt,ldap,zip,curl} -y
, dan virtualhost sudah terinstall dengan baik
Siapkan Database
masuk ke mariadb
lalu ketikkan perintah berikut
mariadb (enter) CREATE DATABASE organisasi_siswa; CREATE USER 'siswa'@'localhost' IDENTIFIED BY '12345'; GRANT ALL PRIVILEGES ON organisasi_siswa.* TO 'siswa'@'localhost'; USE organisasi_siswa; CREATE TABLE siswa ( id INT AUTO_INCREMENT PRIMARY KEY, nama VARCHAR(100) NOT NULL, kelas VARCHAR(25) NOT NULL, no_hp VARCHAR(15) NOT NULL, riwayat_organisasi TEXT NOT NULL, jabatan VARCHAR(50) NOT NULL, tahun_ajaran VARCHAR(9) NOT NULL );
masuk ke folder var/www/html/xitkj1.web1 lalu,
Buaf file config.php
isi dengan kode berikut
<?php // config.php $host = 'localhost'; $dbname = 'organisasi_siswa'; $username = 'siswa'; // sesuaikan dengan username MariaDB Anda $password = '12345'; // sesuaikan dengan password MariaDB Anda try { $pdo = new PDO("mysql:host=$host;dbname=$dbname", $username, $password); $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); } catch (PDOException $e) { die("Koneksi gagal: " . $e->getMessage()); } ?>
Buat file index.php
<?php
include 'config.php';
// Mendapatkan kata kunci dari form pencarian jika ada
$search = isset($_GET['search']) ? $_GET['search'] : '';
// Tentukan berapa banyak data yang ditampilkan per halaman
$limit = 5;
// Dapatkan halaman saat ini dari URL, jika tidak ada, default ke 1
$page = isset($_GET['page']) ? (int)$_GET['page'] : 1;
$offset = ($page - 1) * $limit;
// Query untuk menghitung total data
$totalQuery = $pdo->query("SELECT COUNT(*) FROM siswa" . ($search ? " WHERE nama LIKE '%$search%' OR kelas LIKE '%$search%'" : ""));
$totalData = $totalQuery->fetchColumn();
$totalPages = ceil($totalData / $limit);
// Query untuk mengambil data siswa dengan paginasi
if ($search) {

$query->bindValue(1, "%$search%");
$query->bindValue(2, "%$search%");
$query->bindValue(':limit', $limit, PDO::PARAM_INT);
$query->bindValue(':offset', $offset, PDO::PARAM_INT);
$query->execute();
} else {
