Loncat ke navigasi Loncat ke pencarian

Sebelum memulai pastikan apache2, mariadb, dan php, dan virtualhost sudah terinstall dengan baik

Siapkan Database

masuk ke mariadb lalu ketikkan perintah berikut

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 = $pdo->prepare("SELECT * FROM siswa WHERE nama LIKE ? OR kelas LIKE ? LIMIT :limit OFFSET :offset");

    $query->bindValue(1, "%$search%");

    $query->bindValue(2, "%$search%");

    $query->bindValue(':limit', $limit, PDO::PARAM_INT);

    $query->bindValue(':offset', $offset, PDO::PARAM_INT);

    $query->execute();

} else {

    $query = $pdo->prepare("SELECT * FROM siswa LIMIT :limit OFFSET :offset");

    $query->bindValue(':limit', $limit, PDO::PARAM_INT);

    $query->bindValue(':offset', $offset, PDO::PARAM_INT);

    $query->execute();

}

$siswa = $query->fetchAll(PDO::FETCH_ASSOC);
