Membuat Aplikasi Database Sederhana

Dari Dokumentasi Robie
Loncat ke navigasi Loncat ke pencarian

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 = $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);

Download file css dan js

masih di folder xitkj1.web1

download file css js dengan mengetikkan perintah

wget https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css enter

Menambahkan Data baru ke Database

masuk ke mariadb lalu isi data ke dalam tabel siswa dengan ketikkan perintah berikut

USE organisasi_siswa;
