Membuat Aplikasi Database Sederhana

Dari Dokumentasi Robie
Loncat ke navigasi Loncat ke pencarian

Sebelum memulai pastikan apache2, mariadb, dan php 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(15) NOT NULL,
    no_hp VARCHAR(15) NOT NULL,
    riwayat_organisasi TEXT NOT NULL,
    jabatan VARCHAR(50) NOT NULL,
    tahun_ajaran VARCHAR(9) NOT NULL
);

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'; 

$query = $pdo->query("SELECT * FROM siswa");
//$siswa = $query->fetchAll(PDO::FETCH_ASSOC);

// Mendapatkan kata kunci dari form pencarian jika ada
$search = isset($_GET['search']) ? $_GET['search'] : ;

// Query dengan kondisi pencarian jika kata kunci ada
if ($search) {
    $query = $pdo->prepare("SELECT * FROM siswa WHERE nama LIKE ? OR kelas LIKE ?");
    $query->execute(["%$search%", "%$search%"]);
} else {
    $query = $pdo->query("SELECT * FROM siswa");
}

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