Panduan ini menunjukkan cara mengirim dan menyimpan data formulir ke database MySQL setelah pengiriman menggunakan PHP. Diperlukan pemahaman dasar tentang MySQL dan PHP

Show

Mari kita mulai

  1. Buat database dan tabel Anda
    Kolom di tabel Anda akan bergantung pada struktur formulir Anda. Lihat panduan ini untuk melihat nama bidang formulir atau kunci pos jika Anda tidak yakin kolom apa yang akan ditambahkan ke tabel database Anda
  2. Untuk panduan ini, pastikan untuk menambahkan kolom “submission_id” di tabel Anda
    Dalam contoh formulir kontak ini, tabelnya terlihat seperti berikut di phpMyAdmin

Catatan. Proses untuk membuat atau mengedit database Anda akan bergantung pada penyiapan server atau host web Anda. Hubungi dukungan penyedia Anda untuk mendapatkan bantuan

Operasi basis data dalam PHP adalah hal yang sangat krusial yang sangat dibutuhkan dalam operasi CRUD (Create, Read, Update dan Delete).

Pada artikel ini, kita akan membahas Baca bagian i. e. pengambilan data dari database

Ada dua cara untuk terhubung ke database menggunakan PHP. Mereka adalah sebagai berikut

  1. MySQLi ("i" berarti ditingkatkan)
  2. PDO (Objek Data PHP)

MySQLi vs PDO. Kedua cara tersebut sangat bagus tetapi hanya ada satu perbedaan antara kedua metode tersebut, PDO dapat bekerja pada 12 sistem database yang berbeda sedangkan MySQLi hanya bekerja dengan database MySQL

Menghubungkan ke Database

  • Berorientasi Objek MySQLi

    $conn = new mysqli($servername, $username, $databasename)

  • Prosedural MySQLi

    $conn = mysqli_connect($servername, 
    $username, $password, $databasename);
    _

  • PDO

    $conn = new PDO("mysql:host=$servername;dbname=myDB",
    $username, $password, $databasename);

Menjalankan Query. Setelah terhubung ke database, kita perlu menjalankan kueri untuk mengambil data. Dalam operasi Baca, kami hanya akan menggunakan kueri pemilihan untuk mengambil data dari database

  • Berorientasi Objek MySQLi

    $conn->query($query);

  • Prosedural MySQLi

    mysqli_query($conn, $query)
    _

  • PDO

    $stmt = $conn->prepare($query);
$stmt->execute();

Tutup Koneksi. Setelah pengambilan dilakukan, Anda harus menutup koneksi ke database menggunakan fungsi close()

$conn->close();
_

Contoh Basis Data

Buat Tabel di database

CREATE TABLE `Student Details` (
  `Roll_No` int(11) NOT NULL,
  `Name` varchar(255) NOT NULL,
  `City` varchar(255) NOT NULL,
  `Age` int(11) NOT NULL,
  PRIMARY KEY (`Roll_No`)
);
