CRUD Insert Data PDO OOP
Hi Web Developer! kali ini guru design akan berbagi tutorial CRUD Insert data berbasis object oriented,. Ok lanjut ke tutorialnya:Buat database dengan nama db_latihanobjek dan tabel dengan nama artikel
CREATE TABLE `artikel` (
`id_artikel` int(5) NOT NULL AUTO_INCREMENT,
`kategori` varchar(20) NOT NULL,
`judul` varchar(20) NOT NULL,
`isi` text NOT NULL;Buat dua folder dengan nama view dan modal
Pada folder view buatlah file artikel.php
artikel.php<?php
error_reporting('~$_NOTICE');
include "../model/class-insert.php";
$auth_artikel = new Insertdata();
//Untuk melakukan eksekusi insert data
if (isset($_POST['kirim'])) {
$kategori = ($_POST['kategori']);
$judul = ($_POST['judul']);
$isi = ($_POST['isi']);
if ($kategori == "") {
$error[] = "kategori kosong!";
}
elseif ($judul == "") {
$error[] = "judul kosong!";
}
elseif ($isi == "") {
$error[] = "isi kosong!";
}
try {
if ($auth_artikel->insertartikel($kategori, $judul, $isi)) {
$auth_artikel->redirect('artikel.php');
}
} catch (PDOException $e) {
echo $e->getMessage();
}
}

<body>
<form method="post">
<select name="kategori" required="">
<option value="">Pilih Kategori</option>
<option value="pendidikan">Pendidikan</option>
<option value="pertanian">Pertanian</option>
<option value="perdagangan">Perdagangan</option>
</select>
<br>
<input type="text" name="judul" placeholder="judul" required="">
<br>
<textarea type="text" name="isi" placeholder="isi"></textarea>
<button type="submit" name="kirim" title="Posting" >Posting</button>
</form>
</body>
</html> Pada folder modal buatlah file koneksi.php dan class-insert.php
koneksi.php<?php
/**

*/
class Database
{
private $hostname = "localhost";
private $db_name = "db_latihanobjek";
private $username = "root";

public $conn;
public function dbConnection()
{
$this->conn = null;
try {
$this->conn =new PDO("mysql:host=" . $this->hostname . ";dbname=" . $this->db_name, $this->username, $this->password);
$this->conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch (PDOException $e) {
echo "Connection error: " . $e->getMessage();
}
return $this->conn;
}
}
?>class-insert.php
<?php
include "koneksi.php";
/**
* Insertdata Class
*/
class Insertdata
{
private $conn;
public function __construct()
{
$database = new Database();
$db = $database->dbConnection();
$this->conn = $db;
}
//star artikel-----------------------------------------------
public function insertartikel($kategori, $judul, $isi)
{
try {
$stmt = $this->conn->prepare('INSERT INTO artikel (kategori, judul, isi VALUES (:1, :2, :3)');
$stmt->bindParam(':1',$kategori);
$stmt->bindParam(':2',$judul);
$stmt->bindParam(':3',$isi);
$stmt->execute();
return $stmt;
} catch (PDOException $e) {
echo $e->getMessage();
}
}
//end artikel-----------------------------------------------
public function redirect($url, $statusCode = 303)
{
header('Location: ' . $url, true, $statusCode);
die();
}
}
?>Sekian Semoga bermanfaat.
