Tutorial CRUD Dengan Menggunakan AJAX, JQuery, PHP Dan MySQL

AJAX adalah singkatan dari Asynchronous JavaScript and XML. AJAX adalah teknik baru untuk menciptakan aplikasi web yang lebih baik, lebih cepat, dan lebih interaktif dengan bantuan XML, HTML, CSS, dan Java Script. Dengan AJAX, saat Anda menekan submit pada form, JavaScript akan membuat permintaan ke server, menampilkan hasilnya, dan memperbarui layar pada saat itu juga. Dalam kata lain, pengguna tidak akan pernah tahu bahwa ada data dikirim ke server.

Dalam tutorial ini, kita akan mengetahui bagaimana cara kerja dari AJAX dan bagaimana mengkombinasikannya dengan PHP dan MySQL untuk membuat halaman website yang lebih interaktif tanpa perlu merefresh halaman. Seperti pada tutorial-tutorial sebelumnya, kita akan menggunakan virtual host seperti di sini.

Pertama-tama kita akan membuat database dengan nama database : db_belajar, kemudian buat table : tb_user dengan script seperti di bawah ini

CREATE TABLE IF NOT EXISTS `tb_user` (
  `user_id` int(5) NOT NULL AUTO_INCREMENT,
  `user_name` varchar(50) NOT NULL,
  `user_email` varchar(50) NOT NULL,
  `user_address` varchar(50) NOT NULL,
  PRIMARY KEY (`user_id`)
) ENGINE=INNODB  DEFAULT CHARSET=latin1 AUTO_INCREMENT=1;

CREATE TABLE IF NOT EXISTS `tb_user` (

`user_id` int(5) NOT NULL AUTO_INCREMENT,

`user_name` varchar(50) NOT NULL,

`user_email` varchar(50) NOT NULL,

`user_address` varchar(50) NOT NULL,

PRIMARY KEY (`user_id`)

) ENGINE=INNODB DEFAULT CHARSET=latin1 AUTO_INCREMENT=1;

Kemudian buat halaman index.php sebagai halaman utama dari aplikasi yang akan dibuat :

Buat folder baru untuk menyimpan file-file PHP sebagai API dari aplikasi, misalnya nama folder adalah api. File pertama yang dibuat tentunya untuk menghubungkan dengan database db_belajar yang telah dibuat sebelumnya.

config_db.php

define("DB_USER", "root");
define("DB_PASSWORD", "");
define("DB_DATABASE", "db_belajar");
define("DB_HOST", "localhost");
$mysqli = new mysqli(DB_HOST, DB_USER, DB_PASSWORD, DB_DATABASE);

define("DB_USER", "root");

define("DB_PASSWORD", "");

define("DB_DATABASE", "db_belajar");

define("DB_HOST", "localhost");

$mysqli = new mysqli(DB_HOST, DB_USER, DB_PASSWORD, DB_DATABASE);

Buat file read.php untuk menampikan data dari database

header("Content-type:application/json");
require 'db_config.php';
$num_rec = 10;
if (isset($_GET['page'])) {
    $page = $_GET['page'];
} else {
    $page = 1;
};
$start_from = ($page - 1) * $num_rec;
$sqlTotal = "SELECT * FROM tb_user";
$sql = "SELECT * FROM tb_user Order By user_id desc LIMIT $start_from, $num_rec";
$result = $mysqli->query($sql);
while ($row = $result->fetch_assoc()) {
    $json[] = $row;
}
$data['data'] = $json;
$result = mysqli_query($mysqli, $sqlTotal);
$data['total'] = mysqli_num_rows($result);
echo json_encode($data, JSON_PRETTY_PRINT);

header("Content-type:application/json");

require 'db_config.php';

$num_rec = 10;

if (isset($_GET['page'])) {

$page = $_GET['page'];

} else {

$page = 1;

};

$start_from = ($page - 1) * $num_rec;

$sqlTotal = "SELECT * FROM tb_user";

$sql = "SELECT * FROM tb_user Order By user_id desc LIMIT $start_from, $num_rec";

$result = $mysqli->query($sql);

while ($row = $result->fetch_assoc()) {

$json[] = $row;

}

$data['data'] = $json;

$result = mysqli_query($mysqli, $sqlTotal);

$data['total'] = mysqli_num_rows($result);

echo json_encode($data, JSON_PRETTY_PRINT);

Buat file create.php untuk memproses penambahan data

header("Content-type:application/json");
require 'db_config.php';
$sql = "INSERT INTO tb_user (user_name,user_email,user_address) VALUES ('" . $_POST['user_name'] . "','" . $_POST['user_email'] . "','" . $_POST['user_address'] . "')";
$result = $mysqli->query($sql);
$sql = "SELECT * FROM tb_user Order by user_id desc LIMIT 1";
$result = $mysqli->query($sql);
$data = $result->fetch_assoc();
echo json_encode($data, JSON_PRETTY_PRINT);

header("Content-type:application/json");

require 'db_config.php';

$sql = "INSERT INTO tb_user (user_name,user_email,user_address) VALUES ('" . $_POST['user_name'] . "','" . $_POST['user_email'] . "','" . $_POST['user_address'] . "')";

$result = $mysqli->query($sql);

$sql = "SELECT * FROM tb_user Order by user_id desc LIMIT 1";

$result = $mysqli->query($sql);

$data = $result->fetch_assoc();

echo json_encode($data, JSON_PRETTY_PRINT);

Buat file update.php untuk meng-update data

header("Content-type:application/json");
require 'db_config.php';
$sql = "UPDATE tb_user SET user_name = '" . $_POST['user_name'] . "',user_email = '" . $_POST['user_email'] . "',user_address = '" . $_POST['user_address'] . "' WHERE user_id = '" . $_POST['user_id'] . "'";
$result = $mysqli->query($sql);
$sql = "SELECT * FROM tb_user WHERE user_id = '" . $_POST['user_id'] . "'";
$result = $mysqli->query($sql);
$data = $result->fetch_assoc();
echo json_encode($data, JSON_PRETTY_PRINT);

header("Content-type:application/json");

require 'db_config.php';

$sql = "UPDATE tb_user SET user_name = '" . $_POST['user_name'] . "',user_email = '" . $_POST['user_email'] . "',user_address = '" . $_POST['user_address'] . "' WHERE user_id = '" . $_POST['user_id'] . "'";

$result = $mysqli->query($sql);

$sql = "SELECT * FROM tb_user WHERE user_id = '" . $_POST['user_id'] . "'";

$result = $mysqli->query($sql);

$data = $result->fetch_assoc();

echo json_encode($data, JSON_PRETTY_PRINT);

Buat file delete.php untuk menhapus data

header("Content-type:application/json");
require 'db_config.php';
$sql = "DELETE FROM tb_user WHERE user_id = '" . $_POST['user_id'] . "'";
$result = $mysqli->query($sql);
echo json_encode([$_POST['user_id']], JSON_PRETTY_PRINT);

header("Content-type:application/json");

require 'db_config.php';

$sql = "DELETE FROM tb_user WHERE user_id = '" . $_POST['user_id'] . "'";

$result = $mysqli->query($sql);

echo json_encode([$_POST['user_id']], JSON_PRETTY_PRINT);

Kemudian buat file javascript dengan nama : ajax.js untuk menghubungkan halaman utama dengan API, kode sumbernya seperti di bawah ini :

$( document ).ready(function() {

var url = "http://www.belajar.local/AJAX-CRUD/";
var page = 1;
var current_page = 1;
var total_page = 0;
var is_ajax_fire = 0;

manageData();

/* tampilkan data */
function manageData() {
    $.ajax({
        dataType: 'json',
        url: url+'api/read.php',
        data: {page:page}
    }).done(function(data){
    	total_page = Math.ceil(data.total/10);
    	current_page = page;

    	$('#pagination').twbsPagination({
	        totalPages: total_page,
	        visiblePages: current_page,
	        onPageClick: function (event, pageL) {
	        	page = pageL;
                if(is_ajax_fire != 0){
	        	  getPageData();
                }
	        }
	    });

    	manageRow(data.data);
        is_ajax_fire = 1;

    });

}

/* tampilkan  data */
function getPageData() {
	$.ajax({
    	dataType: 'json',
    	url: url+'api/read.php',
    	data: {page:page}
	}).done(function(data){
		manageRow(data.data);
	});
}


/* tambahkan data baru pada table */
function manageRow(data) {
	var	rows = '';
	$.each( data, function( key, value ) {
	  	rows = rows + '<tr>';
	  	rows = rows + '<td>'+value.user_name+'</td>';
	  	rows = rows + '<td>'+value.user_email+'</td>';
                rows = rows + '<td>'+value.user_address+'</td>';
	  	rows = rows + '<td data-id="'+value.user_id+'">';
        rows = rows + '<button data-toggle="modal" data-target="#edit-user" class="btn btn-primary btn-sm edit-user"> <span class="glyphicon glyphicon-pencil" aria-hidden="true"></span> Edit</button> ';
        rows = rows + '<button class="btn btn-danger btn-sm remove-user"><span class="glyphicon glyphicon-remove" aria-hidden="true"></span> Hapus</button>';
        rows = rows + '</td>';
	  	rows = rows + '</tr>';
	});

	$("tbody").html(rows);
}

/* tambah user */
$(".crud-submit").click(function(e){
    e.preventDefault();
    var form_action = $("#create-user").find("form").attr("action");
    var user_name = $("#create-user").find("input[name='user_name']").val();
    var user_email = $("#create-user").find("input[name='user_email']").val();

            $(".modal").modal('hide');
            alert('Data berhasil ditambah')
        });
    }else{
        alert('Ada data yang kosong')
    }


});

/* hapus user */
$("body").on("click",".remove-user",function(){

    var c_obj = $(this).parents("tr");

    $.ajax({
