Cara Multiple Upload Dengan Codeigniter Dan DropzoneJS

Category: Tips Dan Trik

DropdoneJS adalah sebuah library opensource yang memungkinkan kita untuk mengupload file hanya dengan cara drag dan drop ke zone upload yang sudah kita tentukan, bahkan untuk jenis file gambar bisa ditampilkan preview gambar yang di upload sehingga lebih menarik.

Install Dan Konfigurasi Dasar Codeigniter

Tahap pertama adalah menginstall codeigniter terlebih dahulu, bagi anda yang sudah punya proyek codeigniter dan siap untuk mengimplemetasikan library ini bisa melewati langkah ini tapi jika belum maka silahkan ikuti tahapan dibawah ini :

Download codeigniter pada web www.codeigniter.com
Extrack file CodeIgniter-3.1.0.zip sehingga nanti akan muncul sebuah folder baru dengan nama CodeIgniter-3.1.0
Rename folder CodeIgniter-3.1.0 menjadi ci3 ( atau terserah anda )
Pindahkan folder ci3 ke C:\xampp\htdocs
Pastikan Apache Dan MySQL anda aktif
Silahkan buka web browser anda dan masukan http://localhost/ci3/ pada address bar dan jika berhasil akan muncul halaman welcome codeigniter
langkah selanjutnya adalah kita akan melakukan konfigurasi dasar codeigniter, silahkan buka file config.php yang ada didalam folder application/config kemudian buka dengan software text editor kesayangan anda, silahkan cari script berikut ini :

PHP

$config['base_url'] = '';

1

$config['base_url'] = '';

lalu ubah menjadi seperti ini, silahkan sesuaikan dengan nama folder proyek anda tadi

PHP

$config['base_url'] = 'http://localhost/ci3/';

1

$config['base_url'] = 'http://localhost/ci3/';
selanjutnya silahkan buat folder assets pada root proyek, folder ini nanti akan kita gunakan untuk menampung file CSS Dan Javascript yang digunakan oleh aplikasi, didalam folder assets buat lagi folder css dan js, sehingga struktur folder didalam folder assets sekarang menjadi seperti ini :
Selanjutnya buatlah sebuah folder dengan nama uploads yang akan kita gunakan untuk menyimpan file yang di upload nantinya. sampai tahap ini kita sudah selesai melakukan instalasi dan konfigurasi dasar.

Integrasi DropzoneJS Dengan Codeigniter

langkah selanjutnya adalah mengdownload libray dropzoneJS melalui webiste resminya http://www.dropzonejs.com/.

silahkan copy file dropzone.js tersebut kedalam folder assets/js. lalu buatlah sebuah file css baru dengan nama dropzone.css dan simpan di dalam folder assets/css. isi dari script dropzone.css ini adalah :

Membuat Controller Dan View

Pada tahap ini kita akan membuat sebuah controller dengan nama Upload.php yang kita simpan dalam folder Application/Controller, lalu setelah itu silahkan tulis script ini :

<?php

class Upload extends CI_Controller {

    function __construct() {
        parent::__construct();
        $this->load->helper(array('form','url'));
    }

    function index() {
        $this->load->view('dropzonejs');
    }

    function do_upload() {
        $config['upload_path'] = './uploads/';
        $this->load->library('upload', $config);
        $this->upload->do_upload('file');
        $data = $this->upload->data();
    }

}

<?php

class Upload extends CI_Controller {

function __construct() {

parent::__construct();

$this->load->helper(array('form','url'));

}

function index() {

$this->load->view('dropzonejs');

}

function do_upload() {

$config['upload_path'] = './uploads/';

$this->load->library('upload', $config);

$this->upload->do_upload('file');

$data = $this->upload->data();

}

selanjutnya kita akan membuat sebuah file dengan nama dropzone.php yang disimpan dalam folder Application/Views, file ini yang akan menjadi interface pengguna untuk mengupload nantinya, jika sudah membuat file nya silahkan ketik script ini :

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" lang="en">
    <head>
        <title>Tutorial Belajarphp.net</title
        <!-- Add Dropzone -->
        <script src="<?php echo base_url() ?>assets/js/dropzone.js"></script>
        <link rel="stylesheet" href="<?php echo base_url() ?>assets/css/dropzone.css">
    </head>
    <body>
        <h1>Upload Multiple Files Menggunakan DropzoneJS and Codeigniter</h1>
        <div class="image_upload_div">
            <?php echo form_open('upload/do_upload', "class='dropzone'"); ?>

            </form>
        </div> 	
    </body>
</html>

<!DOCTYPE html>

<head>

<title>Tutorial Belajarphp.net</title

</head>

<body>

<h1>Upload Multiple Files Menggunakan DropzoneJS and Codeigniter</h1>

<?php echo form_open('upload/do_upload', "class='dropzone'"); ?>

</form>

</div>

</body>

</html>

Implementasi Dan Pengujian

silahkan buka web browser anda dan masukan http://localhost/ci3/index.php/upload pada addressbar sehinga muncul tampilan seperti ini :silahkan klik pada area ” drop filde hre to upload ” untuk memilih beberapa file yang akan kamu uploadlalu silahkan chek di folder uploads tadi maka seharusnya file yang kamu upload tadi sudah ada disana
