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.
Membuat Form upload
langkah pertama kita akan membuat sebuah file baru dengan nama index.php, file ini yang nantinya sebagai interface yang akan kita gunakan untuk mengupload file.

<!— Add Dropzone —>
<link rel=“stylesheet” type=“text/css” href=“css/dropzone.css” />
<script type=“text/javascript” src=“js/dropzone.js”></script>
</head>
<body>
<h1>Upload Multiple Files Menggunakan DropzoneJS and PHP</h1>
<div class=“image_upload_div”>
<form action=“upload.php” class=“dropzone”>
</form>
</div>
</body>
</html>
|
selanjutnya silahkan buat sebuah folder dengan nama uploads, folder ini nantinya akan menampung file yang sudah di upload oleh pengguna sistem sehingga struktur foldernya menjadi seperti ini.
langkah selanjutnya adalah membuat file dropzone.css yang akan memberikan style pada zona yang akan digunakan untuk mendrag file yang akan di upload.

|

2
3
4
5
6
7
8
|
<?php
if (!empty($_FILES)) {
$targetDir = “uploads/”;
$fileName = $_FILES[‘file’][‘name’];
$targetFile = $targetDir . $fileName;
move_uploaded_file($_FILES[‘file’][‘tmp_name’], $targetFile);
}
?>
|
dengan menggunakan library dropzoneJS ini maka sekarang proses upload file lebih menarik dan interaktif. anda bisa mendownload source code nya disini.
