<script type="text/javascript">

Dropzone.autoDiscover = false;

$(".dropzone").dropzone({

init: function() {

myDropzone = this;

$.ajax({

url: 'uploadFile.php',

type: 'post',

data: {request: 'fetch'},

dataType: 'json',

success: function(response){

$.each(response, function(key,value) {

var mockFile = { name: value.name, size: value.size};

myDropzone.emit("addedfile", mockFile);

myDropzone.emit("thumbnail", mockFile, value.path);

myDropzone.emit("complete", mockFile);

});

}

});

}

});

</script>

</body>

</html>

$msg = "";

if (move_uploaded_file($_FILES["file"]["tmp_name"], $targetDir.$_FILES['file']['name'])) {

$msg = "Successfully uploaded";

}else{

$msg = "Error while uploading";

}

echo $msg;

exit;

}

/* Read files from */

if($request == 'fetch'){

$fileList = [];

$dir = $targetDir;

if (is_dir($dir)){

if ($dh = opendir($dir)){

while (($file = readdir($dh)) !== false){

if($file != '' && $file != '.' && $file != '..'){

$file_path = $targetDir.$file;

if(!is_dir($file_path)){

$size = filesize($file_path);

$fileList[] = ['name'=>$file, 'size'=>$size, 'path'=>$file_path];

}

}
