的index.php
<html>
<head>
<link href="css/dropzone.css" type="text/css" rel="stylesheet" />
<script src="ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script src="dropzone.min.js"></script>
<script>
Dropzone.options.myDropzone = {
init: function() {
thisDropzone = this;
$.get('upload.php', function(data) {
$.each(data, function(key,value){
var mockFile = { name: value.name, size: value.size };
thisDropzone.options.addedfile.call(thisDropzone, mockFile);
thisDropzone.options.thumbnail.call(thisDropzone, mockFile, "uploads/"+value.name);
});
});
}
};
</script>
</head>
<body>
<form action="upload.php" class="dropzone" id="my-dropzone"></form>
</body>
upload.php的
<?php
$ds = DIRECTORY_SEPARATOR;
$storeFolder = 'uploads';
if (!empty($_FILES)) {
$tempFile = $_FILES['file']['tmp_name'];
$targetPath = dirname( __FILE__ ) . $ds. $storeFolder . $ds;
$targetFile = $targetPath. $_FILES['file']['name'];
move_uploaded_file($tempFile,$targetFile);
} else {
$result = array();
$files = scandir($storeFolder); //1
if ( false!==$files ) {
foreach ( $files as $file ) {
if ( '.'!=$file && '..'!=$file) { //2
$obj['name'] = $file;
$obj['size'] = filesize($storeFolder.$ds.$file);
$result[] = $obj;
}
}
}
header('Content-type: text/json'); //3
header('Content-type: application/json');
echo json_encode($result);
}
?>
PS.我知道php正在检索数据

到目前为止给出的解决方案不适用于dropzone 版本 5.x。对我有用的是修改 dropzone 的配置选项，如下所示：
init: function () {
var mockFile = {
name: 'FileName',
size: '1000',
type: 'image/jpeg',
accepted: true // required if using 'MaxFiles' option
};
this.files.push(mockFile); // add to files array
this.emit("addedfile", mockFile);
this.emit("thumbnail", mockFile, 'http://url/to/file');
this.emit("complete", mockFile);
}
这个概念是，创建一个模拟文件，并调用事件处理程序addedfile并thumbnail绘制预览。然后最后调用complete事件以确保没有显示进度条等。

我检查了代码(来自starTutorial)它对我来说也不起作用(？)
我设法通过替换它来使它工作:
$.get('upload.php', function(data) {
$.each(data, function(key,value) {
var mockFile = { name: value.name, size: value.size };
thisDropzone.options.addedfile.call(thisDropzone, mockFile);
thisDropzone.options.thumbnail.call(thisDropzone, mockFile, "uploads/"+value.name);
});
});
有了这个:
$.getJSON('files/list-all', function(data) {
$.each(data, function(index, val) {
var mockFile = { name: val.name, size: val.size };
thisDropzone.options.addedfile.call(thisDropzone, mockFile);
thisDropzone.options.thumbnail.call(thisDropzone, mockFile, "uploads/" + val.name);
});
});

编辑:在4.0版中,现有文件的缩略图将显示在其中的提示栏.解决这个问题:
thisDropzone.emit("complete", mockFile);
