Dropzone.js-显示服务器上的现有文件

ajax

我目前正在使用dropzone.js v3.10.2，但在显示已上传的现有文件时遇到问题。我比php更加胜任，但是关于ajax和js的知识却很有限

如果您能帮助的话，那太好了

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

<?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

我检查了代码（来自starTutorial），它对我也不起作用（？）

我设法通过替换它来使其工作：

$.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与提示栏一起显示。要解决此问题，请添加：

thisDropzone.emit("complete", mockFile);
