Php dropzone post文件和数据

我有一个问题时，发送我的文件，这些最后不张贴

<div class="container"><form role="form" method="post" action="upload.php" class="dropzone" id="mydropzone" enctype="multipart/form-data">
<input type="hidden" name="additionaldata" value="1" /> 
<div class="form-group">
  <label  for="email">De</label>
  <input type="email" class="form-control "  name="email" placeholder="user@example.com" required />
  <span class="icon fa fa-envelope fa-lg"></span>
</div>
<div class="form-group">
  <label for="sub">Sujet</label>
  <input type="text" class="form-control "  name="sujet" placeholder="Sujet" required/>
  <span class="icon fa fa-pencil fa-lg"></span>
</div>
<div class="form-group">
  <textarea rows="5" cols="30"  name="msg" placeholder="Bonjour, insérer votre Message" style="width:100%"></textarea>
  <span class="icon-textarea fa fa-paper-plane fa-lg "></span>
</div>
<div class="dropzone-previews"></div>
<div><button id="submit-all" type="submit" class="btn btn default">Submit</button>
</div>
</form>

检查帖子的my upload.php

<?php

if(!empty($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest') 
{
    echo "RECEIVED ON SERVER: \n";
    echo "FILES: \n";
    print_r($_FILES);
    echo "\$_POST: \n";
    print_r($_POST);
}

您需要在
successmultiple
或
errormultiple
事件中访问服务器的响应：

例如，要在控制台中显示响应：

this.on("successmultiple", function(files, response) {
    console.log(response);
});
this.on("errormultiple", function(files, response) {
    console.log(response);
});

this.on("successmultiple", function(files, response) {
    console.log(response);
});
this.on("errormultiple", function(files, response) {
    console.log(response);
});
