javascript - 多次上传PHP

我试图使用dropzone JS插件和PHP上传多个文件，然后输出每个文件的url。
到目前为止我有这个：

  $upload_dir = 'files';

  for($i=0; $i<count($_FILES['file']['tmp_name']); $i++) {
    $tempFile = $_FILES['file']['tmp_name'][$i];

    $uploadPath = dirname( __FILE__ ) . DIRECTORY_SEPARATOR . $upload_dir . DIRECTORY_SEPARATOR;

    $mainFile = $uploadPath.time().'-'. $_FILES['file']['name'][$i];
     $mainFile_short = time().'-'. $_FILES['file']['name'][$i];

    if(move_uploaded_file($tempFile,$mainFile)) {
    }
  }

不过，我似乎做不到这一点，我不确定哪里出错了。任何想法都很好！

最佳答案

$img = $_FILES['file'];
$upload_dir = 'files';

if(!empty($img))
{
    $img_desc = reArrayFiles($img);
    print_r($img_desc);

    foreach($img_desc as $val)
    {
        $tempFile = $val['tmp_name'];

        $uploadPath = dirname( __FILE__ ) . DIRECTORY_SEPARATOR . $upload_dir . DIRECTORY_SEPARATOR;

        $mainFile = $uploadPath.time().'-'. $val['name'];
        $mainFile_short = time().'-'. $val['name'];

        if(move_uploaded_file($tempFile,$mainFile)) {
        }
    }
}
