Question

我正在使用Blueimp jQuery文件上传插件上传图片文件。

我正在使用演示中的默认“Basic Plus”并启用了自动上传功能。一旦我将文件放在放置区域上，我就可以看到对server/php/的调用进行文件上传。但文件似乎没有上传。

这是我的代码：

<form>
  <div class="asset_upload has_file js-asset-upload project required">
    <div class="error">
      <div class="message"></div>
    </div>
    <div class="success">
      <div class="image-clip">

      </div>
    </div>
    <div class="upload">
      <input class="photo file" data-help_section="project-image-help" id="fileupload" name="project[photo]" type="file">
      <strong class="center">
        Choose an image from your computer <span class="has_file_hide">This is the main image.</span><span>JPEG, PNG, GIF</span>
      </strong>
      <div class="progress finished">
        <div class="inner">
          <div class="bar" style="width: 100%;">
            <div class="percentage">Processing...</div>
          </div>
        </div>
      </div>
    </div>
  </div>
</form>

                .children()
                .text(file.error);
        }
        if (index + 1 === data.files.length) {
            // data.context.find('button')
            //     .text('Upload')
            //     .prop('disabled', !!data.files.error);
        }
    }).on('fileuploadprogressall', function (e, data) {
        var progress = parseInt(data.loaded / data.total * 100, 10);
        $('.progress').fadeIn();
    }).on('fileuploaddone', function (e, data) {
        alert(data.result.files);
        $.each(data.result.files, function (index, file) {

            if (file.url) {
                var link = $('<a>')
                    .attr('target', '_blank')
                    .prop('href', file.url);
                $(data.context.children()[index])
                    .wrap(link);
            } else if (file.error) {
                var error = $('<span class="text-danger"/>').text(file.error);
                $(data.context.children()[index])
                    .append('<br>')
                    .append(error);
            }
            $('.progress').fadeOut();
        });
    }).on('fileuploadfail', function (e, data) {
        $.each(data.files, function (index) {
            var error = 'File upload failed.';
            $($('.error').children()[index])
                .append('<br>')
                .append(error);
            $('.progress').fadeOut();
        });
    }).prop('disabled', !$.support.fileInput)
        .parent().addClass($.support.fileInput ? undefined : 'disabled');
});

</script>

根据server/php的回复，我可以看到{"files":[]}因此很清楚文件没有上传。

我可以将请求视为https://localhost/dropzone/server/php/index.php?[object%20FormData]&_=1478101410337并将{"files":[]}作为回复。

我对这个插件很新，任何帮助都会受到赞赏。

使用javascript库上传文件无法正常工作。

你需要有代码（在这种情况下是在php文件中）来处理文件上传到达服务器时。除非你有这个，否则只使用你的javascript插件不会工作。
