Jquery文件上载-$\u文件数组为空

Jquery文件上载-$\u文件数组为空,jquery,jquery-file-upload,Jquery,Jquery File Upload,使用Jquery上传文件。它正在“工作”并上传图像和显示拇指。但是，当我在处理程序中提交表单时，如果我转储$\u文件，那里什么都没有 <div class="control-group"> <label class="required control-label" for="first_name">Comments <span class="required">*</span></label>

使用Jquery上传文件。它正在“工作”并上传图像和显示拇指。但是，当我在处理程序中提交表单时，如果我转储$\u文件，那里什么都没有

        <div class="control-group">

            <div class="controls">

我基本上使用的是Basic Plus示例，autoUpload设置为false。我希望我能够使用它让用户选择多个图像。然后在表单提交后将其上传，处理方式基本上与我在页面上有X个文件上传按钮时的处理方式相同

        <div class="control-group">
            <label class="required control-label" for="first_name">Comments <span class="required">*</span></label>
            <div class="controls">
                <textarea name="comments" cols="40" rows="10" class="span8 required" id="comments" ></textarea>             </div>
        </div>



        <!-- The fileinput-button span is used to style the file input field as button -->
<span class="btn btn-success fileinput-button">
    <i class="glyphicon glyphicon-plus"></i>
    <span>Add files...</span>
    <!-- The file input field used as target for the file upload widget -->
    <input id="fileupload" type="file" name="files[]" multiple>
</span>
<br>
<br>
<!-- The global progress bar -->
<div id="progress" class="progress">
    <div class="progress-bar progress-bar-success"></div>
</div>

<div id="files" class="files"></div>

        <div class="form-actions" style="">
            <input type="submit" value="Submit Review" name="submitReview" class="btn btn-primary btn-large">
        </div>
        </form>
使用autoUpload=TRUE上传也可以。我试过了，也没有在帖子或文件中看到任何东西

        <div class="control-group">
            <label class="required control-label" for="first_name">Comments <span class="required">*</span></label>
            <div class="controls">
                <textarea name="comments" cols="40" rows="10" class="span8 required" id="comments" ></textarea>             </div>
        </div>

        </form>
让这两种方法都能发挥作用的评论将是非常好的

        <div class="control-group">
            <label class="required control-label" for="first_name">Comments <span class="required">*</span></label>

添加文件。。。
通过为上传的每个文件添加一个隐藏的输入，我可以处理它们，并在表单提交后将它们添加到数据库中，从而使其正常工作

        <div class="control-group">
            <label class="required control-label" for="first_name">Comments <span class="required">*</span></label>
            <div class="controls">
                <textarea name="comments" cols="40" rows="10" class="span8 required" id="comments" ></textarea>             </div>
        </div>



        <!-- The fileinput-button span is used to style the file input field as button -->
<span class="btn btn-success fileinput-button">
    <i class="glyphicon glyphicon-plus"></i>
    <span>Add files...</span>
    <!-- The file input field used as target for the file upload widget -->
    <input id="fileupload" type="file" name="files[]" multiple>
</span>
<br>
<br>
<!-- The global progress bar -->
<div id="progress" class="progress">
    <div class="progress-bar progress-bar-success"></div>
</div>
<!-- The container for the uploaded files -->
<div id="files" class="files"></div>
<br>



        <div class="form-actions" style="">
            <input type="submit" value="Submit Review" name="submitReview" class="btn btn-primary btn-large">
        </div>
        </form>
我觉得应该有一些内置的东西来处理这个问题，但现在这个工作

        <div class="control-group">
            <label class="required control-label" for="first_name">Comments <span class="required">*</span></label>
            <div class="controls">
                <textarea name="comments" cols="40" rows="10" class="span8 required" id="comments" ></textarea>             </div>
        </div>



        <!-- The fileinput-button span is used to style the file input field as button -->
<span class="btn btn-success fileinput-button">
    <i class="glyphicon glyphicon-plus"></i>
    <span>Add files...</span>
    <!-- The file input field used as target for the file upload widget -->
    <input id="fileupload" type="file" name="files[]" multiple>
</span>
<br>
<br>
<!-- The global progress bar -->
<div id="progress" class="progress">
    <div class="progress-bar progress-bar-success"></div>
</div>
<!-- The container for the uploaded files -->
<div id="files" class="files"></div>
<br>



        <div class="form-actions" style="">
            <input type="submit" value="Submit Review" name="submitReview" class="btn btn-primary btn-large">
        </div>
        </form>
添加了一个FileHidden div来保存隐藏字段

        <div class="control-group">
            <label class="required control-label" for="first_name">Comments <span class="required">*</span></label>
            <div class="controls">
                <textarea name="comments" cols="40" rows="10" class="span8 required" id="comments" ></textarea>             </div>
        </div>



        <!-- The fileinput-button span is used to style the file input field as button -->
<span class="btn btn-success fileinput-button">
    <i class="glyphicon glyphicon-plus"></i>
    <span>Add files...</span>
    <!-- The file input field used as target for the file upload widget -->
    <input id="fileupload" type="file" name="files[]" multiple>
</span>
<br>
<br>
<!-- The global progress bar -->
<div id="progress" class="progress">
    <div class="progress-bar progress-bar-success"></div>
</div>
<!-- The container for the uploaded files -->
<div id="files" class="files"></div>
<br>



        <div class="form-actions" style="">
            <input type="submit" value="Submit Review" name="submitReview" class="btn btn-primary btn-large">
        </div>
        </form>

<div id="files" class="files"></div>
然后更新了js，其中附加了一个带有文件名的隐藏输入，以传递给我的表单处理程序，这样我就可以将图像与表单提交链接起来

        <div class="control-group">
            <label class="required control-label" for="first_name">Comments <span class="required">*</span></label>
            <div class="controls">
                <textarea name="comments" cols="40" rows="10" class="span8 required" id="comments" ></textarea>             </div>
        </div>



        <!-- The fileinput-button span is used to style the file input field as button -->
<span class="btn btn-success fileinput-button">
    <i class="glyphicon glyphicon-plus"></i>
    <span>Add files...</span>
    <!-- The file input field used as target for the file upload widget -->
    <input id="fileupload" type="file" name="files[]" multiple>
</span>
<br>
<br>
<!-- The global progress bar -->
<div id="progress" class="progress">
    <div class="progress-bar progress-bar-success"></div>
</div>
<!-- The container for the uploaded files -->
<div id="files" class="files"></div>
<br>



        <div class="form-actions" style="">
            <input type="submit" value="Submit Review" name="submitReview" class="btn btn-primary btn-large">
        </div>
        </form>

}).on('fileuploaddone', function (e, data) {
        $.each(data.result.files, function (index, file) {
            if (file.url) {
                $( "#filesHidden" ).append( '<input type="hidden" name="images[]" value="' + file.name + '">' );
            } else if (file.error) {
                var error = $('<span class="text-danger"/>').text(file.error);
                $(data.context.children()[index])
                    .append('<br>')
                    .append(error);
            }
    });
        }

}）.on（'fileuploaddone'，函数（e，数据）{
$.each（data.result.files，函数（索引，文件）{
if（file.url）{
$（“#文件隐藏”）.append（“”）；
}else if（file.error）{
var error=$（''）.text（file.error）；
$（data.context.children（）[index]）
.append（“

.append（错误）；
}
});
}
