bootstrap fileinput+MVC 上传多文件,保存

新增用户资料,需要用户上传多笔附件,所以就尝试用了fileinput控件,显示效果如图:

首先,先在model中定义数据模型:

public partial class create
{
       [Required]
       [Display(Name = "附件")]
       public HttpPostedFileBase[] attach { get; set; }
} 

视图中定义控件:

<div class="form-group">
                @Html.LabelFor(m => m.attach, new { @class = "col-sm-3 control-label" })
                <div class="col-sm-7">
                    @Html.TextBoxFor(model => model.attach, new { type = "file", multiple = "multiple", accept = "application/msword,application/pdf,application/vnd.openxmlformats-officedocument.wordprocessingml.document" })
                    @Html.ValidationMessageFor(m => m.attach, "", new { @class = "text-danger" })
                </div>
            </div>

该控件的类型是multiple,可以选择多个文件;accept属性是可选择的文件类型,这里我们要去只能选择doc docx pdf ,需支持其他类型的可自行百度;ValidationMessageFor是必填

js中调用该控件:

var url = rootUrl + "attachment/upload";
$("#attach").fileinput({
    theme: "explorer", //主题  
    language: 'zh',
    uploadUrl: url,// 上传请求路径  
    allowedFileExtensions : ["pdf", "doc","docx"],//允许上传的文件后缀           
    showUpload: false,//是否显示上传按钮  
    showCaption: false,//是否显示容器  
    dropZoneEnabled: false,//是否显示拖拽区域   
    removeFromPreviewOnError: true,//是否移除校验文件失败的文件  
    layoutTemplates: {     
        actionUpload: '',   //取消上传按钮 
        actionZoom: ''      //取消放大镜按钮 
    },
    showPreview: true,      //显示预览     
    minFileCount: 1,   //最低文件数量  
    //maxFileCount: 3,   //最多文件数量  
    maxFileSize: 1024*2,  //允许文件上传大小  
    overwriteInitial: false,
    previewFileIcon: '<i class="fa fa-file"></i>',
    initialPreviewAsData: true, // defaults markup    
    preferIconicPreview: true, // 是否优先显示图标  false 即优先显示图片  
    previewFileIconSettings: { // configure your icon file extensions  
        'doc': '<i class="fa fa-file-word-o text-primary"></i>',
        'docx': '<i class="fa fa-file-word-o text-primary"></i>',
        'xls': '<i class="fa fa-file-excel-o text-success"></i>',
        'xlsx': '<i class="fa fa-file-excel-o text-success"></i>',
        'ppt': '<i class="fa fa-file-powerpoint-o text-danger"></i>',
        'pdf': '<i class="fa fa-file-pdf-o text-danger"></i>',
        'zip': '<i class="fa fa-file-archive-o text-muted"></i>',
        'htm': '<i class="fa fa-file-code-o text-info"></i>',
        'txt': '<i class="fa fa-file-text-o text-info"></i>',
        'mov': '<i class="fa fa-file-movie-o text-warning"></i>',
        'mp3': '<i class="fa fa-file-audio-o text-warning"></i>',
        'jpg': '<i class="fa fa-file-photo-o text-danger"></i>',
        'gif': '<i class="fa fa-file-photo-o text-muted"></i>',
        'png': '<i class="fa fa-file-photo-o text-primary"></i>'
    }
});

上传的url就是点击Upload按钮调用的方法,我们没有使用这个url,我们是在提交之后再上传的,所以可以忽略上传

页面提交保存后台:

        [HttpPost]
        [ValidateInput(false)]
        [ValidateAntiForgeryToken]
        [UIExceptionResult]
        public ActionResult attachment_create(create model)
        {
            if (ModelState.IsValid)
            {
               
                    string uploadPath = Server.MapPath(string.Format("~\\upload\\{0}\\", DateTime.Now.ToString("yyyyMMdd")));
                    string savePath = string.Format("/upload/{0}/", DateTime.Now.ToString("yyyyMMdd"));
                    if (Directory.Exists(uploadPath) == false)
                    {
                        Directory.CreateDirectory(uploadPath);
                    }
                    if (model.attch != null && model.attch.Count() > 0)
                    {
                        for (int i = 0; i < model.attch.Count(); i++)
                        {
                            var _file = model.attch[i];
                            string _imageName = DateTime.Now.Ticks.ToString() + System.IO.Path.GetExtension(_file.FileName);
                            var path = uploadPath + _imageName;
                            //保存
                            _file.SaveAs(path);
                        }

                    }
            return View(model);
        }
