【问题描述】：
那里有类似的帖子，但它们似乎并不代表我的情况。如果这是重新发布，请提前道歉。
我的看法是
@FileUpload.GetHtml(initialNumberOfFiles:1,allowMoreFilesToBeAdded:true,includeFormTag:true, uploadText: "Upload" )
@model IEnumerable<EpubsLibrary.Models.Partner>
@{ using (Html.BeginForm("Index","Epub"))
{
@Html.DropDownList("PartnerID", (IEnumerable<SelectListItem>)ViewBag.Partners, "None")
<input type="submit" value="send" id="pickPartner" hidden="hidden"/>
}
}
<script type="text/javascript">
$(".file-upload-buttons input").click(function () {
$("#pickPartner").click();
});
</script>
我的控制器是
[HttpPost]
public ActionResult Index(IEnumerable<HttpPostedFileBase> fileUpload, FormCollection collection)
{
int selectedPartner, count =0;
//int selectedPartner = int.Parse(collection["PartnerID"]);
if(!int.TryParse(collection["PartnerID"], out selectedPartner))
{
selectedPartner = 0;
ModelState.AddModelError("", "You must pick a publishing agency");
}
IList<Partner> p = r.ListPartners();
ViewBag.Partners = new SelectList(p.AsEnumerable(), "PartnerID", "Name", selectedPartner);
//make sure files were selected for upload
if (fileUpload != null)
{
for (int i = 0; i < fileUpload.Count(); i++)
{
//make sure every file selected != null
if (fileUpload.ElementAt(i) != null)
{
count++;
var file = fileUpload.ElementAt(i);
if (file.ContentLength > 0)
{
var fileName = Path.GetFileName(file.FileName);
// need to modify this for saving the files to the server
var path = Path.Combine(Server.MapPath("/App_Data/uploads"), Guid.NewGuid() + "-" + fileName);
file.SaveAs(path);
}
}
}
}
if (count == 0)
{
ModelState.AddModelError("", "You must upload at least one file!");
}
return View();
}
我正在使用 Microsoft Web Helpers 的文件上传助手上传文件。我遇到的问题是助手创建了一个表单，我还有另一个表单需要在同一页面上提交数据。
我想我可以链接提交按钮，这样当您点击上传时，它也会发送其他表单数据，但数据不会被发送。每个表格都独立工作，没有问题，但我需要他们一起工作。任何意见，将不胜感激。
好的，我用
更新了视图@model IEnumerable<EpubsLibrary.Models.Partner>
@{ using (Html.BeginForm("Index","Epub"))
{
@Html.DropDownList("PartnerID", (IEnumerable<SelectListItem>)ViewBag.Partners, "None")
@FileUpload.GetHtml(initialNumberOfFiles: 1, allowMoreFilesToBeAdded: true, includeFormTag: false, uploadText: "Upload")
<input type="submit" value="send" id="pickPartner"/>
}
}
但是现在文件数据似乎不再被传递了。
-- 更新--
我进行了以下更改。 视图现在看起来像
@model IEnumerable<EpubsLibrary.Models.Partner>
@{ using (Html.BeginForm("Index", "Epub", new { enctype = "multipart/form-data" }))
{
@Html.DropDownList("PartnerID", (IEnumerable<SelectListItem>)ViewBag.Partners, "None")
@FileUpload.GetHtml(initialNumberOfFiles: 1, allowMoreFilesToBeAdded: true, includeFormTag: false, uploadText: "Upload")
<input type="submit" value="send" id="pickPartner"/>
}
}
和控制器
[HttpPost]
public ActionResult Index(IEnumerable<HttpPostedFileBase> fileUpload, int PartnerID = 0)
//public ActionResult Index(IEnumerable<HttpPostedFileBase> fileUpload, FormCollection collection)
{
int count =0;
IList<Partner> p = r.ListPartners();
ViewBag.Partners = new SelectList(p.AsEnumerable(), "PartnerID", "Name", PartnerID);
//make sure files were selected for upload
if (fileUpload != null)
{
for (int i = 0; i < fileUpload.Count(); i++)
{
//make sure every file selected != null
if (fileUpload.ElementAt(i) != null)
{
count++;
var file = fileUpload.ElementAt(i);
if (file.ContentLength > 0)
{
var fileName = Path.GetFileName(file.FileName);
// need to modify this for saving the files to the server
var path = Path.Combine(Server.MapPath("/App_Data/uploads"), Guid.NewGuid() + "-" + fileName);
file.SaveAs(path);
}
}
}
}
if (count == 0)
{
ModelState.AddModelError("", "You must upload at least one file!");
}
return View();
}
}
我试图弄清楚文件数据是如何在帖子中发送的（如果是的话），以便我可以保存文件。
-- 最终更新答案--
问题原来是两个问题。第一个问题是@FileUpload 需要设置includeFormTag: false
我发现的另一个问题是我需要确保在我的 @Html.BeginForm 中包含 FormMethod.Post 这是在 fileUpload 计数一直返回为 0 时发现的。我在 firebug 上运行了探查器，它指出文件数据实际上并没有被发布。下面是更正后的代码。
我的看法
@model IEnumerable<EpubsLibrary.Models.Partner>
@{ using (Html.BeginForm("Index", "Epub", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
@Html.DropDownList("PartnerID", (IEnumerable<SelectListItem>)ViewBag.Partners, "None")
@FileUpload.GetHtml(initialNumberOfFiles: 1, allowMoreFilesToBeAdded: true, includeFormTag: false, uploadText: "Upload")
<input type="submit" value="send" id="pickPartner"/>
}
}
我的控制器
[HttpPost]
public ActionResult Index(IEnumerable<HttpPostedFileBase> fileUpload, int PartnerID = 0)
{
int count =0;
IList<Partner> p = r.ListPartners();
ViewBag.Partners = new SelectList(p.AsEnumerable(), "PartnerID", "Name", PartnerID);
//make sure files were selected for upload
if (fileUpload != null)
{
for (int i = 0; i < fileUpload.Count(); i++)
{
//make sure every file selected != null
if (fileUpload.ElementAt(i) != null)
{
count++;
var file = fileUpload.ElementAt(i);
if (file.ContentLength > 0)
{
var fileName = Path.GetFileName(file.FileName);
// need to modify this for saving the files to the server
var path = Path.Combine(Server.MapPath("/App_Data/uploads"), Guid.NewGuid() + "-" + fileName);
file.SaveAs(path);
}
}
}
}
if (count == 0)
{
ModelState.AddModelError("", "You must upload at least one file!");
}
return View();
}
感谢@Jay 和@Vasile Bujac 在这方面的帮助。
