也有類似的帖子，但他們似乎並不代表我的情況。如果這是重新發布，請提前道歉。ASP.NET MVC3從同一頁發送多個表格
我有我的看法是
@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>
我控制器
[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();
}
我使用微軟的Web助手文件上傳助手上傳文件。我遇到的問題是助手創建了一個表單，並且我還需要在同一頁面上提交另一個表單以提交數據。
我想我可以鏈接提交按鈕，這樣當你點擊上傳時，它也發送了其他表單數據但數據沒有被髮送。每個表單都獨立於另一個而沒有問題，但我需要他們一起工作。任何意見，將不勝感激。
好的，我更新了
@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"/>
}
}
的看法，但現在該文件中的數據似乎並沒有被得到了通過。
- 更新 -
我做了以下更改。 視圖現在看起來像
@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
[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();
}
}
我試圖弄清楚如何將文件數據在後越來越送過來（如果是）控制器，所以我可以保存文件。
- 最後的更新與答案 -
好這個問題原來是兩倍.. 1問題與@FileUpload和需要設置includeFormTag: false
我發現的另一個問題是，我需要請確保在我的@Html.BeginForm包括FormMethod.Post這是在fileUpload計數保持爲0時發現的。我在螢火蟲上運行了分析器，並指出文件數據實際上沒有發佈。以下是更正後的代碼。
我看來
@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();
}
謝謝@Jay和@Vasile Bujac與此您的幫助。
請參閱上面的修改。現在我已經做了這個改變，文件數據似乎不再以同樣的方式通過了。謝謝。 – samack
這是在不發送FormCollection的情況下正確設置partnerID，但由於某種原因，即使我選擇多個文件，fileUpload.Count（）仍然爲0。 – samack
與Vasile建議一起，嘗試啓動Fiddler並查看您的文件發佈了哪些值。我會想象如果這些文件在工作之前，他們應該繼續工作。 – Jay
