【问题描述】:
我的照片桌是
Column Name Data Type Constraint
PhotoID Int Primary key,auto increment
PhotoName Varchar(100)
ExtName Varchar(100)
PhotoType Varchar(100)
PhotoSize Int
TempleID Int Foreign key with templeinfo
插入过程是
create proc [dbo].[prcTemplePhoto]
(
@PhotoName Varchar(100),
@ExtName Varchar(100),
@PhotoType Varchar(100),
@PhotoSize int,
@TempleID Int
)
as
insert into TemplePhoto(PhotoName,ExtName,PhotoType,PhotoSize,TempleID) values (@PhotoName,@ExtName,@PhotoType,@PhotoSize,@TempleID)
select @@IDENTITY
我想一次上传多张照片,为此我从互联网上复制了代码
在设计方面
<tr>
<td>
<asp:Label ID="lbltemplepic" runat="server" Text="Temple Photo"></asp:Label>
</td>
<td id="fileUploadarea">
<div>
<div id="Div1">
<asp:FileUpload ID="templeupload" runat="server" CssClass="fileUpload" /><br />
</div>
<br />
<div>
<input style="display: block;" id="btnAddMoreFiles" type="button" value="Add more images" onclick="AddMoreImages();" /><br />
<asp:Button ID="btnuplaod" runat="server" Text="Upload" OnClick="btnuplaod_Click" />
</div>
</div>
</td>
<td></td>
</tr>
<tr><td></td><td>
<asp:Button ID="btninsert" runat="server" Text="Insert" OnClick="btninsert_Click" />
</td><td></td></tr>
<tr><td></td><td>
<asp:Label ID="lblerror" runat="server" Text=""></asp:Label></td><td></td></tr>
<script lang="javascript" type="text/javascript">
function AddMoreImages() {
if (!document.getElementById && !document.createElement)
return false;
var fileUploadarea = document.getElementById("fileUploadarea");
if (!fileUploadarea)
return false;
var newLine = document.createElement("br");
fileUploadarea.appendChild(newLine);
var newFile = document.createElement("input");
newFile.type = "file";
newFile.setAttribute("class", "fileUpload");
if (!AddMoreImages.lastAssignedId)
AddMoreImages.lastAssignedId = 100;
newFile.setAttribute("id", "FileUpload" + AddMoreImages.lastAssignedId);
newFile.setAttribute("name", "FileUpload" + AddMoreImages.lastAssignedId);
var div = document.createElement("div");
div.appendChild(newFile);
div.setAttribute("id", "div" + AddMoreImages.lastAssignedId);
fileUploadarea.appendChild(div);
AddMoreImages.lastAssignedId++;
}
</script>
在代码方面
if (templeupload.HasFile)
{
TemplePhoto tempphoto = new TemplePhoto();
tempphoto.PhotoName = templeupload.FileName;
tempphoto.PhotoSize = templeupload.PostedFile.ContentLength;
tempphoto.PhotoType = templeupload.PostedFile.ContentType;
tempphoto.ExtName = tempphoto.PhotoName.Substring(tempphoto.PhotoName.LastIndexOf(".") + 1);
tempphoto.TempleID = ans;
HttpFileCollection hfc = Request.Files;
for (int i = 0; i < hfc.Count; i++)
{
HttpPostedFile hpf = hfc[i];
if (hpf.ContentLength > 0)
{
int id = new DBTemplePhoto().InsertData(tempphoto);
if (id != 0)
{
hpf.SaveAs(Server.MapPath("~/templepics/") + ans.ToString() + "." + tempphoto.ExtName);
lblerror.Text = " File is Uploaded ";
}
else
{
lblerror.Text = "Please check all the fields";
}
}
}
但它只上传一张图片
实际上,我想要多个图像上传器,就像 gmail 一样,但我妥协了这个。 你能帮我解决上传多张图片的代码错误吗? 如果可能的话,请告诉代码以获取像 gmail 这样的上传器
【问题讨论】:
-
在我看来这可能是浏览器问题。你能告诉我你用的是什么浏览器吗?我知道IE10不支持多文件上传...
-
正在使用什么版本的 asp.net?你是在做 ctrl+selecting a file...来选择多个文件吗?
-
我正在使用 c# 4.0 和 Visual Studio 2012。是的,我想通过按 ctrl 来选择多张图片
