Today we show you how to use asp's upload capability to upload local files to the server.
The minimalist system consists of the following three files:
upload. htm-Upload port file, select local file
uploadimg. asp-Upload program control file
upload_5xsoft. inc--No component upload class, this file beginners do not need to learn, as long as you can use it
upload. htm Content-Upload port file, select local file
<html>
<head>
</head>
<body>
<table width="80%" border="0" align="center">
<form name="form1" method="post" action="uploadimg.asp" enctype="multipart/form-data">
<tr>
<td align="center"><input name="upfile" type="file" id="upfile"></td>
</tr>
<tr>
<td align="center"><input type="submit" name="Submit" value=" Upload pictures "></td>
</tr>
</form>
</table>
</body>
</html>
uploadimg. asp Content-Upload Program Control File
<!--#include FILE="upload_5xsoft.inc"-->
<%
dim upload,file,filepath
filepath="UPLOAD/"
set upload=new upload_5xSoft '' Create Upload Object
for each formName in upload.file '' List all uploaded files
set file=upload.file(formName) '' Generate 1 File objects
if file.FileSize>0 then '' If FileSize > 0 Explain that there is file data
fname = file.filename
file.SaveAs Server.mappath(filepath&fname) '' Save a file
end if
set file=nothing
next
set upload=nothing '' Delete this object
