今天我們講解如何利用asp的上傳功能將本地的檔案上傳到伺服器上。
最簡系統包括下面三個檔案：
upload.htm --上傳口檔案，選擇本地檔案
uploadimg.asp --上傳程式控制檔案
upload_5xsoft.inc --無組件上傳類，此檔案初學者不用學習，只要會用就可以了
upload.htm內容————上傳口檔案，選擇本地檔案
<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="上傳圖片"></td> </tr> </form></table></body></html>
uploadimg.asp內容————上傳程式控制檔案
<!--#include FILE="upload_5xsoft.inc"--><%dim upload,file,filepathfilepath="UPLOAD/"set upload=new upload_5xSoft ''建立上傳對象for each formName in upload.file ''列出所有上傳了的檔案 set file=upload.file(formName) ''產生一個檔案對象 if file.FileSize>0 then ''如果 FileSize > 0 說明有檔案資料 fname = file.filename file.SaveAs Server.mappath(filepath&fname) ''儲存檔案 end ifset file=nothingnextset upload=nothing ''刪除此對象
upload_5xsoft.inc內容————此檔案內容不屬於本演練程式內容，本演練應用此類的方法
