Upload script
Hej!Jeg har et simpelt upload script, som jeg ikke kan få til at gøre helt som jeg vil.
Således ser det ud:
<% @EnableSessionState = False %>
<% Option Explicit %>
<% Response.Expires = 0 %>
<%
Dim UPLOAD_PATH
UPLOAD_PATH = Server.MapPath("files")
Dim g_oFso, g_oFolder, g_oFile
Set g_oFso = Server.CreateObject("Scripting.FileSystemObject")
Set g_oFolder = g_oFso.getFolder(UPLOAD_PATH)
If (Request.ServerVariables("REQUEST_METHOD") = "POST") Then
Dim g_oUpload
Set g_oUpload = get_upload_files()
Dim fpos, fcontent
fcontent = g_oUpload("upload").Item("content")
Set g_oFile = g_oFso.CreateTextFile(UPLOAD_PATH & "\" & extract_filename(g_oUpload("upload").Item("filename")))
For fpos = 1 to LenB(fcontent)
g_oFile.Write chr(AscB(MidB(fcontent, fpos, 1)))
Next
g_oFile.Close: Set g_oFile = Nothing
Response.Redirect Request.ServerVariables("SCRIPT_NAME")
End If
Response.Write "<html><body><table>"
Response.Write "<tr><td><hr></td></tr>"
For Each g_oFile In g_oFolder.Files
Response.Write "<tr><td><a href=""files/" & g_oFile.Name & """>" & g_oFile.name & "</a></td></tr>"
Next
Response.Write "<tr><td><hr></td></tr>"
Response.Write "<tr><td align=""right""><form name=""frmUpload"" method=""post"" enctype=""multipart/form-data"" action=""" & Request.ServerVariables("SCRIPT_NAME") & """>"
Response.Write "<input type=""file"" name=""upload""> <input type=""submit"" value=""upload""></td></tr>"
Response.Write "</table></body></html>"

I stedet for at den, når man har uploadet en fil, viser filen man lige har uploadet, så skal der stå: "Billedet er blevet uploadet korrekt."
