    Multiple file Upload


    I am in need to upload multiple files.I am Using following asp code :

    SCompanyCode = Request.QueryString("SCompanyCode")

    Set upl = Server.CreateObject("SoftArtisans.FileUp")
    upl.Path = Server.Mappath("Clients\"&SCompanyCode)

    arrFile1 = split(upl.Form("file1"),"\")
    filename1 = trim(arrFile1(ubound(arrFile1)))

    arrFile2 = split(upl.Form("file2"),"\")
    filename2 = trim(arrFile2(ubound(arrFile2)))

    Response.write filename1
    Response.write filename2

    if upl.Form("file1").TotalBytes > 0 then
    upl.SaveAs filename1
    end if
    if upl.Form("file2").TotalBytes > 0 then
    upl.SaveAs filename2
    end if

    The error is it shows file names with .temp extension and it doesn't save the file.

    Can't guess what's the problem.

    Can any body master in multiple file upload help me :'(

    Hi, and welcome to the board!

    Here is a pure ASP (i.e. no components) resource for letting the user upload one or more files which is something that was unfortunately not built into ASP:

    I got this code from one site like that.I think it can help. Just do some simple modifications by looking more carefully and using more of your brains.

    <%@ Language=VBScript %>
    option explicit
    Response.Expires = -1
    Server.ScriptTimeout = 600
    <!-- #include file="aspupload.asp" -->

    ' ****************************************************
    ' Change the value of the variable below to the pathname
    ' of a directory with write permissions, for example "C:\Inetpub\wwwroot"
    Dim uploadsDirVar
    uploadsDirVar = "c:\inetpub\wwwroot\upload\"
    ' ****************************************************

    ' Note: this file uploadTester.asp is just an example to demonstrate
    ' the capabilities of the freeASPUpload.asp class. There are no plans
    ' to add any new features to uploadTester.asp itself. Feel free to add
    ' your own code. If you are building a content management system, you
    ' may also want to consider this script:

    function OutputForm()
    <form name="frmSend" method="POST" enctype="multipart/form-data" action="uploadTester.asp" onSubmit="return onSubmitForm();">
    <B>File names/B><br>
    File 1: <input name="attach1" type="file" size=35><br>
    File 2: <input name="attach2" type="file" size=35><br>
    File 3: <input name="attach3" type="file" size=35><br>
    File 4: <input name="attach4" type="file" size=35><br>
    <!-- These input elements are obviously optional and just included here for demonstration purposes -->
    <B>Additional fields (demo)/B><br>
    Enter a number: <input type="text" name="enter_a_number"><br>
    Checkbox values: <input type="checkbox" value="1" name="checkbox_values">-1 <input type="checkbox" value="2" name="checkbox_values">-2<br>
