Question

How come a file being uploaded using Louis Motens' COM-Less software ASP solutions uploads an empty file?

Asked by: pborregg

This question references: <b>How to upload a document, store its name and properties in a database, using ASP Classic with VB and do it for free!</b> and is a continuation....

I've used the solution referenced here: http://www.planetsourcecode.com/vb/scripts/ShowCode.asp?txtCodeId=8525&lngWId=4

But the problem is: when the file is uploaded it uploads EMPTY!!! Meaning, the name of the file is put on the server, but the contents of the file are missing and when you open it, there's nothing there.

Here's the modified code I've written:

<%@LANGUAGE="VBSCRIPT" CODEPAGE="65001"%>

<%
'THIS WRITES TO THE DATABASE

Dim objUpload
Dim strFileName, strID, strPID, strDocCat, strDesc, strDocLoc, strDisp, strDateAdded, strBytes
Dim objConn
Dim objRs
Dim lngFileID

' Instantiate Upload Class
Set objUpload = New clsUpload

' Grab the form fields
strID = objUpload.Fields("ID").value
strPID = objUpload.Fields("PID").value
strFileName = objUpload.Fields("doc_name").value
strDocCat = objUpload.Fields("doc_category").value
strDesc = objUpload.Fields("description").value
strDocLoc = objUpload.Fields("DocLoc").value
strDisp = objUpload.Fields("display").value
strDateAdded = objUpload.Fields("date_added").value

'Response.Write(strID)
'Response.Write(strPID)
'Response.Write(strFileName)
'Response.Write(strDocCat)
'Response.Write(strDesc)
'Response.Write(strDocLoc)
'Response.Write(strDisp)
'Response.Write(strDateAdded)

Set objConn = Server.CreateObject("ADODB.Connection")
Set objRs = Server.CreateObject("ADODB.Recordset")

' Sometimes I personally have errors with one method on different servers, but the other works.
'objConn.Open "DRIVER=Microsoft Access Driver (*.mdb);DBQ=" & Server.MapPath("Files.mdb")
'objConn.Open "PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source=" & Server.MapPath("Files.mdb")
'ACCESS
'objConn.Open "PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source=F:\\0\\1\\131\\30\\1620682\\user\\1746753\\htdocs\\db\\dbname.db;UID=userid;PWD=password;Persist Security Info=False"

objRs.Open "documents", objConn, 3, 3

objRs.AddNew

objRs.Fields("ID").Value = strID
objRs.Fields("PID").Value = strPID
objRs.Fields("doc_name").Value = strFileName
objRs.Fields("doc_category").Value = strDocCat
objRs.Fields("doc_description").Value = strDesc
objRs.Fields("doc_location").Value = strDocLoc
objRs.Fields("active").Value = strDisp
objRs.Fields("date_added").Value = strDateAdded

objRs.Update
objRs.Close
lngFileID = strID
%>
<%
'THIS WRITES TO THE FILE SYSTEM!
Dim strPath

' Grab the file name
' strFileName = objUpload.Fields("doc_name").FileName

' Compile path to save file to
' strPath = Server.MapPath("Uploads") & "\" & strFileName
strPath = "F:\0\1\131\30\1620682\user\1746753\htdocs\webproject\content" & "\" & strFileName

'Response.Write(strPath)

' Save the binary data to the file system
objUpload("doc_name").SaveAs strPath

' Release upload object from memory
Set objRs = Nothing
Set objConn = Nothing
Set objUpload = Nothing
%>

<tr>
<td align="center"><input name="goBack" type="button" class="small" onclick="location.href='list-subproject-items.asp?pid=<%= Session("SV_PID") %>'" value="Return to Project Detail" /></td>
</tr>
</table>

<p> </p>
</body>
</html>

It all works fine, again, except the file contents are NOT uploaded with the file name. It's empty and all that's there is a 1K file with a name and nothing in the file itself.

Thanks.

Because the form you are submitting is not enctype="multipart/form-data"

by: pborreggPosted on 2008-12-03 at 16:54:35ID: 23091855

Ok, perhaps I didn't make myself clear. This page you see in the example, writes to the database and then writes the file to the file system. Below is the actual form:

<%@LANGUAGE="JAVASCRIPT" CODEPAGE="65001"%>
<%
//TRAP the session ID and make sure nobody can copy and paste as FAVORITE
//Go to bottom of page and take back to Login Screen.
var SESSID = Request.QueryString("SESSID");
//Response.Write("SESSIONID:: " + SESSID);
//Response.Write(Session.SessionID);
if (SESSID = Session("SID"))
{
%>

<%
var documents__MM_ID = "1";
if (String(Request.QueryString("ID")) != "undefined" &&
String(Request.QueryString("ID")) != "") {
documents__MM_ID = String(Request.QueryString("ID"));
}
%>
<%
var documents_cmd = Server.CreateObject ("ADODB.Command");
documents_cmd.ActiveConnection = MM_WebProject_STRING;
documents_cmd.CommandText = "SELECT * FROM documents WHERE id = ?";
documents_cmd.Prepared = true;
documents_cmd.Parameters.Append(documents_cmd.CreateParameter("param1", 5, 1, -1, documents__MM_ID)); // adDouble

var documents = documents_cmd.Execute();
var documents_numRows = 0;
%>
<%
var MaxDocVal__MM_PID = "AEPortal2007";
if (String(Request.QueryString("PID")) != "undefined" &&
String(Request.QueryString("PID")) != "") {
MaxDocVal__MM_PID = String(Request.QueryString("PID"));
}
%>
<%
var MaxDocVal_cmd = Server.CreateObject ("ADODB.Command");
MaxDocVal_cmd.ActiveConnection = MM_WebProject_STRING;
MaxDocVal_cmd.CommandText = "SELECT MAX(id) as Expr1000 FROM documents WHERE PID = ?";
MaxDocVal_cmd.Prepared = true;
MaxDocVal_cmd.Parameters.Append(MaxDocVal_cmd.CreateParameter("param1", 200, 1, 255, MaxDocVal__MM_PID)); // adVarChar

var MaxDocVal = MaxDocVal_cmd.Execute();
var MaxDocVal_numRows = 0;
%><%
var docCategory_cmd = Server.CreateObject ("ADODB.Command");
docCategory_cmd.ActiveConnection = MM_WebProject_STRING;
docCategory_cmd.CommandText = "SELECT * FROM document_categories";
docCategory_cmd.Prepared = true;

var docCategory = docCategory_cmd.Execute();
var docCategory_numRows = 0;

As you can see, the ENC-TYPE is already what you suggested. So I'm back to square one. The form action goes to the ToDatabase.asp page, the first code snippet here. So, it's something with the previous code snippet or the server on Network Solutions that's not allowing the content of the file to be uploaded. Your thoughts...???

Thanks, peter

Are you including all the classes? I think his upload script requires two files.

Have actually tried uploading in a simpler version of the code you have here? If you can't get it to work in a simple prototype stage, then debugging more code for no reason is not needed.

If you setup a form and a separate processing page, and then write the file to disk or output it to the screen do you see it?

Before you can add anything into the database you need to make sure your file exists by making sure the length of the field is greater than zero.

I also noticed you specify docloc as the client side file name. Is this your intent by design? Do you really want to save the document location as the client side location? Where do you store the string of the server directory in which the file is in?

Before wasting your own time even more, please do a sample upload script to see if your provider is giving you the ability to upload. Make sure your target upload directory has ALL write permissions for your user, or for all users.

<b>Yes, I'm including all the files. The first snippet is the Processing script and the second snippet is the "FORM" page.</b>

Have actually tried uploading in a simpler version of the code you have here? If you can't get it to work in a simple prototype stage, then debugging more code for no reason is not needed. <b>Yes, the simple example works locally but not on the server... I've tried it locally and on the net and the local version is all that works."</b>

If you setup a form and a separate processing page, and then write the file to disk or output it to the screen do you see it? <b>Yes</b>

Before you can add anything into the database you need to make sure your file exists by making sure the length of the field is greater than zero. <b>I'm not doing that... good suggestion....</b>

I also noticed you specify docloc as the client side file name. Is this your intent by design? <b>Yes</b> Do you really want to save the document location as the client side location? <b>The SERVER side location is being saved, not the client side. I've already taken care of this...</b> Where do you store the string of the server directory in which the file is in? <b>DocLoc field which is hidden...</b>

Before wasting your own time even more, please do a sample upload script to see if your provider is giving you the ability to upload. Make sure your target upload directory has ALL write permissions for your user, or for all users. <b> All write permissions have been granted....</b>

by: dankhasisPosted on 2008-12-03 at 19:15:07ID: 23092408

After granting write permissions, it still doesn't work in a simplified model?

by: pborreggPosted on 2008-12-03 at 19:16:07ID: 23092413

Oh, I forgot... the first code snippet is the (SECOND or PROCESSING page) and the Second code snippet is the form. What I did was take ToFileSystem.asp and ToDatabase.asp and combined them into the ToDatabase.asp (the FIRST CODE SNIPPET). Again, everything works except the content of the file is not being uploaded.

by: pborreggPosted on 2008-12-04 at 08:15:27ID: 23096625

No.... it doesn't.
