Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

    rename file after uploading it

    I am having problems renaming a file after uploading it.
    I currently have:
    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
    <html>
    <%a5
    dim msg as c = ""
    if eval_valid("cmd")
    file.from_blob(ServerSetting.Document_Root + "\\" + FileToUpload.filename, FileToUpload.data)
    msg = "<a href=\"/" + FileToUpload.filename + "\" target=\"_blank\">" + FileToUpload.filename + "</a> was uploaded<br /><br />"
    msg = msg + crlf()+"file renamed to jat_test_091909.jpg"
    end if
    if eval_valid("cmd")
    file.rename(FileToUpload.filename,"jat_test_091909.jpg")
    end if
    %>

    <head>
    <title>File Upload example</title>
    </head>
    <body bgcolor="#ffffff">
    <form action=" <%a5 ? request.script_name %> " method="POST" enctype="multipart/form-data">
    <input type="file" name="FileToUpload" value="" size="50"><br />
    <input type="submit" name="cmd" value="Upload File">
    </form>
    <br>
    <br>

    <%a5 ? msg %>
    </body>
    </html>
    with the new file name hardcoded (to be later replaced by an account name).
    When I try and run this, I get:
    500 Internal Server Error
    "Script Error
    Error:Script: /image_map/upload_file.a5w line:11
    file.rename(FileToUpload.filename,"jat_test_091909.jpg")
    The system cannot find the file specified.
    C:\A5Webroot\image_map\jat_test_091909.jpg"
    What am I doing wrong?
    Any help would be appreciated.
    Thanks,

    Re: rename file after uploading it

    Jay, if possible, it's easier to rename the file before you save it instead of after.

    This isn't exactly your case, but it may help. In this script, I'm uploading 6 photos for a real estate listing, and I'm renaming them with the listing id and a number from 1 to 6, then saving the path and name in an Image File Reference field.

    Code:
     
Dim vMsg1 as C = "Upload Property Photos. Photos must be jpg type, not more than 600 pixels wide or 450 pixels high."
vFilename=alltrim(session.listing_id)+"."+alltrim(session.which)+".jpg"
if eval_valid("cmd")
    file.from_blob("[PathAlias.Photos]"+chr(92)+vFilename, FileToUpload.data)
 fn="[PathAlias.Photos]"+chr(92)+vFilename
    vMsg1 = "Photo "+FileToUpload.filename+" was uploaded as "+vFilename+"."
 tbl=table.open("[PathAlias.ADB_Path]\listings.dbf")
 indx=tbl.index_primary_put("listing_id")
 vRecNo=tbl.fetch_find(session.listing_id)
 if vRecNo>0 'was found
  tbl.change_begin()
  select
      case session.Which="1"
   tbl.Photo1=fn
      case session.Which="2"
   tbl.Photo2=fn
      case session.Which="3"
   tbl.Photo3=fn
      case session.Which="4"
   tbl.Photo4=fn
      case session.Which="5"
   tbl.Photo5=fn
      case session.Which="6"
   tbl.Photo6=fn
  end select
  tbl.change_end()
 end if
 tbl.close()
end if

      Re: rename file after uploading it

      Pat,
      Thanks so much for the suggestion.
      How would you handle this if all of the files were not getting uploaded at once? In your case, for example, (and I know this would probably not happen in a real estate listing, but for the sake of discussion) if one or two photos were already uploaded and the Realtor wanted to upload three more, how would you know if there were already two files on the server?
      Thanks.

        Re: rename file after uploading it

        Assuming you want to retain each file uploaded a unique filename could be generated.

        You need to consider the number of simultaneous users, number of files, file size etc.

        Some possible options are

        #1 - include a sequential number as part of filename and use the filefind.get function or similar to determine the next number t allocate from those already uploaded to the upload directory. The filename can also include the userid to identify who uploaded a particular file.

        #2 - add a record to a database table each time a file is uploaded and use an autoincrement type field witin table to determine filename.

        #3 - generate a filename that includes userid upload date time etc. The time precision would need to be decided to prevent possible conflicts.
