    Very strange file upload behavior

    I tried to search for this issue on the group, but don't even know
    where to start, so here's my problem.

    We have a very simple form which has a file upload box.
    Upon submit the file should be uploaded (using the copy function, from
    the server's temp directory to our final directory), the database
    should be updated, and the user should be notified of success/failure.
    In that order. When we test it at the office, and even from a dial-up
    at home, everything is fine.

    When my client tries to do it from his cable modem connection here is
    what happens: He chooses the file on the form, clicks submit and the
    page churns away for a long while. Then, it just goes back to the form
    page. In the meantime, the file has been moved to the server's temp
    directory, but does not get to our final directory. The database gets
    updated (which should only happen after the copy function), but no
    confirmation message is given.

    Here is some truncated code:

    function upload_file()
    {
    global $target_dir,$ta rget_file;
    $upload_temp = $_FILES['filename_new']['tmp_name'];
    $upload_file = $_FILES['filename_new']['name'];
    $target_dir = "../downloads";
    $target_file = $target_dir . "/" . $upload_file;

    if (!copy($upload_ temp, $target_file))
    {
    echo "<h4>Failed to upload file...<h4><br> \n";
    die();
    }
    else
    {
    echo "<h4>Upload ed File Successfully... <h4><br>\n";
    return;
    }
    }
    upload_file();
    $sql = "INSERT INTO downloads
    (name,filename, sort_order,desc ription,categor y,registration) VALUES
    ('".$name."','" .$filename."'," .$sort_order
    ..",'".$desc."' ,".$category.", ".$registration .")";

    $result = mysql_db_query( $glb_db,$sql) or die(mysql_error ());

    print "<p>The download has been added";

    Use move_uploaded_f ile() instead.

      I'll give it a try right away. But can you help me understand the
      logic of why this is better?

        Read the documentation at
        http://de3.php.net/manual/en/functio...oaded-file.php.

        Their english is much better than mine. :-)
