请问各位高手一个PHP表格的问题?????

这是PHP主要的代码段:
<?php
//包含类文件
include("drawDataGrid.class.php");if (isset($_REQUEST['editTbl']))
{
        $editTbl = $_REQUEST['editTbl'];
}
else
{
        $editTbl=0;
}if (isset($_REQUEST['newTbl']))
{
        $newTbl = $_REQUEST['newTbl'];
}
else
{
        $newTbl=0;
}
if (isset($_REQUEST['rowNo']))
{
        $rowNo = $_REQUEST['rowNo'];
}
else
{
        $rowNo=0;
}if (isset($_REQUEST['curpage']))
   $curpage = $_REQUEST['curpage'];
else
   $curpage=0;if ($curpage == 0)
{
        $curpage = 1;
}
$db_conn=mysql_connect("localhost","root","123456");
mysql_select_db("php",$db_conn);
$query = "select * from logins";
$result=mysql_query($query,$db_conn);
$num_rows = mysql_num_rows($result);$rowLower = 0;
$rowUpper = $num_rows;
$colLower = 0;$fields = mysql_list_fields("php", "logins", $db_conn);
$columns = mysql_num_fields($fields);$colUpper = $columns + 2 ;$updateImg = true;
$deleteImg = false;

    现在能运行了,我在上面代码里面加入一个upload.php来实现一个上传文件的功能
    请问应该在上面代码的什么位置添加,还有要在哪些地主做相应的修改
    多谢了!!!!
