พอดีผมทำ...file upload แบบหลายช่องนะครับแต่ไม่ทราบว่าทำไมมันบันทึก ชื่อ file เป็น Array ครับ

<form action="saveaedit_store.php?cat_id=<?=$_GET["cat_id"];?>" name="frmEdit" method="post" enctype="multipart/form-data">
<?php
include_once 'config/connectnomal.php';
$strSQL = "SELECT * FROM page_store WHERE page_cInvCCode = '".$_GET["cat_id"]."' ";
$objQuery = mssql_query($strSQL);
$objResult = mssql_fetch_array($objQuery);
if(!$objResult)
{
	echo "Code=".$_GET["cat_id"];
}
else
{
?>
    <table width="600" border="1">
  <tr>
                <input type="text" name="txtpd_cod" size="5" value="<?=$objResult["page_cInvCCode"];?>"><br>
                <input type="file" name="fileUpload1"><br>
		<input type="file" name="fileUpload2"><br>
		<input type="file" name="fileUpload3"><br>
		<input type="file" name="fileUpload4"><br>
		<input name="hdnLine" type="hidden" value="4">
		<input name="btnSubmit" type="submit" value="Submit">
  </tr>
  </table>
  <?
  }
  mssql_close($objConnect);
  ?>
  </form>

<?
for($i=1;$i<=(int)($_POST["hdnLine"]);$i++)
		{
			if($_FILES["fileUpload".$i]["name"] != "")
			{
				if(move_uploaded_file($_FILES["fileUpload".$i]["tmp_name"],"images/".$_FILES["fileUpload".$i]["name"]))
				{
	include 'config/connectnomal.php';
	$strSQL = "UPDATE page_store SET ";
	$strSQL .="page_cInvCCode = '".$_POST["txtpd_cod"]."' ";
	$strSQL .=",banner_primary = '".$_FILES["fileUpload1"]."' ";
        $strSQL .=",banner_secondary = '".$_FILES["fileUpload2"]."' ";
        $strSQL .=",banner_tertiary = '".$_FILES["fileUpload3"]."' ";
        $strSQL .=",eyewear_hero = '".$_FILES["fileUpload4"]."' ";
	$strSQL .="WHERE page_cInvCCode = '".$_GET["cat_id"]."' ";
	$objQuery = mssql_query($strSQL);
                                }
                        }
                }
	if($objQuery)
	{
		echo "<center>Save Done.</center>";
	}
	else
	{
		echo "<center>Error Save [".$strSQL."]</center>";
	}
?>
