Form values posting problem through PHP

[raj_2006]

Hi All,

I am giving the code here.There is currently four fields.And those four fields is under a while loop and will be generated more if there is more than one record Mysql Db.I have separated the field names by setting the fieldname.oid.oid is the unique id

Code:
//fetching the form values:
foreach($_POST as $k => $v)
{
echo "$k: $v<br />\n";
}
$sql="select * from ord_details where ord_val='$csesid'";
$q=mysql_query($sql) or die(mysql_error());
$tot=mysql_num_rows($q);
while($row=mysql_fetch_array($q))
{
$oid=$row['oid'];
//echo "update ord_details set desexed='$desexed',vac='$vac',mcno='$mcno',acquire='$acquire',condition='$condition',treat='$treat' where oid='$oid'";
//echo "update ord_details set treat='$treat' where oid='$oid'";
}

<form name="f" method="post" action="">
<?
//FETCHING THE VALUES FROM ORD_DETAILS TABLE
$s="select * from ord_details where ord_val='$csesid'";
$q_d=mysql_query($s) or die(mysql_error());
while($row=mysql_fetch_array($q_d))
{
$oid=$row['oid'];
$pet_name=$row['pet_name'];
$pet_species=$row['pet_species'];
$pet_breed=$row['pet_breed'];
$coverage=$row['coverage'];
$benefit=$row['benefit'];
$ref_code=$row['ref_code'];
$age=$row['age'];
$tfcost=$row['tfcost'];
$tmcost=$row['tmcost'];
$tacost=$row['tacost'];
?>

</table>
<? } ?>
<input type="submit" name="continue4" value="Continue" class="button">
<input type="hidden" name="oid" value="<?=id.$oid;?>" class="button">

</form>

Say there is total 2 records whose oid is 34 and 35.Now i want to fetch the form values first and then update the mysql db with the form values according to the oid i have got.But how can i separate the form values or separate oid.

Any suggestions plz.........thanks....Raj
