PHP for function get POSTED values

PHP for function get POSTED values

I have this PHP/HTML Code:
<form method="post" action="create_quote2.php">
<table width="800" border="0" cellspacing="5" cellpadding="5">
<tr>
<td><strong>Select</strong></td>
<td><strong>Image</strong></td>
<td><strong>Name</strong></td>
<td><strong>Sale Price</strong></td>
<td><strong>Quantity</strong></td>
</tr>
<?php
$sql="SELECT * from products ";
$rs=mysql_query($sql,$conn) or die(mysql_error());
$counter=0;
while($result=mysql_fetch_array($rs))
{
$counter++;
echo '<input type="hidden" name="product'.$counter.'"
value="'.$_POST["checkbox$i"].'" />';
echo '<tr>
<td><input type="checkbox" value="'.$result["sequence"].'"
name="checkbox'.$counter.'" /></td>
<td>Image</td>
<td>'.$result["title"].'</td>
<td>&pound;'.$result["saleprice"].'</td>
<td><input type="text" name="qty" id="qty" size="20" /></td>
</tr>';
}
echo '<input type="hidden" name="counter" value="'.$counter.'" />';
?>
</table>
<input type="submit" name="submit" value="Next" />
</form>
so when boxes are checked you go to the next page with this code:
<table width="800" border="0" cellspacing="5" cellpadding="5">
<tr>
<td><strong>Image</strong></td>
<td><strong>Title</strong></td>
<td><strong>Sale Price</strong></td>
<td><strong>Trade Price</strong></td>
<td><strong>Quantity</strong></td>
<td><strong>Total Cost</strong></td>
</tr>
<?php
for($i=1; $i<=$_POST["counter"]; $i++)
{
if($_POST["checkbox$i"])
{
$counter++;
$sql="SELECT * from products where sequence = '".$i."' ";
$rs=mysql_query($sql,$conn) or die(mysql_error());
$result=mysql_fetch_array($rs);
echo '<tr>
<td>Image</td>
<td>'.$result["title"].'</td>
<td>&pound;'.$result["saleprice"].'</td>
<td>&pound;'.$result["tradeprice"].'</td>
<td>&nbsp;</td>
<td>&nbsp;</td>
</tr>';
}
}
?>
</table>
it works fine and selects all the correct products from the products table
but i need a way to get the posted quantity values for each row.
how can i display the posted quantity values on the second page?
P.S. im not worried about SQL injection on this code...
