รบกวนดู code ให้หน่อยครับ คือ จากฟอร์มดังกล่าวผมส่งค่า <?=$supplier?> ไปด้วย เพื่อเรียกใช้งานอีก

<? 
  
  include "connect.php";
  
				$id=$_GET[id];
				
  				$sql= "select * from tb_product  where sup_id ='$id' ";
				$sqlquery=mysql_db_query($dbname,$sql);
				
				while($result= mysql_fetch_array($sqlquery)){
				
				if($bg == "#F8FAEF") { //ส่วนของการ สลับสี
				$bg = "#D2DDD2";
				} else {
				$bg = "#F8FAEF";
				}
				$id=$result['p_id'];
				$code=sprintf("P%04d",$id);
				$name=$result['p_name'];
				$name2=$result['p_name2'];
				$qty=$result['p_qty'];
				$cost=$result['p_cost'];
				$type=$result['p_type'];
				
				$sqltype= "select * from tb_type where t_id='$type' ";
					$sqlquerytype=mysql_db_query($dbname,$sqltype);
					$result4= mysql_fetch_array($sqlquerytype);
					$tname=$result4['t_name'];
				
								
				$detail=$result['p_detail'];
				$spechee=$result['p_spechee'];
				
				
				$sqlspechee= "select * from tb_spechee where s_id='$spechee' ";
					$sqlqueryspechee=mysql_db_query($dbname,$sqlspechee);
					$rs1= mysql_fetch_array($sqlqueryspechee);
					$specheename=$rs1['s_name'];
				
				
				$price=$result['p_price'];
				$qty=$result['p_qty'];
				$img=$result['p_images'];
				$size=$result['p_size'];
				$supplier=$result['sup_id'];
				
				$sqlsup= "select * from tb_supplier where sup_id='$supplier' ";
					$sqlquerysup=mysql_db_query($dbname,$sqlsup);
					$rs= mysql_fetch_array($sqlquerysup);
					$supname=$rs['sup_name'];
