สอบถามเรื่องการใช้คำสั่ง move_uploaded_file และการอัพโหลดไฟล์ลง db ของโฮสจริง

if((move_uploaded_file($_FILES["filePO"]["tmp_name"],"myfile/".$_FILES["filePO"]["name"])&&(move_uploaded_file($_FILES["filePP"]["tmp_name"],"myfile/".$_FILES["filePP"]["name"]))))
	{
        $sql_in = " insert into datamain (job_no,supname , sup_tax, address, tel, email_sup , b_invoice , b_po , b_pp , invoice_no , po_no , pp_no , att_name , email_att , date_in , date_delivery, desciption  , price_unit ,quantity, a_price , weight , packaging ,  total_price , total_weight ,active) values ('$job','$supname', '$suptax ', '$address', '$tel' ,'$email_sup', '".$_FILES["fileIN"]["name"]."' , '".$_FILES["filePO"]["name"]."' , '".$_FILES["filePP"]["name"]."', '$invoice' , '$po' , '$pp' ,'$att_n' , '$email_att' , NOW(), '$date_del', '$des', '$p_u','$qty',  '$a_p', '$weight','$pack','$total_p','$total_w', 'wait') ";
	    $sql_q = mysql_query($sql_in);
echo "<script language=\"javascript\" type=\"text/javascript\"> alert('Complete') </script>";
