mysql_connect('localhost', 'root', '');
mysql_select_db('db_blog');
$q1 = "INSERT INTO product(member_id, product_name, category_id, product_Keyword, product_des, product_poto, product_brand, product_model, product_packaging, product_detdes, approv, c_date)
VALUES ('$txtMemberId','$txtproductName','$txtCategory','$txtproductKeyword','$txt summary','$images','$txtBrandName','$txtModel','$txtpackagingDesc','$txtDet ailDesc','0',now())";
echo $q1 ;
mysql_query($q1);
$productId = mysql_insert_id();

$q2 = "INSERT INTO products(product_id, member_id, rfq_type, currency, R_TypeStart, price_marking, str_date, str_time, ex_date, ex_time, R_AutoEx, delivery_date, pay_terms, delivery_to, ket, data_sheet)
