 1 require "database.php";

 3 $po_code = "YMWF2015-6-25-1";
 4 $customer = "youmei";
 5 $confirm_date = "2015-6-25";
 6 $delivery_date = "2015-7-25";

 8 $create_order_sql =  "INSERT INTO `ld_crm`.`order` (`id`, `po_code`, `customer`, `confirm_date`, `delivery_date`) VALUES (NULL, ‘$po_code‘, ‘$customer‘, ‘$confirm_date‘, ‘$delivery_date‘)";
//注意此处前面的`ld_crm`中并不是单引号而是esc下面那个按键的符号。后面的VALUES中的变量不能用双引号代替单引号，单引号前面不能有\转义字符

 9 10 11 if ($db_conn->query($create_order_sql) === TRUE) { 12 echo "New record created successfully"; 13 } else { 14 echo "Error: " . $create_order_sql . "<br>" . $db_conn->error; 15 }
