我想在我的wordpress页面添加滑块。我无法添加它。这是我的代码

Question

private void Order()
        {
            using (SqlConnection connection = new SqlConnection(connectionString1))
            {
                String query = "INSERT INTO Tbl_order (OrderName,Quantity,Price,Serves_way,Date,CustomerNo) VALUES (@OrderName,@Quantity, @Price,'" + servers + "','" + time1.ToString(format1) + "','" + Globals.order + "' )";
                Globals.order++;
                connection.Open();
                using (SqlCommand command = new SqlCommand(query, connection))
                {
                    // Add the length of this text column as third parameter...
                    command.Parameters.Add("OrderName", SqlDbType.NVarChar, 50);
                    command.Parameters.Add("Quantity", SqlDbType.Int);
                    command.Parameters.Add("Price", SqlDbType.Money);
                    command.Prepare();

                for (int i = 0; i < lst_OrderName.Items.Count; i++)
                {
                    command.Parameters[0].Value = lst_OrderName.GetItemText(lst_OrderName.Items[i]);
                    command.Parameters[1].Value = Convert.ToInt32(lst_QTY.Items[i]);
                    command.Parameters[2].Value = Convert.ToDouble(lst_Price2.Items[i]);

                    command.ExecuteNonQuery();

                    /* int totalRows = CustomerNo.Rows.Count;
                       int totalCols = CustomerNo.Columns.Count;

                       string value = CustomerNo.Rows[totalRows - 1][totalCols - 1].ToString();*/
                }
            }
        }
    }

有人可以解释我错在哪里吗？ 我想在页面中添加滑块。我用过短码操作符。上面的代码来自我的custompost文件。我检查了所有的css和js是否正确加载。但仍然无法获得输出。有人能帮我吗。提前致谢
