    Use product data from Umbraco nodes

    I have a very basic shopping cart with only a few product to order some booklets and no need for payment providers in this case..

    Right now I have a setup in Website application i Visual Studio with database tables for products and orders - just using Northwind database, but I think I only need tables for Product, Order and OrderDetails.

    I have hightlighted to most important columns I need.

    What is the best approach to use productdata from nodes in Umbraco in a .NET usercontrol with product nodes from Umbraco?

    Can I update the Product table on publish and unpublish (or delete) to match the data in Umbraco?

    Hello,

    It might be good to start with this old topic: http://our.umbraco.org/forum/developers/extending-umbraco/10412-Store-webshop-products-as-nodes-or-in-a-custom-table

    If you want to use a custom table you can show the data with a UserControl or Razor. 

    If you want to manage your custom tables from Umbraco you might like this package: http://our.umbraco.org/projects/developer-tools/dewd

    Hi Jeroen

    I haven't use dewd before, but it seems the data are maintained in a custom section and setup with custom sql queries?

    I have the following structure in content section and I would like that the data are maintained from here.

    A few years back I had product data in the content stucture and was using the eventshandlers to add the data to a custom table something like this:

    using System;
    using System.Collections.Generic;
    using System.Text;
    using System.Data.SqlClient;
    using System.Web.Configuration;
    
    using umbraco.cms.businesslogic.web;
    using umbraco.BusinessLogic;
    using umbraco.presentation.nodeFactory;
    using umbraco.cms.businesslogic.media;
    
    namespace Events
    {
        public class ProduktData : ApplicationBase
        {   
    
            public ProduktData()
            {
                Document.AfterPublish += new Document.PublishEventHandler(Document_AfterPublish);
            }
    
    
            void Document_AfterPublish(Document sender, umbraco.cms.businesslogic.PublishEventArgs e)        
            {     
                // kun gældende for nodes der anvender Produkt dokument typen.
                if (sender.ContentType.Alias == "Produkt")
                {
    
                    // databaseforbindelse
                    string connectionString = WebConfigurationManager.ConnectionStrings["umbracoConnectionString"].ConnectionString;
                    SqlConnection conn = new SqlConnection(connectionString);
    
                    try
                    {
                        // opretter strenge med værdierne angivet til produktet
                        string Navn = sender.getProperty("name").Value.ToString();
                        string Varenr = sender.getProperty("varenr").Value.ToString();
                        string Pris = sender.getProperty("price").Value.ToString();
                        string Kategori = sender.getProperty("kategori").Value.ToString();
                        string Billede = sender.getProperty("imageURL").Value.ToString();
                        string Nyhed = sender.getProperty("news").Value.ToString();
                        string Beskrivelse = sender.getProperty("description").Value.ToString();
    
                        // finder node id'et, det konverteres til en integer
                        string nodeIDstring = umbraco.helper.Request("id");
                        Int32 nodeID = Convert.ToInt32(nodeIDstring);
    
                        // konverterer Billede tekststrengen til en int, opretter et Media objekt og
                        // opretter en streng, der sættes til værdien af datatypen med alias umbracoFile.
                        Int32 mediaID = Convert.ToInt32(Billede);
                        Media mymedia = new Media(mediaID);
                        string imageURL = mymedia.getProperty("umbracoFile").Value.ToString();
    
                        // parser værdien fra tekststrengen Nyhed til en int, der så konverteres til en boolean (True/False).
                        Int32 newsID = Int32.Parse(Nyhed);
                        bool news = Convert.ToBoolean(newsID);
    
                        // konverterer tekststrengen kategori til en int og derefter fåes den tilhørende tekst til id'et.
                        Int32 kategoriID = Convert.ToInt32(Kategori);
                        string category = umbraco.library.GetPreValueAsString(kategoriID);
    
    
                        // SQL-kommando - tjekker om BilledID'et eksisterer
                        // indsætter en række hvis BilledID'et ikke eksisterer ellers opdateres rækken.

                    }
                    catch (Exception ex)
                    {
                        Log.Add(LogTypes.Publish, sender.Id, ex.Message);
                    }
    
                    finally
                    {
                        // luk forbindelsen
                        conn.Close();
                    }
    
                }        
    
            }
        }
    }
    
    I guess there is a eventhandler for unpublish too, so the product table only contains data which you want to show on the website..
