Sitecore Content Hub and code changes

Sitecore Hub It’s gaining territory among clients, and more and more will start use this tool soon.

New technologies, will bring some additional changes to our application. So Let’s explore and little bit.

First

If you don’t have the connector installed on your local, It’s a good opportunity to install

Download the following connector version: https://sitecoredev.azureedge.net/~/media/7F118478CF78478087A1DB3EBDF9FBFE.ashx?date=20190626T140600

Download the following instructions document: https://sitecoredev.azureedge.net/~/media/7CDD5336845E43A983310AA4E2D24F2C.ashx?date=20210302T090834

Browse Buttons

You will notice that all the Image Field will show a new button called “Browse Sitecore DAM”, this will enable the possibility of selecting an image

Before explore the “Browse Sitecore DAM”, let’s understand how Sitecore is storing the value for this Photo

Switch to “Raw values” and you will see the following

<image mediaid="{8DFB5795-B0B8-4825-98E5-0DB8D6B24BD5}" />

This tells us that Sitecore is Basically storing a reference to a Sitecore Item .

Authentication Step

Sitecore DAM requires authentication, it will ask for your credentials, so be ready to provide.

Now Let’s Select an image from Sitecore DAM, and after that, check the raw values again

Save the item and publish

<image alt="1639434665" mediaid="" stylelabs-content-id="100554" thumbnailsrc="https://mss-p-052.stylelabs.cloud/api/gateway/150354/thumbnail" src="https://mss-p-052-delivery.stylelabs.cloud/api/public/content/a605550148854ea39b23f6998c1c3fd4?v=cba2fe82" stylelabs-content-type="Image" height="160" width="124" />

Save the item

You can see that Sitecore DAM will store in a different way, and this will probably impact your application.

Now go to your webPage, and check if the image renders, Depending how the code is was written the image may not show up.

Using GlassMapper

If you have GlassMapper in your project, you can take advantage of this library

Ex The following implementation will rely on will use the “GlassMapper Image Field” in order to map the Field, and this is all that you need

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using Glass.Mapper.Sc.Fields;
namespace Feature.PageContent.Models
{
    public class HeaderModel
    {
        public Image Logo { get; set; } 
    }
}

After mapping the object , you can simple extract the image URL using the follow command, Ex:

var imageUrl = headerItem.Logo.Src;

You can also adapt your code to guarantee the compatibility with Media Library and also with Sitecore DAM, you can do this implementing checks and alternating between a simple “GetMediaUrl” and .Src provided by GlassMapper

Now check your Page and double check the image SRC, It should be loading the image from Sitecore Content Hub

In case you don’t have Glass installed on your solution, but still wanna take advantage of Content Hub

You can extract the string using Regex for instance

ImageField imgField = ((ImageField)item.Fields["photo"]);

var damImageUrl = Regex.Match(imgField.Value, "<img.+?src=[\"'](.+?)[\"'].+?>", RegexOptions.IgnoreCase).Groups[1].Value;

the end result will be the variable damImageUrl with the image path .

in this case I also would recommend to make this code compatible with a normal Sitecore Image Item, we would need to add a “if statement” checking MediaItem exist or not, and then , extract the Media Url using Media Manager ex : MediaManager.GetMediaUrl(imgField.MediaItem);

Good Luck!
