[SOLVED] How do you create a Sitecore pipeline processor that runs when a new item is upload to the Media Library

How do you create a Sitecore pipeline processor that runs when a new item is upload to the Media Library

I would like to build a Sitecore pipeline processor that would grab the ID of a media item when it is uploaded and save that ID to an existing custom database that is used by a third-party application.

I have been unable to locate any How-to or examples on how to do this?

I am using Sitecore 8.0 Update 5 and an MVC structure for my code.

Solution

You can check in the uiUpload pipeline, but that will not fire for programatically created items, i.e. it will only fire when a user uploads an item via the CMS interface.

Create a new processor class:

public class ExternalSystemProcessor
{
    public void Process(UploadArgs args)
    {
        foreach (Item file in args.UploadedItems.Where(file => file.Paths.IsMediaItem))
        {
            // Custom code here
            SaveToExternalSystem(file.ID);
        }
    }
}

And then patch the in after the default save processor:

<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/" xmlns:set="http://www.sitecore.net/xmlconfig/set/">
  <sitecore>
    <processors>
      <uiUpload>
        <processor type="MyProject.Custom.Pipelines.ExternalSystemProcessor, MyProject.Custom" mode="on"
                   patch:after="*[@type='Sitecore.Pipelines.Upload.Save, Sitecore.Kernel']" />
      </uiUpload>
    </processors>
  </sitecore>
</configuration>
