How to get the item currently being published from publishing pipeline

Question

I am trying to build a custom publishing pipeline in SC 9.3 where I need to do some custom operations on the items being currently published.

I created a custom pipeline and the code looks like below:

public class MyProcessor : PublishItemProcessor
{
    public override void Process(PublishItemContext context)
    {
            if (context == null || context.Aborted)
            {
                return;
            }
            var item = Sitecore.Context.Item;
            Item sourceItem = context.PublishHelper.GetSourceItem(context.ItemId);
            Item targetItem = context.PublishHelper.GetTargetItem(context.ItemId);
            ...
    }
 }

Unfortunately, I ran out of ideas on how to get the currently published item ID inside this pipeline. In the code above the item is null, and the sourceItem and targetItem return the language of the content, not the actual item that I am publishing.

Could you please help and point me out to the best way how to check which item is being published?

You can achieve this by adding a handler to "publish:itemProcessed" event instead:

public void YourItemProcessed(object sender, EventArgs args)
{
    var itemProcessedEventArgs = args as ItemProcessedEventArgs;
    var context = itemProcessedEventArgs != null ? itemProcessedEventArgs.Context : null;

    if (context.Result.Operation.Equals(PublishOperation.None) ||
        context.Result.Operation.Equals(PublishOperation.Skipped))
    {
        return;
    }
    try
    {
        // Your logic here...
    }
    catch (Exception e)
    {
        Sitecore.Diagnostics.Log.Error($"Error at publish:itemProcessed. Item ID: {context.ItemId} Name: {context.ItemName} => {e.InnerException}", this);
    }
}

Then patch it:

<events>
    <event name="publish:itemProcessed">
      <handler type="Your.Project.YourItemProcrssed, Your.Project" method="YourItemProcessedLogic"/>
    </event>
</events>

I hope it helps you..

Actually context.PublishHelper.GetSourceItem and context.PublishHelper.GetTargetItem are the right methods to use.

What they do in the background, they take Options.Language and Options.SourceDatabase (or Options.TargetDatabase for target item) and call GetItem using those parameter together with item id.

When you select an item in Content Editor and choose some language version and click publish, you have an option to choose which languages will be published. And your processor should be executed for every language chosen in the options. It won't be executed on the version that you selected in Content Editor unless you choose that language in the options window.
