While back I blogged about indexing blocks with EPiServer Search. Last week someone told me it might be useful to republish the pages containing the Block automatically when a Block is updated, so the search index will also be updated.
To do this, just add another event handler that responds to a Block being published.
public void Initialize(InitializationEngine context)
{
DataFactory.Instance.PublishingPage += this.OnPublishingPage;
DataFactory.Instance.PublishedContent += this.OnPublishedContent;
}
In the attached handler, get all references to the Block that was published, and (re)publish all pages that contain the Block.
public void OnPublishedContent(object sender, ContentEventArgs e)
{
// Check if the content that is published is indeed a block.
BlockData blockData = e.Content as BlockData;
// If it's not, don't do anything.
if (blockData == null)
{
return;
}
// Get the softlink repository.
ContentSoftLinkRepository linkRepository = ServiceLocator.Current.GetInstance<ContentSoftLinkRepository>();
// Get the references to this block
List<ContentReference> referencingContentLinks = linkRepository.Load(e.ContentLink, true).Where(link =>
link.SoftLinkType == ReferenceType.PageLinkReference &&
!ContentReference.IsNullOrEmpty(link.OwnerContentLink))
.Select(link => link.OwnerContentLink)
.ToList();
// Loop through each reference
foreach (ContentReference referencingContentLink in referencingContentLinks)
{
StandardPage parent;
DataFactory.Instance.TryGet(referencingContentLink, out parent);
// If it is not a standard page, do nothing
if (parent == null)
{
continue;
}
// Check if the containing page is published.
if (!parent.IsPendingPublish)
{
// Republish the containing page.
DataFactory.Instance.Save(parent.CreateWritableClone(), EPiServer.DataAccess.SaveAction.Publish);
}
}
}
Don’t forget to remove the handler when uninitializing.
public void Uninitialize(InitializationEngine context)
{
DataFactory.Instance.PublishingPage -= this.OnPublishingPage;
DataFactory.Instance.PublishedContent -= this.OnPublishedContent;
}
The rest of the code can stay the same.
Hope this helps.
