class SiteTreeLinkTracking extends DataExtension (View source)

Adds tracking of links in any HTMLText fields which reference SiteTree or File items.

Attaching this to any DataObject will add four fields which contain all links to SiteTree and File items referenced in any HTMLText fields, and two booleans to indicate if there are any broken links. Call augmentSyncLinkTracking to update those fields with any changes to those fields.

Note that since both SiteTree and File are versioned, LinkTracking and FileTracking will only be enabled for the Stage record.

Note: To support HasBrokenLink for non-SiteTree classes, add a boolean HasBrokenLink field to your db config and this extension will ensure it's flagged appropriately.
