Using Admin Items Form Tab

Are there any examples of plugins that use the admin_items_form_tabs filter to add a tab and form to items to save info linking an item to another resource? I can't seem to find any.


Two that might be useful comparison are Item Relations and Geolocation. They take different approaches, but some things in those might give you ideas

Item Relations might be exactly what you need. It creates the tab and generates the form for relating an item to an item. What's in the form and controller and the plugin's afterItemSave hook should give an in-depth example. It might even work for you out of the box.

Geolocation isn't as close to what you describe, but might be a helpful comparison for plugin-specific records being saved with relations to items. Again, the afterItemSave hook should be a helpful example.
