assets_delete_folder
This hook is called right before deleting a folder in Assets.
Hook Parameters
$folder_row
An StdClass object, representing the folder row that is about to get delete.
Notes
When deleting a folder, it's files are deleted first (each triggering a call to assets_delete_file
hook) and then it's subfolders are deleted (triggering assets_delete_folder
recursively) and only then is this hook called. That means that, when this hook is called, the folder in question is already empty of any files and subfolders.
