Insert *whatever* every nth row in Views I am looking for a solution to insert "something" every nth row in a view.  Technically, that "something" will be an Ad, but in Drupal terms it could be a block, a node, an entity, custom html row...really anything that can point me in the right direction.
In under Theme: Information you'll find Style output: views-view-table.tpl.php .... Override that. I selected the Theming info as opposed to other template overrides available because that is the one that has a foreach for rows. In your override you can add a counter to the foreach() along with an if($counter%10 == 0) { ... } with some markup or call to a block or something like that.
