I'm using Simplenews Scheduler to automatically send a digest of new nodes, by inserting a views token into Body field of the newsletter.
I need to prevent sending the newsletter if the View in question is empty (triggers No results).
Simplenews Scheduler allows for PHP evaluation (see at the bottom of the screenshot):
What do I need to enter there to ensure no new newsletter is created and sent if a certain view (with certain exposed filter or contextual filters options) has no results?
I believe this will do:
!empty(views_get_view_result('your_views_machine_name','your_display_id'));
If you need to pass arguments, you can pass them as individual strings after the display id. See the API documentation. I'm not sure if you can pass exposed filter arguments, though (the above would work fine for contextual filter arguments).
[view:my_views_machine_name=page_3=$arg1/IL+TX] Should my code then be !empty(views_get_view_result('my_views_machine_name','page_3','Category-1','IL+TX')); ?
display_id are passed to the view the same way Contextual Filters are passed through the path of the view. Thus, IF your view works fine (and produces the desired results) by calling it through its path as in www.example.com/view_path/Category-1/IL+TX then it should work by using views_get_view_result() with CAtegory-1 and IL+TX as the 3rd and 4th arguments.
