Views Eposed filter - proximity search, include content without a postal code

Question

I have a proximity search set up using gmap location by postal code. Using Drupal 7/Views 3. The exposed filter allows the user to filter by (taxonomy)type and/or postal code.

This is what I need to Do: Include some content that will not have a postal code in all results. I already set up a view of this content (without postal code) to display as no results behavior. but I would like to include this same content in all searches. How do I do this?

Answer 1

If you can not do it with the 'And/Or' option on the filters (accessed by clicking the little arrow next to the filters in the views ui). This is the best option.

Or you could use hook_views_query_alter to add something like "or where postcode = '' ".
I can not really go into detail of adding to the query as I dont know the structure of your query but you can take a look at the database api or search google.
