I'm using the plugin Ajax WP Query Search Filter (http://wordpress.org/plugins/ajax-wp-query-search-filter/) to search some custom posts I've created.
The filter works great on three custom taxonomies, however I also want to include a filter on a date field where the full date is stored.
The filter I'd like is a dropdown containing each month, as such:
- ... etc...
This would search the date field on its month value. My question is how do I do this?
I know I can create a Custom Meta Field filter, but how I would get it to search on the month part only?
