Views plugin lets you build your own custom search for any content type. These searches can be based on post content, taxonomies and custom fields. When you ask for help or report issues, make sure to tell us settings for your custom search.
Problem: I would like to set up a hierarchical post relationship system using a series of one-to-many post relationships. Country should be parent of State, State should be parent of Town, Town should be parent of Ad. I would like to allow site visitors to use a custom search View to filter Ads. Everything is working okay but I want to give my clients the ability to add an Ad at the State level, and I want the custom search filter to be able to find these Ads as well.
Solution: There isn't a perfect solution to this problem, because only one post relationship custom search filter is supported. You can add another post relationship for State > Ads, to allow your clients to associate an Ad at the State level. Then you can create a second View of Ads filtered by post relationship, using the Ad > State post relationship, and set by a URL parameter. Place this second View of Ads on the same page as the original custom search View, but display only the results and no filters.
There are limitations to this approach, for example, AJAX updates are not supported.
