Problem:
How to show no initial results with a custom search View?
Solution:
All posts are shown initially, and filters narrow-down the results, eliminating the non-matching ones.
You can add code that uses the Views API to detect whether any filters have been set, and if not (such as when initially loading the page) remove all of the results.
A custom search View includes a filter, for what looks like a taxonomy in your case.
Such filters work by narrowing down the results.
So the starting point is always "All results", and then when the user selects a filter the results update to show only the matching posts.
It doesn't look like you are showing any results, whether a filter has been selected or not.
I'm guessing that what you want is, before a filter is selected, to show NO results, and only after the filter has been selected show the matching results.
Would that be right?
And while showing no initial results you want to display a message repeating the call to first select the area.
I've shared a generic solution using this before, let me repeat it here:
/**
* No initial results
*
* Don't show View results until a filter has been applied
*
* Tests for custom field filters, taxonomy filters, or text searches
*/
function tssupp_no_initial_results( $query_results, $view_settings, $view_id ){
$target_views = array( 123 ); // Edit to add IDs of Views to add this to
if ( in_array( $view_id, $target_views ) ) {
// if there is a search term set
if ( !isset( $query_results->query['meta_query'] ) && !isset( $query_results->query['tax_query'] ) && !isset( $query_results->query['s'] ) ) {
$query_results->posts = array();
$query_results->post_count = 0;
$query_results->found_posts = 0;
}
}
return $query_results;
}
add_filter( 'wpv_filter_query_post_process', 'tssupp_no_initial_results', 10, 3 );
You need to add a custom code snippet with the above at Toolset > Settings > Custom Code, and you will need to edit the ID of your View ("123" in the example above, and you can provide a list of IDs here if it should apply to multiple Views).
So when your page first loads and has no filters set, you will get the "No results found" message which appears inside the wpv-no-items-found shortcodes in the View output. You can replace this with markup that displays your "Please select the area" message.
