Problem: I would like to define a custom order for the taxonomy terms in a custom search filter.
Solution: The options you have for taxonomy term order are somewhat limited, and do not correspond to the order you define in the display_values attribute. My recommendation is to use the following filter shortcode:
[wpv-control-post-taxonomy taxonomy="military-action" type="select" default_label="Select Conflict Below" url_param="wpv-military-action" orderby="id"]
Then add this custom filter to your child theme's functions.php file:
function custom_taxonomy_filter_order( $terms, $taxonomies, $args, $term_query ){
global $required_orderby;
// Specify taxonomy, current setting for orderby, and required order (slugs) here
$taxonomy = "military-action";
$current_orderby = "id";
$required_orderby = array(
"wwi","wwii","korean-war","vietnam-war","gulf-war","war-in-iraq","war-on-terror","unknown"
);
if ( $taxonomies[0] == $taxonomy && $args['orderby'] == $current_orderby ){
usort( $terms, "custom_term_compare" );
};
return $terms;
}
add_filter( 'get_terms', 'custom_taxonomy_filter_order', 10, 4);
/**
* Customise sort function
*
*/
function custom_term_compare( $a, $b ){
global $required_orderby;
$a_key = array_search( $a->slug, $required_orderby );
$b_key = array_search( $b->slug, $required_orderby );
if ( $a_key == $b_key ) {
return 0;
}
return ( $a_key < $b_key ) ? -1 : 1;
}

I have several taxonomy filters setup on my view, and I attempted to set a custom order on one of the filters. The filtering works as expected there, but my other taxonomy filters now return nothing. The filter I tried to customize is the one with the url parameter "wpv-military-action". Here is my code:
<div class="form-group">
[wpv-control-post-taxonomy taxonomy="military-branch" type="select" default_label="Select Branch Below" url_param="wpv-military-branch"]
</div>
<div class="form-group">
[wpv-control-post-taxonomy taxonomy="phs-graduation-year" type="select" default_label="Select Class Below" url_param="wpv-phs-graduation-year"]
</div>
<div class="form-group">
[wpv-control display_values="Select Conflict Below,WWI,WWII,Korean War,Vietnam War,Gulf War,War In Iraq,War on Terror,Unknown" values="0,wwi,wwii,korean-war,vietnam-war,gulf-war,war-in-iraq,war-on-terror,unknown" type="select" default_label="Select Conflict Below" url_param="wpv-military-action"]
</div>
<div class="form-group">
[wpv-control-post-taxonomy taxonomy="medal" type="select" default_label="Select Medal Below" url_param="wpv-medal"]
</div>
