Show location sub-category instead of main location category

Hi…

I am trying to make some customization to a website but I am not very keen with PHP.

Theme developer advised which file to edit and I think I found the code I want to change.

Basically, it is a directory theme with pins on the map. Each pin pops up an info window which displays among other stuff the location. The thing I want it to show the last-child of the location category instead of the parent.

The website and the map can be found at http://greenleafmaps.info/golocal-network/

The code is the following:

$javo_result	= Array(
‘state’	=> ‘success’
, ‘post_id’	=> $post->ID
, ‘post_title’	=> $post->post_title
, ‘permalink’	=> get_permalink( $post->ID )
, ‘thumbnail’	=> $javo_this_thumb
, ‘category’	=> $javo_meta_query->cat(‘item_category’, __(‘No Category’, ‘javo_fr’))
, ‘location’	=> $javo_meta_query->cat(‘item_location’, __(‘No Location’, ‘javo_fr’))
, ‘phone’	=> get_post_meta( $post->ID, ‘jv_item_phone’, true )
, ‘website’	=> esc_url( get_post_meta( $post->ID, ‘jv_item_website’, true ) )
, ’email’	=> sanitize_email( get_post_meta( $post->ID, ‘jv_item_email’, true ) )
, ‘address’	=> get_post_meta( $post->ID, ‘jv_item_address’, true )
, ‘author_name’	=> $javo_this_author->display_name
);

I am not sure if this can be done by just changing this one line of code …but my question is what should I put in the ‘location’ array in order to show the last-child of the location instead of the parent..?

If this is not the right place to seek help for such issues…can u advice where?

Kind thanks.
