Problem: I have a custom search View with two control fields. I would like to require the User to select a value in both fields before any results are shown. As it is now, when the page loads all the results are shown. I would like to show no results.
Solution: @e have an API that is helpful for this situation: wpv_filter_query_post_process. This will allow you to intercept the search results and test the query. If either option is blank, or 0, show no results.
// custom filter that shows no search results if either filter is empty
add_filter( 'wpv_filter_query_post_process', 'drop_empty_search_query_post_process', 10, 3 );
function drop_empty_search_query_post_process( $query, $view_settings, $view_id ) {
$ids = array(12345);
if (in_array($view_id, $ids)){
if (
// supplier type filter needs to check for not '0' as well as not empty
( isset($_GET['wpv-supplier-category']) && $_GET['wpv-supplier-category'] != '0' )
&&
// location filter needs to check for not '0' as well as not empty
( isset($_GET['wpv-area-served']) && $_GET['wpv-area-served'] != '0' )
) {
} else {
$query->posts = array();
$query->found_posts = 0;
$query->post_count = 0;
}
}
return $query;
}
Replace 12345 with the numeric ID of this View. You can customize the "No results found" message in the View's Loop Output editor panel.
Problem: I would like to delete a post when a User's WooCommerce Subscription is canceled or expires.
Solution: Toolset does not have any hooks that will help you respond to WooCommerce Subscription events, so I would ask WooCommerce Subscriptions' support team if they offer an API that will allow you to perform some action when a subscription is canceled or expires. If so, then you can use some custom code to set the post to "draft" status, which would effectively remove it from the front-end of the site. You could reinstate the post at any time if the subscription is renewed. Here's an example ticket on stackoverflow that modifies a post's status: https://wordpress.stackexchange.com/questions/12512/how-to-update-page-status-from-publish-to-draft-and-draft-to-publish
