This thread is resolved. Here is a description of the problem and solution.
Problem:
I would like to add a query filter to a view that shows only posts that have a featured image.
Solution:
This can be achieved by using our views custom filters. Add this code in your theme’s or child theme’s functions.php file:
add_filter('wpv_filter_query', 'show_featured', 10, 3);
function show_featured($query, $view_settings,$view_id ) {
if($view_id == 999) //replace view ID
{
$query['meta_key'] = '_thumbnail_id';
}
return $query;
}
