Ok so I’ve managed to get my images pulling through even when filtering which was a simple fix of changing the Return Value of the “film_poster” field to Image ID. It now works when I’m viewing the standard /films page as well as if I send a query (e.g. /films/?film_genre=Action).
However, I’m still having problems with the filters disappearing when the query is sent (e.g. apexcinemas.andrewcourtney.co.uk/films/?film_genre=Action) – any ideas?
Below is the code I have running in the functions.php page, taken from the ACF tutorial I mentioned before 🙂
// filter film genre
add_action(‘pre_get_posts’, ‘my_pre_get_posts’);
function my_pre_get_posts($query){
// validate
if(is_admin()){
return;
}
// Get original meta query
$meta_query[] = $query->get(‘meta_query’);
// allow the url to alter the query
// e.g. ?film_genre=comedy
if(isset($_GET[‘film_genre’])){
$film_genre = explode(‘,’, $_GET[‘film_genre’]);
// Add our meta query to the original meta queries
$meta_query[] = array(
‘key’ => ‘film_genre’,
‘value’ => $_GET[‘film_genre’],
‘compare’ => ‘IN’,
);
}
// update the meta query arguments
$query->set(‘meta_query’, $meta_query);
// always return
return;
}
Thanks in advance!
