@elliot Do you think this has anything to do with the serialized data the Checkbox Field outputs?
Some of my books are assigned to multiple Book Types, like so:
Book Title: Mums and Babies
Book Type:
Wondering if this is what’s causing the issue.
This is where I’m at currently:
add_action('pre_get_posts', 'my_pre_get_posts');
function my_pre_get_posts( $query ) {
if( is_admin() ) { return; }
$meta_query = $query->get('meta_query'); // get original meta query
if( isset($_GET['type']) ) {
$type = '"' . $_GET['type'] . '"';
$meta_query[] = array(
'key' => 'type',
'value' => $type,
'compare' => 'LIKE',
);
}
$query->set('meta_query', $meta_query); // update the meta query args
return; // always return
}
Works with one value, but not multiple values (.com/?type=women,babies):
