Reply To: Filtering Archives Using Checkbox Custom Fields

@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:

• Women
• Babies
• Children

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):
