wordpress Make Archives.php Include Custom Post Types
Archives.php only shows content of type 'post', but you can alter it to include custom post types. Add this filter to your functions.php file:
function namespace_add_custom_types( $query ) {
if( is_category() || is_tag() && empty( $query->query_vars['suppress_filters'] ) ) {
$query->set( 'post_type', array(
'post', 'your-custom-post-type-here'
));
return $query;
}
}
add_filter( 'pre_get_posts', 'namespace_add_custom_types' );
