Question

How to grab all type of attachments, but images?

Answer 1

WordPress has a function, get_allowed_mime_types, which will return all allowed types. We can filter this list and exclude any types containing image, then query for all remaining types by passing them as a comma separated list to post_mime_type. This may not be the most efficient way to do it, you may be better off filtering posts_where, but it'll work.

$filtered_mime_types = array();

foreach( get_allowed_mime_types() as $key => $type ):
    if( false === strpos( $type, 'image' ) )
        $filtered_mime_types[] = $type;
endforeach;

$args = array(
    'post_type' => 'attachment',
    'posts_per_page' => -1,
    'post_status' => 'any',
    'post_mime_type' => implode( ',', $filtered_mime_types )
);

$results = new WP_Query( $args );
