Reply To: Different Types on multisite

Hi Till,

Well, not possible via settings, but it might be possible via custom coding. Try adding this custom code to the functions.php in your theme/child theme directory. Before editing, please make sure to have a full site back-up just in case!

add_filter( 'asp_results', 'asp_attachment_image_custom', 10, 1 );
function asp_attachment_image_custom( $results ) {
	// Parse through each result item
	foreach ($results as $k=>&$r) {
		// PDF custom image
		if ( isset($r->post_mime_type) && strpos(strtolower($r->post_mime_type), 'pdf') !== false ) {
			$r->image = 'https://archiv.njf.de/wp-content/plugins/download-manager/assets/file-type-icons/pdf.svg';
		}
	}

	return $results;
}
