Continuing on from the previous tutorial where we added custom columns, we are now going to make these columns sortable like the regular default columns in WordPress (such as post/page title and publish date).

For simplicity, we will continue to work in our functions.php file. You can edit this file by going to Appearance > Editor in your WordPress admin panel, or using a text editor with FTP.

// Make columns sortable
add_filter( 'manage_edit-cf_cats_sortable_columns', 'cats_sortable_cols' );

	$columns['toy'] = 'toy';

	return $columns;
