Order by Post by title

I have added the following code to functions.php but it is still showing the posts by the default order (newest to oldest).

function my_change_sort_order($query){
        if ( is_post_type_archive( 'products' ))
		{
           $query->set( 'orderby', 'title' );
           $query->set( 'order', 'ASC' );
		}
    }
add_action( 'pre_get_posts', 'my_change_sort_order');

I have hundreds of posts and the filter does a great job filtering them by category and subcategory, but they are not ordered by title.

Hi Sue,

The filter doesn’t actually have anything to do with how you choose to display the posts. So you’re on the right track BUT the conditional is_post_type_archive() does not work when you’re also filtering on taxonomies (read upon the codex) so you’ll have to extend your conditional to cover the taxonomy archives as well. I haven’t tested this but I think it should work:

function alter_post_order( $query ) {
    if ( is_admin() || ! $query->is_main_query() )
        return;

    if ( is_post_type_archive( 'products' ) || is_tax(array('taxslug', 'anothertaxslug')) ) {
        $query->set( 'orderby', 'title' );
        $query->set( 'order', 'ASC' );
        return;
    }
}
add_action( 'pre_get_posts', 'alter_post_order', 1 );

Hi Jonathan,
Thanks for your prompt answer and help.
Code worked!

No problem ?? Glad it worked out for you.
