Display Random Post in Author Page

Question

By default when we open any author's page, WordPress displays latest posts from that author first.

What I want: If anyone opens any author's page, it will display random posts from that author.

I have searched everywhere but I couldn't find any solution.

Answer 1

use this query in themes functions.php

function ng_author_query( $query ) {
    if ( $query->is_author()
        && $query->is_main_query() ) {
            // your code to set $current_user_name here
            $query->set( 'orderby', 'rand' );
    }
}
add_action( 'pre_get_posts', 'ng_author_query' );

Let me know if you have any problem?
