The authorpage is begin generated, and every post that an author has made will be shown. However I only want to show posts from a specific category (id=1). So basically, when you visit mysite.com/author/John you should see only posts from John, with category ID=1 and on mysite.com/author/Bob you should see only posts from Bob, with category ID=1.

When I do this in ARCHIVE.PHP:

            /* Start the Loop */ 
                    query_posts('cat=1');                               
                while (have_posts()) {
                    the_post();
                    get_template_part('content', get_post_format());
                }
                    

Unfortunately, when I do this, every post in category 1, will be shown on every author page...(You see Bobs and Johns posts on Johns author-page).

I have also tried this, but same results as above:

$curauth = get_userdata($row->ID);
$user_link = get_author_posts_url($curauth->ID);
$posts = get_posts(array(
                         'author' => $curauth->ID,
                         'cat' => 1
                         'posts_per_page' => -1,
                        )
                  );
$post_count = count($posts);

2 questions.

1.Should I code in Archive.php or should I make the adjustments in author.php (not available in the theme).

2. More importantly, how do I show catID=1 for every author ?

Thank you in advance...
