Wordpress WP-Query issue when applying filters-CodePudding

I am trying apply filters to my Wordpress query. I am having issues with getting the author query to work. from my url I pass the name of the author however the filter is not working. I am still getting all post from all authors. Can someone point me in the right direction to query with author

add_filter("wcra_pictures_callback", "wcra_pictures_callback_handler");

function wcra_pictures_callback_handler($param) {
  //$param = All GET/POST values will be received from endpoint
  
  // Get Posts
    $posts = get_posts([
        'post_type' => $param['post_type'],
        'author' => $param['author'],
        'orderby' => $param['orderby'],
        'order'   => $param['order'],
        'posts_per_page' => $param['posts_per_page'],
    ]);
  
  return $posts;
}

CodePudding user response：

author expects you to pass the author ID, which is an int, and not the author name, if you want to query using author name, you should use author_name in which case you should pass the user_nicename and not the actual name of the author.

Ex.

$posts = get_posts([
  'post_type'      => $param['post_type'],
  'author_name'    => $param['author'], // the name must match the user_nice name in their profile
  'orderby'        => $param['orderby'],
  'order'          => $param['order'],
  'posts_per_page' => $param['posts_per_page'],
]);
