Get all posts from specific author

Hi !

How to get all posts from a specific author on wordpress? I use the following code to make an array, but it didn’t work.

global $current_user;
get_currentuserinfo();

$args = array(
'author' => $current_user->ID,
'orderby' => 'post_date',
'order' => 'ASC' ,
'posts_per_page' => 1
);
$current_user_posts = get_posts( $args );
