您可以使用wp_insert_post 作用

   $my_post = array(
            \'post_title\'    => \'Some titles\',
            \'post_content\'  => \'This is my post content\',
            \'post_status\'   => \'publish\',
            \'post_author\'   => 1,
            \'post_category\' => array(1, 2, 9000)
            );

            // Insert the post into the database
            wp_insert_post( $my_post );

        }
