如何将前端文章作者分配给当前登录用户。我有前端帖子提交表单（wp\\u insert\\u post）抛出了ajax帖子请求。所以用户登录并通过前端表单发布。我需要得到哪个用户提交了帖子。我对编码是新手。

public function submit_testimonial()
    {  
        if (! DOING_AJAX || ! check_ajax_referer(\'testimonial-nonce\', \'nonce\') ) {
            return $this->return_json(\'error\');
        }
        $name = sanitize_text_field($_POST[\'name\']);
        $data = array(
            \'name\' => $name,
        );
        $args = array(
            \'post_title\' => $name,
            \'post_content\' => $message,
            \'post_author\' => 1,
            \'post_status\' => \'publish\',
            \'post_type\' => \'testimonial\',
            \'author\' => $current_user->ID,
            \'meta_input\' => array(
                \'_zon_testimonial_key\' => $data
            )
        );
        $postID = wp_insert_post( $args );
        if ($postID) {
            return $this->return_json(\'success\'); 
        }  
    }
    public function return_json( $status ) {
        $return = array(
            \'status\' => $status
            );
            wp_send_json($return);    
    }
