如果我理解正确，您想使用自己的选择表单来更新帖子的发布状态，而不是发布/取消发布按钮？像这样的东西可以做到这一点：

function save_my_data($post_id){
    if($_POST[\'publish\'] == \'yes\' && get_post_status($post_id) != \'publish\'){ //whatever your post variable is
        remove_action(\'save_post\', \'save_my_data\'); //if you don\'t unhook the function you\'ll have an infinite loop
        wp_publish_post($post_id);
        add_action(\'save_post\', \'save_my_data\'); //rehook the function       
    }
    if($_POST[\'publish\']) == \'no\' && get_post_status($post_id) == \'publish\'){
        remove_action(\'save_post\', \'save_my_data\'); //if you don\'t unhook the function you\'ll have an infinite loop
        wp_update_post(array(
            \'ID\' => $post_id,
            \'post_status\' => \'draft\'
        ));
        add_action(\'save_post\', \'save_my_data\'); //rehook the function
    }
}
