在函数内使用A $ _GET变量进行数据库插入？

希望有人可以解释我遇到的问题 .

我有一个表单，用于向页面添加注释;

<?php if(app('current_user')->role != 'user'): ?>
        <div class="leave-comment">
            <div class="control-group form-group">
                <h5><?= trans('leave_comment'); ?></h5>
                <div class="controls">
                    <textarea class="form-control" id="comment-text"></textarea>
                </div>
            </div>
            <div class="control-group form-group">
                 <div class="controls">
                    <button class="btn btn-success" id="comment">
                        <i class="fa fa-comment"></i>
                        <?= trans('comment'); ?>
                    </button>
                </div>
            </div>
        </div>
    <?php else: ?>
        <p><?= trans('you_cant_post'); ?></p>
    <?php endif; ?>

这使用ajax加载以下情况;

case "postComment":
    echo app('comment')->insertComment(ASSession::get("user_id"), $_POST['comment']);
    break;

哪个负载;

public function insertComment($userId, $comment)
{
    $userInfo = $this->users->getInfo($userId);
    $datetime = date("Y-m-d H:i:s");

    $this->db->insert("as_comments", array(
        "posted_by" => $userId,
        "posted_by_name" => $userInfo['username'],
        "comment" => strip_tags($comment),
        "post_time" => $datetime,
        "FK_DappID" => 1
    ));

    return json_encode(array(
        "user" => $userInfo['username'],
        "comment" => stripslashes(strip_tags($comment)),
        "postTime" => $datetime
    ));
}

这些注释用在一个名为view.php的页面上，我有一个变量，它是从名为$ _GET ['ID']的htis页面的URL设置的 .

SO..

如何将要插入数据库的数组中的“FK_DappID”=> 1更改为$ _GET ['ID']的值？

我尝试过使用“FK_DappID”=> $ _GET ['ID']但它不起作用..

任何帮助都会非常有用 .

谢谢，B .

                    html += "<p>"+res.comment+"</p>";
                    html += "<small>"+res.user+" <em> "+ $_lang.at +res.postTime+"</em></small>";
                    html += "</blockquote>";
                if( $(".comments-comments blockquote").length >= 7 )
                    $(".comments-comments blockquote").last().remove();
                $(".comments-comments").prepend($(html));
                comment.val("");

            }

    });
});

});
