Script

그러기 위해선 대댓글을 만들 form이 필요합니다.

Js로 대댓글 버튼을 누르면 바로 그 아래의 대댓글을 만들 수 있는 form을 동적으로 추가해 봅시다.

HTMl은 복사하는 게 정신에 이롭습니다.

script의 form을 보면 bbs/reply/create로 POST 요청을 하는 걸 알 수 있습니다

저번 포스트에서 분기를 나눈 게 대댓글도 같이 사용하기 위함입니다.

bbs/assets/script/read.js

$(document).ready(function () {
   ...

    // 대댓글 작성 폼 생성 기능
    $(".btnSubReply").click(function (){
        let replyIdx = $(this).parent().find(".reply-idx").val();
        let postIdx = $("#postIdx").val();
        let subReplyFormExist = $("#subReplyForm").length > 0;
        if (subReplyFormExist) {
            $("#subReplyForm").remove();
        }

        $(this).parent().parent().after(
            "<div class=\"mt-4 card ml-4\" id=\"subReplyForm\">\n" +
            "            <div class=\"card-body\">\n" +
            "                <form action=\"/bbs/reply/create\" method=\"post\">\n" +
            "                    <h5>대댓글</h5>\n" +
            "                    <input name=\"post_idx\" type=\"hidden\" class=\"reply-idx\" value=\""+postIdx+"\"/>\n" +
            "                    <div class=\"media-body mb-3\">\n" +
            "                        <input name=\"parent_idx\" type=\"hidden\" name=\"post_idx\" value=\""+replyIdx+"\">\n" +
            "                        <div class=\"form-row\">\n" +
            "                            <div class=\"form-group col-md-6\">\n" +
            "                                <label for=\"name\">Name</label>\n" +
            "                                <input type=\"text\" class=\"form-control\" name=\"name\" placeholder=\"Name을 입력해주세요.\">\n" +
            "                            </div>\n" +
            "                            <div class=\"form-group col-md-6\">\n" +
            "                                <label for=\"password\">Password</label>\n" +
            "                                <input type=\"password\" class=\"form-control\" name=\"pw\"\n" +
            "                                       placeholder=\"Password를 입력해주세요.\">\n" +

            "                    </div>\n" +
            "                    <button class=\"btn btn-primary\" type=\"submit\">댓글 작성</button>\n" +
            "                </form>\n" +
            "            </div>\n" +
            "        </div>")
    })
});

Model

마지막으로 subReplyCreate와 getSubReplies를 만들어줍시다.

bbs/Model/Reply.php

<?php

namespace Model;

use PDOException;

class Reply extends BaseModel
{	
	...

    /**
     * 대댓글 만들기
     * @param $postIdx
     * @param $parentIdx
     * @param $name
     * @param $pw
     * @param $content
     * @return bool
     */
    public function subReplyCreate($postIdx, $parentIdx, $name, $pw, $content): bool
    {
        try {
            $hashed_pw = password_hash($pw, PASSWORD_DEFAULT);
            $query = "INSERT INTO replies (post_idx, parent_idx, name, pw, content) VALUES (:post_idx, :parent_idx, :name, :pw, :content)";
            return $this->conn->prepare($query)->execute([
                'post_idx' => $postIdx,
                'parent_idx' => $parentIdx,
                'name' => $name,
                'pw' => $hashed_pw,
                'content' => $content
            ]);
        } catch (PDOException  $e) {
            error_log($e->getMessage());
            return false;
        }
    }


    /**
     * 대댓글 목록 가져오기
     * @param $parentIdx
     * @return array
     */
    public function getSubReplies($parentIdx): array
    {
        try {
            $query = "SELECT * FROM replies WHERE parent_idx = :parent_idx ORDER BY idx DESC";
            $stmt = $this->conn->prepare($query);
            $stmt->execute([
                'parent_idx' => $parentIdx,
            ]);
            return $stmt->fetchAll();
        } catch (PDOException $e) {
            error_log($e->getMessage());
            return [];
        }
    }
}

결과는 아래와 같습니다.
