Question

我遇到了一个我无法解决的问题。

我创建了一个类似Facebook的墙，一切正常。我从未做过的就是以这种方式回复评论;我对如何将评论返回到帖子帖子感到茫然。

这是我的代码

模特

class Main extends \Model {

    static function post_stream()
    {
        DB::set_charset('utf8');
        $query = DB::insert('stream_post');

        $query->set(array(
            'stream_text' => \Input::post('stream_post'),
            'user_id' => \Session::get('sentry_user'),
            //'date' => time(),
        ));

        $query->execute();
    }

    static function get_stream()
    {
        $query = DB::select()->from('stream_post');
        $query->join('users_metadata');
        $query->on('stream_post.user_id', '=', 'users_metadata.user_id');
        $query->order_by('stream_post.stream_id', 'DESC');
        $result = $query->execute();
        foreach($result as $row)
        {
            $data[] = $row;
        }
        return $data;
    }

    static function post_stream_comment()
    {
        $query = DB::insert('stream_comment');

        $query->set(array(
            'user_id' => \Session::get('sentry_user'),
            'stream_id' => \Input::post('comment_post'),
            'comment_text' => \Input::post('comment_text'),
            )
        );

        $query->execute();
    }

查看（我使用jQuery加载加载）

<div class="stream-posts">
    <?php foreach($posts as $post): ?>
        <div id="post_<?php echo $post['stream_id']; ?>" class="span6 stream-content">
            <span class="user"><a href="#"><?php echo $post['full_name']; ?></a></span>
            <p><?php echo Input::auto_link(Input::nl2br_limit($post['stream_text'], 2)); ?></p>
            <div class="clear"></div>
            <div class="feedback">
                <a href="#" class="like" rel="nofollow">Tetszik</a> - 
                <a href="#" class="comment" rel="nofollow">Hozzászólás</a>
            </div>
            <div class="clear"></div>
            <div class="stream-comment">
                <form class="stream-comment-form">
                    <input type="hidden" name="comment_post" value="<?php echo $post['stream_id']; ?>">
                    <textarea name="comment_text"></textarea>
                    <button type="submit" class="btn btn-primary btn-mini pull-right">Hozzászólok</button>
                </form>
            </div>
        </div>
        <div class="clear"></div>
    <?php endforeach; ?>
</div>

控制器

function action_loadstream()
    {

        $data['posts'] = Main::get_stream();
        $data['comments'] = Main::get_stream_comment();
        return View::forge('main/loadstream', $data);
    } 

    function action_post_stream()
    {

        Main::post_stream();
        $data['get'] = Main::get_stream();
        $stream = json_encode(
            array(
                'full_name' => $data['get'][0]['full_name'],
                'stream_text' => Input::auto_link(Input::nl2br_limit($data['get'][0]['stream_text'], 2)),
                'stream_id' => $data['get'][0]['stream_id'],
                )
            );
        return $stream;
    }

的jQuery

//stream load
        $('#stream-load').load(site_url + "main/loadstream", function(){
            //oembed();
            $('.stream-comment textarea').elastic();
    }); 

//stream comment send
            $('.stream-comment-form').on('submit', function(){
                var commentData = $(this).serialize();
                $.ajax({
                    type: "post",
                    url: site_url + "main/post_stream_comment",
                    data: commentData,
                    success: function()
                    {
                        alert('yay');
                    }
                });
                return false;
            });

        }, 100000).hide().fadeIn("slow");


    function embedHtml(stream)
    {
        var html = '';
            html += '<div class="span6 stream-content">';
            html += '<p class="stream-user"><a href="#">'+stream.full_name+'</a></p>';
            html += '<p>'+stream.stream_text+'</p>';
            html += '<div class="clear"></div>';
            html += '<div class="feedback">';
            html += '<a href="">Tetszik</a> - ';
            html += '<a href="#" class="comment">Hozzászólás</a>';
            html += '</div>';
            html += '<div class="clear"></div>';
            html += '</div>';
            html += '<div class="clear"></div>';
        return html;
    }

    //stream post send
    $('#stream-form').on('submit', function(){
        var streamData = $(this).serialize();
        $('#stream-submit').attr('disabled', 'disabled');
        $.ajax({
            type: "post",
            url: site_url + "main/post_stream",
            data: streamData,
            dataType: "json",
            success: function(stream)
            {

                $('#stream-submit').removeAttr('disabled', 'disabled');
                $('#stream textarea').val('');
                $('#stream-load').prepend(embedHtml(stream));
                $('.stream-posts:first-child').hide().slideDown("slow");
                //oembed();
            }
        });
        return false;
    });

首先，我不希望任何人为我写这个，我只是想请一位经验丰富的开发人员查看我的代码并给我一些关于返回注释逻辑的提示。

Answer 1

当你有stream posts数组时，你可以从中获取id，然后对db进行一次查询，以获取所有相关的注释。循环遍历，并将其附加到post对象/数组。它类似于ORM渴望加载模式。所以：

// get all the post ids
$post_ids = Arr::pluck($result, 'id'); // since 1.3

// fetch all relating comments in one query
$comments = DB::select()
    ->from('stream_comments')
    ->where('post_id', 'in', $post_ids)
    ->execute()
    ->as_array();

// attach them to the original result set.
foreach($comments as $comment)
{
    is_array($result[$comments['post_id']]) or $result[$comments['post_id']] = array();

    $result[$comments['post_id']][] = $comment;
}

Answer 2

您应该使用ORM在帖子之间建立关系并收集相关评论。这就是我要做的。
