Codeigniter 带有联接的计数仍不显示正确的计数

我试图做的是创建一个列表，列出这个线程有多少回复。我可以很好地计算回复的数量

但我希望能够做的是计算用户线程也

这就是输出的样子。它只从我的replys表中计数，似乎无法从我的join中计数

Username    Post
demo         2
admin        1

应该像

Username    Post
demo         3 <-- Because the user has asked the Question / "thread" and has replied twice
admin        1

控制器

<?php

class Who_replied extends MX_Controller {

            foreach ($results as $result) {

对2个表用户id列进行求和

public function number_of_replies($user_id, $thread_id) {
    $this->db->select('t1.*, count(t2.user_id)+count(t1.user_id) AS total_posts');
    $this->db->from('reply AS t1');
    $this->db->join('thread AS t2', 't2.user_id = t1.user_id', 'left');
    $this->db->where('t1.user_id', $user_id);
    $query = $this->db->get();

    if ($query->num_rows() > 0) {
        return $query->num_rows();
    } else {
        return 0;
    }
}

Do sum 2表用户id列

public function number_of_replies($user_id, $thread_id) {
    $this->db->select('t1.*, count(t2.user_id)+count(t1.user_id) AS total_posts');
    $this->db->from('reply AS t1');
    $this->db->join('thread AS t2', 't2.user_id = t1.user_id', 'left');
    $this->db->where('t1.user_id', $user_id);
    $query = $this->db->get();

    if ($query->num_rows() > 0) {
        return $query->num_rows();
    } else {
        return 0;
    }
}

我似乎已经让它工作了，主要是现在有更多的测试要做

我所要做的就是创建函数来计算一个回复数和一个线程数

public function replies_by_users($user_id, $thread_id) {
    $this->db->where('user_id', $user_id);
    $this->db->where('thread_id', $thread_id);
    return $this->db->count_all_results('reply');
}

public function thread_by_user($user_id, $thread_id) {
    $this->db->where('user_id', $user_id);
    $this->db->where('thread_id', $thread_id);
    return $this->db->count_all_results('thread');
}

然后将它们组合起来，使用plus
+
然后返回

public function total_replies_and_thread($user_id, $thread_id) {
    return $this->replies_by_users($user_id, $thread_id) + $this->thread_by_user($user_id, $thread_id);
}

然后在数组本身中使用
总数和线程（$user\u id，$thread\u id）
，如下所示

$results = $this->get_replies($thread_id);

    if ($results) {
        foreach ($results as $result) {
            $data['users'][] = array(
                'reply_id' => $result['reply_id'],
                'user_id' => $result['user_id'],
                'thread_id' => $result['thread_id'],
                'username' => $result['username'],
                'total' => $this->total_replies_and_thread($result['user_id'], $result['thread_id'])
            );
        }
    }

现在发出正确的

        $results = $this->get_replies($thread_id);

        if ($results) {

                $data['users'][] = array(

                    'total' => $this->total_replies_and_thread($result['user_id'], $result['thread_id'])
                );
            }
        }

        $data['user_id'] = $user_id;

        return $this->load->view('default/template/forum/categories/who_replied_view', $data);

    }

    // Model code is just on here for testing purpose you should all ways create a model for it self.

        $this->db->from('reply');
        $this->db->join('user', 'user.user_id = reply.user_id');
        $this->db->where('thread_id', $thread_id);
        $this->db->group_by('user_id');
        $this->db->order_by('thread_id', 'desc');
        $query = $this->db->get();

        if ($query->num_rows() > 0) {
            return $query->result_array();
        }
    }

    public function total_replies_and_thread($user_id, $thread_id) {
        return $this->replies_by_users($user_id, $thread_id) + $this->thread_by_user($user_id, $thread_id);
    }

    public function replies_by_users($user_id, $thread_id) {
        $this->db->where('user_id', $user_id);
        $this->db->where('thread_id', $thread_id);
        return $this->db->count_all_results('reply');
    }

    public function thread_by_user($user_id, $thread_id) {
        $this->db->where('user_id', $user_id);
        $this->db->where('thread_id', $thread_id);
        return $this->db->count_all_results('thread');
    }
}

我似乎已经让它工作了，现在大部分时间都需要做更多的测试

我所要做的就是创建函数来计算一个回复数和一个线程数

public function replies_by_users($user_id, $thread_id) {
    $this->db->where('user_id', $user_id);
    $this->db->where('thread_id', $thread_id);
    return $this->db->count_all_results('reply');
}

public function thread_by_user($user_id, $thread_id) {
    $this->db->where('user_id', $user_id);
    $this->db->where('thread_id', $thread_id);
    return $this->db->count_all_results('thread');
}

然后将它们组合起来，使用plus
+
然后返回

public function total_replies_and_thread($user_id, $thread_id) {
    return $this->replies_by_users($user_id, $thread_id) + $this->thread_by_user($user_id, $thread_id);

                'total' => $this->total_replies_and_thread($result['user_id'], $result['thread_id'])
            );
        }
