我想要做的是创建一个该线程有多少回复的列表。我可以计算好答复的数量。加入计数仍然没有显示正确的计数
但我想能做的是计算用户线程也。
这就是看起来像什么。它只是从我的答复表中统计它似乎无法让它从我的连接算起。

应该出来放像

问题如何确保它可以指望从join()方法的线程表中的用户ID?
模型函数
public function number_of_replies($user_id, $thread_id) {
$this->db->select('*');
$this->db->from('reply');
$this->db->join('thread', 'thread.user_id = reply.user_id', 'left');
$this->db->where('reply.user_id', $user_id);
$query = $this->db->get();
if ($query->num_rows() > 0) {
return $query->num_rows();
} else {
return 0;
}
}
控制器
<?php
class Who_replied extends MX_Controller {
public function __construct() {
parent::__construct();
}
public function index($thread_id = '') {
$data['users'] = array();
$data['thread_id'] = $thread_id;
$results = $this->get_users_who_replied($thread_id);
if (isset($results)) {
foreach ($results as $result) {
$data['users'][] = array(
'user_id' => $result['user_id'],
'username' => $result['username'],
'total' => $this->number_of_replies($result['user_id'], $thread_id),
);
}
}
$data['total_posts'] = '';
return $this->load->view('default/template/forum/categories/who_replied_view', $data);
}
public function get_users_who_replied($thread_id) {
$this->db->select('user.username, user.user_id, reply.thread_id');
$this->db->distinct();
$this->db->from('reply');
$this->db->join('user', 'user.user_id = reply.user_id', 'left');
$this->db->join('thread', 'thread.user_id = user.user_id', 'left');
$this->db->where('reply.thread_id', $thread_id);
$this->db->order_by('thread.user_id', 'desc');
$query = $this->db->get();
if ($query->num_rows() > 0) {
return $query->result_array();
}
}
public function number_of_replies($user_id, $thread_id) {
$this->db->select('*');
$this->db->from('reply');
$this->db->join('thread', 'thread.user_id = reply.user_id', 'left');
$this->db->where('reply.user_id', $user_id);
$query = $this->db->get();
if ($query->num_rows() > 0) {
return $query->num_rows();
} else {
return 0;
}
}
}
