我正在使用 Kohana 3.2 和 Bootstrap 2.3.0 开发迷你博客，这是一个数据库结构表。

CREATE TABLE IF NOT EXISTS `entries` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `entry_title` varchar(255) NOT NULL,
  `entry_content` text NOT NULL,
  `entry_created_date` datetime NOT NULL,
  `entry_edited_date` datetime NOT NULL,
  `entry_created_ip` varchar(40) NOT NULL,
  `entry_edited_ip` varchar(40) NOT NULL,
  `entry_published` tinyint(1) NOT NULL,
  `entry_published_comment` tinyint(1) NOT NULL,
  `entry_hits` int(11) NOT NULL,
  `catentry_id` tinyint(2) NOT NULL,
  `user_id` int(11) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=MyISAM  DEFAULT CHARSET=utf8;

CREATE TABLE IF NOT EXISTS `comments` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `comment_message` text NOT NULL,
  `comment_date` datetime NOT NULL,
  `comment_ip` varchar(40) NOT NULL,
  `entry_id` int(11) NOT NULL,
  `user_id` int(11) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=MyISAM  DEFAULT CHARSET=utf8;

这是我的项目位置。C:\wamp\www\iblog

创建模型条目。C:\wamp\www\iblog\application\classes\model\entry.php

<?php

defined('SYSPATH') or die('No direct script access.');

class Model_Entry extends ORM {
    protected $_belongs_to = array(
        'catentry' => array(),
        'user' => array()
    );

    protected $_has_many = array(
        'comments' => array()
    );
}

创建模型注释。C:\wamp\www\iblog\application\classes\model\comment.php

<?php

defined('SYSPATH') or die('No direct script access.');

class Model_Comment extends ORM {
    protected $_belongs_to = array(
        'entry' => array(),
        'user' => array()
    );
}

在控制器管理中创建函数入口。C:\wamp\www\iblog\application\classes\controller\manage.php

function action_entry() {
        if (Session::instance()->get('user') == null && Session::instance()->get('user')->usertype_id != 1) {
            $this->template->content = View::factory('user/login');
        } else {

            // Get the total count of records in the enry table
            $count = ORM::factory('entry')->find_all()->count();

            // Create an instance of Pagination class and set values
            $pagination = Pagination::factory(array(
                        'total_items' => $count,
                        'items_per_page' => 10,
                    ));
            $pagination->route_params(array('controller' => $this->request->controller(), 'action' => $this->request->action()));

            // Load specific results for current page
            $entries = ORM::factory('entry')
                    ->order_by('id')
                    ->limit($pagination->items_per_page)
                    ->offset($pagination->offset)
                    ->find_all();

            // Render the pagination links
            $page_links = $pagination->render();

            // Define our template view and bind to variables
            $this->template->content = View::factory('manage/entry')
                    ->bind('count', $count)
                    ->bind('entries', $entries)
                    ->bind('page_links', $page_links);
        }
    }

创建视图条目。C:\wamp\www\iblog\application\views\manage\entry.php

问题。我如何计算评论计数值的评论？

鉴于“foreach”正文，您可以这样写：

<?php echo $entry->comments->count_all(); ?>

在您看来，在 for 循环中，尝试插入：

<?php echo $entry->comments->find_all()->count(); ?>

这应该可以工作，因为您将条目标记为 has_many 评论。
