我也很难找到 Kohana3 的示例，bestattendance 的示例是 Kohana2。
这是我在自己的测试中整理的一个示例：
应用程序/类/模型/news.php
<?php defined('SYSPATH') OR die('No Direct Script Access');
Class Model_News extends Model
{
/*
CREATE TABLE `news_example` (
`id` INT PRIMARY KEY AUTO_INCREMENT,
`title` VARCHAR(30) NOT NULL,
`post` TEXT NOT NULL);
*/
public function get_latest_news() {
$sql = 'SELECT * FROM `news_example` ORDER BY `id` DESC LIMIT 0, 10';
return $this->_db->query(Database::SELECT, $sql, FALSE)
->as_array();
}
public function validate_news($arr) {
return Validate::factory($arr)
->filter(TRUE, 'trim')
->rule('title', 'not_empty')
->rule('post', 'not_empty');
}
public function add_news($d) {
// Create a new user record in the database
$insert_id = DB::insert('news_example', array('title','post'))
->values(array($d['title'],$d['post']))
->execute();
return $insert_id;
}
}
应用程序/消息/errors.php
<?php
return array(
'title' => array(
'not_empty' => 'Title can\'t be blank.',
),
'post' => array(
'not_empty' => 'Post can\'t be blank.',
),
);
应用程序/类/控制器/news.php
<?php defined('SYSPATH') OR die('No Direct Script Access');
Class Controller_News extends Controller
{
public function action_index() {
//setup the model and view
$news = Model::factory('news');
$view = View::factory('news')
->bind('validator', $validator)
->bind('errors', $errors)
->bind('recent_posts', $recent_posts);
if (Request::$method == "POST") {
//added the arr::extract() method here to pull the keys that we want
//to stop the user from adding their own post data
$validator = $news->validate_news(arr::extract($_POST,array('title','post')));
if ($validator->check()) {
//validation passed, add to the db
$news->add_news($validator);
//clearing so it won't populate the form
$validator = null;
} else {
//validation failed, get errors
$errors = $validator->errors('errors');
}
}
$recent_posts = $news->get_latest_news();
$this->request->response = $view;
}
}
应用程序/视图/news.php
<?php if ($errors): ?>
<p>Errors:</p>
<ul>
<?php foreach ($errors as $error): ?>
<li><?php echo $error ?></li>
<?php endforeach ?>
</ul>
<?php endif ?>
<?php echo Form::open() ?>
<dl>
<dt><?php echo Form::label('title', 'title') ?></dt>
<dd><?php echo Form::input('title', $validator['title']) ?></dd>
<dt><?php echo Form::label('post', 'post') ?></dt>
<dd><?php echo Form::input('post', $validator['post']) ?></dd>
</dl>
<?php echo Form::submit(NULL, 'Post') ?>
<?php echo Form::close() ?>
<?php if ($recent_posts): ?>
<ul>
<?php foreach ($recent_posts as $post): ?>
<li><?php echo $post['title'] . ' - ' . $post['post'];?></li>
<?php endforeach ?>
</ul>
<?php endif ?>
要使此代码在默认安装中工作，您必须启用数据库模块并将其配置为进行身份验证。然后您可以使用默认配置从index.php/news 访问它。
它在 Kohana 3.0.7 中进行了测试，应该为您提供如何布局代码的良好起点。与其他框架不同，Kohana 似乎对于逻辑的放置位置非常开放，所以这对我来说是有意义的。如果您想使用 ORM 而不是滚动自己的数据库交互，它有自己的验证语法，您可以找到它here http://kohanaframework.org/guide/tutorials.orm
