smarty的设置
<?php

{{/foreach}}

{{$total}}条数据
每页显示{{$rows}}条

{{else}}

</tr>
</table>
<table width="100%" border="1" cellspacing="0" cellpadding="0">
<form action="add.php" method="POST">
<tr>
<td width="20%" align="right">用户名</td>
<td><input type="text" name="username" style="width:400px"></td>
</tr>
<tr>
<td align="right">内容</td>

</tr>
<tr>
<td align="center" colspan="2"><input type="submit" name="submit" value=" 提 交 "></td>
</tr>
</form>
</table>
</body>
</html>
下面是显示程序
<?php
define('ROOT_PATH', dirname(__FILE__));
require_once ROOT_PATH . '/lib/m_html.class.php';
require_once ROOT_PATH . '/lib/m_db.class.php';
$page = $_GET['page'];
$mdb = new m_db();
$html = new m_html('/test_' . $page . '.html', 30);
$num = $mdb->fetch_one('select count(*) as num from test');
$page_arr = $mdb->page($num['num'], $page, 7, 4);
$rs = $mdb->fetch_all('select * from test order by id desc limit ' . $page_arr['start'] . ',' . $page_arr['rows']);
$html->assign('rs', $rs);
$html->assign('web_path', $html->config['web_path'] . '/');
$html->assign($page_arr);
$html->render('index.htm', '/test_' . $page_arr['current_page'] . '.html');
?>
下面是保存留言代码
<?php
define('ROOT_PATH', dirname(__FILE__));
require_once ROOT_PATH . '/lib/m_db.class.php';
require_once ROOT_PATH . '/lib/m_string.class.php';
$_POST = m_string::addslashes($_POST);
$mdb = new m_db();
$mdb->add('test', array('name', 'content'), array($_POST['username'], $_POST['content']));
header('location:test.php');
?>
CREATE TABLE `test` (
`id` int(10) unsigned NOT NULL auto_increment,
`name` varchar(255) NOT NULL,
`content` tinytext NOT NULL,
PRIMARY KEY (`id`)
)
