下面是所谓的"菜单"小练习，有四个文件，其中的mainpage.php不变，增加了一个menu库文件，放在Application/libraries目录下。entrypage.php增加了一点东西，变化也不是很大。
entrypage.php:
<html>
<head>
<title><?=$mytitle?></title>
</head>
<body>
<?=$menu?><br><br>
<?=$text ?>
<?=form_open('start/assessme');?>
<input type="text" name="username" value="username"/>
<input type="text" name="password" value="hi"/>
<input type="submit" value="submit" />
<input type="reset" value="reset"/>
</form>
</body>
</html>
menu.php:
<?php
class Menu
{
function show_menu()
{
$obj=& get_instance();
$obj->load->helper('url');
$menu=anchor("start/hello/fred","Say hello to Fred |");
$menu.=anchor("start/hello/bert","Say hello to Bert|");
$menu.=anchor("start/another_function","Do something else|");
return $menu;
}
}
?>
start:
