smarty引擎之练习

关于smarty最直观的感受就是分离了页面中html和php的代码，页面不再混乱，很清晰了……

smarty->assign();//注册

smarty->display();//加载模板

除了老师给的表，kemu,nandu,type都建了表格，便于使用

main.php

<?php

include("./init.inc.php");//加载配置文件
//echo str_replace("\","/",dirname(__FILE__))."/";
include("ChaXun.class.php");//加载类
$db=new ChaXun();
$sql="select * from timu";
$attr=$db->Query($sql);
//var_dump($attr);

$smarty->assign("shuju",$attr);//将要注册内容给smarty
$smarty->display("main.html");

main.html

<html>
<head>
<meta charset="utf-8" />
</head>

<body>
<h1>主页面</h1>
<table width="100%" border="1" cellpadding="0" cellspacing="0">
<tr>
<td>题目名称</td>
<td>答案</td>
<td>所属科目</td>
<td>难度</td>
<td>题目类型</td>
<td>操作</td>
</tr>
<{foreach $shuju as $v}>//遍历smarty传过来的$shuju,这里使用foreach要注意结束foreach
<tr>
<td><{$v[1]}></td>
<td><{$v[2]}></td>
<td><{$v[3]}></td>
<td><{$v[4]}></td>
<td><{$v[5]}></td>
<td><a href="delete.php?code=<{$v[0]}>">删除</a>&nbsp;&nbsp;<a href="update.php?code=<{$v[0]}>">更改</a></td>
</tr>

<{/foreach}>
</table>
<a href="add.php">添加数据</a>

</body>
</html>

add.php

<?php
include("./init.inc.php");
//echo str_replace("\","/",dirname(__FILE__))."/";

$db=new ChaXun();
$sqlkm="select * from kemu";
$akm=$db->Query($sqlkm);
