6月4 Smarty练习增删改

练习Smarty的增删改所需要用到的数据库名称：timu,xuanxiang,kemu,nandu,leixing，然后使用smarty模板将前端后后台分割开来：

主页后台页面：zhupm.php

<?php
//将题目表显示在页面
include("../init.inc.php");

include("../DBDA.php");
$db = new DBDA();

$sql = "select * from timu";
$attr = $db->Query($sql);

$smarty->assign("shuju",$attr);

$smarty->display("zhu0603pm.html");

View Code

主页前段显示页面:zhu0603pm.html

<html>
<head>
<meta charset="utf-8" />
</head>
<title>Smarty的增删改查</title>

<body>
<h1>主页面</h1>
<br />

<table border="1" cellpadding="0" cellspacing="0" width="100%">
    <tr>
        <td>题目名称</td>
        <td>答案</td>
        <td>科目</td>
        <td>难度</td>
        <td>类型</td>
        <td>操作</td>
    </tr>
 
<{foreach $shuju as $v}>
<tr>
    <td><{$v[1]}></td>
    <td><{$v[2]}></td> 
    <td><{$v[3]}></td> 
    <td><{$v[4]}></td> 
    <td><{$v[5]}></td> 
    <td><a href="shanchu.php?code=<{$v[0]}>">删除</a>&nbsp;&nbsp;<a href="xiugai.php?code=<{$v[0]}>">修改</a></td> 
</tr>
<{/foreach}>
