用smarty模板实现数据的显示修改以及分页

首先根据规则将需要的php和html文件放到相应的文件夹下

php文件

<?php
include("../init.inc.php");
include("../abc.php");
$db = new DBDA();

$sql = "select * from nation";
$arr = $db->Query($sql);

$smarty->assign("shuju",$arr);
$smarty->display("main.html");

html文件

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>无标题文档</title>
</head>

<body>
<h1>数据列表</h1>

<table width="100%" border="1" cellpadding="0" cellspacing="0">

<tr>
<td>代号</td>
<td>名称</td>
<td>操作</td>

</tr>
<{foreach $shuju as $v}>
<tr>
<td><{$v[0]}></td>
<td><{$v[1]}></td>
<td>操作</td>

</tr>
<{/foreach}>

</table>

</body>
</html>

完成以上两步页面数据显示成功

然后做修改代码如下

<tr>
<td>名称</td>
<td>操作</td>
</tr>

<{foreach $shuju as $v}>
<tr>
<td><{$v[0]}></td>
<td><{$v[1]}></td>
<td><a href="xiugai.php?code=<{$v[0]}>">修改</a></td>
</tr>
<{/foreach}>
(光标移不出去了 就在这里面继续写吧)





修改页面是需要独立显示出来的 所以也需要php 和 html

xiugai.php

<?php
include("../init.inc.php");
include("../abc.php");
$db = new abc();

$code= $_GET["code"];

$sql = "select * from nation where code='{$code}'";
$arr= $db->Query($sql);

$smarty->assign("nation",$arr[0]);
$smarty->display("xiugai.html");

xiugai.html：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>无标题文档</title>
</head>

<body>
<h1>修改页面</h1>
<form action="update.php" method="post">
<div>代号：<input type="text" name="code" value="<{$nation[0]}>" /></div>
<div>名称：<input type="text" name="name" value="<{$nation[1]}>" /></div>
<input type="submit" value="修改" />

</form>

</body>
</html>

这样就基本结束了修改的代码

为了用户体验需要做一个分页查询

<?php
include("../init.inc.php");
include("../abc.php");
$db = new abc();
$sall="select count(*) from nation";
$zts=$db->StrQuery($sall);

include("../page.class.php");
$page = new Page($zts,5);


$sql = "select * from nation ".$page->limit;//注意 这里有一个空格 没有的话会报错
$arr = $db->Query($sql);

$smarty->assign("fenye",$page->fpage());
$smarty->assign("shuju",$arr);
$smarty->display("main.html");

在显示的html页面中嵌入<div><{$fenye}></div>

添加一个查询功能

查询代码

<?php
include("../init.inc.php");
include("../abc.php");
$db = new abc();

$tj = " 1=1 ";
if(!empty($_GET["name"]))
{  
    $n = $_GET["name"];
   $tj = " name like '%{$n}%' ";
}

$ztj= "where {$tj}";
$sall="select count(*) from nation ".$ztj;
$zts=$db->StrQuery($sall);



include("../page.class.php");
$page = new Page($zts,5);


$sql = "select * from nation ".$ztj.$page->limit;
$arr = $db->Query($sql);

$smarty->assign("fenye",$page->fpage());
$smarty->assign("shuju",$arr);
$smarty->display("main.html");

基本运行成功
