smarty能夠實現HTML與php代碼的分離，以前咱們用php代碼作過數據的增刪改查，如今咱們運用smarty來實現這些功能，並用分頁顯示php

 

查詢;html

主頁面，以表格的形式顯示數據及須要的操做：one.htmlsql

複製代碼 
<body>
<h1>主頁面</h1>
<form action="one.php" method="get">
<div>題目名稱:
<input type="text" name="name" />
所屬科目：
<select name="km">
<{foreach $km as $v}>
    <option value="<{$v[0]}>"><{$v[1]}></option>
<{/foreach}>
</select>
<input type="submit" value="查詢" />
</div>
</form>
<table border="1" width="100%" cellpadding="0" cellspacing="0">
<tr>
    <td>題目名稱</td>
    <td>答案</td>
    <td>所屬科目</td>
    <td>難度</td>
    <td>類型</td>
    <td>操做</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="delete.php?code=<{$v[0]}>">刪除</a>
   <a href="update.php?code=<{$v[0]}>">修改</a></td>
</tr>
<{/foreach}>


</table>
<a href="add.php">添加數據</a>
<div><{$fpage}></div>
</body>
複製代碼

 

one.php：對one.html頁面進行控制，查找數據，傳送數據，並經過運行該頁面顯示one.html頁面內容；在該頁面實現分頁查詢數據庫

複製代碼 
<?php
include("../init.inc.php");
include("../../DBDA.class.php");
include("page.class.php");

$db = new DBDA();
//查科目
$skm = "select * from kemu";
$akm = $db->Query($skm);



//查詢條件
$tj = " 1=1 ";//題目
$tj2 = " 1=1 ";//科目
if(!empty($_GET["name"]))
{
    $tj = " name like '%{$_GET['name']}%' ";
}
if(!empty($_GET["km"]))
{
    $tj2 = " kemu = '{$_GET['km']}' ";
}
$ftj = " where".$tj." and".$tj2;//注意空格

//總數
$sqlz = "select count(*) from timu".$ftj;
$total = $db->StrQuery($sqlz);
$page = new Page($total,2);

//查詢數據實現分頁
$sql = "select * from timu".$ftj.$page->limit;
$attr = $db->Query($sql);

$fpage = $page->fpage();



$smarty->assign("km",$akm);
$smarty->assign("fpage",$fpage);
$smarty->assign("shuju",$attr);
$smarty->display("one.html");
