Smarty实例教学 实例篇

再来看看新闻页吧

=============================================================
news.php
=============================================================
<?php
/*********************************************

* 文件名： news.php
* 作 用： 新闻显示程序

*********************************************/
include_once("./comm/mySmarty.class.php"); //包含smarty的扩展类文件
include_once("./comm/adodb/adodb.inc.php"); //包含ADODB主执行文件

$smarty = new MySmarty(); //建立smarty实例对象$smarty

$conn = ADONewConnection("mysql"); //初始化ADODB
$conn->Connect("localhost", "root", "", "News"); //连接数据库

$NewsID = $_GET["id"]; //获取新闻编号
$NewsType = $_GET["type"]; //要显示的新闻类型
switch($NewsType)
{
case 1:
$dbName = "tb_news_CH";
break;
case 2:
$dbName = "tb_news_IN";
break;
case 3:
$dbName = "tb_news_MU";
break;
}

$strQuery = "SELECT vcNewsTitle AS NewsTitle, ltNewsContent AS NewsContent FROM " . $dbName;
1. $row = &$conn->GetRow($strQuery); //返回一个一维数组,下标为模板变量名

$smarty->display($row);
unset($row);

$conn->Close();
?>
=============================================================
说明一下关键的地方,其实在news.php中也只有一个地方值的说明一下了.

1. $conn->GetRow($strQuery):这一句返回一个一维数组,返回的形式为:

$array = ("NewsTitle"=>"xxxx", "NewsContent"=>"yyyyy...")
明白如果使用$smarty($array)后Smarty会干什么吗?对了,就是相当于:
$smarty->assign("NewsTitle", "xxxx");
$smarty->assign("NewsContent", "yyyyy...");

简单吧,确实很简单

下面再来看看新闻列表:
================================================================
newsList.php
================================================================
<?php

include_once("./comm/mySmarty.class.php"); //包含smarty的扩展类文件
include_once("./comm/adodb/adodb.inc.php"); //包含ADODB主执行文件

$smarty = new MySmarty(); //建立smarty实例对象$smarty

$conn = ADONewConnection("mysql"); //初始化ADODB
$conn->Connect("localhost", "root", "", "News"); //连接数据库

$NewsID = $_GET["id"]; //获取新闻编号
$NewsType = $_GET["type"]; //要显示的新闻类型
switch($NewsType)
{
case 1:
$tbName = "tb_news_CH";
break;
case 2:
$tbName = "tb_news_IN";
break;
case 3:
$tbName = "tb_news_MU";
break;
}

$strQuery = "SELECT iNewsID AS NewsID, vcNewsTitle AS NewsTitle FROM " . $tbName;
