初来乍到--------smarty

Smarty

 

Day01-----smarty的使用
作用:把php+html分离,程序和美工
使用:
1、下载源码包
2、目录结构
libs
源码文件
Smarty.class.php
template //模板文件 html文件
template_c //程序运行过程中,自动产生的,模板编译文件
3、实例化
require "Smarty.class.php";
$smartyOb=new Smarty();
4、配置
告诉Smarty哪个目录是放模板html的
$smartyOb->setTemplateDir(path);
告诉smarty哪个目录是放编译文件的
$smartyOb->setCompileDir(path)
5、显示模板
$smartyOb->display("模板名称及路径");
如何给模板传值
$smartyOb->assign('模板上名称',被传递的变量);
在模板上如何调用
模板标签
{$名称}
数组
{$数组名.下标}
二维数组
array(
0=>array('title'=>'t1','pubtime'=>1234567890,'author'=>'xiaoli'),
1=>array('title'=>'t2','pubtime'=>1334567890,'author'=>'xiaoli'),
array('title'=>'t3','pubtime'=>1434567890,'author'=>'xiaoli'),
array('title'=>'t4','pubtime'=>1534567890,'author'=>'xiaoli'),
)
遍历数组
{foreach 数组名 as 变量名}
{$变量名.title}
{/foreach}
下标值

循环次数

当前是第几次循环

是否为第一次循环

是否为最后一次循环

案例:
实现一个隔行背景颜色变化

代码

练习:
给每个li加上下划线(虚线),最后一行除外

了解内容:



属性:





练习:
使用section,实现隔行背景颜色不一样

变量调节器

模板标签定界符的指定:

$smartyOb->left_delimiter=" $smartyOb->right_delimiter="}>";

day02---------,回顾day01的内容,扩充新知识

Smarty
1、Smarty,放在php主程序中
2、配置
$smartyOb->setTemplateDir()
$smartyOb->setCompileDir()
$smartyOb->left_delimiter()
$smartyOb->right_delimiter()
3、给模板传值
$smartyOb->assign("模板变量名称",变量);
4、显示模板
$smartyOb->display(path);

{$名称}
{$数组.下标}
{foreach 数组名 as 变量}
{$变量名}
{/foreach}
标签属性:
[email protected]}
[email protected]}
[email protected]}
[email protected]}
[email protected]}
[email protected]}
{if 条件}
{else}
{/if}

变量调节器:
{第一个参数|函数名:第二个参数:.......}
文章详细页:
02_detail.php?id=5
1、配置smarty
2、接收文章id
3、实例化pdo
4、拼sql语句
5、执行
6、获取数据
7、给模板传值
8、显示模板
9、套模板标签,使用主程序传递过来的数据

页面拆分
{include file="模板的路径"}
注册函数
function fun1(){
return 'abc';
}
$smartyOb->registerPlugin("function","模板函数名","被注册的函数名称");

在模板上调用:
{模板函数名称 名=值 名=值 ....}
如何传参???
1、参数个数最多两个,
第一个接收的模板上所有的传参,
第二参数接收的是当前的smarty对象。
缓存
数据库中的数据被缓存。
好处:减轻了mysql服务器的压力
1、指定缓存文件的存放目录
$smartyOb->setCacheDir(ROOT."day02/cache");
2、开启缓存
$smartyOb->caching=true;
3、指定缓存的生命周期。
$smartyOb->cache_lifetime=100;//秒
作用:判断缓存文件是否存在且有效
$smartyOb->isCached("模板名称及路径",id)
$smartyOb->display("模板名称及路径",id);
