Smarty s02

保留變量  方便使用php

                   不用assign

                   {$smarty}

                   get

                            {$smarty.get.page}

                   session

                            {$smarty.session.user.name}

                   server

                   cookies

                   request

                   const(常量)

 

 

         變量調節器

                   escape(跟php中的htmlentities())

                            $smarty->assign('title','<h3>標題</h3>')

                            {$title}則直接輸出 html的格式

                            {$title|escape}         轉碼

                            escape($title)

 

                   default

                   當沒有的時候則是默認值

        

                   date_format

                            {$smarty.now|date_format:"Y-m-d H:i:s"}

 

                   truncate(截取長度)

                            {"標題標題"|truncate:8}

 

                   upper(轉大寫)

                            {"lamp"|upper}

 

                   strtoupper

                            {"lamp"|strtoupper}

 

                   {"="|str_repeat:40}        

 

                   php中的函數能夠直接做爲變量調節器使用

                   自定義函數也能夠

 

 

         內置函數

                   foreach

                            {foreach $stulist as $stu}

                                     <tr>

                                               <td>{$stu@index+1}</td>

                                               <td>{$stu.name}</td>

                                     </tr>

                            {/foreach}        

                   if elseif else

                   while

                   include

                   for

                            (0-100的偶數)

                            {for $i=1 to 100 step 2}

                                      {i}

                            {/for}        

 

A.     Smarty配置

        

                   定義定界符(屬性)

                            $left_delimiter[左定界符]

                            $right_delimiter[右定界符]

                           

                            $smarty->left_delimiter='<{';

                            $smarty->right_delimiter='}>';

 

                   定義模版目錄

                            $template_dir[模板目錄]

 

                            $smarty->template_dir='./view';//屬性

                            $smarty->setTemplateDir('./view');//方法

                  

                   定義編譯的目錄

                            $smarty->setCompileDir('./view_c');

                            編譯目錄不存在則本身建立

 

                   緩存目錄

                            $smarty->setCachrDir('./cache')     ;

 

                   配置文件的目錄

                            $smarty->setConfigDir('./config');

 

B.     Smarty緩存

                   $smarty->conpile_check  [編譯檢查]

                   $smarty->conpile_compile  [強制編譯]

 

                   1.開啓緩存

                   $caching

                   $smarty->caching=1;      

 

 

                   接受參數

                   $id=intval($_GET['id'])l

                   //判斷緩存是否有效,把文章ID做爲緩存ID

                   //同一個模版,就能夠有多個緩存文件

                   if(!smarty->isCached('article.tpl',$id)){

                            $data=array(

                                     2=>array('id'=>2,'title')

                            )

                   }

 

 

                   2.緩存時間

                   $smarty->cache_lifetime=50  //秒錶 默認是3600      

 

                   3.//判斷是否有緩存

                   if(!$smarty->isCached('1.tpl')){

                            //有多是從數據庫查詢

                            //分配變量

                            $smarty->assign('title','標題')

                            //當前時間

                            $smarty->assign('now',date('Y-m-d H:i:s'));

                   }

                  

                   4.$smarty->display('article.tpl',$id)

 

                   不想緩存的地方

                   {nocache}

                            {$smarty.now|date_format}

                   {/nocache}

 

                   //清除某一個模版的緩存

                   $smarty->clearCache('article.tpl')

                   //清除某一個模版的ID的緩存

                   $smarty->clearCache('article.tpl',2)

 

                  

C.     Smarty插件

                   第一種方法

                   //將自定義函數註冊爲變量調節器

                   //第一個參數是插件的類型(9種)

                   //第二個參數是在Smarty中使用的名字

                   //第三個參數是咱們自定義的函數名字

                   $smarty->registerPlugin('modifier','wanghaoyu',myfun)

 

                   第二種方法

                   //添加一個插件目錄

                   //將特定命名的插件放到目錄中

                   //規則:類型前綴.函數名.php(9中類型前綴)

                   $smarty->addPluginDir('./myPlugins')

                   自定義函數的 smarty_modifier_前綴不能改

 

 

 

D.     Smarty繼承    extends

                   display('index.html')

                   在index代碼中寫上

                            {extends 'base.html'}

                            {block name='main'}

                                     <div>

                                               index的內容

                                     </div>

                            {/block}

                   在base.html想改的區域

                            {block name='main'}

 

                            {/block}

                   惟一能作的就是重寫某一塊

 

                   2.在block裏面追加內容

                   {block name='top' append}

                            <div>haha</div>

                   {/block}

 

                   3.某個部分的背景變色,當內容變的時候同時變

                   {block name='top'}  

                            <div class='top'>

                                     {$smarty.block.parent}

                            </div>

                   {/block}    

 

                   4.title

                   模版

                   {block name='head'}

                            <head>

                                     <title>{$smarty.block.child}</title>

                            </head>  

                   {/block}    

                  

                   顯示頁

                   {block name='head'}文章{/block}
