1.配置

        define("ROOTPATH",dirname(__FILE__)."/../");
        require_once("smarty/Smarty.class.php");

        /**
         * Smarty Template Class Initializtion
         */
        if( @constant( "ENABLED_TPL" ) ) {
            $obj_smarty = new Smarty();
            $obj_smarty->compile_check = true; //Open Compile Check
            $obj_smarty->debugging = false;// false || DEBUG || DEBUG_TPL; //debug On-off
            $obj_smarty->template_dir = ROOT_PATH."html"; //Set Template Document Root
            $obj_smarty->compile_dir = ROOT_PATH."cache"; //Set Template Cache File Document Root
            $obj_smarty->left_delimiter = "<!!"; //Set Template Left Delimiter
            $obj_smarty->right_delimiter = "!!>"; //Set Template Right Delimiter
            /**
             * 0：Smarty默認值，表示不對模板進行緩存 
             * 1：表示Smarty將使用當前定義的cache_lifetime來決定是否結束cache
             * 2：表示Smarty將使用在cache被創建時使用cache_lifetime這個值
             * 習慣上使用true與false來表示是否進行緩存
             */
            $obj_smarty->caching = true;
            $obj_smarty->cache_lifetime = 60 * 60 * 24;//-1:緩存從不過時,0:每次執行緩存老是被從新創建 
        } 


2.循環,section,sectionelse

        <!!sectionelse!!> 用來表示傳入的數組變量爲空時對模板進行的處理。

        <!!section name=one loop=$arr_result start=5 step=2 max=3 show=$show_customer_info!!> 
           <!!$arr_result[one].name!!> 
           <!!$smarty.section.one.iteration!!> //display the current loop iteration
           <!!$smarty.section.one.index!!>     //display the current loop index, starting with zero 
           <!!$smarty.section.one.first!!>     //first is set to true if the current section iteration is the first one
           <!!$smarty.section.one.last!!>      //last is set to true if the current section iteration is the last one. 
           <!!$smarty.section.one.loop!!>      //display the last index number that this section looped
           <!!$smarty.section.one.show!!>      //show is a boolean value, true or false
           <!!$smarty.section.one.total!!>     //display the number of iterations that this section will loop      
           <!!$smarty.section.name.rownum+$offset!!>//display the current loop iteration, starting with one $offset爲基值
        <!!/section!!>


        <!!section name=one loop=$arr_result!!>
            <input type="checkbox" name="<!!$name!!>[]" id="<!!$name!!>_<!!$smarty.section.one.index+1!!>" value="<!!$arr_result[one].value!!>" 
            <!!if ($arr_result[one].value|inarray:$arr_values) !!>checked<!!/if!!>/><!!$arr_result[one].value!!>
        <!!/section!!> 

        <!!section name=one loop=$arr_result!!>
            <option value="<!!$arr_result[opt].value!!>" <!!if $arr_result[one].value==$selectedvalue !!>selected<!!/if!!>><!!$arr_result[one].option!!></option>
        <!!/section!!>


        表格排版 1行2列 
                <!!if $smarty.section.one.index%2 eq 0 !!>
                <!!if $smarty.section.one.index%2 eq 1 !!>

        奇偶數用於斑馬線效果
                <!!if $smarty.section.one.rownum%2 eq '0'!!>...<!!else!!>...<!!/if!!>

        生成斑馬線
                <div style="background:<!!cycle values='#F0F8FF,#F0FFFF,#FFFAF0,#F0FFF0'!!>" id="div_msg_<!!$smarty.section.one.rownum!!>">
                ...

                time="2006-06-06" 能夠給定輸出想要的值


12:循環,foreach,foreachelse

        選擇性的section循環
                from 須要循環的數組的名稱 
                item 當前元素的變量名 
                key   當前關鍵字的變量名
                name 訪問foreache屬性的foreach循環名

                $smarty->assign("arr_result", array(array("phone" => "1", "fax" => "2", "cell" => "3"),
                        array("phone" => "555-4444", "fax" => "555-3333", "cell" => "760-1234")));

19:獲取字符串,fetch

        獲取字符串
                $str_html = $obj_smarty->fetch("index.html");


20:capture

        capture函數的做用是收集模板輸出的數據到一個變量裏,而不是把它們輸出到頁面.
        任何在 {capture name="foo"}和{/capture}之間的數據都被收到了由函數的名稱屬性指定的變量裏($foo).
        收集的信息能夠用在特殊變量$smarty裏.
        例如capture.foo就收集了以上數據.若是函數沒有名字屬性,將使用"default".
        每一個{capture}都必須對應{/capture},也不能嵌套使用capture函數
        {capture name=banner}
            1
        {/capture}
        {capture name=banner2}
            2
        {/capture}

        {if $smarty.capture.banner ne ""}
            <tr>
                <td>
                    {$smarty.capture.banner}
                </td>
                <td>
                    {$smarty.capture.banner2}
                </td>
            </tr>
        {/if}
        抓取數據存放在變量中 能夠在一個頁面中重複使用


21:include_php,php

        include_php
                在模板里加載php文件
        php
                能夠直接使用php代碼 至關於<?php     ?>
        <!!include_php file="phpinfo.php"!!>
        <!!php!!>
            include("phpinfo.php");
            echo date("h:i:s");
        <!!/php!!>


22:insert

        使模板的一部分不被緩存
        //demo.php
                $int_cache_id = sprintf('%X', crc32("index.html"));
                if( !$obj_smarty->is_cached('index.html', $int_cache_id) ) {
                    $obj_smarty->assign("str_date",date("h:i:s"));
                }
                $obj_smarty->display("index.html",$int_cache_id);

                function insert_getBanner( $arrParams ) {
                    return $arrParams["lid"]."-andy-".$arrParams["sid"];
                }

        //index.html
                <!!$str_date!!>
                <!!insert name="getBanner" lid="1" sid="2" !!>


23:ldelim,rdelim

        ldelim and rdelim are used for displaying the literal delimiter, in our case "{" or "}". 
        輸出變量 不作解析 
                <!!ldelim!!>funcname<!!rdelim!!> is how functions look in Smarty!
        OUTPUT:
                <!!funcname!!> is how functions look in Smarty!


24:strip

        去除<!!strip}<!!/strip!!>間的全部空格


25:{$smarty}保留變量

        頁面請求變量
        {* display value of page from URL (GET) http://www.domain.com/index.php?page=foo *}
        {$smarty.get.page}

        {* display the variable "page" from a form a form (POST) *}
        {$smarty.post.page}

        {* display the value of the cookie "username" *}
        {$smarty.cookies.username}

        {* display the server variable "SERVER_NAME" *}
        {$smarty.server.SERVER_NAME}

        {* display the system environment variable "PATH" *}
        {$smarty.env.PATH}

        {* display the php session variable "id" *}
        {$smarty.session.id}

        {* display the variable "username" from merged get/post/cookies/server/env *}
        {$smarty.request.username}

        {$smarty.now}變量用於訪問 當前時間戳.

        能夠用 date_format調節器格式化輸出.
        {* use the date_format modifier to show current date and time *}
        {$smarty.now|date_format:"%Y-%m-%d %H:%M:%S"}

        {$smarty.const}
        能夠直接訪問PHP常量.
        {$smarty.const._MY_CONST_VAL}

        {$smarty.template}
        當前被處理的模板的名字


26:組合使用調節器 |
       
        <!!$articleTitle!!>
        <!!$articleTitle|upper|spacify!!>
        <!!$articleTitle|lower|spacify|truncate!!>
        <!!$articleTitle|lower|truncate:30|spacify!!>
        <!!$articleTitle|lower|spacify|truncate:30:". . ."!!>


27:fetch

        抓取數據
                {* include some javascript in your template *}
                {fetch file="/export/httpd/www.domain.com/docs/navbar.js"}

                {* embed some weather text in your template from another web site *}
                {fetch file="http://www.myweather.com/68502/"}

                {* fetch a news headline file via ftp *}
                {fetch file="ftp://user:password@ftp.domain.com/path/to/currentheadlines.txt"}

                {* assign the fetched contents to a template variable *}
                {fetch file="http://www.myweather.com/68502/" assign="weather"}
                {if $weather ne ""}
                    {$weather}
                {/if}
