smarty使用

smarty—牛刀小试

###smarty 初识
- 官网 http://www.smarty.net/
- Smarty is a template engine for PHP(PHP模板引擎)

smarty使用：

---

index.php

    <?php
    date_default_timezone_set("PRC");//PRC为“中华人民共和国”
	require ('../smarty/Smarty.class.php');
	$smarty = new Smarty();

	/*Smarty配置（五配置两方法）2.0版本*/
	// $smarty->left_delimiter = "{";   //左定界符
	// $smarty->right_delimiter = "}";  //右定界符
	// $smarty->template_dir = "tpl";   //html模板地址
	// $smarty->compile_dir = "template_c"; //模板编生成的文件
	// $smarty->cache_dir = "cache";  //缓存
	//以下是开启缓存的另外两个配置。因为一般不用smarty的配置，这里作为了解
	$smarty->caching = true; //开启缓存
	$smarty->cache_lifetime = 120; //缓存时间

	/*smarty3.0版本后的五配置*/
	$smarty->setLeftDelimiter('{');//左定界符
	$smarty->setRightDelimiter('}');//右定界符
	$smarty->setTemplateDir('tpl/');//模板地址
	$smarty->setCompileDir('template_c/');//编译文件
	$smarty->setCacheDir('cache/');//缓存地址
	$smarty->assign('articalTitle','奔波霸');
	$smarty->display('test.tpl');
	?>

test.tpl

  {$articalTitle};

smarty 输出数组

---

$arr = array("title"=>"lol","name"=>"德玛西亚");
$smarty->assign("arr", $arr);
$brr = array("artical"=>array("title"=>"lol","name"=>"德玛西亚"));
$smarty->assign("brr", $brr);

{$arr['title']}{$arr['name']};     {*一维数组*}{*注释*}
{$brr["artical"]["title"]}{$brr["artical"]["name"]} {*二维数组*}

smarty 注释

---

{* XXX *}

smarty 变量调节器

---

####capitalize,cat,upper,lower

$scale = "hello";
$smarty->assign("scale", $scale);

{$scale|capitalize};   {*首字母大写*}
{$scale|cat:" kity"}   {*连接字符串*}
{$scale|upper};       {*大写变量调节器*}
{$scale|lower|upper}; {*小写变量调节器*}

date_format

$time = time();
$smarty->assign("time", $time);

{$time|date_format:"%B %e,%y %H:%M:%S"}; {*日期格式化*}

default

$lol = "";
$smarty->assign("lol", $lol);

{$lol|default:"诺克萨斯之手"}  {*默认输出*}

escape

$url = "https://www.baidu.com";
$smarty->assign("url", $url);

{$url|escape:"url"} {*url转码*}

nl2br

$str = "我有一只小毛驴\n从来也不骑";
$smarty->assign("str", $str);

{$str|nl2br}          {*换行符转换为br,html不识别\n,其中2(two)是to的谐音*}

smarty 对象赋值

class Cool {
		function dd(){
			echo "pilipala";
		}
	}
	$obj = new Cool();
	$smarty->assign("obj",$obj);

{$obj->dd()}

smarty 函数使用

function add ($params){           //$params为模板传递过来的数组变量
      $p1 = $params["p1"];
      $p2 = $params["p2"];
      echo $p1."已经".$p2;
	}
$smarty->registerPlugin("function", "f_test", "add");     //f_test为函数名字便于模板调用，add为函数本身

{f_test p1="苹果" p2="熟了"}      {*将后面的键值对组合为数组，作为参数传递给函数本身*}

smarty 使用php的变量调节器

smarty->assign("time", time());
$str = "我有一只小毛驴\n从来也不骑";
$smarty->assign("str", $str);

{"Y-m-d"|date:$time}           {*此处$time对应前面time，date调节器第一个参数为格式，第二个参数为日期*}
{"小"|str_replace:"大":$str}   {*str_replace调节器，第一个参数为替换谁，第二个参数为替换为什么，第三个参数为被替换的字符串*}

smarty 编写插件

---

####function插件
plugins目录下新建function.插件名.php

如：function.test.php

function.test.php

<?php
function smarty_function_test($params){
	$p1 = $params["p1"];
    $p2 = $params["p2"];
    echo $p1."已经".$p2;
}
?>

test.tpl

{test p1="苹果" p2="熟了"}

modeifier插件(变量调节器插件)

block插件(区块函数插件)

smarty 循环

---

$crr = array(array("title"=>"lol","name"=>"德玛西亚"));
$smarty->assign("crr", $crr);

{foreach $crr as $value}
 {$value.title}
 {$value.name}
{foreachelse}
没有
{/foreach}
