Smarty 中所有的访问都是基于变量的,下面通过一个实例来进行说明。
实例思路:主文件通过引入模板初始化配置文件(init.inc.php)和一个类,并对模板中的变量进行赋值显示。
首先,设置init.inc.php 文件,作为Smarty 模板的初始化配置文件
init.inc.php
define('ROOT_PATH', dirname(__FILE__)); //定义网站根目录
require ROOT_PATH.'/libs/Smarty.class.php'; //载入Smarty 文件
$_tpl = new Smarty(); //实例化一个对象
$_tpl->template_dir = ROOT_PATH.'/tpl/'; //重新设置模板目录为根目录下的tpl 目录
$_tpl->compile_dir = ROOT_PATH.'./com/'; //重新设置编译目录为根目录下的com 目录
$_tpl->left_delimiter = '
$_tpl->right_delimiter = '}>'; //重新设置左定界符为'}>'
?>
主文件index.php
require 'init.inc.php'; //引入模板初始化文件
require 'Persion.class.php'; //载入对象文件
global $_tpl;
$title = 'This is a title!';
$content = 'This is body content!';
/*
* 一、从PHP 中分配给模板变量;
* 动态的数据(PHP从数据库或文件,以及算法生成的变量)
* 任何类型的数据都可以从PHP分配过来,主要包括如下
* 标量:string、int、double、boolean
* 复合:array、object
* NULL
* 索引数组是直接通过索引来访问的
* 关联数组,不是使用[关联下标]而是使用. 下标的方式
* 对象是直接通过->来访问的
* */
$_tpl->assign('title',$title);
$_tpl->assign('content',$content); //变量的赋值
$_tpl->assign('arr1',array('abc','def','ghi')); //索引数组的赋值
$_tpl->assign('arr2',array(array('abc','def','ghi'),array('jkl','mno','pqr'))); //索引二维数组的赋值
$_tpl->assign('arr3',array('one'=>'111','two'=>'222','three'=>'333')); //关联数组的赋值
$_tpl->assign('arr4',array('one'=>array('one'=>'111','two'=>'222'),'two'=>array('three'=>'333','four'=>'444'))); //关联二维数组的赋值
$_tpl->assign('arr5',array('one'=>array('111','222'),array('three'=>'333','444'))); //关联和索引混合数组的赋值
$_tpl->assign('object',new Persion('小易', 10)); //对象赋值
//Smarty 中数值也可以进行运算(+-*/^……)
$_tpl->assign('num1',10);
$_tpl->assign('num2',20);
$_tpl->display('index.tpl');
?>
主文件index.php 的模板文件index.tpl(搁置在/tpl/目录下)

变量的访问:
索引数组的访问:
索引二维数组的访问:
关联数组的访问:
关联二维数组的访问:
关联和索引混合数组的访问:
对象中成员变量的访问:name}> age}>
对象中方法的访问:hello()}>
变量的运算:
变量的混合运算:
Persion.class.php
class Persion {
public $name; //为了访问方便,设定为public
public $age;
//定义一个构造方法
public function __construct($name,$age) {
$this->name = $name;
$this->age = $age;
}
//定义一个hello() 方法,输出名字和年龄
public function hello() {
return '您好!我叫'.$this->name.',今年'.$this->age.'岁了。';
}
}
?>
执行结果:
变量的访问:This is body content!
索引数组的访问:abc def ghi
索引二维数组的访问:abc def ghi jkl mno pqr
关联数组的访问:111 222 333
关联二维数组的访问:111 222 333 444
关联和索引混合数组的访问:111 222 333 444
对象中成员变量的访问:小易10
对象中方法的访问:您好!我叫小易,今年10岁了。
变量的运算:30
变量的混合运算:94
