smarty模板引擎从php中获取数据的方法
这篇文章主要介绍了smarty模板引擎从php中获取数据的方法,涉及smarty变量与php代码的混编技巧,具有一定参考借鉴价值,需要的朋友可以参考下
本文实例讲述了smarty模板引擎从php中获取数据的方法。分享给大家供大家参考。具体如下:
smarty可以分配($smarty->assign)的变量类型:所有php支持的数据类型——基本数据类型、复合数据类型、特殊数据类型(具体见smarty相关手册)。
操作/显示文件:index.php
- <?php
- //创建smarty对象
- require_once("./libs/Smarty.class.php");
- $smarty = new Smarty();
- $smarty->assign("aa","hello word");//分配字符串
- $smarty->assign("bb",123);//分配整型
- $smarty->assign("cc",90.8);//分配float型,浮点型
- $smarty->assign("dd",true);//分配字符串
- //分配数组,数组一般从数据库取出,这里直接给数组
- $arr1 = array("北京","上海","广州");//索引数组
- $smarty->assign("arr1",$arr1);//分配索引数组
- $arr2 = array("city1"=>"北京","city2"=>"上海","city3"=>"广州");//关联数组
- $smarty->assign("arr2",$arr2);//分配关联数组
- $arr3 = array(array("北京","上海","广州"),array("关羽","张飞","美女"));
- $smarty->assign("arr3",$arr3);
- $arr4 = array("aa"=>array("北京","上海","广州"),"bb"=>array("关羽","张飞","美女"));
- $smarty->assign("arr4",$arr4);
- //对象类型
- class Master{
- public $name;
- public $address;
- }
- $master = new Master();
- $master->name="百度";
- $master->address = "中关村";
- class Dog{
- public $name;
- public $age;
- public $color;
- public $arr;
- public $master;
- function __construct($name,$age,$color,$arr){
- $this->name = $name;
- $this->age = $age;
- $this->color = $color;
- $this->arr = $arr;
- }
- }
- $dog = new Dog("小狗",4,"金黄色",$arr2);
- $dog->master = $master;
- $smarty->assign("dog",$dog);
- $smarty->display("index.tpl");
- ?>
模板文件:index.tpl 代码如下:
- <html>
- <h2>smarty变量操作</h2>
- <p >取字符串:{$aa}</p>
- <p >取整数:{$bb}</p>
- <p >取浮点型:{$cc}</p>
- <p >取布尔值:{$dd}</p>
- <p >取数组(索引数组):{$arr1[0]}--{$arr1[1]}--{$arr1[2]}</p>
- <p >取数组(关联数组):{$arr2.city1}--{$arr2.city2}--{$arr2.city3}</p>
- <p >取二组数组(索引,取单个):{$arr3[0][0]}</p>
- <p >取二组数组(索引,遍历全部):</p>
- <p >取二维数组(关联):{$arr4.aa[2]}</p>
- <p >取二维数组(关联、遍历):</p>
- <p >取对象(普通属性):{$dog->name}</p>
- <p >取对象(数组属性):{$dog->arr.city1}</p>
- <p >取对象(对象属性):{$dog->master->name}</p>
