php中smarty变量修饰用法实例分析

这篇文章主要介绍了php中smarty变量修饰用法,实例分析了smarty模板变量修饰的常用技巧,需要的朋友可以参考下。

本文实例讲述了php中smarty变量修饰用法,分享给大家供大家参考,具体实现方法如下:

test.php代码:

  1. <?php
  2. require 'libs/Smarty.class.php'; //包含Smarty类库文件
  3. $smarty = new Smarty; //创建一个新的Smarty对象
  4. $total = 12345; //对$total赋值
  5. $smarty->assign("total",$total); //对模版中的变量赋值
  6. $formatted_total = number_format($total); //格式化$total
  7. $smarty->assign("formatted_total",$formatted_total); //对模版中的变量赋值
  8. $smarty->display('test1.htm'); //显示页面
  9. ?>

test1.html模板代码:

  1. <html>
  2. <head>
  3. <title>Smarty Test</title>
  4. </head>
  5. <body>
  6. <H1>Total is {$total}</H1>
  7. <H1>Formatted Total is {$formatted_total}</H1>
  8. </body>
  9. </html>

编译后的test.html.php代码:

  1. <?php /* Smarty version 2.6.22, created on 2009-03-19 14:37:39
  2. compiled from test1.htm */ ?>
  3. <html>
  4. <head>
  5. <title>Smarty Test</title>
  6. </head>
  7. <body>
  8. <H1>Total is <?php echo $this->_tpl_vars['total']; ?>
  9. </H1>
  10. <H1>Formatted Total is <?php echo $this->_tpl_vars['formatted_total']; ?>
  11. </H1>
  12. </body>
  13. </html>

test1.html模板可以改写成这样test2.html:

  1. <html>
  2. <head>
  3. <title>Smarty Test</title>
  4. </head>
  5. <body>
  6. <H1>Total is {$total}</H1>
  7. <H1>Formatted Total is {$total|number_format}</H1>
  8. </body>
  9. </html>

则相应的test.php代码改为:

  1. <?php
  2. require 'libs/Smarty.class.php'; //包含Smarty类库文件
  3. $smarty = new Smarty; //创建一个新的Smarty对象
  4. $total = 12345;
  5. $smarty->assign("total",$total); //对模版中的变量赋值
  6. $smarty->display('test2.htm'); //显示页面
  7. ?>

浏览器显示:

Total is 12345

Formatted Total is 12,345
