smarty变量调节器

1、capitalize[首字符大写]  调用方法：

<?php$smarty->assign('articleTitle', 'next x-men film, x3, delayed.');?>  
调用方法:
{$articleTitle}
{$articleTitle|capitalize}
{$articleTitle|capitalize:true}   
实现结果:
next x-men film, x3, delayed.
Next X-Men Film, x3, Delayed.
Next X-Men Film, X3, Delayed.

2、cat[连接字符串]

<?php$smarty->assign('articleTitle', "Psychics predict world didn't end");?>

调用方法:

{$articleTitle|cat:" yesterday."}

实现结果:

3、date_format[格式化日期]

<?php
$config['date'] = '%I:%M %p';
$config['time'] = '%H:%M:%S';
$smarty->assign('config', $config);
$smarty->assign('yesterday', strtotime('-1 day'));
?>

这个模板使用 $smarty.now 提取当前时间:
{$smarty.now|date_format}
{$smarty.now|date_format:"%D"}
{$smarty.now|date_format:$config.date}
{$yesterday|date_format}
{$yesterday|date_format:"%A, %B %e, %Y"}
{$yesterday|date_format:$config.time}
