smarty变量调节器如何使用

smarty变量调节器是用来改变显示的值，不改变变量的值。这里给大家总结了一下，希望对大家的smarty学习有参考意义。

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:

Psychics predict world didn’t end yesterday.

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}

运行结果:

Jan 1, 2022

01/01/22

02:33 pm

Dec 31, 2021

Monday, December 1, 2021

14:33:00

4、regex_replace[ 正则替换

<?php$smarty->assign("zhengze","hae2525ahwo3w");

将字符串中的数字换为QQ：<div><{$zhengze|regex_replace:"/\d/":"QQ"}></div>

运行结果：

haeQQQQQQQQahwoQQw

5、replace[替换

<?php$smarty->assign("tihuan","nice to meet you");

将字母e替换为#<div><{$tihuan}></div>

<div><{$tihuan|replace:"e":"#"}></div>

运行结果：

nice to meet you

nic# to m##t you

6、truncate[截取

<?php$smarty->assign("jiequ","welcome to zibo");

截取10个字符，句尾或句中显示2个*

<div><{$jiequ}></div>

<div><{$jiequ|truncate:1}></div>

<div><{$jiequ|truncate:10:"**"}></div>

<div><{$jiequ|truncate:10:"**":true}></div>

<div><{$jiequ|truncate:10:"**":true:true}></div>

运行结果：

welcome to zibo...

welcome**

welcome **

welc**zibo
