smarty模板引擎中变量及变量修饰器用法实例
本文实例讲述了smarty变量及变量修饰器的应用。分享给大家供大家参考。具体如下：
模板文件：temp.htm：
{$name.na1|cat:$name['na2']}
{$name['na1']|cat:'与'|cat:$name.na2}
{foreach from=$name item=na}
{$na}
{/foreach}
{$dog->leee()}{$dog->name}
<script>
{literal}
function foobar{
alert('foobar!');
}
{/literal}
</script>
<title>{#pagetitle#}</title>
<body bgcolor="{#bodybgcolor#}">
<table border="{#tablebordersize#}" bgcolor="{#tablebgcolor#}" >
<tr bgcolor="{#rowbgcolor#}">
<td>dosomething</td>
<td>帅锅</td>
</tr>
</table>
{$smarty.server.server_name}
<hr />
{$str|count_words}
<hr />
-------常量--------<br>
{$smarty.now}<br />{$smarty.const.my_const}<br />{$smarty.template}<br />{$smarty.current_dir}<br />{$smarty.version}<br />{$smarty.ldelim|cat:$smarty.rdelim}
<hr />
{$smarty.now|date_format:$config}
{$yesterday|date_format:'y-m-d'}
<hr />
{$string|default:'default变量修饰：smarty学习'}
<hr />
{$str1|escape:'html'}<br />{$str2|escape:'mail'}
<hr />
<p>{$str1|indent|upper}</p>
{$str1|nl2br}
<hr />
{$str1|regex_replace:"/@\d{3}/":"abc"}<br />
{$str1|replace:"163":"sina"}<br />
{$str1|spacify}<br />
<hr />
{$number|string_format:"%.2f"}<br />
{$number|string_format:"%d"}<br />
<hr />
{$str3|strip:"|"}<br />
去除包含在<>之间的字符：{$str3|strip_tags}<br />
截取长度：{$str3|truncate:10:"...":true}<br />
按长度换行：{$str3|wordwrap:30:"<br />"}
<hr />
{append var='name' value="bob" index="first"}
{append var='name' value="john" index="last"}
{$name.last}<br />
{foreach from=$family item=home}
{foreach from=$home item=person}
{$person}
{/foreach}
{/foreach}
{$family[1].girl}
<hr />
{assign var="name" value="张三丰"}
{$name}
