Smarty变量用法详解_php实例
本文实例讲述了Smarty变量用法。分享给大家供大家参考，具体如下：
1. 从PHP分配的变量
调用从PHP分配的变量需在前加"$"符号.（译注：同php一样）
调用模板内的assign函数分配的变量也是这样.（译注：也是用$加变量名来调用）
示例:
index.php:
$smarty = new Smarty;
$smarty->assign('firstname', 'Doug');
$smarty->assign('lastLoginDate', 'January11th, 2001');
$smarty->display('index.tpl');
index.tpl:
Hello {$firstname}, glad to see you couldmake it.
<p>
Your last login was on {$lastLoginDate}.
输出:
Hello Doug, glad to see you could make it. <p> Your last login was on January 11th, 2001.
2. 从配置文件读取的变量
配置文件中的变量需要通过用两个"#"或者是smarty的保留变量 $smarty.config.来调用（后面会讲到）
第二种语法在变量作为属性值并被引号括住的时候非常有用.
（译注：举个例子 {include file="#includefile#"} 这样#includefile#将被当作字符处理，而不表示配置文件变量，但可以这样表示{include file="`$smarty.config.includefile`"}不要忘了加``）
示例:
foo.conf:
pageTitle = "This is mine" bodyBgColor = "#eeeeee" tableBorderSize = "3" tableBgColor = "#bbbbbb" rowBgColor = "#cccccc"
index.tpl:
{config_load file="foo.conf"}
<html>
<title>{#pageTitle#}</title>
<body bgcolor="{#bodyBgColor#}">
<table border="{#tableBorderSize#}" bgcolor="{#tableBgColor#}">
<tr bgcolor="{#rowBgColor#}">
<td>First</td>
<td>Last</td>
<td>Address</td>
</tr>
</table>
</body>
</html>
index.tpl:
{config_load file="foo.conf"}
<html>
<title>{$smarty.config.pageTitle}</title>
<body bgcolor="{$smarty.config.bodyBgColor}">
<table border="{$smarty.config.tableBorderSize}"bgcolor="{$smarty.config.tableBgColor}">
<tr bgcolor="{$smarty.config.rowBgColor}">
<td>First</td>
<td>Last</td>
<td>Address</td>
</tr>
</table>
</body>
</html>
上述两种模板写法都输出:
<html>
<title>This is mine</title>
<body bgcolor="#eeeeee">
<table border="3" bgcolor="#bbbbbb">
<tr bgcolor="#cccccc">
<td>First</td>
<td>Last</td>
<td>Address</td>
</tr>
</table>
</body>
</html>
配置文件的变量只有在它们被加载以后才能使用.
