Smarty变量用法详解,smarty变量详解
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.
