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:
1
2
3
4
|
$smarty = new Smarty; $smarty ->assign( 'firstname' , 'Doug' ); $smarty ->assign( 'lastLoginDate' , 'January11th, 2001' ); $smarty ->display( 'index.tpl' ); |
index.tpl:
1
2
3
|
Hello {$firstname}, glad to see you couldmake it. < p > Your last login was on {$lastLoginDate}. |
输出:
1
2
3
|
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:
1
2
3
4
5
|
pageTitle = "This is mine" bodyBgColor = "#eeeeee" tableBorderSize = "3" tableBgColor = "#bbbbbb" rowBgColor = "#cccccc" |
index.tpl:
1
2
3
4
5
6
7
8
9
10
11
12
13
|
{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:
1
2
3
4
5
6
7
8
9
10
11
12
13
|
{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:
1
2
3
4
5
6
7
8
9
10
11
12
|
< 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.
希望本文所述对大家基于smarty模板的PHP程序设计有所帮助。
