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。
