Variables loaded from config files
从配置文件读取的变量
Variables that are loaded from the config files are referenced by enclosing
them within hash marks (#), or with the smarty variable $smarty.config.
The second syntax is useful for embedding into quoted attribute values.
配置文件中的变量需要通过用两个"#"或者是smarty的保留变量 $smarty.config.来调用(下节将讲到)
第二种语法在变量作为属性值并被引号括住的时候非常有用.
(译注:举个例子
{include file="#includefile#"} 这样#includefile#将被当作字符处理,而不表示配置文件变量,
但可以这样表示 {include file="`$smarty.config.includefile`"}不要忘了加``)
Example 4-5. config variables |
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: (alternate syntax) {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> OUTPUT: (same for both examples) <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> |
Config file variables cannot be used until after they are loaded in from a config file. This procedure is explained later in this document under {config_load}.
配置文件的变量只有在它们被加载以后才能使用.
这个过程将在以后
{config_load}. 的章节里说明.
