常量和CodeIgniter [英] Constants and CodeIgniter

问题描述

CodeIgniter中的常量可以用于整个站点中的重复文本(例如重复标记和元描述)吗?像这样:

Can constants in CodeIgniter be used for things like recurring text (say metatags and meta-descriptions) throughout the site? Something like:

define('METADESCRIPTION', 'This is my site');

然后将METADESCRIPTION回显到meta标签中?

and then echo METADESCRIPTION into the meta tags?

<meta name="description" content="<?php echo METADESCRIPTION; ?>"> 

推荐答案

是.

要访问整个应用程序，您可以在config.php甚至index.php文件中定义常量.

For access throughout the app you can define constants in config.php or even in index.php files.

config.php或index.php

config.php or in index.php

define('METADESCRIPTION', 'This is my site'); 

在您的控制器或视图上.

on your controllers or views.

确定

$myVar = METADESCRIPTION; 

或访问

echo METADESCRIPTION;
