Question

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');

and then echo METADESCRIPTION into the meta tags?

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

Answer 1

Yes.

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

config.php or in index.php

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

on your controllers or views.

assing

$myVar = METADESCRIPTION; 

or access

echo METADESCRIPTION;
