Codeigniter: Variables/Config Items within Language Files

Question

I have a language file with a long list of strings for my view files. My question is how to pass a variable or a config item to a language file?

<?php $lang['error_activation_key_expired'] = 'The activation key you have attempted using has expired. Please request a new Activation Key <a href="'.$this->config->item('base_url').'member/request_activation" title="Request a New Activation Key">here</a>.';

I would could settle for

<?php $lang['error_activation_key_expired'] = 'The activation key you have attempted using has expired. Please request a new Activation Key <a href="'.$base_url.'member/request_activation" title="Request a New Activation Key">here</a>.';

and pass the base_url to it somehow. I just don't know how.

Thanks!

Your best bet is probably to put a placeholder in there, then swap it out in your controller.

Lang file:

<?php $lang['error_activation_key_expired'] = 'The activation key you have attempted using has expired. Please request a new Activation Key <a href="%s/member/request_activation" title="Request a New Activation Key">here</a>.';

In controller:

$activation_message = sprintf($this->lang->line('error_activation_key_expired'), $base_url);
