Canonical Tag set

I set it in a controller as a header variable:

PHP Code:

$header_data['canonical'] = 'home'; 


And in the view

PHP Code:

<?php if(!empty($canonical)) echo '<link rel="canonical" href="'.site_url($canonical).'">'; ?>

However, I only use it for pages like the home page where it can have several routes into it. perhaps this could be made dynamic using current_url() as described here: https://www.codeigniter.com/user_guide/h...urrent_url

However I am not sure if current_url returns the used url or the full url.

So not really an answer, just an idea about how it might be done.

Best wishes,

Paul.
