How to add Canonical Tags on Opencart Products

[moon-boots]

Does anyone know how to add canonical tags to product pages in Opencart?

Is this possible to do in htaccess? If so, how specifically should it be written in?

Please do not post any links to other pages which reference generic canonical information as I've read them all and none help. I'm looking for an Opencart specific answer, or a way to do it in htaccess.

Apparently this didn't work. According to the Moz tool I have the same amount of duplicate title tags as before.

I suggerst you to adopt the following :

The best way to achieve this is to modify your Document class, set your canonical in your controller, then render it in the header controller.

Edit system/library/document.php

add:

private $canonical; to your class variables up top.

Then add the following methods:

<code>publicfunction setCanonical($url){ $this->canonical = $url;}publicfunction getCanonical(){return $this->canonical;}</code>

In your header controller add:

$this->data['canonical'] = $this->document->getCanonical();

Then you can set your canonical dynamically in the header controller:

<code>if(isset($this->request->get['_route_'])): $canonical_route = $this->request->get['_route_'];else: $canonical_route =''; endif; $this->document->setCanonical($this->data['base']. $canonical_route);</code>

Or you can set it manually in your controllers using the setCanonical method.

Hi there,

In continuation to my response earlier on another question.

Have u tried these extensions on Opencart? http://www.opencart.com/index.php?route=extension/extension&filter_search=canonical url
