Hey @gelanivishal and @brandon_pagan
I think I know a better way to do it correct and conveniently.
1. Create your module.
2. Create your Helper, e.g. [Namespace]/[Module]/Helper/Canonical.php
<?php
declare(strict_types=1);
namespace [Namespace]\[Module]\Helper;
use Magento\Cms\Model\Page;
use Magento\Framework\App\Helper\AbstractHelper;
use Magento\Framework\App\Helper\Context;
/**
* Class Canonical
* @package [Namespace]\[Module]\Helper
*/
class Canonical extends AbstractHelper
{
/**
* @var Page
*/
protected $cmsPage;
/**
* Canonical constructor.
* @param Context $context
* @param Page $cmsPage
*/
public function __construct(
Context $context,
Page $cmsPage
) {
$this->cmsPage = $cmsPage;
parent::__construct($context);
}
/**
* This method is used in XML layout.
* @return string
*/
public function getCanonicalForAllCmsPages(): string
{
if ($this->cmsPage->getId()) {
return $this->createLink(
$this->scopeConfig->getValue('web/secure/base_url') . $this->cmsPage->getIdentifier()
);
}
return '';
}
/**
* @param $url
* @return string
*/
protected function createLink($url): string
{
return '<link rel="canonical" href="' . $url . '" />';
}
}3. Create layout: [Namespace]/[Module]/view/frontend/layout/default.xml
<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
<body>
<referenceBlock name="head.additional">
<container name="canonical.url.cms.page.container">
<block class="Magento\Framework\View\Element\Text" name="canonical.url.cms.page">
<arguments>
<argument name="label" xsi:type="string">Adding canonical link with base URL</argument>
<argument name="text" xsi:type="helper" helper="[Namespace]\[Module]\Helper\Canonical::getCanonicalForAllCmsPages"/>
</arguments>
</block>
</container>
</referenceBlock>
</body>
</page>4. Run bin/magento setup:upgrade
5. See if it works the way you wanted.
Now, on every CMS Page the canonical link will be added automatically.
Have a nice day.
