How to add self canonical url to facet pages?

Hello,

Thank you for contacting Rank Math today.

To noindex paginated pages, please enable the option in Rank math > Titles & Meta > Misc

Rank Math automatically adds a self canonical tag to your pages. To change this, you can customize the following filter to use the current URL as the canonical:

/**
 * Allow changing of the canonical URL.
 *
 * @param string $canonical The canonical URL.
 */
add_filter( 'rank_math/frontend/canonical', function( $canonical ) {
	return $canonical;
});

Hope that helps you. Thank you.

Hello,

Since I am not sure of the structure your URL are using (you said as an example this one: wyx .com/wooden-table/?color-red&&Type-Leather%%page2 but usually URLs don’t have the & added twice (nor the %) so maybe it was a mistake), I can give you a base code and you can customize it from there:

/**
 * Allow changing of the canonical URL.
 *
 * @param string $canonical The canonical URL.
 */
add_filter( 'rank_math/frontend/canonical', function( $canonical ) {
         // We use this since $canonical doesn't have the query string
         $queryString = $_SERVER['QUERY_STRING'];
         $url = $_SERVER['HTTP_HOST'] . $_SERVER['SCRIPT_NAME'] . "?" . $queryString;

        // Now you should check if $queryString contains some parameters and if it does you would need to extract from there the pagination
        // For example, you could save it in a var like: $pagination
        // And return the new canonical like this: return $canonical . $pagination
	return $canonical;
});

Looking forward to help you.

Hello,

I am trying to check it but after applying filters the URL I am getting is the one I shared in the Sensitive Data section and not one with && nor ?

Is it a correct URL you want to canonicalize?

Looking forward to help you.

Hello,

Could we log in your site to try the snippet there so it is easy to debug? To do that, please edit the first post on this ticket and include your WP logins in the designated Sensitive Data section.

It is completely secure and only our support staff has access to that section. If you want, you can use the below plugin to generate a temporary login URL to your website and share that with us instead:

You can use the above plugin in conjunction with the WP Security Audit Log to monitor what changes our staff might make on your website (if any):

We really look forward to helping you.

Hello,

I am sorry, I didn’t see the thread updated with your credentials. I am now trying to add the modifications but each time I try to save the modifications I am getting issues saving the functions.php file. Could you share some FTP credentials so I can modify the file from there?

Looking forward to help you.
