    Hey,

    I have seen many implementation of this filter “the_seo_framework_rel_canonical_output”

    I need the post ID of the page in order to change the canonical link which I am unable to get.
    I could try “url_to_postid()” function but the problem is that I have changed the permalink of my website using a plugin which makes the link of my product pages link.

    example.com/category/product-slug

    So I am unable to get ID from there. A little bit of digging I found,

    

		/**
		 * @since 2.6.5
		 * @param string $url The canonical URL. Must be escaped.
		 * @param int    $id  The current page or term ID.
		 */
		$url = (string) \apply_filters_ref_array(
			'the_seo_framework_rel_canonical_output',
			[
				$_url,
				$this->get_the_real_ID(),
			]
		);

    I can see the URL being pased to the filter, but when I try to get it like this.

    

add_filter( 'the_seo_framework_rel_canonical_output', function( $url , $id ) {

	var_dump($url, $id);

	return $url;
} );

    I get the following error 

    
Too few arguments to function App\{closure}(), 1 passed in C:\laragon\www\cfi\wp-includes\class-wp-hook.php on line 289 and exactly 2 expected

    How can I get the ID of product here ?

    Thanks.

    Hello!

    You can set a custom canonical URL for every page under the Visibility tab of the Page SEO Settings (you can also access this via quick-edit). You should be able to use that if a page has an ID. Nevertheless, if you have special requirements, then filters do come in handy.

    WordPress’s custom PHP filters have four parameters: $tag, $function_to_add, $priority, and $accepted_args.
    You need to add the $accepted_args when you need to add more than one parameter.

    See: https://tsf.fyi/docs/filters

    add_filter( 'the_seo_framework_rel_canonical_output', function( $url , $id ) {

	var_dump($url, $id);

	return $url;
}, 10, 2 ); // Added '10, 2'

    I hope this helps! Cheers 🙂
