Is the first example wrong? There's no $canonical_url variable in the wpseo plugin.
@campaignupgrade The example is correct. The $canonical_url is a local variable for the custom function.
Bonus: Last tested date has been updated as I verified it worked today. Plus I added another snippet to remove the trailing slash for those that might need to do the opposite. Renamed the snippets to better align with what the code does.
Ah I see. If it's not pulling an already-defined varaible like $canonical it's just a local variable and it replaces whatever the output of generate_canonical().
I'm looking for a clean way to replace the base_url of all my non-production sites with my production base_url. Unfortunately it doesn't look like I can override the individual subfunctions involved, so would a pregex_replace( $canonical ) approach be the only option?
I'm short on time and haven't thoroughly tested this, but it's working so far:
/**
* Set canonical URLs on non-production sites to the production URL
* Stops bots from indexing
* @link https://gist.github.com/amboutwe/2aa7dcc9a38986e11fac68c7306cc091
*/
add_filter( 'wpseo_canonical', function( $canonical ) {
if( 'https://example.com' == get_option( 'home' ) ) {
return $canonical;
}
$canonical = preg_replace('#//[^/]*/#U', '//example.com/', trailingslashit( $canonical ) );
return $canonical;
});
I have a page that is generated only in php !
So Is there a way to add a custom canonical or title/description tags for this specific page ?
Any help would be much appreciated ?

Hi, does anyone knows how can I fix this? Somes slashes BEFORE my canonicals started to appear on all pages like the image below:

yoast_seo_canonical_change_woocom_shop - dont work
Canonical links and rel="prev" and rel="next" are removed on pages with "noindex" meta tag. Is there any way to force add them?
When I go to an URL like myblog.com/blog/mypost/?what-is-my-canonical that has a query string on it, the canonical will be set to myblog.com/blog/mypost/?what-is-my-canonical.
In my eyes, the best canonical here would be myblog.com/blog/mypost/.
Is there a way to get rid of query strings for canonicals for blog posts?
Can we remove canonicals for only one post type (any specific)?
I am creating custom canonicals but Yoast gives me another canonical also, I want to replace canonical for that post-type generated by Yoast, not for other post types & pages.
@Suny-ticket Yes, the remove_post.php is for a single post, but that can be adjusted to be wider (all content matching specific criteria) depending on your needs. These are just a few examples so you or your developer have a starting point for the customization.
