YOAST SEO - Canonical link is incorrect on paginated pages in secondary language when using language as a parameter

 
// define the wpseo_canonical callback 
function wpmldp_filter_wpseo_canonical_lang_parameter_position( $canonical ) { 
        // decode URL
        $canonical = urldecode($canonical);
	
	// get current language
	$my_current_lang = apply_filters( 'wpml_current_language', NULL );
	
	// define ?lang parameter
	$param = '?lang='.$my_current_lang;
	
	// check if current $canonical contains the parameter
	if(strpos($canonical, $param) !== false){
		
		// remove the parameter from URL
		$canonical = str_replace('/'.$param, "", $canonical);
		
		// add it again
		$canonical = $canonical.$param;
	}	
	
    return $canonical; 
}; 
         
// add the filter 
add_filter( 'wpseo_canonical', 'wpmldp_filter_wpseo_canonical_lang_parameter_position', 999 );

1. Hi,
   I have encountered this problem discovered when analysing the head tag

   N’est pas une URL absolue (https%3A%2F%2Fscience-sense.com%2F)

   Finally I corrected the problem by dis-activating your plugin part of the wpml bundle.

   I tried your code (activated) in the functions file and cleared the site and navigator cache but the problem persisted.

   Please tell me what to do next so that I can use this paid version of wpml SEO

   Regards

2. Hi,

   I’ve added this code and it seemed to work but now I get the following fatal error:

   Fatal error: Uncaught Error: call_user_func_array(): Argument #1 ($callback) must be a valid callback, function “wpmldp_filter_wpseo_canonical_lang_parameter_position” not found or invalid function name

   Is there another way to temporarily fix this issue?

   • Hello Jaap,
     I’ve updated this page as the workaround lost its format and there could have an issue. Could you please give it another try?
     If it still does not work, please open a chat in our support forum and share your findings.
     We will investigate it further.

4. How about if pagination is with query strings in the format of /?page=2

   then what should we do if we want yoast seo to generate correct urls in canonical and rel next prev seo tags?

   • Hey there,
     This issue was related to Yoast plugin and not WPML. It should have been solved with Yoast SEO 20.3 version. I recommend you to contact their support for further information or if you are still experiencing this issue.
     Regards
