wpml_object_id parameters in fix_language_mismatch

Hi @mpdechit,

I need to conduct additional testing to ensure that this change does not break anything. In general, the last argument in the filter should be the language code taken from the URL, and stating a language code of the detected element ($element_language_code) there may disrupt some custom implementations.

A good alternative idea could be to overwrite the whole function where this line of code is used:

function pmp_fix_language_mismatch($item_id, $uri_parts, $is_term = false) {
	global $wp, $polylang, $language_code, $permalink_manager_options;

	$mode = (!empty($permalink_manager_options['general']['fix_language_mismatch'])) ? $permalink_manager_options['general']['fix_language_mismatch'] : 0;

	if($is_term) {
		$element = get_term($item_id);
		if(!empty($element) && !is_wp_error($element)) {
			$element_id = $element->term_taxonomy_id;
			$element_type = $element->taxonomy;
		} else {
			return false;
		}
	} else {
		$element = get_post($item_id);

		if(!empty($element->post_type)) {
			$element_id = $item_id;
			$element_type = $element->post_type;
		}
	}

	// Stop if no term or post is detected
	if(empty($element)) { return false; }

	// Get the language code of the found post/term
	$element_language_code = Permalink_Manager_Language_Plugins::get_language_code($element);

	// Get the detected language code
	if(defined('ICL_LANGUAGE_CODE')) {
		$detected_language_code = ICL_LANGUAGE_CODE;
	} else if(!empty($uri_parts['lang'])) {
		$detected_language_code = $uri_parts['lang'];
	} else {
		return $item_id;
	}

	if($detected_language_code !== $element_language_code) {
		$item_id = apply_filters('wpml_object_id', $element_id, $element_type, false, $element_language_code);
	}

	return $item_id;
}
add_filter('permalink_manager_detected_post_id', 'pmp_fix_language_mismatch', 10, 3);
