Hello,

i try to add values to woocommerce product permalink.

my code :

//add rewrite rules 
function product_add_rewrite_rules() {
	global $wp_rewrite;
    
	$wp_rewrite->add_rewrite_tag('%product%', '([^/]+)', 'product=');
	$wp_rewrite->add_rewrite_tag('%subtitle%', '([^/]+)', 'subtitle=');
	$wp_rewrite->add_rewrite_tag('%artiste%', '([^/]+)', 'artiste=');
	$wp_rewrite->add_rewrite_tag('%numero_de_page%', '([^/]+)', 'numero_de_page=');
	$wp_rewrite->add_permastruct('product', '/catalogue/%artiste%-%product%-%subtitle%-page-%numero_de_page%/', false);
    
    $wp_rewrite->flush_rules();
}
add_action('init', 'product_add_rewrite_rules', 10, 0);

// replace the rwrite tag by the content
function product_permalinks($permalink, $post, $leavename) {
	$post_id = $post->ID;

	if ($post->post_type == 'product') {
		$subtitle = sanitize_title(get_field('subtitle', $post_id));
		$artiste = get_field('artiste', $post_id);
        $artistesurname = sanitize_title($artiste->name);
		$pagenumber = sanitize_title(get_field('numero_de_page', $post_id));
		if ($artiste) { 
			$permalink = str_replace('%artiste%', $artistesurname, $permalink);
		} else {
			$permalink = str_replace('%artiste%', 0, $permalink);
		}
        if ($subtitle) { 
			$permalink = str_replace('%subtitle%', $subtitle, $permalink);
		} else {
			$permalink = str_replace('%subtitle%', 0, $permalink);
		}
        if ($pagenumber) { 
			$permalink = str_replace('%numero_de_page%', $pagenumber, $permalink);
		} else {
			$permalink = str_replace('%numero_de_page%', 0, $permalink);
		}
	}

	return $permalink;
}
add_filter('post_type_link', 'product_permalinks', 10, 3);

In the backend it’s showing the change :

But in frontend i get a 404. I tried on an other custom post and i get the same.
Anyone had already the same problem ?

Thanks in advance,

Simon
