I’ve inherited a site using Code Snippets plugin which has a snippet to rewrite URLs.
Unfortunately, I am not a developer so I am unsure what these do.
The problem we have is that in the Yoast SEO sitemap, the blog post URLs do not have a trailing slash. If you click on one of these links it redirects you to the URL with the trailing slash.
Ahrefs.com reports it is not a good idea to have 301 redirects in the sitemap.
If we disable the Code Snippets plugin, the problem goes away. I am pretty sure the snippet in question is:
function mandoe_blog_rewrite_rules( $wp_rewrite ) {
$new_rules = array(
'(([^/]+/)*blog)/page/?([0-9]{1,})/?$' => 'index.php?pagename=$matches[1]&paged=$matches[3]',
'blog/([^/]+)/?$' => 'index.php?post_type=post&name=$matches[1]',
'blog/[^/]+/attachment/([^/]+)/?$' => 'index.php?post_type=post&attachment=$matches[1]',
'blog/[^/]+/attachment/([^/]+)/trackback/?$' => 'index.php?post_type=post&attachment=$matches[1]&tb=1',
'blog/[^/]+/attachment/([^/]+)/feed/(feed|rdf|rss|rss2|atom)/?$' => 'index.php?post_type=post&attachment=$matches[1]&feed=$matches[2]',
'blog/[^/]+/attachment/([^/]+)/(feed|rdf|rss|rss2|atom)/?$' => 'index.php?post_type=post&attachment=$matches[1]&feed=$matches[2]',
'blog/[^/]+/attachment/([^/]+)/comment-page-([0-9]{1,})/?$' => 'index.php?post_type=post&attachment=$matches[1]&cpage=$matches[2]',
'blog/[^/]+/attachment/([^/]+)/embed/?$' => 'index.php?post_type=post&attachment=$matches[1]&embed=true',
'blog/[^/]+/embed/([^/]+)/?$' => 'index.php?post_type=post&attachment=$matches[1]&embed=true',
'blog/([^/]+)/embed/?$' => 'index.php?post_type=post&name=$matches[1]&embed=true',
'blog/[^/]+/([^/]+)/embed/?$' => 'index.php?post_type=post&attachment=$matches[1]&embed=true',
'blog/([^/]+)/trackback/?$' => 'index.php?post_type=post&name=$matches[1]&tb=1',
'blog/([^/]+)/feed/(feed|rdf|rss|rss2|atom)/?$' => 'index.php?post_type=post&name=$matches[1]&feed=$matches[2]',
'blog/([^/]+)/(feed|rdf|rss|rss2|atom)/?$' => 'index.php?post_type=post&name=$matches[1]&feed=$matches[2]',
'blog/page/([0-9]{1,})/?$' => 'index.php?post_type=post&paged=$matches[1]',
'blog/[^/]+/page/?([0-9]{1,})/?$' => 'index.php?post_type=post&name=$matches[1]&paged=$matches[2]',
'blog/([^/]+)/page/?([0-9]{1,})/?$' => 'index.php?post_type=post&name=$matches[1]&paged=$matches[2]',
'blog/([^/]+)/comment-page-([0-9]{1,})/?$' => 'index.php?post_type=post&name=$matches[1]&cpage=$matches[2]',
'blog/([^/]+)(/[0-9]+)?/?$' => 'index.php?post_type=post&name=$matches[1]&page=$matches[2]',
// 'blog/[^/]+/([^/]+)/?$' => 'index.php?post_type=post&attachment=$matches[1]',
'blog/[^/]+/([^/]+)/trackback/?$' => 'index.php?post_type=post&attachment=$matches[1]&tb=1',
'blog/[^/]+/([^/]+)/feed/(feed|rdf|rss|rss2|atom)/?$' => 'index.php?post_type=post&attachment=$matches[1]&feed=$matches[2]',
'blog/[^/]+/([^/]+)/(feed|rdf|rss|rss2|atom)/?$' => 'index.php?post_type=post&attachment=$matches[1]&feed=$matches[2]',
'blog/[^/]+/([^/]+)/comment-page-([0-9]{1,})/?$' => 'index.php?post_type=post&attachment=$matches[1]&cpage=$matches[2]',
);
$wp_rewrite->rules = array_merge($new_rules, $wp_rewrite->rules);
}
add_action( 'generate_rewrite_rules', 'mandoe_blog_rewrite_rules' );
function mandoe_update_post_link( $post_link, $id = 0 ) {
$post = get_post( $id );
if( is_object( $post ) && $post->post_type == 'post' ) {
return home_url( '/blog/' . $post->post_name );
}
return $post_link;
}
add_filter( 'post_link', 'mandoe_update_post_link', 1, 3 );
Can you please help identify which part of the code needs to be adjusted to add a trailing slash to blog posts?
Help appreciated.
