How to 301 redirect only posts in WordPress

Redirecting an old WordPress website to a new one is simple as there are many plugins and solutions provided online. However, what I found to be challenging is redirecting only single WordPress posts to another site with or without a plugin.

Redirecting only Posts

To redirect only WordPress posts to a new website then add the code below to your functions.php file in your WordPress child theme.

// Redirect existing posts only

add_action(‘template_redirect’, ‘blogies_post_redirect_only’);

function blogies_post_redirect_only() {

    global $post;

       if (is_single($post->ID)) {

        $new_url = “https://example.com/{$post->post_name}/”; 

        wp_redirect($new_url, 301);

        exit;

    }

}

is_single is used to check whether a query is a single post.

 $new_url variable is used to redirect to the new URL.

NOTE 1

Replace example.com with your domain name. If you are using a subdomain or subfolder for example “example.com/blog/“, then your new URL should be https://example.com/blog/{$post->post_name}/

NOTE 2

This redirect method only works for published posts. Draft, trash, or deleted posts will not redirect. You will get a 404 error.

If you want to redirect the entire website then add the code below to your htaccess file

# redirect the entire website

RewriteEngine on

RewriteCond %{HTTP_HOST} ^oldmain.com [NC,OR]

RewriteCond %{HTTP_HOST} ^www.oldmain.com [NC]

RewriteRule ^(.*)$ https://newdomain.com/$1 [L,R=301,NC]

Replace oldmain.com and newdomain.com with your old and new domain respectively.
