We need to show a certain page on Wordpress using a different domain, so via .htaccess we do this:

RewriteCond %{HTTP_HOST} ^(www\.)?mydomain.org.uk$ [NC]
RewriteRule ^(.*)$ index.php?page_id=37440 [NC,QSA]

The page in question is password protected, but the standard password protection form will include the main site domain, and when clicking submit to login it in goes to a blank page.

So we customised the password protection form to submit to the new domain, e.g.

function my_password_form($form)
{
    if(get_the_ID() == '37440' )
    {   
        $form = '<form action="https://www.mydomain.org.uk/wp-login.php?action=postpass" class="post-password-form" method="post">
<p>This content is password protected. To view it please enter your password below:</p>
<p><label for="pwbox-37440">Password: <input name="post_password" id="pwbox-37440" type="password" size="20"></label> <input type="submit" name="Submit" value="Enter"></p>
</form>
        ';
    }
    return $form;
}
add_filter( 'the_password_form', 'my_password_form' );

Now the action is changed to the new domain, but when clicking Submit it goes to the following URL but it says its a 404:

https://www.mydomain.org.uk/wp-login.php?action=postpass

I also tried dynamically setting the site URL in wp-config.php depending on the domain uses (which I have successfully done in the past on another site which needed a second domain) but this also goes to a 404.

if($_SERVER['HTTP_HOST'] == 'www.mydomain.org.uk')
{
    define('WP_HOME', 'https://www.mydomain.org.uk/');
    define('WP_SITEURL', 'https://www.mydomain.org.uk/');
}

Does anyone know why, and how can we allow a login to the password protection page from this second domain?

Thanks

  • This sounds like you want to 'mask' the url by showing different content which is doable within .htaccess. Try reading this: https://stackoverflow.com/questions/14928498/htaccess-url-masking-instead-of-redirecting. – sativay Nov 14 '20 at 07:30
  • Thanks but I have masked it ok that’s working. It’s logging into the password protected form that’s not. – Laurence Cope Nov 14 '20 at 08:40
  • What about multi-site WordPress? – sativay Nov 14 '20 at 11:09
