WordPress Rewrite Rule to exclude specific slug

问题

I have a rewrite rule in my functions.php which is working just fine.

function custom_offers_rewrite() {
  add_rewrite_rule('^offers/([a-z-_]+)/?', 'index.php?page_id=1948&offer_restaurant=$matches[1]', 'top');
}

This looks for anything like /offers/my-custom-path and then loads in a specific page template / ID (page_id=1948). This template displays some custom things and we're all good.

Whilst that's fine, I have a literal page on the URL path, /offers/all and I would like to exclude this from the rewrite rule.

Is this possible at all?

So, in other words, if we hit /offers/all, just ignore the rule and carry on as normal. If anything else, do the rule as it currently works.

I suppose it needs some adjustment to the Regex, but I'm barely any good at pattern matching.

Help and advice appreciated. Many thanks!

Okay, I figured it out eventually.

Working code that will ignore /offers/all but work with everything else:

function custom_offers_rewrite() {
  add_rewrite_rule('^offers/(?!all)([a-z-_]+)/?', 'index.php?page_id=1948&offer_restaurant=$matches[1]', 'top');
}

The key part, being the addition of (?!all) into the Regex.

Hope this manages to help someone else.

Important: Remember to save the permalinks in WordPress in order to flush the rewrite cache!
