Root relative site URLs no longer work

[timkelty]

I think this was introduced here: c17487b#diff-8761a7cd35e729b6fadc9ebfa1200391

craft\helpers\UrlHelper::url will now always return a full url, even if your siteUrl is explicitly root relative (e.g. /)

I don’t think it was that commit, and don’t remember the exact issue off the top of my head, but the change was intentional.

Looking at the changelog, I'm guessing it was this:

Generated site URLs now always include full host info, even if the base site URL is root/protocol-relative.

So root/protocol relative values are ok in the siteUrl setting, but any generated URLs will have full path info. That seems a bit confusing to me.

My use-case for wanting a root-relative siteUrl is using Craft as a detached API, where having full URLs sometimes doesn't make sense. Obviously there are times where you do need a full URL though (URLs in email).

It almost seems like maybe there could be a third template rendering mode (CP, site, email/external) to manage things like this.

Right, that's the one. Committed in 4848022, which fixed #2919.

It’s pretty easy to turn an absolute URL into a root-relative URL using parse_url(), so maybe you could just use that when you need it?

$url = parse_url($url, PHP_URL_PATH);

so maybe you could just use that when you need it?

In my case that's not really a possibility (I don't think), as this is an API (CraftQL), not Twig – so I'd have to know any field/fieldtype that might use craft\helpers\UrlHelper::url and tap into it somehow.

If craft\helpers\UrlHelper::url had an event hook, that would be one way.

At this point, I'm all set: I'm just making the dev consuming my API parse the URI out. :)
