Regex to remove trailing slash not working

Question

I am trying to remove the http:// and trailing slash from a string, so my replace filter looks like this:

website|replace({ 'http://': '', '/\\/$/': '' })

The http:// part works, the trailing slash one doesn't. Why not?

Answer 1

I think you are getting the twig replace filter (which does not have the regex capability) instead of the Craft replace filter (which does).

So this is a bug in Craft, in that their filter is masked by the twig one.

You could use the trim filter to remove trailing /s:

website|replace({'http://':''})|trim('/')

Or you could use one of Victor's Twig PCRE Filters.

Craft's replace filter only supports doing multiple strings replacements at once. If you want to do a regex replacement, it will have to be it's own separate call.

In your case, you'd have to do something like this:

{% set url =  "http://www.google.com/"|replace('http://', '') %}
{{ url|replace('/\\/$/', '') }}
