how to concatenate multiple variables and strings

Question

I am trying to form a url parameter (for Google Maps API) from entry field data. Basically, this is what I would like to do:

{% set street = entry.address %}

{% set  city = entry.city %}

{% set urlParam = street.", ".city.", UT"  %}

Is this possible with Twig and, if so, what is the proper syntax for concatenating multiple variables and strings?

Thanks!

Answer 1

Another option is to use the twig join filter:

{% set urlParam = [street, city, 'UT']|join(', ') %}

join concatenates the items in the sequence with the separator of your choice in between.

Answer 2

Figured it out! Proper syntax is:

{% set urlParam = street ~", " ~city ~", UT"  %}

Answer 3

Just wanted to add another example to this since this post help point me in the right direction.

In my example, I am getting back a list of events from a 3rd party. All that is returned to me is the slug. But, you can see that I wanted the url to be prepended with /event-results/.

<a href="{{ url('/evnet-results/'~event.slug) }}">{{ event.title }}</a>
