Filter entries by Field value using a variable How do I filter a list of entries by the value of a field using the value of a variable? 

e.g.

{% set location = block.locationVacancies %}
{% set entries = craft.entries.section('careers').search('locationVacancies:"{{location}}"')


doesn't work for me. But if I replace {{location}} with the value of the string location by hand then it works

{% set entries = craft.entries.section('careers').search('locationVacancies:"uk"')
Twig has an interpolation syntax (using #{} inside a double-quoted string) to accomplish this:

{% set location = block.locationVacancies %}
{% set entries = craft
    .entries
    .section('careers')
    .search("locationVacancies:#{location}")
    .all() %}




In addition, you can be more explicit about the values you’re searching for (and avoid any kind of sneaky search capabilities/side-effects exposed by using raw query input):

{% set location = block.locationVacancies %}
{% set entries = craft
    .entries
    .section('careers')
    .locationVacancies("*#{location}*")
    .all() %}


…or even using Twig object syntax…

{% set location = block.locationVacancies %}
{% set entries = craft.entries({
    section: 'careers',
    locationVacancies: "*#{location}*"
}).all() %}


(locationVacancies: location will also work, but disables partial matching)


  It should be noted: if you're looking to associate multiple explicit entries, you can also make the field within your (presumed) Matrix Block an Entries field, which establishes actual relationships in the database—accessing such a field (myBlock.myLocationEntriesField.all()) will return that list of Entries, exactly as set in the admin) If you just need a dynamic search param, what you have is a fine solution!
