Empty Coalesce Operator for Twig
================================

[](#empty-coalesce-operator-for-twig)

[![Packagist](https://camo.githubusercontent.com/ce8ebff4981efb1c45b6c2a5c393a129f866f3a0e11f6ada9c136577734dbb51/68747470733a2f2f696d672e736869656c64732e696f2f7061636b61676973742f762f67676c6e782f747769672d656d7074792d636f616c657363652e737667)](https://packagist.org/packages/gglnx/twig-empty-coalesce)

This library adds a new [operator expression](https://twig.symfony.com/doc/2.x/templates.html#expressions) to Twig with three question marks (`???`) to check if the left value is defined, not null and not empty. Works the same way as the [`empty` test](https://twig.symfony.com/doc/2.x/tests/empty.html) and the `|default` filter.

```
{% set _null = null %}
{% set _empty = '' %}

{# Null Coalesce: Output will be string(0) "" because _empty is defined and not exactly null #}
{{ dump(_undefined ?? _null ?? _empty ?? 'fallback') }}

{# Default Filter: Output will be string(8) "fallback" because _empty is defined, but an empty string #}
{{ dump(_undefined | default(_null | default(_empty | default('fallback')))) }}

{# Same as the default filter, but much more readable #}
{{ dump(_undefined ??? _null ??? _empty ??? 'fallback') }}
```
