Custom Twig extras for Twig 3.22+ and PHP 8.4+:

• switch tag
• ?. nullsafe operator

Installation

composer require felds/twig-extra

Usage

Register the desired extensions with Twig:

$twig->addExtension(new \Felds\TwigExtra\SwitchExtension());
$twig->addExtension(new \Felds\TwigExtra\NullsafeExtension());

In Symfony, you can let autoconfigure pick it up by registering the services:

# services.yaml
Felds\TwigExtra\SwitchExtension: ~
Felds\TwigExtra\NullsafeExtension: ~

Switch tag ({% switch %})

Match a value against multiple comparisons, picking the first case that evaluates truthy:

{% switch value %}
{% case 1 %} exactly 1
{% case == 2 %} exactly 2
{% case > 1 %} More than 1
{% default %} Other
{% endswitch %}

• Supports all Twig comparison operators (==, !=, >, <, >=, <=, is same as, in, not in, matches, starts with, ends with, etc.).
• Cases are evaluated top-down; the first hit wins, otherwise default runs when present.
• The switch value is stored internally and the original context is restored after the block.

Nullsafe operator (?.)

Access attributes and call methods without throwing when the left side is null or missing:

{{ user?.name }}
{{ post?.author?.getName() }}
{{ date?.format('Y-m-d') ?? 'no date' }}

• If the base value is null or undefined, the chain short-circuits to null.
• Works with arrays, objects, property fetches, and method calls.
• Respects strict variables (nullsafe short-circuits instead of raising).
