Use ternary statements in Twig

ternary-example.html.twig

{# Checks if a URL exists and passes it to the component. Otherwise, sets it to false. Works with primitive data types. #}
{% set link = url ? { url: url } : false %}

{# Checks if the media object is not empty and passes it to the component. Otherwise, sets it to false. Suitable for complex data types like objects. #}
{% set media = media is not empty ? { media: media } : false %}

Issue:

You want to conditionally pass values to components in Twig based on variable existence or content.

Solution:

Uses Twig’s ternary operator to check variable conditions and pass either an object with the variable or false.

If you're working with more complex objects, make sure to handle the empty test according to the Twig documentation on empty, as its behavior may vary depending on the object's implementation.
