Twig replace keyword dynamically

I wonder why this do not work

{% set what = 'hate' %}
{% set byValue = 'like' %}
{{ 'I hate twig'|replace( { what : byValue } ) }}

It should display I like twig isn't it?

The syntax to create associative arrays using Twig is:

{key1: value1, key2: value2, 'key3': value3, (key4): value4}...

Take care here:

  • key1 and key2 are HASH KEYS

  • 'key3' is a string

  • (key4) is an EXPRESSION (it evaluates your key4 variable)

  • value1 ... value4 are variables

HASH KEYS are basically literally considered as strings.

So, your array:

{ what : byValue }

Will create an array with a what key, instead of the content of your what variable. If you want to use an expression instead of a hash key, you just need to wrap your hash key (or even a number) with parenthesis.

{ (what) : byValue }

Just wrap the key with parentheses and Twig will treat it as a variable:

{{ 'I hate twig'|replace({ (what): byValue }) }}

Should

{{ 'I hate twig'|replace( { what : byValue } )) }}

be

{{ 'I hate twig'|replace( { what : byValue } ) }}
