I have this array called theme in a Twig template:
array:4 [▼
"foo" => "bar"
"headerimage" => array:6 [▶]
"templatefields" => array:1 [▶]
"assets" => array:3 [▼
"css" => array:1 [▶]
"js" => array:1 [▶]
"libs" => array:2 [▼
0 => "jquery"
1 => "bootstrap"
]
]
]
I wanna add more elements in theme.assets.libs . I try with:
{% set theme.assets.libs = theme.assets.libs|merge(['otherlibrary', 'anotherlibrary']) %}
But I have the next error.
Unexpected token "punctuation" of value "." ("end of statement block" expected) in "index.twig" at line 7.
Twig doesn't allow doing this directly. You can instead, however, do this by continuing the pattern of array merges you're already doing:
{% set theme = theme|merge({assets: theme.assets|merge({ libs: theme.assets.libs|merge(['otherlibrary', 'anotherlibrary']) }) }) %}
