map¶
New in version 1.41: The map filter was added in Twig 1.41 and 2.10.
The map filter applies an arrow function to the elements of a sequence or a
mapping. The arrow function receives the value of the sequence or mapping:
1 2 3 4 5 6 7 | {% set people = [
{first: "Bob", last: "Smith"},
{first: "Alice", last: "Dupond"},
] %}
{{ people|map(p => "#{p.first} #{p.last}")|join(', ') }}
{# outputs Bob Smith, Alice Dupond #}
|
The arrow function also receives the key as a second argument:
1 2 3 4 5 6 7 | {% set people = {
"Bob": "Smith",
"Alice": "Dupond",
} %}
{{ people|map((last, first) => "#{first} #{last}")|join(', ') }}
{# outputs Bob Smith, Alice Dupond #}
|
Note that the arrow function has access to the current context.
Arguments¶
arrow: The arrow function
