How to add query parameters in twig using path()?

Question

I am following the code snippet provided here

{# Link to frontpage view. #} <a href="{{ path('view.frontpage.page_1') }}">{{ 'View all content'|t }}</a>

{# Link to user entity/profile page. #} <a href="{{ path('entity.user.canonical', {'user': user.id}) }}">{{ 'View user profile'|t }}</a>

{# Link to node page. #} <a href="{{ path('entity.node.canonical', {'node': node.id}) }}">{{ 'View node page'|t }}</a>

https://www.drupal.org/docs/8/theming/twig/functions-in-twig-templates#path

As the function says path($name, $parameters, $options), I want to add a link which has query parameters as shown in below

blue?destination=blue-search&cookie[blue_referrer]=3622&cookie[blue_type]=node

I tried implementing it as follows

<a href="{{ 
               path('blue_general.blue',
               {'node': node.id}, 
               {'query': [
                 'destination': path('view.blue_search.page_1'),
                 'cookie[blue_referrer]': node.id,
                 'cookie[blue_type]':'node'
                 ] 
                }
               ) 
               }}">Find a Distributor</a>

but it gives an error

The website encountered an unexpected error. Please try again later.Twig_Error_Syntax: An array element must be followed by a comma. Unexpected token "punctuation" of value ":" ("punctuation" expected with value ","). in Twig_TokenStream->expect() (line 124 of /templates/node/node--product.html.twig).

Answer 1

Twig uses hashes where PHP uses associative arrays. So to fix your code just convert the array syntax to a hash literal:

{{ 
  path('blue_general.blue',
    {'node': node.id}, 
    {'query': {
      'destination': path('view.blue_search.page_1'),
      'cookie[blue_referrer]': node.id,
      'cookie[blue_type]':'node'
    }}
  ) 
}}

Here is an example of passing views contextual filter value into path() twig function:

{% set ical_path = path('view.events.ical', {arg_0: 12}) %}
