Symfony parameters variable in variable

Question

I work on a symfony project and I want to do something like this in my app/config/parameters.yml

dev.google.api.key: foo
google: %%kernel.environment%.google%

It not works.

I explain : I want to have the variable google to have values depending my environment (env or prod).

So I defined two variable :

dev.google.api.key: foo
prod.google.api.key: bar

I want to have my variable google to be filled with content depending on the environment. The environment is in the variable

%kernel.environment%

So if I do :

google: %kernel.environment%.google

Google is equal to "dev.google" but I want to this string to be evaluated like this %dev.google%. But %%kernel.environment%.google% not works.

An idea ? Thanks

I don't think it is possible. But I think you complexify your need. Do you really need to declare this parameters ? you have config_dev.yml and config_prod.yml file — Arno, Sep 27 '17 at 15:44
Yes but a cannot accès content from config.yml on my twig files. I want to add this vars to my twig : globals. But to keep this variables in parameters to avoid adding variables in multiple files. But give up, I put my vars in config_env. Thanks — ReaperSoon, Sep 27 '17 at 17:33

You can try something like this:

in your config_dev.yml:

parameters:
    google.api.key: foo

in your config_prod.yml:

parameters:
    google.api.key: bar

in your config.yml:

google: %google.api.key%

Or

Create paramater_dev.yml with

parameters:
    google.api.key: foo

Create paramater_prod.yml with

parameters:
    google.api.key: bar

in your config_dev.yml:

imports:
    - { resource: paramater_dev.yml }
    - { resource: config.yml }

in your config_prod.yml:

imports:
    - { resource: paramater_prod.yml }
    - { resource: config.yml }

in your config.yml:

google: %google.api.key%
