Symfony2：如何用全局Twig变量替换某个字符串？

Question

I have the following in config.yml

twig:
    globals:
        locale_list_sg: Singapore
        locale_list_cn: China

In my twig template, I will like to get the values "Singpaore" and "China" based on a argument. Therefore, I concatenate them like this and display:

{{'locale_list_' ~ countryId}}

However, the above will display locale_list_sg instead of going into config.yml and extract the values.

Answer 1

Use a simpler approach:

config.yml

twig:
    globals:
        locale_list: 
            sg: Singapore
            cn: China

template:

{{ locale_list[country_id] }}
