How to use config value in symfony2 translation? - php

Question

Is it possible to use global variable from config.yml in translation file in symfony 2?
If yes, please can you give some example or useful link?

Answer 1

For injecting a (or all) twig globals into your translations you need to override the translation service. Check out this answer if you want a detailed explanation. Here is what I did:
Override the translator.class parameter (e.g. in your parameters.yml):
translator.class: Acme\YourBundle\Translation\Translator
Create the new Translator service:
use Symfony\Bundle\FrameworkBundle\Translation\Translator as BaseTranslator;
class Translator extends BaseTranslator
{
}
Finally override both trans and transChoice:
/**
* {#inheritdoc}
*/
public function trans($id, array $parameters = array(), $domain = null, $locale = null)
{
return parent::trans(
$id,
array_merge($this->container->get('twig')->getGlobals(), $parameters),
$domain,
$locale
);
}
/**
* {#inheritdoc}
*/
public function transChoice($id, $number, array $parameters = array(), $domain = null, $locale = null)
{
return parent::transChoice(
$id,
$number,
array_merge($this->container->get('twig')->getGlobals(), $parameters),
$domain,
$locale
);
}
In this example I am injecting all twig globals. You can only inject one like this:
array_merge(['%your_global%' => $this->container->get('twig')->getGlobals()['your_global']], $parameters)

Answer 2

You can follow those 2 simple steps:
Inject a Global variable in all the templates using the twig configuration:
# app/config/parameters.yml
parameters:
my_favorite_website: www.stackoverflow.com
And
# app/config/config.yml
twig:
globals:
my_favorite_website: "%my_favorite_website%"
Use Message Placeholders to have the ability to place your text in your translation:
# messages.en.yml
I.love.website: "I love %website%!!"
# messages.fr.yml
I.love.website: "J'adore %website%!!"
You now can use the following twig syntax in your templates to get your expected result:
{{ 'I.love.website'|trans({'%website%': my_favorite_website}) }}
