getCountries

The getCountries hook allows to modify the system’s list of countries.

Note

Using the getCountries hook has been deprecated and will no longer work in Contao 5.0. Decorate the Contao\CoreBundle\Intl\Countries service instead.

Parameters

  1. array $translatedCountries

    The array containing the countries as filled by \Contao\System::getCountries() according to the system’s configuration. This parameter has to be passed by reference if you want your changes to become effective.

  2. array $allCountries

    The list of countries from the system config file countries.php.

Example

// src/EventListener/GetCountriesListener.php
namespace App\EventListener;

use Contao\CoreBundle\DependencyInjection\Attribute\AsHook;

#[AsHook('getCountries')]
class GetCountriesListener
{
    public function __invoke(array &$translatedCountries, array $allCountries): void
    {
        // Codes for the european countries
        $europeanCountryCodes = ['de', 'at', 'ch' /*, … */];
    
        // Remove all non-european countries
        $translatedCountries = array_intersect_key($translatedCountries, array_flip($europeanCountryCodes));
    }
}
