App

Check out the App Skeleton if you are using the skeleton.

You may also check out the App to learn more about the app in general.

Country Boot

The country boot does the following:

installs country files
implements country interfaces

use Tobento\App\AppFactory;

// Create the app
$app = (new AppFactory())->createApp();

// Add directories:
$app->dirs()
    ->dir(realpath(__DIR__.'/../'), 'root')
    ->dir(realpath(__DIR__.'/../app/'), 'app')
    ->dir($app->dir('app').'config', 'config', group: 'config')
    ->dir($app->dir('root').'public', 'public')
    ->dir($app->dir('root').'vendor', 'vendor');
    
// Adding boots
$app->boot(\Tobento\App\Country\Boot\Country::class);

// Run the app
$app->run();

Available Country Interfaces

The following interfaces are available after booting:

use Tobento\App\AppFactory;
use Tobento\Service\Country\CountryFactoryInterface;
use Tobento\Service\Country\CountriesFactoryInterface;
use Tobento\Service\Country\CountryRepositoryInterface;

// Create the app
$app = (new AppFactory())->createApp();

// Add directories:
$app->dirs()
    ->dir(realpath(__DIR__.'/../'), 'root')
    ->dir(realpath(__DIR__.'/../app/'), 'app')
    ->dir($app->dir('app').'config', 'config', group: 'config')
    ->dir($app->dir('root').'public', 'public')
    ->dir($app->dir('root').'vendor', 'vendor');
    
// Adding boots
$app->boot(\Tobento\App\Country\Boot\Country::class);
$app->booting();

$countryFactory = $app->get(CountryFactoryInterface::class);
$countriesFactory = $app->get(CountriesFactoryInterface::class);
$countryRepository = $app->get(CountryRepositoryInterface::class);

// Run the app
$app->run();

Check out the Country Service to learn more about the interfaces.

Retrieve Countries

You can retrieve countries by using the CountryRepositoryInterface::class:

use Tobento\App\AppFactory;
use Tobento\Service\Country\CountryRepositoryInterface;

// Create the app
$app = (new AppFactory())->createApp();

// Add directories:
$app->dirs()
    ->dir(realpath(__DIR__.'/../'), 'root')
    ->dir(realpath(__DIR__.'/../app/'), 'app')
    ->dir($app->dir('app').'config', 'config', group: 'config')
    ->dir($app->dir('root').'public', 'public')
    ->dir($app->dir('root').'vendor', 'vendor');
    
// Adding boots
$app->boot(\Tobento\App\Country\Boot\Country::class);
$app->booting();

$countryRepository = $app->get(CountryRepositoryInterface::class);

// Run the app
$app->run();

Check out the Country Repository Interface to learn more about it.

Add Or Customize Countries

Currently, countries are available in the locales en, de, fr and it.

You might add or customize/override new countries by the following way:

use Tobento\App\AppFactory;
use Tobento\Service\Country\CountryRepositoryInterface;

// Create the app
$app = (new AppFactory())->createApp();

// Add directories:
$app->dirs()
    ->dir(realpath(__DIR__.'/../'), 'root')
    ->dir(realpath(__DIR__.'/../app/'), 'app')
    ->dir($app->dir('app').'config', 'config', group: 'config')
    ->dir($app->dir('root').'public', 'public')
    ->dir($app->dir('root').'vendor', 'vendor');
    
// Add country directory with higher priority:
$this->app->dirs()->dir(
    dir: $this->app->dir('app').'countries-custom/',
    
    // do not use 'countries' as name for migration purposes
    name: 'countries.custom',
    
    group: 'countries',
    
    // add higher priority as default countries dir:
    priority: 300,
);

// Adding boots
$app->boot(\Tobento\App\Country\Boot\Country::class);

// Run the app
$app->run();

Then just add the countries files you wish to override in the defined directory. If the file does not exist, the file from the default country directory is used.

Using Countries In Forms

The following examples require the App View bundle with the following boots:

// ...

$app->boot(\Tobento\App\View\Boot\View::class);
$app->boot(\Tobento\App\View\Boot\Form::class);

// ...

Example using countries column

use Tobento\Service\Country\CountryRepositoryInterface;
use Tobento\Service\Country\CountryInterface;
use Tobento\Service\View\ViewInterface;

$countryRepository = $app->get(CountryRepositoryInterface::class);
$countries = $countryRepository->findCountries(locale: 'de');

// You may filter countries:
$countries = $countries->only(['CH', 'US']);

$view = $app->get(ViewInterface::class);

$content = $view->render(view: 'countries/select', data: [
    'countries' => $countries->column(column: 'name', index: 'code'),
]);

The views/countries/select.php view:

<?= $view->form()->select(
    name: 'countries[]',
    items: $countries,
    emptyOption: ['none', '---'],
) ?>
/*
<select name="countries[]" id="countries">
    <option value="none">---</option>
    <option value="CH">Schweiz</option>
    <option value="US">Vereinigte Staaten</option>
</select>
*/

You may check out the Select Form Element to learn more about it.

Example grouping countries by continents

use Tobento\Service\Country\CountryRepositoryInterface;
use Tobento\Service\Country\CountryInterface;
use Tobento\Service\View\ViewInterface;

$countryRepository = $app->get(CountryRepositoryInterface::class);
$countries = $countryRepository->findCountries(locale: 'de');

// Grouped column:
$groupedCountries = $countries->groupedColumn(group: 'continent', column: 'name', index: 'code');
ksort($groupedCountries);

$view = $app->get(ViewInterface::class);

$content = $view->render(view: 'countries/select', data: [
    'countries' => $groupedCountries,
]);

The views/countries/select.php view:

<?= $view->form()->select(
    name: 'countries[]',
    items: $countries,
    selectAttributes: [],
    optionAttributes: [],
    optgroupAttributes: [],
) ?>
/*
<select name="countries[]" id="countries">
    <optgroup label="Afrika">
        <option value="DZ">Algerien</option>
        ...
    </optgroup>
    <optgroup label="Antarktika">
        <option value="AQ">Antarktis</option>
        ...
    </optgroup>
    ...
</select>
*/

Example grouping countries by custom group

use Tobento\Service\Country\CountryRepositoryInterface;
use Tobento\Service\Country\CountryInterface;
use Tobento\Service\View\ViewInterface;

$countryRepository = $app->get(CountryRepositoryInterface::class);
$countries = $countryRepository->findCountries(locale: 'de');

// Handle grouping:
$countries = $countries->map(function(CountryInterface $c) {
    if (in_array($c->code(), ['CH', 'FR'])) {
        return $c->withGroup('Near By')->withPriority(100);
    }
    return $c->withGroup('All Others');
});

// You may sort it by priority:
$countries = $countries->sort(
    fn(CountryInterface $a, CountryInterface $b): int => $b->priority() <=> $a->priority()
);

// Grouped column:
$groupedCountries = $countries->groupedColumn(group: 'group', column: 'name', index: 'code');

$view = $app->get(ViewInterface::class);

$content = $view->render(view: 'countries/select', data: [
    'countries' => $groupedCountries,
]);

The views/countries/select.php view:

<?= $view->form()->select(
    name: 'countries[]',
    items: $countries,
    selectAttributes: [],
    optionAttributes: [],
    optgroupAttributes: [],
) ?>
/*
<select name="countries[]" id="countries">
    <optgroup label="Near By">
        <option value="FR">Frankreich</option>
        <option value="CH">Schweiz</option>
    </optgroup>
    <optgroup label="All Others">
        <option value="AF">Afghanistan</option>
        <option value="AX">Ålandinseln</option>
        <option value="AL">Albanien</option>
        ...
    </optgroup>
</select>
