如何获得 Magento 2 Country Collection

如何解决如何获得 Magento 2 Country Collection

希望你一切顺利。

我想以以下格式获取所有国家/地区。

$countries = [
  "AU" => "Australia","IN" => "India","US" => "United States","UK" => "United Kingdom",.......
]

我尝试过但没有用，我总是将 CountryId 设为 2 位数字名称，例如

$countries = [
  0 => "AU",1 => "IN",2 => "US",3 => "UK",.......
]

我使用了以下代码

Magento\Directory\Model\ResourceModel\Country\Collection::loadByStore()

我如何在 Magento 2 中实现这一点？

提前致谢。

解决方法

我认为您需要遍历国家/地区集合并创建一个以国家/地区代码为键、以国家/地区名称为值的新数组。你可以试试这样的吗？

public function __construct(
    \Magento\Backend\Block\Template\Context $context,\Magento\Directory\Model\ResourceModel\Country\CollectionFactory $countryCollectionFactory,\Magento\Directory\Model\CountryFactory $countryFactory,array $data = []
) {
    $this->countryCollectionFactory = $countryCollectionFactory;
    $this->countryFactory = $countryFactory;
    parent::__construct($context,$data);
}


public function getCountryName($countryCode){
    $country = $this->countryFactory->create()->loadByCode($countryCode);
    return $country->getName();
}

public function getCountryCollection()
{
    $collection = $this->countryCollectionFactory->create()->loadByStore();
    return $collection;
}

public function getCountries()
{
    $countryCollection = $this->getCountryCollection();

    $countries = [];
    foreach ($countryCollection->getData() as $country) {
        $countries[$country['country_id']] = $this->getCountryName($country['country_id']);
    }

    return $countries;
}

然后在您的模板中，您可以使用 $block->getCountries() 获取国家/地区。

结果：

array(249) { ["AD"]=> string(7) "Andorra" ["AE"]=> string(28) "Verenigde Arabische Emiraten" ["AF"]=> string(11) "Afghanistan" ["AG"]=> string(18) "Antigua en Barbuda" ["AI"]=> string(8) "Anguilla" ["AL"]=> string(8) "Albanië" ["AM"]=> string(8) "Armenië" ["AN"]=> NULL ["AO"]=> string(6) "Angola" ["AQ"]=> string(10) "Antarctica" ["AR"]=> string(11) "Argentinië" ["AS"]=> string(16) "Amerikaans-Samoa" ["AT"]=> string(10) "Oostenrijk" ["AU"]=> string(10) "Australië" ["AW"]=> string(5) "Aruba" ["AX"]=> string(6) "Åland" ...

使用我的简单代码：（可以ez注入类）

    public function getCountries()
    {
        /** @var \Magento\Directory\Model\ResourceModel\Country\CollectionFactory $countryCollectionFactory */
        $countryCollectionFactory = $this->_objectManager->get(\Magento\Directory\Model\ResourceModel\Country\CollectionFactory::class);

        /** @var \Magento\Directory\Model\ResourceModel\Country\Collection $countryCollection */
        $countryCollection = $countryCollectionFactory->create();

        $countryCollection = $countryCollection->toOptionArray();

        return array_column($countryCollection,'label','value');
    }
