Set value to customer custom address attribute in magento2

Question

I have created a multi-select attribute(attribute_code is address_purpose) for the customer using UpgradeData

The options are created and the values are getting stored if I edit in magento admin.

But they are not updating once updated programmatically with addressId.

I have two Options Delivery, General.

So I am updating address using below code with the addressId.

  $addressPurpose = array("Delivery","General");
  $shippingAddressId = 15;
  $address = $this->_addressRepository->getById($shippingAddressId);  
  $address->setCustomerId(1);
  $address->setFirstname('test');
  $address->setLastname('test');
  $address->setCountryId('GB');
  $address->setPostcode('TW9 1AF');
  $address->setCity('Test');
  //$address->setData('address_purpose',$addressPurpose);
  //$address->setAddressPurpose($addressPurpose);
  $address->setCustomAttribute('address_purpose', $addressPurpose);
  $address->setTelephone('1213323213');

 $this->_addressRepository->save($address);

This code is not saving value for my custom attribute(address_purpose).

What is the problem here? Please, anyone support on this issue. Thanks

Answer 1

if you are saving multiselect attribute you have to store option id instead it's value

public function getAllOptions()
    {
        return [
           'option1' => [
            'label' => 'Delivery',
            'value' => 'delivery'
        ],
        'option2' => [
            'label' => 'General',
            'value' => 'general'
           ]
        ];
     }

$addressPurpose = array("option1","option2");
$address->setCustomAttribute('address_purpose', $addressPurpose);
$this->_addressRepository->save($address);

Answer 2

$address = $this->_addressRepository->getById($shippingAddressId); vs. $this->addressRepository->save($address);?

Variable once with leading underscore and once without. I suppose that's only a typo in your posting. The rest of the code seems to be ok and should save the custom attribute in my opinion.

I would suggest to debug data in the save method in AddressRepository especially what happens with your address data before and after $addressModel->updateData($address);
