Magento 2 : How to get Select Options in Template from Attribute Source Model

Question

I created a custom attribute for customer entity, with options from another db_table

I want to display this field as a select item (with options from source model) in the registration page (customer_account_create)

I created all the needed files but i don't know how to get the options (created in source model) in the template file

Here is all the created/needed files:

InstallData Vendor/Module/Setup/InstallData.php

    <?php

namespace Vendor\Module\Setup;

use Magento\Customer\Setup\CustomerSetupFactory;

<fieldset class="fieldset create account" data-hasrequired="<?php /* @escapeNotVerified */ echo __('* Required Fields') ?>">

   <!-- Need select item for testField customer attribute -->
   <!-- Options from db_table (in source model)-->
   ............................................................


</fieldset>

Could any one help me how to get this select options in template ?

Answer 1

use Magento\Eav\Model\Config as EavConfig;

protected $eavConfig;


public function __construct(
    ...
    Config $eavConfig
    ....
) {
    ....
    $this->eavConfig = $eavConfig;
    ....
}

Now you can load your attribute like this,

$yourAttribute=$this->eavConfig->getAttribute('customer','YOUR_ATTRIBUTE_CODE');

if($yourAttribute->getSource()){
    $options = $yourAttribute->getSource()->getAllOptions();
}

---

Using ObjectManager (Not recommended)

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$yourAttribute = $objectManager->create('Magento\Eav\Model\Config')->getAttribute('customer','YOUR_ATTRIBUTE_CODE');

if($yourAttribute->getSource()){
    $options = $yourAttribute->getSource()->getAllOptions();
}
