I built a Magento 2 custom module for shipping that has a select drop down field for users to choose an option. I want to be able to set those options in the admin for the module using the dynamic row system. I have the form built and working. This is the section for the select box using:

frontend>layout>checkout_index_index.xml

<item name="checkout_building_address" xsi:type="array">
 <item name="component" xsi:type="string">Magento_Ui/js/form/element/select</item>
 <item name="config" xsi:type="array">
 <item name="customScope" xsi:type="string">customCheckoutForm</item>
 <item name="template" xsi:type="string">ui/form/field</item>
 <item name="elementTmpl" xsi:type="string">ui/form/element/select</item>
 </item>
 <item name="options" xsi:type="array">
 <item name="0" xsi:type="array">
 <item name="label" xsi:type="string">Please select value</item>
 <item name="value" xsi:type="string"></item>
 </item>
 <item name="1" xsi:type="array">
 <item name="label" xsi:type="string">Option 1</item>
 <item name="value" xsi:type="string">value_1</item>
 </item>
 <item name="2" xsi:type="array">
 <item name="label" xsi:type="string">Option 2</item>
 <item name="value" xsi:type="string">value_2</item>
 </item>
 </item>
 <item name="value" xsi:type="string">Please Select Value</item>
 <item name="provider" xsi:type="string">checkoutProvider</item>
 <item name="dataScope" xsi:type="string">customCheckoutForm.checkout_building_address</item>
 <item name="label" xsi:type="string">Select Building Address</item>
 <item name="sortOrder" xsi:type="string">2</item>
 </item>

I also followed the Mage docs for getting the dynamic rows in the admin. That is working fine and saves the information to the core_config_data table as a serialized array.

"_1564590939871_871":"addresses":"123 Amy Street Any Town, CA 92234","_1564593462830_830":"addresses":"1475 Main St. Any Town, CA 90210"

I cannot figure out how to get that data to populate the select box in my form.

Thanks in advance for the help!

***** UPDATE *****
I am now using this in Helper>Data.php

public function getJsonConfigValue($configPath, $store = null)
 
 $value = $this->getJsonConfigValue($configPath, $store);

 if (empty($value)) return false;

 if ($this->isSerialized($value)) 
 $unserializer = ObjectManager::getInstance()->get(MagentoFrameworkUnserializeUnserialize::class);
 else 
 $unserializer = ObjectManager::getInstance()->get(MagentoFrameworkSerializeSerializerJson::class);
 

 return $unserializer->unserialize($value);
 

and I can see that data in a template using:

public function getJsonSerialized()
 
 $arrayItems = $this->helper->getJsonConfigValue('carriers/dynamic/addresses/address_list');

 return json_encode($arrayItems);
 

And this in a template file view>frontend>templates>array.phtml

<?php echo $block->getJsonSerialized(); ?>

And it appears like this on the page:

"_1564763325005_5":"addresses":"123 My Street, Bldg. 1, My Town, IA 00351"

How do I turn it into something that I can use in a form I built in a custom module to populate the select drop down field?

It this my problem? - return json_encode($arrayItems);

I can't find what I think I am looking for.

Thanks!

***** UPDATE 2 *****

This is part of the test XML to get the box on the page for the module.

view>frontend>layout>checkout_index_index.xml

<item name="checkout_building_address" xsi:type="array">
 <item name="component" xsi:type="string">Magento_Ui/js/form/element/select</item>
 <item name="config" xsi:type="array">

 <item name="customScope" xsi:type="string">customCheckoutForm</item>
 <item name="template" xsi:type="string">ui/form/field</item>
 <item name="elementTmpl" xsi:type="string">ui/form/element/select</item>
 </item>
 <item name="options" xsi:type="array">
 <item name="0" xsi:type="array">
 <item name="label" xsi:type="string">Please select value</item>
 <item name="value" xsi:type="string"></item>
 </item>
 <item name="1" xsi:type="array">
 <item name="label" xsi:type="string">Option 1</item>
 <item name="value" xsi:type="string">value_1</item>
 </item>
 <item name="2" xsi:type="array">
 <item name="label" xsi:type="string">Option 2</item>
 <item name="value" xsi:type="string">value_2</item>
 </item>
 </item>
 <item name="value" xsi:type="string">Please Select Value</item>
 <item name="provider" xsi:type="string">checkoutProvider</item>
 <item name="dataScope" xsi:type="string">customCheckoutForm.checkout_building_address</item>
 <item name="label" xsi:type="string">Select Building Address</item>
 <item name="sortOrder" xsi:type="string">2</item>
</item>

I used Api>Data>CustomFieldsInterface.php to get the data from XML

interface CustomFieldsInterface
null
 */
 public function getCheckoutBuildingAddress();

 /**
 * Set checkout buyer name
 *
 * @param string

From there I get it into to show in the frontend, order and the admin. Instead of using the dummy values I used in the XML file I need to replace it with the data from the array.
