enter image description here

How can I populate this field so it's filled in when a customer creates an account? The value of the field just needs to match what customer[parent_customer_id] has. It doesn't necessarily have to happen on account creation.

enter image description here

The name of the field is customer[account_number]

This field is a duplicate but we call it something different and it populates correctly.

The name of that input is name="customer[parent_customer_id]"

Even though it's redundant I want both fields to populate. What file and where should I be editing to populate customer[account_number] in its respective field?

I just need the same default Attribute data that populates customer[parent_customer_id] to populate customer[account_number]

    Not a hundred percent sure but I believe this is a DB value so it needs to be through UpgradeData

If I understand your question correctly you just want to have another field (account_number) to populate the same value of customer attribute parent_customer_id.

For this you will need to create a NameSpace/YourModule/view/adminhtml/ui_component/customer_form.xml and have this content:

<form xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Ui:etc/ui_configuration.xsd">
    <fieldset name="customer">
        <field name="account_number" formElement="input">
            <argument name="data" xsi:type="array">
                <item name="config" xsi:type="array">
                    <item name="source" xsi:type="string">customer</item>
                <label translate="true">Account Number</label>
                <dataScope>firstname</dataScope><!--change this "firstname" to "parent_customer_id". My understanding is parent_customer_id is a customer attribute.-->

Hope this helps.

  • Yes, I had seen your image. You will need to add this in your ui_component XML file: <dataScope>parent_customer_id</dataScope> like I have got it in the answer. Mar 11, 2021 at 22:26
