Edit a single address in Commerce

Question

I've read the docs but I can't seem to get this to work properly. I want to edit a single address on a separate page from where all addresses for a customer are listed. I have the link to the edit page, which looks like this:

<a href="{{ url('account/edit-address') }}?addressId={{ address.id }}">Edit</a>

Then on that edit-address template I have the following:

{% set addressId = craft.request.getParam('addressId') %}

<form method="post">
    {{ getCsrfInput() }}
    <input type="hidden" name="action" value="commerce/customerAddresses/save">
    <input type="hidden" name="redirect" value="account/address-book">

    {% if addressId %}
        <input type="hidden" name="address[id]" value="{{ addressId }}">
    {% endif %}

    <input type="text" name="address[firstName]" value="{{ address ? address[firstName] : '' }}">
    <input type="text" name="address[lastName]" value="{{ address ? address[lastName] : '' }}">
</form>

That leads to a "Variable 'address' does not exist" error. I understand why I get that error but I'm not sure how to get the value field to show the address info. Having a blank form field isn't going to cut it.

Answer 1

Are you looking for something like this? The second example will ensure an address variable exists, even if it is set to null.

{% set address = craft.commerce.customer.address(addressId) %}

or

{% set address = address is defined ? address : null %}

As for accessing the data, you would just do this:

{{ address ? address.firstName : '' }}

Another way to do it (without needing to define a null address variable) is:

{{ address.firstName ?? '' }}
