Adding default Billing Address to User Listing

-- HikaShop version -- : 4.01
-- Joomla version -- : 3.6.5
-- PHP version -- : 7

To help identify customers when they call us it would be useful to see Post Codes (or some part of their address) on our back-end User Listing. We could then more quickly find which "Mr Smith" (who has forgotten their username or email address) for instance.

To do this I guess I need to adapt the file listing.php in view user.
Is there any simple way to show the default billing post code for a user?

Something as easy as <?php echo $row->user_email; ?> but for Town, City or Post Code instead?

That would be really helpful, but I bet not quite that simple...

That's a big help Nicolas, Thank you.

I squeezed in an extra column (etc) and added...
<td><?php
$addressClass = hikashop_get('class.address');
$addresses = $addressClass->get($row->user_id);
echo $addresses->address_post_code;
?>
</td>
Not sure why reset() was suggested - I did need to remove that for anything to show.
But the postcodes shown are not those of each user - often a postcode of the previous user shows instead.

If you have a little time attached is my complete file - I can't see where the loop doesn't pick up the correct user...

Appreciated Nicolas - do you mean like this?

$addressClass = hikashop_get('class.address');
$addresses = $addressClass->getByUser($row->user_id);
echo $addresses->address_post_code;

Unfortunately that doesn't work.

Thank you so much Nicolas!
Once again, superb support and tolerance of an idiot at this end.
Much appreciated and much learned!

It would be even more useful to add this extra address column to the array for search, on this override. But I am unsure how to do that.

To search include the address_post_code would be very useful.

At the moment for that table cell the code is:

<td><?php 
				$addressClass = hikashop_get('class.address');
				$addresses = $addressClass->getByUser($row->user_id);
				echo reset($addresses)->address_post_code;
				?>
           </td>

Merci Jerome
That looks beyond me, unless I find a darkened room for a couple of days!

I had hoped that adding strings for search happens on the Table Header rows during $this->pageinfo->filter->...etc statement.
But I recognise my naivety. Thanks for looking.
