Edit attendee data – warning line 677

Hi, I’ve just purchased a new licence, did an upgrade of my EE3 and now I am getting a warning message on the Edit Attendee Data page, top right corner, just above the Ticket Prices section.

it says:

Warning: count(): Parameter must be an array or an object that implements Countable in /homepages/30/d192640622/htdocs/hosting/ on line 677

I am using the latest version of WordPress.

Can someone please get back to me with a fix?

Many thanks,

Hi Roland,

That warning is basically saying the count() function was not passed an array or object that it count run on to return a value, it works as is but throws a warning to show ‘something’ isn’t right.

In this case, count isn’t needed and empty() can be used, so to fix this if you are comfortable with PHP you can change:


On line 677 will be something like:

<?php if (count($additional_attendees) > 0) { ?>

Change that to be:

<?php if (!empty($additional_attendees)) { ?>

Currently, EE3 is only receiving security updates (we do not have any currently), but as this is a simple localized fix I’ll create a ticket for this so it’s included on the next release if a security report comes in.
