PHP Warning: Undefined variable $num_pastdue_actions

Hey,
We now get the same warnings. Although we don’t have installed WooCommerce.
Best regards

I also do not have woocommerce installed.

Hello @webhaus,

Thank you for contacting the support, and sorry for the inconvenience caused.

The notice is related to the updated ActionScheduler library that includes a new view in the actions list.

Please add the filter given below to your site to remove the notice:

add_filter( 'action_scheduler_pastdue_actions_check_pre', '__return_false' );

Here is how to add a filter to your site: https://rankmath.com/kb/wordpress-hooks-actions-filters/

Hope that helps. Let us know if you need any other assistance.

Ok, I understand that this filter is Rank Math specific and disables that particular functionality (those Action Scheduler warning notices) and that is the easy way out, but I’m talking about PHP warnings which are being generated, if we do not turn it off – and PHP warnings mean that the code has an unexpected scenario which needs to be fixed.

Once again I’m talking about this file:
wp-content/plugins/seo-by-rank-math/vendor/woocommerce/action-scheduler/classes/ActionScheduler_AdminView.php

The problem is that if the variable $num_pastdue_actions is only being set when the initial $check variable returns null, hovewer code in any case continues its execution below this check (on line 161) and on lines 191 and 194 tries to output a variable which is not set, resulting with a PHP warning.

The most simple way how you could avoid this warning, is by adding this small fix to the plugin just before the line 184 (contains comment: #Print notice):

if(!isset($num_pastdue_actions)) {
	$num_pastdue_actions = 0;
}

This will check if the variable is set or not, and will set it to 0, if it is not set. As without this fix the code returns 0 anyway in the notice, so the fix will not change anything except removing those two PHP warnings. I like to keep my error logs clean and I don’t want to disable this functionality.

Hello @webhaus

Thank you for your suggestion.

This is actually a bug in WooCommerce’s Action Scheduler package. We have opened an issue on their GH repo:
https://github.com/woocommerce/action-scheduler/issues/865

As soon as they will fix it, it will be fixed in the plugin as well.

Hope that helps.

Hello support team,
But why do we get this message, if we don’t have installed woocommerce?
Best regards

This is actually a bug in WooCommerce’s Action Scheduler package.

No, this is not, we’re facing a similar issue with our sites and they do not have WooCommerce installed at all. Please fix the warnings with the fix mentioned above.

Thanks!

Hello @tpmr and @itmedia24,

The bug is not in the main WooCommerce plugin or related to it. We use the Action Scheduler package of WooCommerce to schedule actions, and the bug is in that package. We have already opened an issue in their GH repo, which should be fixed soon.

We really appreciate your patience in the meantime.

Don’t hesitate to get in touch in case you need our assistance with anything else.

I have the same errors … even with Rank Math Pro. I see this thread was 3 months ago at this point. So you are saying this still has not been fixed in the action scheduler of woo commerce? Seeing rank Math PHP errors on every page is not a great confidence builder! @rankmathteam

Hello @sweetmariascom,

They haven’t yet fixed the issue, so the notices are visible on some setups. Please follow the steps mentioned here to fix the issue on your site:
