Widget generates error with upgrade to WP 5.3

I have the same error. Looking forward to hearing any suggestions!

Same here.

You may try to edit two lines with the same content in these two files:
/plugins/extended-categories-widget/4.2/class/avh-ec.widgets.php line 62
/plugins/extended-categories-widget/4.2/class/avh-ec.core.php line 876

Change both lines from:
public function walk($elements, $max_depth) {
to:
public function walk($elements, $max_depth, …$args) {

The warning will be gone, please test if the plugin still works as desired.

Thank you for the suggestion, but it feels like we’re doing your work for you. Doesn’t it mean it’s time for an update to your plugin?

Don’t blame me. It’s not my plugin, i just stumbled over the same problem, found your question by googling it, then tried to solve it by myself and wanted to share my solution. You’re welcome.

Oops, sorry! Thanks for trying to help out!

Thanks for helping out, but your suggestion does not work for me. By the way, is this valid PHP syntax?

…$args

Have never seen this before, and my code editor throws an error.

Thank you for your post!!!
When I pasted your correction it did not work.
When I manually typed in the following it did work.
public function walk($elements, $max_depth, …$args) {

Hi aaron, thanks for your feedback.
Sorry, on the way from my tested code to my posting here the three dots ... before $args were somewhere replaced by an ellipsis … – looks similar, but is as wrong as a greek question mark instead of a semicolon (the classic prank).

And yes, with three dots it is valid PHP, see https://www.php.net/manual/en/functions.arguments.php#functions.variable-arg-list

Edit: just learned that the CODE-Tag in the editor here prevents the three-dots-replace.
Change both lines from:
public function walk($elements, $max_depth) {
to:
public function walk($elements, $max_depth, ...$args) {

• This reply was modified 5 years ago by cyrfer. Reason: The editor here replaced three dots with ellipsis where the dots are essential

Thanks again. Made the same mistake. Now, it’s working. Code editor still shows a syntax error. Well, who cares!

Thanks for helping out, buddy!

Is there any way we can encourage Peter van der Does, the author of this great plugin, to update it?

WordPress reads, “Last updated:3 years ago”.

Worked like a charm, with manually typing ‘…’. Thanks all, especially @cyrfer! And sorry again for my misunderstanding. :-/

Thank you @cyrfer for your solution, works fine now!

thank you @cyrfer – much appreciated

Thanks!
