Override the unordered list for tweets

add_filter( 'latest_tweets_render_list', function( array $items, $screen_name ){
   // process $items array
    return '<div>....your html</div>';
}, 10 , 1 );

Thanks, in my case something as simple as the below works:

add_filter( 'latest_tweets_render_list', function( array $items, $screen_name ){
	// process $items array
	foreach ($items as $item) {
		$out .= $item;
	}
    return $out;
}, 10 , 1 );

However I am also getting an error:

Warning: Missing argument 2 for {closure}()

The $screen_name argument should always be passed, but perhaps if it is null it doesn’t for some reason.

You can see the filter being called here:
https://github.com/timwhitlock/wp-twitter-widget/blob/master/latest-tweets.php#L275

Try removing the $screen_name argument if you’re not using it. Or just put $screen_name = null in your argument list.

I am using screen_name, it’s set in the widget.

However if I echo it from within the filter it’s empty…

But you are right removing the argument all together or setting $screen_name = null in the argument list works.

I no longer get a warning yet the tweets are still being returned for the correct account.

Thanks for your help.
