also instead of count($app->module('collections')->find(...))
you can also use $app->module('collections')->count('aktuelles', ['slug' => $slug])
Changes with @aheinze suggestions:
(Just change the "XXX" occurrences with your collection name and "YYY" occurrences with the entry you want your slug to be based on)
<?php
// this is in the `/config` folder
// collection: XXX
// slug is created bt reading this field: YYY
$app->on("collections.save.before.XXX", function($YYY, &$entry, $isUpdate) use ($app) {
// generate slug on create only or when an existing one is empty
if (!$isUpdate || ($isUpdate && trim($entry['slug']) == '')) {
// generate slug based on defined entry
$slug = $app->helper('utils')->sluggify($entry['YYY']);
// count existing entires in collection with given $slug
$entries = $app->module('collections')->count('XXX', ['slug' => $slug]);
// if slug is existing already, postfix with incremental count
if ($entries > 0) {
$slug = "{$slug}-{$entries}";
}
$entry['slug'] = $slug;
}

instead of
Str::slug($entry['name'])you can also use the built-in sluggify helper function e.g$app->helper('utils')->sluggify($entry['name'])
