uniqueSuffix

uniqueSuffix

If you want to use a different way of identifying uniqueness (other than auto-incrementing integers), you can set the uniqueSuffix configuration to a function or callable that generates the "unique" values for you.

The function should take three parameters: the base slug (i.e. the non-unique slug), the separator string, and an \Illuminate\Support\Collection of all the other slug strings that start with the same slug. You can then do whatever you want to create a new suffix that hasn't been used by any of the slugs in the collection. For example, if you wanted to use letters instead of numbers as a suffix, this is one way to achieve that:

'uniqueSuffix' => function ($slug, $separator, Collection $list) {
    $size = count($list);

    return chr($size + 96);
}
