The rule is a bit different than I thought. I wasn't able to find it now in this topic, can you help me?
It would also be nice to have a tiny bit of PHP (or whatever) that allows for an input field, and converts a number into an URL.
Examples
I made a rule that if the length is <= than 4, the folder would be 0. And if the length is > 4 the folder is the first 3 digits.
As 178336 has 6 digits, the script is redirecting it to a 3 digits folder.
When should the folder have only the first 2 digits?
