Regex Validation help

[CarrieM]

Hi

I would like to restrict the text users can enter so it's in the format S####, eg S0005. Is this possible?

Thanks

@CarrieM

You can try the following, that should ensure it starts with an 'S' followed by four numbers.

[S][0-9]{4}$

Cheers

Martyn

@CarrieM I always use Regex101 for testing this kind of thing, it shows you what matches, explains the match string (see below), and has a searchable list of tokens to help you work out how to construct it.

It's made me look a lot better at regex than i really am on a number of occasions!
