[Phplib-users] OOHForms / valid_regex

[Uli L. <U....@Li...>]

Good morning List!

Im just trying to get some forms with OOHForms working (I hope this is not
off-topic). There is one Problem left:

I have a form, where I ask for adress, phone, e-mail an so on.

E-Mail is not required, but if the user fills out the E-Mail field, i want
to validate the e-mail. I do the validation with the regular expression:

[a-z0-9_-]+(\.[a-z0-9_-]+)*@([0-9a-z][0-9a-z-]*[0-9a-z]\.)+([a-z]{2,4}|museu
m)

The validation is OK. But what do I have to do, so that an empty E-Mail
field is also accepted?

Thank you all for your help!

Uli
