Custom Fields - password "Regular Expression Validation String"

[hideipvpn]

Hello all,

 

I have problems with "Regular Expression Validation String" for password custom field.

 

The password must be at least 6 characters long - max 12, must allow letters and numbers.

I think I solved my problem.

 

Here is my password validation string: [0-9a-zA-Z]{6,12}

Hello,

 

I need empty field or 11 char number.

 

Currently I'm using this: [0-9]{11}

 

But user can't continue with registration if this custom filed is empty.

So i need option to allow empty field or 11 numbers.

 

I doesn't understand regexp very well so i need help.

 

Tnx

[Miron]

Anyone?

 

Little bump.
