regular expression

[thomasp]

Can I use a regular expression to test if the entered value is a 4,6,8 or 10
digit number.
If so, could you write a quick example?

1234
123456
12345678
1234567890

It can only be 4,6,8, or 10 digits long and must be all numbers. No
decimals, signs, or spaces.

Thanks,

Thomas

This will match only numbers with 4 digits.

^[0-9]{4}$

I couldn't find out how to say 4 or 6 or 8 or 10

How about

^(\d\d){2,5}$

that is, 2 3 4 or 5 groups of two digits.

This will match only numbers with 4 digits.

^[0-9]{4}$

^[0-9]{4}$
^[0-9]{6}$
^[0-9]{8}$
^[0-9]{10}$
