help with reg expression

[wo1olf]

Here is the reg expression i'm using to validate a field form.
"^[-a-z ,é,ç,è,à,â,ê]+$"
I want it also to include the character " ' "
How can i do that ?

"^[-a-z ,é,ç,è,à,â,ê']+$"

[wo1olf]

"^[-a-z ,é,ç,è,à,â,ê']+$"

You don't need to put a comma between letters/numbers/whatever inside character classes in regular expressions.

Like this:

/^[-a-z éçèàâê']+$/

Also, that should match '. If it doesn't then something else is wrong. Try using an online regular expression checker like http://www.nvcc.edu/home/drodgers/ceu/resources/test_regexp.asp
