Help with RegEx validation ...

[contiw]

So far I have this regex code

/[^a-z\-\,\']|(\,.*\,)$/

which should check if a string is:
contains just alpha nocase,
one or more single spaces allowed,
apostrophe and dash allowed,
just one comma allowed

Unfortunately it doesn't work.
Any help cordially appreciated.

when you put the "^" inside the brackets, that meanse NOT. so your expression would NOT match a-z, -, and '

try this:

/^[a-z\-\,\'](\,.*\,)$/

i'm not 100% on if all those characters need to be escaped, but that should at least get you on the right track.
