I'm not trying to pre-populate the text area.
I just want to get the input from the user and make sure he can
only insert chars that I allow. The only char I have a problem with
is the " (Quote). If I enter a " into the text area the regexp bellow
does not allow it in.
preg_match("/^[à-úA-Za-z0-9_():,@\/\.\s\"- ]*$/i",$FieldValue) - Fails
preg_match("/^[à-úA-Za-z0-9_():,@\/\.\s\\"- ]*$/i",$FieldValue) (This one gives a php error cause the \\" closes the opening ")
preg_match('/^[א-תA-Za-z0-9_():,@\/\.\s"- ]*$/i',$FieldValue) - Fails
preg_match('/^[א-תA-Za-z0-9_():,@\/\.\s\"- ]*$/i',$FieldValue) - Fails
preg_match('/^[א-תA-Za-z0-9_():,@\/\.\s\\"- ]*$/i',$FieldValue) - Fails
So how can I allow a quote (") to be a valid char?
thanks
berber

Fails in what way?
Are you sure you are remembering to do http://php.net/htmlentities on the data you send out for the TEXTAREA to pre-populate it?
Does PCRE need " escaped inside the [] bit? I think not, but I suppose \\" instead of \" couldn't hurt.
You may also want to move the - to the end of [] character set and lose the \, just to keep it simpler.
