Morning all, would anyone be able to explain this regular expression:
/^[\w ,.!?\-'"\(\)\s]+$/
I'm going to read up on it but I'm in a hurry for this.
Everything inside [] defines a character class which is a list of
characters,
any one of which can match a single character in the string and which includes
the \w and \s character classes. The regular expression says to match at the
beginning of the string one or more of any characters in the character class
to the end of the string. The purpose is to determine if the string contains
ONLY the characters in the character class.
