I'm working with Laravel and I have used this custom regular expression for validating user password request:
'user_password'=> ['required','min:6','regex:/[a-z]/','regex:/[A-Z]/','regex:/[0-9]/','regex:/[@$!%*#?&]/']
Now I needed to combine these separated regexs all together but don't know how to do it, so if you know, please let me know.. thx!
One general way to do this via a single regex would be to use positive lookaheads to assert each requirement:
/^(?=.*[a-z])(?=.*[A-Z])(?=.*[0-9])(?=.*[@$!%*#?&]).{6,}$/
The above pattern says to match:
^ from the start of the user password
(?=.*[a-z]) at least one lowercase letter
(?=.*[A-Z]) at least one uppercase letter
(?=.*[0-9]) at least one digit
(?=.*[@$!%*#?&]) at least one special character
.{6,} then match any 6 or more characters
$ end of the password
