I am having problems creating a regex validator that checks to make sure the input has uppercase or lowercase alphabetical characters, spaces, periods, underscores, and dashes only. Couldn't find this example online via searches. For example:
These are ok:
Dr. Marshall
sam smith
.george con-stanza .great
peter.
josh_stinson
smith _.gorne
Anything containing other characters is not okay. That is numbers, or any other symbols.
This question is related to
regex
Check out the basics of regular expressions in a tutorial. All it requires is two anchors and a repeated character class:
^[a-zA-Z ._-]*$
If you use the case-insensitive modifier, you can shorten this to
^[a-z ._-]*$
Note that the space is significant (it is just a character like any other).
