Question

I seem to have backed myself up into a corner with this. I’m sure that the answer is going to make me want to smack a brick against my head, but I’m not all that good with regex just yet. So, here goes.

I need to modify this regex so that it fails if it finds any occurances of pound signs. (#)

My current regex is this;

/^[A-Za-z\.\-\_\s]{1,80}$/i

I tried a number of variations such as;

/[^#]^[A-Za-z\.\-\_\s]{1,80}$/i
/^[[^#]A-Za-z\.\-\_\s]{1,80}$/i
/^[A-Za-z\.\-\_\s^#]{1,80}$/i

None of which work. Can anyone offer any advise, please?

Answer 1

Your original regex should work, because # isn’t in the list of characters you specified for the class. You don’t need to add anything, it already fails if there’s a # in there.
