Question

I’m trying to get a regular expression that allows between 6 – 15 characters and can be a-zA-Z0-9 and the symbols above the numbers 1–8 on a keyboard.

Here’s what I have but it doesn’t work.

'/^[a-zA-Z0-9-_][\!\@\#\$\%\^&\*]{5,16}+$/'

Answer 1

you have two different sets within brackets. Basically the expression says “1 of a-zA-Z0-9-_” followed by 5-16 of special characters. Combine them into the same set of brackets and you’re all good.

Something like the following:

'/^[a-zA-Z0-9-_\!\@\#\$\%\^&\*]{5,16}$/'
