What you're missing is you need to escape the special characters that have meaning to a regular expression. Such as parenthesis, dashes and slashes.

\([a-zA-Z0-9\-\/]+\)

If you need to force that the string is nothing but this then make it looks like this:

^\([a-zA-Z0-9\-\/]+\)$

The ^ and the $ mean it must start and end with this respectively.

Broken down:

^ = Must start with
\( = An opening parenthesis
[a-zA-Z0-9\-\/]+ = At least one or more alphanumeric chars, dashes or forward slashes
\) = A closing parenthesis
$ = Must end with

You can use this regex:

^\([A-Za-z0-9\-\/]+\)$

You need to escape parentheses and put slash and dash into your character set. ^ and $ is optional if you want to match the string from the beginning to end.
