Re: using an array to propagate a CGI menu

in reply to using an array to propagate a CGI menu

The problem is that popup_menu demands a reference to an array, not an array.

There are two common ways of creating a reference to an array:

you quote the man page of CGI, where a reference to an anonymous array is used:

-values=>['a', 'b', 'c']

But what you want is to use an existing (named) array, and create a reference to it:

-values=>\@publication_categories

There's a lot about refernces in the standard perl documentation: perlre is about references, perldsc about various intresting data structures you can build with them.

[tye]: disable /proc and then see what it does?
[davido]: then it reads from /etc/passwd to decide who my uid is.
[davido]: sorry, typed that before you asked me to disable proc
[davido]: but you stumped me; don't know how to disable proc.
[tye]: I don't know if you can just dismount, but I thought so.
[davido]: yeah, umount -f isn't powerful enough.
[tye]: probably something in the init subsystem that does the mounting that you could disable and reboot.
