Re: drop down menus

If you use CGI.pm and IF you have assigned the values of the db in a hash named (for example) %myhash then what you want is :

start_form(-method=>'post', -action=>'youractionhere'),
popup_menu(-name=>'yournamehere', -values=>\%hash),
end_form;
[download]

you may also use a 'default' value. (man CGI.pm and look for popup_menu). Needless to say that the above code won't work on its own (it needs a new CGI and much more code, which I guess you know how to create).

-values needs an array reference (not an hash) so the right sintax is `-values=>[sort keys %hash]` [download]	[reply] [d/l]

Sorry, you're simply wrong.. What he needs is a hash reference: I copy/paste from the CGI.pm documentation: (in http://stein.cshl.org/WWW/software/CGI/cgi_docs.html) If you pass a HASH reference, the keys will be used for the menu values, and the values will be used for the menu labels.	[reply]

no, we are both right:-) (from http://stein.cshl.org/WWW/software/CGI/cgi_docs.html) The required second argument (-values) is an array reference containing the list of menu items in the menu. You can pass the method an anonymous array, as shown in the example, or a reference to a named array, such as \@foo. If you pass a HASH reference, the keys will be used for the menu values, and the values will be used for the menu labels (see -labels below). using an array reference has a little advantage: you have full control on how items are sorted...
