popup_menu creates a menu.
-
The required first argument is the menu's name (-name).
-
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''.
-
The optional third parameter (-default) is the name of the default menu
choice. If not specified, the first item will be the default. The values of
the previous choice will be maintained across queries.
-
The optional fourth parameter (-labels) is provided for people who want to
use different values for the user-visible label inside the popup menu nd
the value returned to your script. It's a pointer to an associative array
relating menu values to user-visible labels. If you leave this parameter
blank, the menu values will be displayed by default. (You can also leave a
label undefined if you want to).
When the form is processed, the selected value of the popup menu can be
retrieved using:
$popup_menu_value = $query->param('menu_name');
