Select Box Options

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hello Monks, I am selecting more than one option in the select box and retrieving in the submit page as
my $userID = param('users');
This works fine for if I select only one option.
If I select more than one then I can only see first option.
What could be reason.Please advise
Thanks

Your select box options can be retrieved in array context. Try: `my @choices=param('selectbox'); print join ' ', @choices;` [download]	[reply] [d/l]

You need to call param in list context: `my @userIDs = $query->param('users')` See the CGI docs for more info.	[reply] [d/l]

From cgi.pm doc: `@values = $query->param('foo'); -or- $value = $query->param('foo');` [download] Pass the param() method a single argument to fetch the value of the named parameter. If the parameter is multivalued (e.g. from multiple selections in a scrolling list), you can ask to receive an array. Otherwise the method will return a single value.	[reply] [d/l]
