Re: Input arrays to CGI

if you just name them all the same thing "name='item'" then when you do $q->param('item'); you will get a reference to a list containing all the values (no clue what order tho)

I haven't used that functionality. Nice. Upon inspection though, I see that when called in scalar context, param('list') returns the first item only. In list context it works, returning an array of the values of all fields named 'list'. `http://localhost/somefile.cgi?list=1&list=2&list=666 $list = param('list'); # $list is 1 @list = param('list'); # @list is (1, 2, 666)` [download] With a list of checkboxes though, say for delete selection in a data table, I'd still have to use the `map {/list_(.)/}, param()` trick, because I'd have to know which* fields are checked. Thanks for pointing that one out BUU	[reply] [d/l] [select]

http://localhost/somefile.cgi?list=1&list=2&list=666

$list = param('list');
# $list is 1
@list = param('list');
# @list is (1, 2, 666)

With a list of checkboxes though, say for delete selection in a data table, I'd still have to use the map {/list_(.*)/}, param() trick, because I'd have to know which fields are checked.
