How to get all selected rows in the mutli-selection listbox?

Rails
1

Hi,

I have created a multiple selection listbox with
rails, when I try to get the rows selected by user,
rails send back only the first one, how can I get the
other selected rows???

I created the listbox with the following function:

select_tag(“form__list1”,
options_for_select([“A”,“B”,“C”,“D”], selected = “A”),
html_options = {“size” => 5, “multiple” => true})

What I get from params is :

!map:HashWithIndifferentAccess
commit: Next
action: index
controller: cellfiles
form__list1: “A”

Thanks you very much

select_tag(“form__list1[]”,
…

hmm you might need to do something like form_list1[] instead of just
form_list1 to get all the values into an array.

try that

Saiho,

Try this:

select_tag(‘letters[]’, options_for_select([‘A’,‘B’,‘C’,‘D’], ‘A’),
:size => 5, :multiple => true)

You need to add the [] to the name to get back an array of selected
values.
