I want something like this:
<%= f.hidden_field :ids, :multiple => true, :value => array %>
but it's not saving anything. Am I doing anything wrong or is there another way to approach this?

try this
<% array.each do |a| %>
<%= f.hidden_field :ids, :multiple => true, :value => a %>
<% end %>
some says this wont work in rails 4
<%= f.hidden_field :ids, :multiple => true, :value => a %>
replace that with this incase it wont work for you
<%= f.hidden_field "ids[]", value: a %>
or you can try using hidden_field_tag as well.. if you can access without object
<% array.each do |a| %>
<%= hidden_field_tag "ids[]", a %>
<% end %>
and in controller you can access using this params[:ids]

I tried this exactly and it does not seem to be working. After submitting the form, :ids has a null value.

try this
<%= f.hidden_field "ids[]", value: a %> inside loop. im hoping it will work.Athar
i just tested this
<% (0..10).each do |a| %> <%= f.hidden_field :ids, :multiple => true, :value => a %> <% end %> in my project with user model and i fetch from params like this params[:user][:ids] im using rails 4.2.0Athar
im going to try this now
<%= f.hidden_field "ids[]", value: a %>Athar
added option hidden_field_tag as well and you can access using params[:ids] in controller
