When a form is submitted, such as the one below:

<% form_tag do %>
  <label for="first_name">First Name:</label>
  <%= text_field_tag :first_name %>
<% end %>

a params hash is set so you can easily access its values in your controller, like so:

value = params[:first_name]

Just use the params hash in the controller, like so:

def update
  field_value = params[:field_name_here]
end
