Question

Like in title – I’ve got a tag (no model) based form (form_tag) and I want after submit obtain values entered in fields of that form – how can I do it?

Answer 1

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]
