My question is similar to this one but for a Rails app.
I have a form with some radio buttons, and would like to associate labels with them. The label
form helper only takes a form field as a parameter, but in this case I have multiple radio buttons for a single form field. The only way I see to do it is to manually create a label, hard coding the ID that is auto generated for the radio button. Does anyone know of a better way to do it?
For example:
<% form_for(@message) do |f| %>
<%= label :contactmethod %>
<%= f.radio_button :contactmethod, 'email', :checked => true %> Email
<%= f.radio_button :contactmethod, 'sms' %> SMS
<% end %>
This generates something like:
<label for="message_contactmethod">Contactmethod</label>
<input checked="checked" id="message_contactmethod_email" name="message[contactmethod]" value="email" type="radio"> Email
<input id="message_contactmethod_sms" name="message[contactmethod]" value="sms" type="radio"> SMS
What I want:
<input checked="checked" id="message_contactmethod_email" name="message[contactmethod]" value="email" type="radio"><label for="message_contactmethod_email">Email</label>
<input id="message_contactmethod_sms" name="message[contactmethod]" value="sms" type="radio"> <label for="message_contactmethod_sms">SMS</label>
Passing the :value
option to f.label
will ensure the label tag's for
attribute is the same as the id of the corresponding radio_button
<% form_for(@message) do |f| %>
<%= f.radio_button :contactmethod, 'email' %>
<%= f.label :contactmethod, 'Email', :value => 'email' %>
<%= f.radio_button :contactmethod, 'sms' %>
<%= f.label :contactmethod, 'SMS', :value => 'sms' %>
<% end %>
See ActionView::Helpers::FormHelper#label
the :value option, which is designed to target labels for radio_button tags
