anyone know how to show mutiple recaptcha in one page about recaptcha

[AxisOfEval]

I can't imagine a use case for this. The primary function is to stop robots from submitting forms. For that, one captcha per page is good enough.

Actually I had similar problem: on one page I had two forms (one to send email to friend recommending current page, other to send us opinion about page). Both forms should have been secured from bots.
The problem is recaptcha don't play well in such scenario. The workaround is to display recaptcha just before submitting the form.

My solution
Add recaptcha_tags wrapper which display recaptcha only if current form is submitted (additionaly check if current form object has any errors - in such case also delay displaying recaptcha).
In application_helper.rb:

def recaptcha_tags(options = {})
    form = options.delete(:form)
    form_path = form ? form.options[:url] : options.delete(:path)
    form_object = form ? form.object : options.delete(:object)
    raise 'Form (Form builder object) or path (form path) option for recaptcha_tags is required' unless form || form_path
    options[:display] ||= {}
    options[:display][:lang] ||= I18n.locale.to_s
    this_form_sent = request.method != 'GET' && form_path == request.path
    form_without_errors = form_object.nil? || begin
      errors = form_object.errors.dup
      errors.delete(:base); errors.delete(:recaptcha)
      errors.empty?
    end
    content = if(this_form_sent && form_without_errors)
      warning = if form_object && form_object.errors.include?(:recaptcha)
        content_tag(:p, content_tag(:strong, form_object.errors[:recaptcha].first), class: 'text-danger')
      else ''.html_safe end
      super + warning
    else ''.html_safe end
    content_tag(:div, content, class: 'recaptcha')
  end

You have to pass :form (form builder object) or :path (form path) options to properly identify current form.

In application_controller.rb:

def verify_recaptcha options={}
    if params[:recaptcha_response_field].blank? && options[:model]
      attribute = options[:attribute] || :base
      options[:model].errors.add attribute, I18n.translate('recaptcha.errors.empty_response') || 'Enter text from image'
      false
    else
      super
    end
  end

As a extra step you can add this coffescript snippet to remove recaptcha from other forms (if current form has recaptcha, and recaptcha is also present on other form(s)) - as I said recaptcha doesn't play well when put in multiple places on site:

$ ->
  $(document).on 'submit', 'form', ->
    $('form').not(this).find('.recaptcha').remove()
    return true

If you use your imagination like @Gee-Bee has, then there are certainly use cases for multiple reCAPTCHA on a page.

Google has docs on how to do this with v2. https://developers.google.com/recaptcha/docs/display So there is a little manual work you need to do because it isn't part of this gem as of yet.

I followed their example and used 'sitekey' : "<%= Recaptcha.configuration.public_key %>", in the erb for the js.

Maybe @ambethia will integrate the ability to do this at some point. But for now I'm fine doing it mostly manually.

Having an example of this I the documentation would be awesome.

@ambethia I submitted a PR with the example. Since you have not accepted it, is it not what you were wanting/thinking?

[pandu-49-zz]

@bfcoder Your solution may work perfectly. Is there any solution with gem helper functions?

[ambethia]

@bfcoder I'm showing that PR as merged?

[bfcoder]

@ambethia It was merged, but subsequently removed in #146 Not sure why @grosser decided it was not needed anymore.

[grosser]

moved it to the wiki since it's an edge-case usecase that not everybody
needs to read about ... still linked in the readme
