hi ,

It would be really helpful.

register in the below link to get your api key

put below line in your gem file

gem ‘recaptcha’, :require => ‘recaptcha/rails’
put you api keys in config/environment.rb filr
ENV[‘RECAPTCHA_PUBLIC_KEY’] =
‘xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx’
ENV[‘RECAPTCHA_PRIVATE_KEY’] =
‘xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx’
you can verify recaptcha conditions in controller methods by
verify_recaptcha varible
ex:-
if !verify_recaptcha
#do operations
end

you can use `recaptcha_tags in any form

  for reference please go through the below link

`

can you tell me in which gem file i have to put this line

gem ‘recaptcha’, :require => ‘recaptcha/rails’

also, i have getting the public and private keys for live domain so shall those keys are used for

local environment also ? also i read on some site that

Download the zip file for the reCAPTCHA WordPress CAPTCHA plugin.
Unzip the recaptcha folder into your WordPress wp-content/plugins directory.

is this necessary ?
