Extending Invisible reCaptcha

Here are some useful hooks to help developers integrate Invisible reCaptcha with any plugin or custom form

Actions

- google_invre_render_widget_action - renders the recaptcha widget

Filters

- google_invre_is_valid_request_filter   - used to check if Google approved the request (returns bool true/false)
- google_invre_widget_output_html_filter - used to change the recaptcha widget output
- google_invre_language_code_filter      - used to change the badge/challenge language code
- google_invre_badge_position_filter     - used to change the badge position (possible returning values are: 'bottomright', 'bottomleft', 'inline')

Examples of using Invisible reCaptcha hooks

• Add Invisible reCaptcha into any form

  Just call
  do_action(‘google_invre_render_widget_action’);
  anywhere before form closing tag

• Validate form post request

  $is_valid = apply_filters(‘google_invre_is_valid_request_filter’, true);
  if( ! $is_valid )
  {
  // handle error here
  }
  else
  {
  // continue with your logic
  }

• Change the badge/challenge language code

  add_filter( ‘google_invre_language_code_filter’, ‘myprefix_change_recaptcha_language’ );
  function myprefix_change_recaptcha_language($language_code){
  $language_code = ‘fr’; // French
  return $language_code;
  }

NOVEMBER 2023 – DO NOT USE ANYMORE – It will put your website down. At first it seems that it still work but I found that it create errors later and my websites were down without warning. I used it for years but it seems impossible now !

Speed issues and no longer works

dualaudi June 21, 2023

<p>We use v2 recaptcha code + this plugin on a “all” of our sites with gravity forms. Unfortunately we have GF on the home page (for capturing leads) where this loads and it adds a bunch of bloat (granted from google). It would be nice if there was a way to optimize this so it didn’t load an additional 20-25 requests. </p> <p>Pros: drops spam considerably with gravity forms. Easy to implement.<br> Cons: slows your pagespeed scores down, can’t defer JS otherwise it may not work. Adds about 20 or more resources from google just to enable recaptcha v2.</p> <!– wp:paragraph –> <p>UPDATE – invisible captcha has not worked for a very long time. I don’t believe it’s a plugin issue, it’s just the captcha service does not really work anymore. Bots have figured a way around this.</p> <!– /wp:paragraph –>

after setup with keys it worked however shortly after the recaptcha no longer loads. not sure what the issue is as in the source I see the google code.

Plugin seems abandoned

ardsoms March 23, 2021

Thanks to this plugin not having been tested with the last 3 major WordPress updates, it managed to break my CF7 forms and Google Analytics form submission tracking from one day to the other. It looks like this plugin was abandoned, so I strongly advise against installing it. Unreliable!
