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;
  }
