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;
    }

Note: This plugin requires PHP 5.3 or higher to be activated.

Reviews

Works great

Is very easy to setup, and works everywhere.

The only thing i would recommend is to add instructions of how create recaptcha keys (an link would help) and maybe an recaptcha generator (maybe something on recaptcha api – iframes, etc).

Another thing, add an custom message for contact form 7 when it fails because of recaptcha.

Could broke your login and site if you are not careful

It seriously broke my login and register forms.

I couldn’t login to my wordpress site due to an error and I couldn’t disable it because I was logged out, so I had to use my other google accounts using the “google login” button I had added just before (thank god!!!). Otherwise my blog would be all broken and with no way to disable this plugin. That’s pretty serious! Be sure you have other ways to login if you install this!!!!

Simple setup, works in multisite

Very easy setup. and works with multisite wordpress.
And protects login forms, as well as Contact Form 7 without any changes to Contact forms!
And has doc on how to add this to any other form using PHP code, so one of the best recaptcha plugins, none of the other free plugins have all these features.

Works like a charm

Works really well, was very easy to integrate with my site and overall I’m happy with the result, keep up the great work!
