You can directly put site key here or a variable or from database. - 'Form\_ContactForm\_Message': Form\_Field\_ID, via html code. eg. ... `` ... Your Google Recaptcha will display after this form field. - 'no\_debug': Change to debug and not tick the I'm not a robot checkbox will continue submit the form, then you will see the failed message. - 'mt-4 mb-1': Extra css class name for the Google Recaptcha area. For recaptcha v2: Add theme-dark if you want the dark theme instead of the light. Add no-api-js if you already import the recaptcha/api.js. - 'Please tick the reCAPTCHA checkbox first': Frontend alert message if the end user does not tick the checkbox. **Tips:** You can change this value to "v3", it will automatically switch to use Google Recaptcha v3 - Default value of the parameters of the show() method ``` show($site_key,$after_field_id='Form_ContactForm_Comment', $debug='no_debug', $extra_class="mt-4 mb-4", $please_tick_msg="Please tick the I'm not robot checkbox"); ``` ### How to use **Google Recaptcha Invisible** [](#how-to-use-google-recaptcha-invisible) - You need get Google Recaptcha Invisible site key and secret key first. It's different from v2 - Based on above explain, add a sting **invisible** to the Extra css class will do the job. eg. mt-4 invisible mb-1 ``` GoogleRecaptcha::show($SiteKey, 'Form_Field_ID', 'no_debug','mb-2 invisible'); ``` ### Frontend example for **Google Recaptcha v3** [](#frontend-example-for-google-recaptcha-v3) ``` GoogleRecaptcha::show($SiteKey, 'Form_Field_ID', 'no_debug','show-inline-badge mt-4 mb-3','v3'); // or GoogleRecaptcha::showV3($SiteKey, 'Form_Field_ID', 'no_debug'); ``` [![google-recaptcha-v3-default](docs/images/google-recaptcha-v3-default.png "google-recaptcha-v3-default")](docs/images/google-recaptcha-v3-default.png) - Our Google Recaptcha v3 will automatically get g-recaptcha-response value after the page load 10 seconds or the Form\_Field\_ID(eg. Form\_ContactForm\_Message) was clicked. - 'no\_debug': Change to "debug" will always submit an empty g-recaptcha-response to the backend. - 'show-inline-badge mt-4 mb-3': Extra css class name for the Google Recaptcha inline-badge. Remove show-inline-badge will show a right bottom float Recaptcha badge instead inline-badge. [![google-recaptcha-v3-inline](docs/images/google-recaptcha-v3-inline.png "google-recaptcha-v3-inline")](docs/images/google-recaptcha-v3-inline.png) - You need set up Google Recaptcha v3 site key and secret key first. It's different from v2 - If you do not want to use the show() method, You can also use your own code to display the recaptcha for a custom style. Just make sure the form action method is POST, then you can still use below verify() method in your backend script. How to verify it in the backend script ========================================================================= [](#how-to-verify-it-in-the-backend-script) - Import the GoogleRecaptcha class: ``` use GoogleRecaptchaToAnyForm\GoogleRecaptcha; ``` - Put below php code into the form-submitted-method() of your backend php file. ``` GoogleRecaptcha::verify($GoogleRecaptchaSecretKey, 'Google Recaptcha Validation Failed!!'); ``` - Description for above code: - '$GoogleRecaptchaSecretKey': The Google Recaptcha Secret Key of your website. You can directly put secret key here or a variable or from database. - 'Google Recaptcha Validation Failed': Javascript alert message if the verification failed. Set it null or false if you don't want a javascript alert. It will return true or false by the Google recaptcha verification result. Then you can show your own error message. - Default value of the parameters of the verify() method ``` verify($secret_key, $break_msg = null, $recaptcha_score=0.5) ``` - If you are using Google Recaptcha v3, it verify score < 0.5 as a failed result by default. You can set the score if you want a different value. eg. ``` GoogleRecaptcha::verify($SecretKey, 'Google Recaptcha Validation Failed!!', 0.36); ``` Usage example for SilverStripe 4.x/3.x ============================================================================== [](#usage-example-for-silverstripe-4x3x) - Import the GoogleRecaptcha class: ``` use GoogleRecaptchaToAnyForm\GoogleRecaptcha; ``` - Create a function to display the recaptcha in your controller. eg.: ``` public function showGoogleRecaptcha() { return GoogleRecaptcha::show($SiteKey, 'Form_ContactForm_Message', 'no_debug', 'mt-4 mb-1', 'Please tick the reCAPTCHA checkbox first!'); } ``` - Display the recaptcha in the frontend.ss form, add below code to the end of a frontend.ss template. eg. : ``` $showGoogleRecaptcha.RAW ``` - Verify the recaptcha in the controller php file, add below code to the formAction function of your controller. eg.: ``` GoogleRecaptcha::verify($GoogleRecaptchaSecretKey, 'Google Recaptcha Validation Failed!!'); ``` Usage example for Laravel 5.x custom login form ================================================================================== [](#usage-example-for-laravel-5x-custom-login-form) - Include it in your LoginController.php file first: ``` use GoogleRecaptchaToAnyForm\GoogleRecaptcha; ``` - Create a function to display the recaptcha in your LoginController.php eg.: ``` public function showLoginForm() { $showRecaptcha = GoogleRecaptcha::show('site_key', 'password', 'no_debug', 'mt-4 mb-3 col-md-6 offset-md-4', 'Please tick the reCAPTCHA checkbox first!'); return view('auth.login', compact('showRecaptcha')); } ``` - Display the recaptcha in the auth/login.blade.php, add below code to the end of the auth/login.blade.php template. eg. : ``` {!! $showRecaptcha !!} ``` - Verify the recaptcha in the LoginController.php file, add below code for validateLogin. eg.: ``` protected function validateLogin(Request $request) { GoogleRecaptcha::verify('secret_key', 'Google Recaptcha Validation Failed!!'); $request->validate([ $this->username() => 'required|string', 'password' => 'required|string', ]); } ``` Usage example for Wordpress custom form ============================================================================ [](#usage-example-for-wordpress-custom-form) - Include it in your custom form template php file first. Note: Change the correct vendor path for require\_once: ``` require_once(__DIR__ . '/../../../../vendor/autoload.php'); use GoogleRecaptchaToAnyForm\GoogleRecaptcha; ``` - Display the recaptcha in the form template. eg. : ``` echo GoogleRecaptcha::show('site_key', 'input_2_3', 'no_debug', 'mt-4 mb-3 col-md-6 offset-md-4', 'Please tick the reCAPTCHA checkbox first!'); ``` - Verify the recaptcha in the handle form submission method . eg.: ``` require_once(__DIR__ . '/../../vendor/autoload.php'); use GoogleRecaptchaToAnyForm\GoogleRecaptcha; GoogleRecaptcha::verify('secret_key', 'Google Recaptcha Validation Failed!!'); ``` License ======= [](#license) - MIT ### Health Score 32 — LowBetter than 72% of packages Maintenance17 Infrequent updates — may be unmaintained Popularity29 Limited adoption so far Community12 Small or concentrated contributor base Maturity59 Maturing project, gaining track record Bus Factor1 Top contributor holds 100% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
