Integrations
Laravel 5.5+ integrations
Package Discovery
Anam\Captcha
utilize the Laravel's package auto discovery feature. So, you don't need to add manually Service provider and Facade in Laravel application's config/app.php. Laravel will automatically register the service provider and facades for you.
Laravel < 5.5 integrations
Captcha comes with a Service provider and Facade for easy integration.
After you have installed the anam/captcha
, open the config/app.php
file which is included with Laravel and add the following lines.
In the $providers
array add the following service provider.
'Anam\Captcha\ServiceProvider\CaptchaServiceProvider'
Add the facade of this package to the $aliases
array.
'Captcha' => 'Anam\Captcha\Facade\Captcha'
You can now use this facade in place of instantiating the converter yourself in the following examples.
Configuration
First, register keys for your site at https://www.google.com/recaptcha/admin
Add RECAPTCHA_SITE_KEY
and RECAPTCHA_SECRET
in .env
file :
RECAPTCHA_SITE_KEY=site_key
RECAPTCHA_SECRET=secret
Run vendor publish to add the captcha.php file to config:
php artisan vendor:publish --tag=CaptchaConfig
By default, The package will try to load keys from environment. However, you can set them manually:
$captcha = new \Anam\Captcha\Captcha('recaptcha_secret');
Blade directives:
// reCAPTCHA v2 @captcha(site_key) // Invisible reCAPTCHA @invisiblecaptcha(site_key)
Usage
Client side
reCAPTCHA V2:
Just add @captcha()
blade directive to the form.
<form method="POST" action="/captcha" id="captcha-form"> {{ csrf_field() }} <label>Name</label> <input type="text" name="name"> <label>Your message</label> <textarea name="message" rows="5"></textarea> <br> @captcha() <br> <input type="submit" value="Submit"> </form>
For more advanced integration, Please visit the following link: https://developers.google.com/recaptcha/docs/display
Invisible reCAPTCHA:
Add @invisiblecaptcha()
directive to the form where you want to appear the submit button. Please note, The @invisiblecaptcha
directive will inject the submit button for you. If you want to style the submit button, .g-recaptcha
class available for you.
<form method="POST" action="/captcha" id="captcha-form"> {{ csrf_field() }} <label>Name</label> <input type="text" name="name"> <label>Your message</label> <textarea name="message" rows="5"></textarea> <br> @invisiblecaptcha() </form>
Caveat: If view has more than one forms, the @invisiblecaptcha()
might not work as it will submit the first form. In these cases, you have to integrate the reCAPTCHA manually.
