You can validate the fields that has to be fulfill with captcha with the rule lucbularavelcaptcha :

public function rules() {
    return [
        'captcha' => 'required|lucbularavelcaptcha:is_caseSensitive'
    ];
}

You can set the parameters is_caseSensitive as 'true' or 'false', the validation will take care or not of matching the case (false by default).

You can generate a captcha in a controller like this :

<?php namespace App\Http\Controllers;

use Lucbu\LaravelCaptcha\Services\Captcha;

class ExampleController {
    public function exampleFunction(){
        Captcha::generateCaptcha();
    }
}

The function will create the captcha and store into the session variable.

You can also get just the image using the route lucbu.laravelcaptcha.image or the sound with the route lucbu.laravelcaptcha.sound.

The player used to play the sound is based on HTML5. (<audio> tag)
