Originally based on mewebstudio/captcha

Installation

Usage with Laravel

Check that new route is working, by visiting '://localhost/captcha/default'

You have to see a captcha image like one of these:

Add captcha to your form, like in the code sample below:

If standard auth in use, add code sample to ./resources/views/auth/login.blade.php.

    <div class="form-group">
        <div class="col-md-6 col-md-offset-4">
            <label>
                <img src="{!! captcha_url() !!}" alt="captcha">
            </label>
        </div>
    </div>
    
    <div class="form-group{{ $errors->has('captcha') ? ' has-error' : '' }}">
        <label class="col-md-4 control-label">Captcha</label>
    
        <div class="col-md-6">
            <input type="text" class="form-control" name="captcha" autocomplete="off">
    
            @if ($errors->has('captcha'))
                <span class="help-block">
            <strong>{{ $errors->first('captcha') }}</strong>
        </span>
            @endif
        </div>
    </div>

Add validation rule to your controller, like in the code sample below:

If standard auth in use, overwrite method validateLogin in ./app/Http/Controllers/Auth/LoginController.php.

    /**
     * Validate the user login request.
     *
     * @param Request $request
     */
    protected function validateLogin(Request $request)
    {
        $this->validate($request, [
            $this->username() => 'required',
            'password'        => 'required',
            'captcha'         => 'required|captcha',
        ]);
    }

Basic Usage

In case you are not happy Laravel user, you may still use this package.

To create captcha, add details to the session and output the image, you may use code like:

<?php

require __DIR__ . '/../vendor/autoload.php';

use Zablose\Captcha\Captcha;

$captcha = (new Captcha())
    ->create([
        'invert' => true,
        'width'  => 320,
]);

$data = [
    'captcha' => [
            'sensitive' => $captcha->sensitive(),
            'hash'      => $captcha->hash(),
        ]
];

// TODO: Add $data to the session.

echo $captcha->png();

To check captcha use:

Captcha::check($sensitive, $captcha, $hash);

Feel the joy and happiness!
