Laravel MathCaptcha
===================

[](#laravel-mathcaptcha)

A lightweight, privacy-friendly Laravel package that provides **simple single-digit arithmetic CAPTCHA** for human verification.

> Supports only single-digit operations (1–9) with `+`, `-`, and `×`.

---

Features
--------

[](#features)

- Random single-digit math questions.
- Securely stores answers in server-side session.
- Easy integration with controllers and Blade forms.
- Works without external services or images.
- Compatible with Laravel 10+ / 11+.

---

Installation
------------

[](#installation)

For **local development or testing**, add the package as a path repository in your Laravel app:

```
"repositories": [
    {
        "type": "path",
        "url": "../packages/laravel-math-captcha"
    }
]
```

Require the package:

```
composer require vivekco/laravel-math-captcha:@dev
```

> Laravel 10+ auto-discovers the service provider.
> Optional: publish config if you want to customize defaults:

```
php artisan vendor:publish --provider="Vivekco\MathCaptcha\MathCaptchaServiceProvider" --tag=config
```

---

Usage
-----

[](#usage)

### 1. Generate a Math Question in Controller

[](#1-generate-a-math-question-in-controller)

```
$question = app('mathcaptcha')->generate();
```

- `$question` is a string like `2 + 3`, `4 × 7`, etc.
- The answer is automatically stored in session (`math_captcha_answer` by default).

---

### 2. Blade Form Example (With Error handling)

[](#2-blade-form-example-with-error-handling)

```

    @csrf

    Solve: {{ $question }}

    Submit

 @error('captcha_answer')
        {{ $message }}
@enderror
```

---

### 3. Validation in Controller

[](#3-validation-in-controller)

```
$request->validate([
    'captcha_answer' => ['required', function ($attribute, $value, $fail) {
        if (!app('mathcaptcha')->check($value)) {
            $fail('The math captcha answer is incorrect.');
        }
    }]
]);
```

- `check($value)` returns `true` if correct, `false` if incorrect.

---

Config (Optional)
-----------------

[](#config-optional)

Published config: `config/mathcaptcha.php`

```
return [
    'min' => 1,
    'max' => 9,
    'operations' => ['+', '-', '×'],
    'session_key' => 'math_captcha_answer',
    'allow_negative' => true,
];
```

- `min` / `max`: range of digits.
- `operations`: allowed operators.
- `session_key`: session key storing the answer.
- `allow_negative`: prevent negative results if false.

---

Local Testing
-------------

[](#local-testing)

1. Serve your Laravel app:

```
php artisan serve
```

2. Visit your test route, generate a question, submit correct/incorrect answers.
3. Run package tests (inside package folder):

```

```
