Responsive Captcha
==================

[![Packagist Version](https://camo.githubusercontent.com/9721cd898e8d977d7ad822fce6dbea52d094634af6173f7f8b85e968a8ccbfce/68747470733a2f2f696d672e736869656c64732e696f2f7061636b61676973742f762f7468656f646f72656a622f726573706f6e736976652d636170746368612e737667)](https://packagist.org/packages/theodorejb/responsive-captcha)

Prevent form spam by generating random, accessible arithmetic and logic questions.

Examples:

- "What is the fourth letter in snowboard?"
- "What is the sum of four and six?"
- "What is eight multiplied by two?"
- "Which is smallest: sixty-six, one hundred, or twenty-two?"

Users can respond with either the numeric or textual version of an answer (e.g. "16" or "sixteen").

For background info on this project, see my blog post:

Install via Composer
--------------------

[](#install-via-composer)

`composer require theodorejb/responsive-captcha`

Usage
-----

[](#usage)

1. Generate a random question:

    ```
    use function theodorejb\ResponsiveCaptcha\{randomQuestion, checkAnswer};

    $qa = randomQuestion();
    $realAnswer = $qa->getAnswer(); // save somewhere (e.g. in session or encrypted single-use token)
    ```
2. Display question in form:

    ```

    ```
3. Check whether the user's response is correct:

    ```
    $answer = filter_input(INPUT_POST, "captcha");

    if ($answer !== null) {
        if (checkAnswer($answer, $realAnswer)) {
            // code to execute if the captcha answer is correct
        } else {
            // the answer is incorrect - show an error to the user
        }
    }
    ```
