How to Install IconCaptcha on macOS

IconCaptcha is a captcha plugin for web developers that replaces the traditional text-based captcha with icons. IconCaptcha comes with easy-to-install instructions for Windows and Linux, but this tutorial will guide you through the installation process on macOS.

Prerequisites

Before installing IconCaptcha, you need to have the following installed on your macOS:

• Apache web server
• PHP
• Composer

Step 1: Create a New Project

Start by creating a new project directory inside your DocumentRoot folder, which is usually located at /Library/WebServer/Documents/. You can create a new directory using the following command in your terminal:

$ cd /Library/WebServer/Documents/
$ mkdir myproject

Next, navigate to the newly created directory using the following command:

$ cd myproject

Step 2: Install IconCaptcha Package

To install IconCaptcha package in your project, run the following command in your terminal:

$ composer require iconcaptcha/iconcaptcha

This will download and install the IconCaptcha package in your project directory.

Step 3: Add IconCaptcha to your Application

In your application, add the following lines of code to your HTML form:

<link rel="stylesheet" href="/myproject/vendor/iconcaptcha/iconcaptcha/css/iconcaptcha.css" />
<script src="/myproject/vendor/iconcaptcha/iconcaptcha/js/iconcaptcha.js"></script>

This will add the IconCaptcha CSS and JavaScript files to your HTML form.

Next, add the following PHP code to your form processing script:

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

use IconCaptcha\IconCaptcha;

$config = [
    'public_folder' => '/myproject/vendor/iconcaptcha/iconcaptcha/',
    'fonts_folder' => '/myproject/vendor/iconcaptcha/iconcaptcha/fonts/',
    'icons_folder' => '/myproject/vendor/iconcaptcha/iconcaptcha/images/',
];

$captcha = new IconCaptcha($config);

if ($captcha->validate($_POST['captcha'])) {
    // captcha validation successful
} else {
    // captcha validation failed
}

The public_folder, fonts_folder, and icons_folder variables in the $config array should point to the respective folders in your project where the IconCaptcha package is installed.

Step 4: Test Your IconCaptcha Form

You can now test your IconCaptcha form by submitting it and checking if the validation succeeds or fails. If the validation fails, the $captcha->getErrors() method will return an array of error messages.

Congratulations! You have successfully installed and integrated IconCaptcha in your macOS environment.
