How to create a custom CakePHP plugin?

Creating a custom CakePHP plugin involves several steps:

1. Create a new directory for your plugin in the plugins directory of your CakePHP project. For example, if your plugin is called MyPlugin, you would create a directory called MyPlugin inside the plugins directory.
2. Create a composer.json file in the root directory of your plugin. This file is used by Composer to manage the dependencies of your plugin. Here is an example composer.json file:

{
    "name": "my-plugin",
    "type": "cakephp-plugin",
    "autoload": {
        "psr-4": {
            "MyPlugin\": "src"
        }
    },
    "require": {
        "php": ">=7.4",
        "cakephp/cakephp": "^4.0"
    }
}

1. Create a src directory inside your plugin directory. This is where you will put your plugin's PHP code.
2. Create a Plugin.php file inside the src directory. This file is the main class of your plugin and should extend CakeCorePlugin. Here is an example Plugin.php file:

1

<?php
namespace MyPlugin;

use CakeCoreBasePlugin;

class Plugin extends BasePlugin
{
}

1. Add any additional PHP files you need for your plugin inside the src directory.
2. Create any necessary configuration files or directories inside the config directory of your plugin.
3. In your CakePHP project's config/bootstrap.php file, load your plugin by adding the following line:

1

$this->addPlugin('MyPlugin');

That's it! Your plugin should now be loaded and ready to use in your CakePHP project.
