Separate File to define requirements of the plugin

[sumitpore]

Plugins can have specific requirements of

• PHP Version
• WP Version
• Dependent Plugins

In a traditional way, we can add them in the main php file and then write code to check if those requirements are being met or not.

Plugin Boilerplate already supports min PHP Version & WP Version requirement feature. It does not have a dependent plugins requirement feature right now. Of course code this feature can be added in the main plugin's file but that is like adding noise in the main file. The part of checking whether requirements are being fulfilled or not should be handled by a separate class.

The configuration for the plugin can be defined in requirements-config.php file.

Sample config could look like this

<?php
return [

    'min_php_version' => '5.6', // Minimum PHP Version.

    'min_wp_version' => '4.8',  // Minimum WordPress Version.

    'is_multisite_compatible' => false, // True if our plugin is Multisite Compatible.

    'required_plugins' => [ // Plugins on which our plugin is dependent on.

        'Hello Dolly' => [
            'plugin_slug' => 'hello-dolly/hello.php',
            'min_plugin_version' => '1.5',
        ],

    ],

];
