Free and Pro Versions
Table of contents
Different versions
We use the Free and Pro model where users need only one package for using the specific plugin.
Free
Our free plugins are available in the WordPress plugin directory.
Those plugins are fully functional and are not broken versions designed to sell the Pro upgrade.
Assets loading
When a Free plugin is used as dependency to the Pro plugin the assets can’t be loaded based on URLs from the Free plugin using the plugins_url function because the Free plugin works as a plugin, but is not recognized by WordPress functions as one.
This requires that the vendor folder is in a path that can be accessed by public the internet.
So, for Free plugins we should use the following code to get the correct plugin’s URL:
define('MY_PLUGIN_BASE_PATH', __DIR__);
//...
if (defined('PUBLISHPRESS_CUSTOM_VENDOR_PATH') && defined('PUBLISHPRESS_CUSTOM_VENDOR_URL')) {
$relativePath = str_replace(PUBLISHPRESS_CUSTOM_VENDOR_PATH, '', $relativePath);
define('PUBLISHPRESS_URL', PUBLISHPRESS_CUSTOM_VENDOR_URL . $relativePath . '/');
} else {
define('PUBLISHPRESS_URL', plugins_url('/', 'publishpress/publishpress.php'));
}
Then we need to instruct the clients to specify the vendor path and url constants in their wp-config.php file:
define('PUBLISHPRESS_CUSTOM_VENDOR_URL', 'https://dev.local/wp-content/vendor/');
define('PUBLISHPRESS_CUSTOM_VENDOR_PATH', '/Users/me/Local Sites/dev/app/public/wp-content/vendor/');
Pro
The Pro plugins are available to PublishPress members and can be downloaded from PublishPress.com.
Pro plugins are a complement for the Free plugins, with additional features. We add the Free plugin inside the Pro package and use it as the base for the Pro version. It can be found in the Composer’s vendor dir.
