wpconstructor / plugin-version
Gets the plugin version from the main file and verifies that the required PHP and WordPress versions are satisfied. If the requirements are not met, it returns false and triggers an admin notice.
README
WPConstructor Plugin Version is a lightweight PHP utility for WordPress plugins that allows you to retrieve the version of a plugin’s main file safely, without triggering translation errors or requiring manual inclusion of plugin.php on the frontend.
It also includes built-in checks for PHP and WordPress version requirements, and displays an admin notice if the current environment does not meet the requirements. You can optionally force the plugin to always run using a constant.
Features
- Safely retrieves the version of a plugin’s main file.
- Avoids
get_plugin_data()issues before theinithook. - No need to include
plugin.phpmanually on the frontend. - Checks PHP and WordPress version requirements.
- Shows admin notice to users with
install_pluginscapability if requirements are not met. - Optionally force plugin execution even if requirements are not met via a constant.
Installation
Install via Composer:
composer require wpconstructor/plugin-version
Or download from GitHub as a ZIP and include it in your plugin manually.
Usage
Add the following code to your main plugin file:
$main_file = __FILE__; $plugin_version = require __DIR__ . '/vendor/wpconstructor/plugin-version/src/includes/plugin-version.php'; // If requirements are not met and the constant WPCN_PLUGIN_VERSION_ALWAYS_RUN is not set or false, stop execution. if ( false === $plugin_version ) { return; // Stop execution if requirements are not met. } // Use the plugin version, e.g., define a constant. define( 'MY_PLUGIN_VERSION', $plugin_version );
Setting
WPCN_PLUGIN_VERSION_ALWAYS_RUNtotruewill bypass PHP and WordPress version checks, ensuring the plugin always loads.
Admin Notice
If the current PHP or WordPress version does not meet the requirements, an admin notice is displayed only for users with the install_plugins capability, unless WPCN_PLUGIN_VERSION_ALWAYS_RUN is set to true.
