What is WordPress Hook: plugins_loaded
The plugins_loaded hook is a crucial part of the WordPress system that allows developers to execute functions or code after all active plugins have been loaded. This hook is often used to initialize plugin functionality or to perform actions that require all plugins to be loaded.
Understanding the Hook: plugins_loaded
The plugins_loaded hook is located within the wp-settings.php file, which is a core WordPress file responsible for setting up the environment and loading essential files. This hook is triggered after all active plugins have been loaded, making it an ideal place to execute code that depends on plugin functionality.
Hook Parameters (if applicable): plugins_loaded
The plugins_loaded hook does not accept any arguments or parameters. It is simply a trigger point for executing code after all plugins have been loaded.
Hook Doesn’t Work: plugins_loaded
If the plugins_loaded hook doesn’t seem to work as expected, it could be due to the code being added too late in the WordPress initialization process. It’s essential to ensure that the hook is being added in the appropriate location, typically within a custom plugin or theme functions file. Additionally, conflicts with other hooks or plugin-specific issues could also cause the plugins_loaded hook to not work as intended.
Best Practices & Usage Notes (if applicable): plugins_loaded
When using the plugins_loaded hook, it’s important to consider that certain plugin functionality may not be available at this stage of the WordPress initialization process. Developers should carefully test and verify that all required plugins have been loaded before executing code using this hook. Additionally, it’s best practice to use this hook for initializing custom plugin functionality rather than modifying core WordPress behavior.
Usage Example: plugins_loaded
“`php
add_action( ‘plugins_loaded’, ‘my_custom_plugin_init’ );
function my_custom_plugin_init() {
// Initialize custom plugin functionality after all plugins have been loaded
// Add code here
}
