How to use plugins_loaded action in WordPress

plugins_loaded action

The ‘plugins_loaded’ hook is triggered after all activated plugins have been loaded, providing an opportune moment to override any existing pluggable functions.

To use `plugins_loaded` action, first you have to register it using `add_action`. You can write this code into `functions.php` of your activated theme or in a custom WordPress Plugin.

We at WePlugins, always prefer to create a custom WordPress Plugin while using hooks so nothing breaks when you update your WordPress Theme in the future.

In the below live example, we have defined a function `weplugins_execute_on_plugins_loaded_event` and we registered it using `add_action`. The first parameter `plugins_loaded` is the name of the hook, the second parameter `weplugins_execute_on_plugins_loaded_event` is the name of the function which needs to be called, the third parameter is the priority of calling the hook if the same hook is used multiple times, and the last parameter is the number of arguments (if any) to be passed in the registered function.

Sometimes, you have to remove a registered hook, so you can use `remove_action` to remove `plugins_loaded` action.

Live Example 1: Basic Usage

Below is an example of how you can use this hook.

    function weplugins_execute_on_plugins_loaded_event(){
        // You can write code here to be executed when this action occurs in WordPress website according to your requirements.
    }
    // Add the action
    add_action( "plugins_loaded", "weplugins_execute_on_plugins_loaded_event");
    

Live Example 2: Load Custom Language Files

This example shows how to load custom language files when the plugins are loaded.

    function weplugins_load_custom_language_files() {
        load_plugin_textdomain('your-plugin-textdomain', false, plugin_dir_path(__FILE__) . 'languages/');
    }

    add_action('plugins_loaded', 'weplugins_load_custom_language_files');
    

Live Example 3: Modify Third-Party Plugin Settings

Here’s how you can modify the settings of a third-party plugin once all plugins are loaded.

    function weplugins_modify_third_party_plugin_settings() {
        if (class_exists('Third_Party_Plugin_Class')) {
            // Access and modify settings of a third-party plugin
        }
    }

    add_action('plugins_loaded', 'weplugins_modify_third_party_plugin_settings');
    

To remove a hook callback, use the example below.

    remove_action( "plugins_loaded", "weplugins_execute_on_plugins_loaded_event");
    

Please make sure to provide the same callback function name, priority, and number of arguments while removing the hook callback.
