How to use after_db_upgrade action in WordPress

after_db_upgrade action

Fires on the next page load after a successful DB upgrade.

To use the after_db_upgrade 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_after_db_upgrade_event and registered it using add_action. The first parameter after_db_upgrade is the name of the hook, the second parameter weplugins_execute_on_after_db_upgrade_event is the name of the function that 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 the after_db_upgrade action.

Parameters

• No parameters

Live Example 1: Registering the Hook

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

    function weplugins_execute_on_after_db_upgrade_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("after_db_upgrade", "weplugins_execute_on_after_db_upgrade_event");
    

Live Example 2: Removing the Hook

To remove a hook callback, use the example below.

    remove_action("after_db_upgrade", "weplugins_execute_on_after_db_upgrade_event");
    

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

Live Example 3: Custom Functionality on DB Upgrade

You can also add custom functionality that runs after a DB upgrade. Here’s an example:

    function weplugins_custom_db_upgrade_task() {
        // Custom code to execute after DB upgrade, like updating custom tables or settings.
    }
    add_action("after_db_upgrade", "weplugins_custom_db_upgrade_task");
