What is WordPress Hook: updated_option
The updated_option hook in WordPress is used to perform actions after an option has been updated. This hook allows developers to execute custom code when an option is updated, providing a way to modify data or perform other tasks in response to changes in options within WordPress.
Understanding the Hook: updated_option
The updated_option hook is located within the update_option function in WordPress. This function is responsible for updating an option value in the database. The updated_option hook is triggered after the option has been successfully updated, allowing developers to hook into this action and execute custom code.
Hook Parameters (if applicable): updated_option
The updated_option hook accepts three parameters: $option, $old_value, and $new_value. The $option parameter is the name of the option that was updated. The $old_value parameter is the previous value of the option, and the $new_value parameter is the new value that the option was updated to. Developers can use these parameters to perform actions based on the specific option that was updated and the old and new values.
Hook Doesn’t Work: updated_option
If the updated_option hook doesn’t seem to be working, it could be due to incorrect usage or a problem with the update_option function itself. Developers should double-check that the hook is being added correctly and that the update_option function is being used properly. It’s also important to ensure that the option being updated actually exists in the database.
Best Practices & Usage Notes (if applicable): updated_option
When using the updated_option hook, it’s important to keep in mind that any code executed within the hook will run after the option has already been updated. This means that any changes made within the hook will not affect the actual update process. Developers should also be cautious when using the hook to avoid creating infinite loops by updating the option within the hook itself.
Usage Example: updated_option
“`php
function my_updated_option_function( $option, $old_value, $new_value ) {
// Perform custom actions based on the updated option
if ( $option === ‘my_custom_option’ ) {
// Do something with the old and new values
}
}
add_action( ‘updated_option’, ‘my_updated_option_function’, 10, 3 );
“`
