Best Practices & Usage Notes (if applicable): wp_pre_insert_user_data
When using the wp_pre_insert_user_data hook, it’s important to keep in mind that any modifications made to the user data array will directly impact the data that is ultimately saved to the database.

“`php
function custom_user_validation( $user_data ) {
// Perform custom validation or manipulation of user data
if ( empty( $user_data[‘user_email’] ) ) {

}
return $user_data;
}
add_filter( ‘wp_pre_insert_user_data’, ‘custom_user_validation’ );
