Drupal is a Content Management System (CMS) designed to create everything from tiny to large corporate websites.

Six years ago I wrote a common lookup post to illustrate the effectiveness of things used throughout your applications. Now, I’m updating my student image with a more complete solution to show how to avoid update anomalies.

do {
      ...

You can create create member table, like my example in MySQL 8, or any other table in your MySQL database.

<?php /*
||  Function Name: update_member
*/
function update_member($account_number, $member_type, …
