Let’s say that we want to prevent updates to any records in a particular table that are older than 30 days. To do so, we would customize the tablename_before_update() hooks like this:
function tablename_before_update(&$data, $memberInfo, &$args){ // get the creation date of the record $creationDate=sqlValue("select dateAdded from membership_userrecords where tableName='tablename' and pkValue='{$data['selectedID']}'"); // if the record is older than 30 days, deny changes if($creationDate < strtotime('30 days ago')) return false; return true;}
