This example logs the date and time a record was deleted and who deleted it.

function tablename_after_delete($selectedID, $memberInfo, &$args){
// log file
$logFile=’deletes.log’;

// attempt to open the log file for appending
if(!$fp = @fopen($logFile, ‘a’)) return;

// write log data: date/time, username, IP, record ID
$datetime=date(‘r’);
fwrite($fp, “$datetime,{$memberInfo[‘username’]},{$memberInfo[‘IP’]},$selectedID\n”);
fclose($fp);
}
