jcbones Posted October 9, 2010 Share Posted October 9, 2010 $insert_query="insert into issue values($account,$bookid,'$issuedate',DATE_ADD($issuedate,INTERVAL 15 DAY))"; DATE_ADD is a mysql function, NOT a PHP function. Therefore it must be handled by the DATABASE not the script. Quote Link to comment Share on other sites More sharing options...
