Hi all. I am building an online events registry and have mapped out all the dates between Oct 1 2006 and Dec 31 2030, stored in the database as timestamps incremented by 86400 to give daily slots. I have output the values using the php date function and all is well. Users can enter either one-off or regular events, and I am using a mapping table to tie events to dates as they comprise a many-to-many relationship. I am struggling with some date conversions, however. When a user enters a single event for example, the data is entered into the events table, the inserted id captured, and then the system will look for the relevant record in the dates table, and eventually enter the event id and date id into the mapping table for later joins during the search process. To do this, I call: $date_string = mktime(0,0,0,$_SESSION['month],$_SESSION['day'],$_SESSION['year']) to assemble a timestamp from the supplied user data, and now I need to look for the matching date in the dates table. My problem is in converting between UNIX and mySQL timestamp values. My first attempt to match used this (query extract): "SELECT id FROM dates WHERE FROM_UNIXTIME($date_string) = date" then "SELECT id FROM dates WHERE UNIX_TIMESTAMP(date) = $date_string" neither is working. Am I making some fundamental error here or missing something? Any help appreciated! -- http://www.web-buddha.co.uk http://www.projectkarma.co.uk
